Is a maintenance inspection basically a buyer’s inspection for homeowners, or is it something different? Most homeowners do not know what is actually included, and that knowledge gap carries real risk. When minor roof leaks, electrical issues, or foundation settling go unnoticed, those hidden defects quickly become budget-breaking repairs.

This guide answers that question directly. You will find a system-by-system checklist of what gets inspected, where standard boundaries end, when to schedule specialized add-on testing, and how to prioritize your final report to keep your home safe.

Read on for what a professional maintenance inspection is actually designed to do.

 

What Happens During a Home Maintenance Inspection?

Imagine catching a faint, musty smell in your basement or noticing a guest bathroom sink draining slowly. Instead of calling expensive specialty contractors, a preventive checkup offers an unbiased, non-alarmist evaluation.

Knowing what to expect during a home inspection helps you prepare. The process is a visual, non-invasive assessment of accessible areas, focusing on safety and material defects. The inspector explains findings in real time and documents issues with photos, examining:

• Exterior elements: Siding, grading, gutters, and roofline.
• Interior systems: Electrical outlets, plumbing fixtures, and heating and cooling units.
• Attic, crawlspace, and basement cavities.

To prepare, confirm all utilities are on and that you have cleared access to your electrical panel, attic hatch, and water heater. Schedule a maintenance checkup every few years, or sooner if you have aging systems, recurring moisture issues, or severe storm damage.

 

Your Home Maintenance Inspection Checklist: System by System

Data shows most major home repair surprises come from a handful of primary systems: roofing, water, electrical, and HVAC. To identify these risks systematically, professional inspectors evaluate your home’s core components and report visible material defects and safety hazards before they escalate.

The assessment covers:

• Roof: Shingles, flashing, visible damage, and signs of active leaks from the attic side.
• Exterior: Siding, grading, drainage, visible penetrations, and deck or stair safety.
• Basement and Foundation: Structural cracking, wall movement, moisture staining, and support post stability.
• Heating: Safe unit operation, venting issues, and routine maintenance red flags.
• Cooling: Basic system operation when weather permits, condensate drainage, and exterior wear.
• Plumbing: Visible supply and drain piping, fixture function, slow leaks, and water heater condition.
• Electrical: Main panel safety, visible wiring hazards, GFCI or AFCI presence, and open junction boxes.
• Fireplace: Visible firebox cracking and damper function (this is not a chimney scan).
• Attic and Insulation: Insulation depth, proper ventilation pathways, and signs of moisture or mold-like growth.
• Interior and Openings: Door and window operation, wall moisture stains, and safety detector presence.

This checklist covers critical structural and mechanical components, but the evaluation stays non-invasive. Understanding what falls outside an inspector’s physical reach helps manage expectations heading into the visit.

 

What a Home Maintenance Inspection Does Not Cover

A thorough inspection can still miss significant problems if they are concealed or require specialized testing. Professional maintenance evaluations are strictly non-invasive. Inspectors examine accessible structural elements and home systems, but will not tear open drywall, dismantle HVAC units, or dig up underground lines.

While a homeowner’s DIY checklist focuses on changing filters and cleaning gutters, a professional evaluation identifies subtle warning signs of structural movement, hazardous wiring configurations, and hidden moisture patterns.

To bridge these coverage gaps, consider specialized testing based on your property’s age and known risk factors:

• Radon Testing ($130): A critical health screening for this invisible, odorless soil gas.
• Termite/WDI Inspection (Starting at $95): Identifies active wood-destroying pest activity and structural damage.
• Sewer Scope: Recommended for older homes with mature trees near the main lateral line.
• Mold and Moisture Diagnostics: Necessary when facing persistent musty odors or staining.

If you are currently buying or selling, a residential home inspection remains your best option for a full transaction-ready report.

Schedule Your Inspection

How to Prioritize What Your Inspection Report Finds

Imagine opening your report to find a slow plumbing drip, a missing kitchen GFCI outlet, and an overflowing gutter. Which requires immediate attention, and which can wait?

