By Cortland Bradley, owner and licensed Delaware home inspector (ASHI member) – Updated September 2026
A standard home inspection in Delaware costs between $350 and $425 for most single-family homes; Preferred Home Inspections’ residential inspection starts at $425. The final price depends on the size of the home, its age, the property type, and any add-on services ordered alongside the inspection, such as radon testing or a termite inspection. Third-party cost data from Houzeo (2026) puts the Delaware statewide average at $350 to $425 for a typical resale property.
How Much Does a Home Inspection Cost in Delaware?
Residential home inspection pricing in Delaware starts at $425 with Preferred Home Inspections for a full single-family evaluation with a same-day digital report. Most buyers also add radon testing ($130) and a termite inspection (starting at $95) to the same visit, completing all three in a single two-to-four-hour site visit.
The table below shows Preferred Home Inspections’ published prices alongside the typical Delaware range from competing local inspectors and third-party sources (Houzeo, 2026; ValueGuard, TMK Home Inspections, as of September 2026).

What Changes the Price of a Delaware Home Inspection?
Four factors drive most price differences on a Delaware home inspection quote: the square footage of the property, the age of the home, the property type (single-family vs. condo or townhome), and site features such as a private well, septic system, or crawl space. Each factor is covered in its own section below.
Does Square Footage Change the Cost?
Square footage is the primary driver of inspection cost at Preferred Home Inspections. Larger homes take more time to walk and generate more detailed reports. A property above Preferred’s size threshold carries a higher base rate than a smaller home in equivalent condition. This is standard across Delaware inspection companies: competing firms charge $450 or more for larger single-family homes. Buyers purchasing properties over 3,000 square feet should request a specific quote by calling 302-475-4437 before booking. For most resale homes in New Castle County, the starting rate of $425 applies.
Do Older Delaware Homes Cost More to Inspect?
Pre-1950 homes in Wilmington, particularly rowhomes and twin properties, typically take longer to inspect than newer construction in Middletown or Smyrna. Older homes may contain knob-and-tube wiring, galvanized supply lines, settled foundations, and original HVAC equipment, each of which requires more documentation time. Cortland Bradley has inspected Wilmington properties built in the 1890s and 1930s, and the inspection report for a century-old rowhome covers significantly more ground than a 2015 townhome build.
The base inspection price at Preferred Home Inspections does not change based on age alone, but buyers purchasing older homes in Newark’s historic core or Wilmington’s tree streets should expect an inspection that runs toward the longer end of the two-to-four-hour range. For context on what those older properties commonly reveal, see the common home inspection findings in Delaware guide.
How Much Is a Condo or Townhome Inspection in Delaware?
A condo or townhome inspection in Delaware costs less than a full single-family inspection because the scope is narrower. HOA-maintained roof, exterior cladding, and shared structural elements fall outside the standard condo inspection scope. The inspector focuses on the unit interior, HVAC, plumbing within the unit, electrical panel, and any accessible crawl space or attic hatch.
Preferred Home Inspections’ condo and townhome pricing is not published as a fixed rate on the site. Contact Cortland Bradley directly at 302-475-4437 for a quote on the specific property. For reference, Delaware condo inspection prices at competing firms run $299 to $375.
Do Wells, Septic Systems, or Crawl Spaces Add to the Cost?
Kent County and Sussex County homes frequently operate on private wells and septic systems rather than public utilities. A standard home inspection at Preferred Home Inspections covers all accessible visible components of the property, but a dedicated well water test or septic pump-and-inspect is typically arranged through a licensed specialist and billed separately. Buyers purchasing in Millsboro, Lewes, or rural Kent County should budget for these add-ons.
Crawl spaces are common throughout New Castle County and are inspected as part of the standard scope at no added fee. Preferred Home Inspections accesses all accessible crawl spaces during the standard inspection to check for moisture intrusion, pest activity, and structural conditions.
What Do Radon and Termite Add-Ons Cost in Delaware?
A radon test in Delaware costs $130 with Preferred Home Inspections. A termite (WDI) inspection starts at $95. Both are available as add-ons to a residential inspection, and combining them in a single visit is the most cost-efficient approach.
How Much Is a Radon Test in Delaware?