Sort your findings into this four-tier framework:

• Priority 1: Safety Now. Immediate hazards like active electrical risks, combustion venting issues, or loose stair railings.
• Priority 2: Active Damage. Time-sensitive issues like moisture intrusion, soil grading problems, or failing roof flashing that will cause rot if ignored.
• Priority 3: Preventive Maintenance. Important mid-term tasks like HVAC servicing or water heater end-of-life planning.
• Priority 4: Monitor/Cosmetic. Minor hairline concrete cracks or peeling trim paint.

In Delaware and Southeastern Pennsylvania, local climate shapes these priorities. High summer humidity and heavy rainfall require immediate crawlspace moisture control and proper gutter drainage to protect foundations. Winter freeze-thaw cycles make exterior caulking and unconditioned pipe protection critical. In historic pockets of Wilmington and Chadds Ford, older electrical components and aging roofs need extra scrutiny.

Addressing a $150 gutter problem now prevents a $5,000 foundation repair later. Use your findings to build a 12-month repair plan and a 5-year budget. A seasoned local inspector can spot patterns common to homes in this region.

 

Turn Your Maintenance Inspection Into a Repair Plan

Knowing what a home maintenance inspection covers helps you protect your largest asset. Use this checklist to turn your report into an actionable preservation plan:

1. Establish a baseline: Use the visual inspection to get an objective snapshot of your major structural and mechanical systems.
2. Identify testing gaps: Standard reviews are non-invasive. Schedule specialized add-ons like radon or termite testing to address hidden hazards.
3. Prioritize the findings: Group issues by urgent safety risks, active moisture damage, and deferred maintenance.
4. Structure your finances: Create a 12-month immediate repair plan alongside a long-term capital replacement budget.
5. Determine future cadence: Re-evaluate your home every three to five years, or immediately following severe storm events.

Frequently Asked Questions About Home Maintenance Inspections

Is a home maintenance inspection the same as a buyer’s home inspection?

No, they serve different purposes. A buyer’s inspection evaluates a property’s condition for real estate transaction negotiations. A maintenance inspection is a preventive health checkup for current homeowners to plan future upkeep. Both evaluate the same core systems, but the homeowner context focuses on long-term preservation.

Can I use a home maintenance inspection checklist and skip the professional inspection?

You can use DIY checklists for seasonal upkeep like cleaning gutters, but they cannot replace a professional evaluation. Professional inspectors identify safety and material-defect patterns that homeowners miss. Local experts at Preferred Home Inspections use specialized tools to detect hidden electrical risks and structural settling.

How long does a home maintenance inspection take?

A home maintenance inspection typically takes between two and three hours. The exact duration depends on your home’s square footage, age, and the accessibility of key areas like attics or crawlspaces. It also depends on how many specific concerns you want to walk through with the inspector.

What is not included in a routine home inspection checklist?

Standard inspections exclude invasive testing, underground systems, and cosmetic issues. Inspectors will not dismantle HVAC systems or open drywall. Standard checklists also omit specialty assessments like radon or termite testing.

What should I do if my inspection report feels like a long to-do list?

Do not panic. Every inspection report contains multiple findings. Prioritize the list by starting with immediate safety hazards, followed by active water damage, and finally preventive tasks. Ask your inspector to clearly distinguish between what needs fixing now versus what you can simply monitor.

One step can stop a “great-looking” home from becoming a five-figure surprise: a professional home inspection. The importance of home inspections goes beyond curb appeal — a qualified inspector surfaces hidden defects before you are locked into a contract, giving you a clear picture of what you are actually buying.

For buyers, this provides essential due diligence and a strong negotiating lever. For sellers, it delivers pre-listing certainty that prevents deals from falling apart at the last minute. For investors, a thorough inspection is the only reliable way to plan for future capital expenditures.

This guide explains what a standard inspection covers and where the reporting boundaries lie. You will learn how to identify high-ROI moments for negotiation and repair planning, plus when to add specialized services like radon testing, termite (WDI) inspections, or sewer scopes to your protection plan.

Understanding the Limits: What Your Inspection Actually Covers

Contrary to popular belief, a home inspection is not a guarantee that your house is defect-free or that the HVAC won’t fail next year. It is a visual, non-invasive assessment of accessible areas at a specific point in time. The primary importance of home inspections lies in identifying material defects — issues that significantly impact safety, structural integrity, or the operation of expensive systems.

Because the process is non-destructive, inspectors do not open walls or dismantle equipment. If a roof is snow-covered or a basement is blocked by heavy boxes, those areas remain inaccessible. Think of your report as a professional risk-management tool designed to inform your purchase decision, not a future-proof warranty.

With expectations set, here is a look at what a standard inspection scope typically includes.

Standard Home Inspection: What’s Included and What’s Excluded

A standard inspection provides a visual assessment of the home’s major systems and physical structure. Our residential home inspections follow a rigorous protocol to document core property health.

The Standard Inspection Covers:

• Roof and Attic: Shingles, flashing, vents, and visible insulation.
• Electrical: Main panels, breakers, and a sampling of outlets and switches.
• Plumbing: Visible supply lines, drains, and the water heater.
• HVAC: Heating and cooling equipment (operational checks performed as weather conditions allow).
• Surfaces: Doors, windows, and walls, plus exterior grading and drainage.
• Structure: Visible foundation, basement, and crawlspace.

Common Exclusions:

Standard inspections exclude radon, mold, and termite (WDI) tests unless ordered separately. They also cannot identify defects hidden behind finished walls. Confirm the scope in writing before hiring. If you are buying an older home in Wilmington or Middletown, adding a sewer scope or radon test addresses the most common local risks.

The Financial Power of Home Inspections: ROI and Negotiation Leverage

While only 7% to 15% of real estate deals fall through entirely, a significant majority are successfully renegotiated based on professional findings. The true importance of home inspections lies in their ability to translate physical defects into objective dollar outcomes before you reach the closing table.

Three common financial paths follow an inspection:

• Direct Repairs: The best route for immediate safety hazards, such as faulty electrical panels or active plumbing leaks.
• Closing Credits: Ideal for large, non-urgent items like an aging roof — this lets you control repair quality after move-in.
• The Exit: The inspection contingency acts as a legal off-ramp if the structural or financial risk exceeds your comfort level.

Waiving an inspection transfers 100% of the financial risk to the buyer. You own every hidden defect the moment you sign. A safer middle ground is an “informational-only” inspection, which preserves your right to walk away while signaling to the seller that you will not nitpick minor repairs.

The ROI is often immediate. A sewer scope typically costs $150 to $300, yet it can identify line collapses that cost $15,000 to replace. For investors, these reports function as a capital expenditure forecast, turning unknown risks into predictable line items.

Beyond the Price Tag: Identifying Hidden Safety Hazards

A beautiful home can hide dangerous secrets. A freshly painted basement might conceal an outdated electrical panel known for fire risks. While many view the importance of home inspections primarily as a negotiation tool, the primary goal is identifying hazards before they become emergencies.

Our inspectors evaluate several high-stakes categories:

• Electrical Safety: Identifying overloaded panels and missing GFCI protection in kitchens and bathrooms.
• Combustion Risks: Detecting improper gas venting or unsafe appliances that pose carbon monoxide risks.
• Structural Moisture: Spotting moisture intrusion or poor ventilation in attics and crawlspaces that triggers wood rot, pests, or mold.

Radon testing is also a smart health screening to add. The CDC reports that radon is the second leading cause of lung cancer in the U.S. At $130, it is one of the lowest-cost protections available for your family’s long-term safety.

When to Use Specialized Inspection Add-Ons

A general assessment builds the foundation of your understanding, but the most expensive repairs often hide where a visual check cannot reach. Add-ons provide targeted data for specific structural or health risks.

• Radon Testing ($130): Important for Delaware homes where this odorless gas is the second leading cause of lung cancer. It measures current levels but cannot predict future shifts.
• Termite/WDI ($95): Required by many lenders for wood-framed structures. This service flags active infestations but cannot see inside solid structural beams.
• Sewer Scope: Worth adding for homes over 20 years old or properties near mature trees. It reveals underground line collapses that standard plumbing tests miss.
• Thermal Imaging: Identifies hidden moisture intrusion or insulation gaps without opening walls.

Preferred Home Inspections draws on 30 years of local experience to help you prioritize these services based on visible red flags and property age.

Your Inspection Action Playbook

How do you turn a 40-page technical document into a clear plan? Start by scheduling early in the contingency window so there is time for specialist follow-ups. Confirm add-ons like radon or termite testing upfront. Attend the walkthrough if possible — it is the best time to see what happens during an inspection firsthand and ask your inspector to point out main shutoffs and distinguish between “fix now” and “monitor later” items.

After the visit, triage your digital report into three tiers: (A) immediate safety hazards, (B) major systems like HVAC or roofing, and (C) general maintenance. Understanding your report — with its photos and prioritized summaries — reduces confusion and lets you request accurate repair estimates to negotiate based on objective data.

Using Your Inspection Report for a Smarter Real Estate Deal

An inspection report is a financial instrument, not just a list of flaws. Whether you are buying a home in Newark or selling a farmhouse in Chadds Ford, you can convert physical findings into negotiation power or budget certainty.

• Buyers: Protect your downside. Prioritize safety and major system health over cosmetic fixes to keep the deal moving without inheriting a money pit.
• Sellers: Gain pre-list certainty. Identifying and addressing high-impact issues early prevents aggressive last-minute price drops and builds immediate buyer trust.
• Investors: Use the report as a professional capital expenditure underwriting tool. Categorize “monitor later” items to build an accurate five-year maintenance and cash-flow model.

Your Five-Step Action Plan:

• Confirm the inspection scope and exclusions in writing before the appointment.
• Add specialized tests — radon or termite — based on property age and local risks.
• Attend the walkthrough or schedule a phone debrief for professional context on major findings.
• Gather repair estimates for high-priority items to fuel price negotiations or credits.
• Save the photo-rich report as your long-term home maintenance roadmap.

Frequently Asked Questions

What does a home inspection cover in plain English?

A standard home inspection covers the major visible systems and structural components of a house, including the roof, foundation, electrical panels, visible plumbing, and the heating and cooling systems. The inspector evaluates these areas to identify safety hazards or material defects that could be expensive to fix. Because the work is entirely visual, the inspector only examines accessible areas and will not move heavy furniture or cut into walls.

What is not included in a standard home inspection?

Standard inspections typically exclude specialized testing for radon gas, mold, wood-destroying insects like termites, and sewer line conditions. They also do not cover aesthetic issues, concealed defects behind finished walls, or underground systems like septic tanks. Preferred Home Inspections offers these evaluations as add-on services. Request specific tests like radon or termite inspections if the property’s age or location suggests a higher risk.

Do I need a home inspection if the house is move-in ready?

Yes. Even a house that looks perfect can have hidden, high-cost issues like cracked heat exchangers, outdated wiring, or structural moisture in the attic. Fresh paint and new flooring often mask problems that only a professional eye can spot. An inspection provides a risk-reduction plan and helps you understand the remaining lifespan of expensive mechanical systems.

Is it ever a good idea to waive the home inspection contingency?

Waiving the inspection contingency is generally discouraged because it transfers 100 percent of the financial risk for hidden defects to the buyer. In competitive markets, a safer alternative is requesting an “informational-only” inspection or a shorter contingency window. Both let you understand the home’s true condition while preserving the right to walk away if major structural or safety issues turn up.

Do new construction homes need inspections too?

New construction homes need inspections because workmanship errors, missing insulation, and improper system installations happen regularly during fast-paced builds. Smart buyers schedule a “pre-drywall” inspection to see the framing and electrical work, then a final inspection before closing. Book an “11-month warranty” inspection to catch settling issues or system failures before the builder’s one-year coverage expires.

How long does a home inspection take and when do I get the report?

Most home inspections take two to four hours depending on the property’s size, age, and complexity. Larger or older homes require more time to evaluate crawlspaces and aging mechanical systems. Preferred Home Inspections delivers a detailed, photo-rich digital report via Spectora within 24 hours of the site visit. Always confirm the turnaround time with your inspector to meet your contract negotiation deadlines.

Preventing termite damage starts long before you see visible signs like soft wood or blistering drywall. In most cases, termites are drawn in by excess moisture and easy access points, which makes early prevention one of the best ways to protect your home.

This guide explains how to prevent termite damage by reducing common risk factors, correcting common misconceptions, and knowing when professional help is needed. It also covers pretreatment options for new construction and the warning signs that can point to a developing infestation.

Schedule Your Termite Inspection

Match Your Prevention Strategy to the Termite Species

Did you know that treating your soil won’t stop termites that fly directly into your attic? Knowing how to prevent termite damage effectively requires matching your strategy to the specific species targeting your property.

• Subterranean Termites: Living in soil, these pests build mud tubes and thrive on moisture.
• The Fix: Maintain a 6-inch soil-to-wood gap and divert gutters 3 feet from the foundation to keep the perimeter dry.
• Drywood Termites: These enter through rooflines and live entirely inside dry wood members.
• The Fix: Seal eaves with caulk and keep all exterior wood painted or stained to block entry.

If you are unsure which threat you face, address moisture today and schedule a professional termite inspection for confirmation.

How to Prevent Termite Damage: A Prioritized Checklist

Finding a mud tube on your foundation often traces back to a missing $10 downspout extension. Termites follow moisture and concealed access rather than appearing by chance. This is how to prevent termites and prevent termite damage by removing the conditions they need to survive.

Use this prioritized list to harden your home:

• Fix Moisture (Highest ROI): Repair leaking spigots and make sure AC lines discharge three feet from the slab.
• Improve Drainage: Grade soil away from the house to prevent water pooling near foundation walls.
• Eliminate Wood-to-Soil Contact: Siding and deck posts should never touch dirt. Use concrete piers or metal anchors.
• Maintain Inspection Gaps: Keep six inches of foundation clear of mulch to spot mud tubes easily.
• Store Wood Properly: Keep firewood 20 feet from the structure and elevated.

Avoid “termite-proof” mulch gimmicks. Focus on perimeter dryness to make your property less attractive to foraging colonies. Specific maintenance reduces the likelihood that a colony identifies your foundation as a viable entry point.

When to Call a Pro: Choosing Your Termite Defense

Knowing when to move from DIY prevention to professional treatment can help protect your home from expensive termite damage. It is time to call an expert right away if you notice:

• Mud tubes on foundation walls
• Swarming insects near your home
• Frass, which looks like small sawdust-like pellets
• Wood that sounds hollow when tapped

A professional termite inspection gives you a closer look at structural areas where damage may be developing. It can also create a documented baseline of your home’s condition, especially when included as part of a residential inspection.

Professional termite protection often includes:

• Liquid soil barriers for immediate protection
• Baiting stations for long-term colony control

Subterranean termites, which are common in Delaware and Southeastern Pennsylvania, usually require soil-based treatment methods. Before signing a termite contract, it is also important to understand that many termite bonds cover re-treatment but not structural repairs. Since homeowners insurance often does not cover termite damage, regular professional inspections can be one of the best ways to protect your investment.

Building It Right: The Two-Layer Strategy for Termite Pretreatment

Subterranean termites cause $5 billion in U.S. property damage annually. Knowing how to prevent termite damage starts with termite pretreatment — protection installed before the foundation is poured. A professional strategy requires both a chemical soil pretreatment and physical barriers like mesh or collars at plumbing penetrations. These systems typically fail at unsealed gaps or overlaps, making quality control during installation essential. Developers should provide an as-built protection sheet to prevent future landscaping or drilling from breaching these barriers. Schedule a home maintenance inspection in Delaware to make sure soil bridging or moisture doesn’t undermine your pretreatment.

A 4-Week Action Plan to Prevent Termite Damage

Termite prevention is most effective when you prioritize the primary drivers of infestation: moisture, direct wood-to-soil contact, and hidden structural bridges. Since insurance rarely covers termite damage, implementing a systematic defense over the next month protects both your structure and your equity.

Week 1 (Immediate DIY): Focus on the perimeter. Repair pipe leaks and make sure downspouts discharge at least three feet from the foundation. Eliminate wood-to-soil contact on deck posts or lattice and clear mulch build-up to maintain a six-inch inspection gap below your siding.

Weeks 2–3 (Verification): Conduct a focused walk-around of your crawlspace, basement, and exterior walls. Search for mud tubes, sawdust-like frass, or blistering paint. If you are buying a home or lack a recent record of your home’s condition, schedule a Wood-Destroying Insect (WDI) inspection to establish a professional baseline.

Week 4 (Long-term Defense): If signs of activity exist, consult a professional regarding liquid barriers or baiting systems. Set a seasonal reminder for moisture checks and an annual perimeter review.

Frequently Asked Questions About Termite Prevention

What deters termites the most — are there natural deterrents that work?

Dryness, a lack of wood-to-soil contact, and clear inspection gaps are the most effective deterrents. While some suggest cedar mulch or orange oil, these natural options are rarely reliable as a primary defense for your home. Termites are incredibly persistent and can often bypass aromatic wood or topical oils. Focusing on physical barriers and moisture control provides a much more solid shield for your foundation.

How can I prevent termites if my house has a crawlspace or basement?

Prevention in crawlspaces and basements centers on aggressive moisture control through proper ventilation or dehumidification. You must also make sure that sill plates and rim joists remain accessible for visual inspection to spot mud tubes early. Keep all storage boxes and wood debris away from interior foundation walls. Any plumbing leak above must be repaired immediately to prevent dampening the wood structures below.

Do I need termite pretreatment for new construction?

Yes, termite pretreatment is essential in high-risk areas and is easiest to install before the slab or foundation is finished. This typically involves a chemical soil treatment combined with physical barriers, such as mesh or collars, at plumbing penetrations. Always ask your builder for documentation on exactly what was installed and where the treatment was applied. This record is vital for maintaining future warranties and knowing where barriers might be breached during landscaping.

How often should I get a termite inspection?

Homeowners should schedule a professional termite inspection at least once a year as a baseline. You should also request an inspection after major renovations, significant drainage changes, or severe moisture events like basement flooding. Ongoing prevention pairs well with a periodic home maintenance inspection to make sure your property’s defenses haven’t been compromised by shifting soil or aging seals.

What is a termite bond, and does homeowners insurance cover termite damage?

A termite bond is a service agreement with a pest company that usually covers re-treatment, though many exclude the cost of structural repairs. Most standard homeowners insurance policies do not cover termite damage because it is classified as preventable maintenance. Read the fine print of any bond carefully to understand what specific areas or species are excluded. Relying on insurance for a future infestation often leads to expensive out-of-pocket costs.

If I had termites treated, what prevents them from coming back?

Successful treatment does not provide permanent immunity, so maintaining moisture control and soil clearance is necessary to prevent a return. Chemical barriers also degrade over several years, requiring periodic re-application to remain effective. Annual inspections are the best way to catch a reinfestation before the colony can cause significant structural harm. Never disturb the treated soil zone or add mulch that bridges the gap between the ground and your siding.

Protecting your home from termites comes down to consistent moisture control, eliminating wood-to-soil contact, and staying ahead of problems with regular inspections. When in doubt, a professional WDI inspection gives you a clear picture of your property’s risk and a documented baseline for the future.

Get a Free Home Assessment

Buying a home is one of the most important financial decisions you will ever make. It’s an exciting time, but it can also be a lot. You want to love the house, but you also need to know that it is safe, solid, and worth the investment.

This is where the home inspection becomes your most valuable tool.

However, many buyers are surprised to learn that one inspection does not always cover everything. Depending on the property’s age, location, and condition, you may need a team of specialists to look more closely. Understanding the different types of home inspections available helps you uncover common underlying issues before you sign on the dotted line.

Below is a comprehensive guide to help you navigate the various inspections you might encounter during a real estate transaction.

What Are the Types of Home Inspections?

From the essential baseline checks to specialized assessments for unique hazards, here is a breakdown of the different inspections you should consider to make sure no stone is left unturned.

1. The Standard “General” Home Inspection

This is the baseline inspection performed during a real estate transaction. Almost every buyer starts with a residential home inspection.

A licensed home inspector performs a visual examination of the home’s accessible structural parts and major systems. This includes a visual check of the roof, the foundation, plumbing and electrical systems, windows, and doors. They will also inspect the HVAC (Heating, Ventilation, and Air Conditioning), the attic, and insulation.

This gives you a broad overview of the home’s condition.

2. Structural & System-Specific Inspections

If a general inspector finds a problem beyond their expertise, they refer you to a specialist. For example, foundation cracks or a sagging roof may require a structural inspection by a licensed engineer.

Specialized inspections are also needed for specific systems, often for safety or access. A detailed, climb-on or drone roof inspection is necessary for slate, tile, or steep roofs. Homes with a fireplace need a chimney inspection by a certified sweep to check the flue for creosote, structural integrity, and proper ventilation.

For mechanical systems, consider an electrical inspection, especially for homes over 40 years old, to check for knob-and-tube wiring or old fuse boxes. An HVAC inspection is more detailed; a licensed technician will disassemble the unit to check the heat exchanger and coolant levels. This is particularly important in older properties, where inspectors frequently encounter common electrical issues in Delaware homes, including outdated wiring, overloaded panels, or improper grounding.

3. Environmental & Health Hazard Inspections

These inspections look for invisible or hidden dangers that can affect the health of the occupants. Because these issues are often undetectable by sight or smell, specific testing is required.

• Radon Testing: Checks for the presence of radon, a radioactive gas that rises from the soil and can cause lung cancer. Radon testing is highly recommended in basements.
• Mold Inspection: Checks air quality and surfaces for mold spores. This is often recommended if the house has a musty smell or a history of water damage.
• Asbestos Inspection: Vital for homes built before 1980; this checks insulation, floor tiles, and pipe wrapping for asbestos fibers.
• Lead-Based Paint Inspection: Essential for safety in homes built before 1978.

4. Plumbing & Water Inspections

Water is one of the most destructive forces in a home, so making sure the plumbing is sound is critical. One of the most important add-ons is the sewer scope inspection. A camera is snaked through the main sewer line to the street to check for tree root intrusion, collapses, or clogs. This is highly recommended for older homes where clay or cast iron pipes may be failing.

If the property is not on city water, you will need a septic system inspection to check the tank levels, baffles, and the health of the leach field. You should pair this with water quality testing to check for bacteria (E. coli), nitrates, lead, and arsenic.

A well inspection is also necessary to check the mechanical pump, pressure tank, and water yield to ensure you have adequate pressure.

5. Exterior & Grounds Inspections

The land around the home is just as important as the structure itself. A pest/WDO inspection checks for Wood Destroying Organisms, specifically termites, carpenter ants, and powder post beetles. This is often required by lenders to ensure the structural integrity of the wood.

6. Insurance & New Construction Inspections

Insurance companies often require specific reports to bind a policy. A 4-point inspection looks strictly at the Roof, HVAC, Plumbing, and Electrical systems (common for homes over 20-30 years old). A wind mitigation Inspection verifies construction features that increase resistance to high winds, such as hurricane straps, which can result in significant insurance discounts.

For new builds, phase inspections are critical:

• Foundation: Checked before pouring concrete.
• Pre-Drywall: Checks framing and rough-ins before walls are closed.
• Final: The standard inspection before closing.
• 11th Month Warranty Inspection: Performed one month before the builder’s 1-year warranty expires to catch defects the builder must fix.

7. Thermal Imaging (Infrared) Inspection

While often part of a general inspection, this can be a standalone service, depending on the inspector. It uses infrared cameras to detect temperature differences that indicate hidden water leaks behind walls, missing insulation, or overheating electrical components.

8. Home Maintenance Inspection

A home maintenance inspection is designed for homeowners who want to stay ahead of costly repairs rather than react to them. Unlike a pre-purchase inspection, this focuses on wear-and-tear items, system performance, and developing issues that may not yet be visible or urgent. The inspector evaluates roofing, exterior drainage, HVAC efficiency, plumbing fixtures, electrical components, attic ventilation, insulation, and moisture-prone areas like basements and crawlspaces.

Home inspections play a critical role in protecting one of your largest financial investments by uncovering hidden issues that could compromise safety, performance, or long-term value. The purpose of home inspections is to give homeowners clear, objective insight into the condition of their property, allowing informed decisions before minor concerns escalate into costly repairs.

 

What’s Included in a Home Inspection?

While the list above covers specialized services, it is helpful to understand exactly what happens during the standard general home inspection. A professional home inspector follows a strict Standards of Practice to ensure nothing is missed.

According to standard industry guidelines, here is exactly what your inspector will review:

Structural Systems

The inspector examines the “bones” of the house. This includes the foundations, grading, and drainage around the exterior to ensure water flows away from the home. They will inspect basements, walkways, and the structural integrity of floors, walls, and ceilings. If the home has a crawl space, they will check it for shifting soil or damaged support beams.

Roofing

This is a critical visual assessment of the roof coverings (shingles, tile, or metal), drainage systems like gutters and downspouts, and flashings around skylights. They also check chimneys and other roof penetrations.

Note that while they check the exterior condition, this is different from a Level 2 internal chimney inspection, which requires a camera.

Electrical Systems

Safety is the priority here. The inspector reviews the service entrance and panels, branch circuits, and connected devices and fixtures. They verify that the home has working smoke and carbon monoxide detectors and ensure your outlets are GFCI-protected to prevent shock, especially in wet areas like kitchens and bathrooms. This thorough check of the electrical systems is vital, especially in older homes.

Plumbing

The inspector checks all fixtures and faucets, water supply systems, and drain, waste, and vent systems. They will test the water heater to ensure it is heating properly and venting safely. They also inspect flues, chimneys related to plumbing, and any sump pumps or fuel storage and distribution systems present on the property.

Heating, Ventilation, and Air Conditioning Systems

To ensure your comfort year-round, the inspector tests the heating and cooling system equipment. They will look at the condition of the ducts, vents, and flues to ensure air is flowing correctly and safely throughout the home.

Appliances

Built-in appliances are tested for basic functionality. This includes the dishwasher, garbage disposal, range hood, range or oven, cooktop, and microwave. They also check the trash compactor, bathroom exhaust fans, and the garage door operator to ensure safety sensors are working.

Moisture Problems

Finally, the inspector looks for signs of active water intrusion or past water damage. While this is a visual check for dampness and staining, it can reveal underlying issues. If they spot significant moisture, they may recommend a specialized mold inspection to test the air quality for invisible spores.