A radon test in Delaware costs $130 with Preferred Home Inspections. The test places a continuous electronic monitor in the lowest livable area of the home for a minimum 48-hour period, per EPA and AARST-NRPP protocol. Results are included in the inspection report or delivered separately if ordered as a standalone service.
New Castle County has above-average radon potential compared to the national baseline. The EPA action level is 4.0 pCi/L (EPA, 2024); homes across the Wilmington metro and surrounding suburban areas exceed this threshold at higher rates than the U.S. average. Radon is the second-leading cause of lung cancer in the country (EPA, 2024). Detection before purchase gives buyers the option to negotiate mitigation into the sale. For more background on radon risk in Delaware homes, see the importance of radon testing in Delaware.
How Much Is a Termite (WDI) Inspection in Delaware?
A termite inspection in Delaware starts at $95 with Preferred Home Inspections. The inspection produces an NPMA-33 report, the standardized Wood Destroying Insect form required by FHA and VA lenders for most real estate transactions. The NPMA-33 documents the presence or absence of wood-destroying insects, including termites, carpenter ants, and powder post beetles, and notes any visible structural damage.
FHA and VA lenders typically require a completed NPMA-33 with the loan file. Conventional buyers frequently order one as well, since Delaware’s humid Mid-Atlantic climate supports year-round termite activity, particularly in New Castle County. The report is generally valid for 30 days from the inspection date. Preferred Home Inspections performs WDI inspections statewide. For full detail on termite inspection scope and what the report covers, see the Delaware termite inspection page.
What Does a Standard Home Inspection Include for the Price?
A standard Delaware home inspection covers all major accessible systems and components of the property, following the ASHI Standards of Practice (homeinspector.org). Preferred Home Inspections delivers a same-day Spectora digital report with photos of every significant finding, accessible from any device. The report is typically delivered the same day as the inspection.
Systems covered in a standard inspection include:
- Structure and foundation, including visible basement and crawl space conditions
- Roof covering, flashing, gutters, and attic
- Exterior cladding, grading, and drainage
- Plumbing supply lines, drainage, and water heater
- Electrical panel, wiring, outlets, and fixtures
- Heating and cooling systems, ductwork, and vents
- Insulation and ventilation
- Interior walls, ceilings, floors, and doors
- Built-in appliances
The report identifies conditions that affect safety, habitability, and long-term maintenance. Priority levels help buyers distinguish findings that require immediate action from those that are routine maintenance items. For a walkthrough of report format and what to expect after the inspection, see the Preferred Home Inspections report page.
Who Pays for a Home Inspection in Delaware, and When?
The buyer pays for a home inspection in Delaware. Payment is collected at or before the inspection, not at closing. The cost is not rolled into the mortgage or closing costs. Most buyers pay by credit card or check directly to the inspector on the day of service.
The exception is a pre-listing inspection ordered by a seller. Sellers who commission an inspection before listing pay out of pocket to find and address issues before buyers see the home. A pre-listing inspection reduces the chance of a deal falling apart after the buyer’s inspector finds something unexpected. Preferred Home Inspections performs pre-listing inspections at the same base rates as buyer inspections. For more on how pre-listing inspections work, see the pre-listing inspection page.
Is a Cheaper Home Inspection Worth It?
Price differences between inspectors in Delaware usually reflect time on site, report quality, and inspector qualifications, not a discount on the same service. A $250 inspection and a $425 inspection are not interchangeable. Delaware requires all home inspectors to hold a state license through the Board of Home Inspectors, managed by the Division of Professional Regulation. Checking that license before booking takes about 30 seconds on the state website.
Preferred Home Inspections’ base price reflects a two-to-four-hour on-site inspection by Cortland Bradley, who has personally completed over 10,000 inspections since founding the company in Wilmington in 1994. A shorter inspection from a newer inspector costs less. Missing a roof in poor condition that costs $12,000 to replace, or an HVAC system at end of life, makes the price difference irrelevant.
Before booking on price alone, verify the inspector’s Delaware license status on the Division of Professional Regulation website, confirm ASHI membership, and ask for a sample report. For context on what inspection findings typically cost to repair in Delaware, see the common home inspection findings page.

Does a Home Inspection Cost More in Wilmington, Newark, Dover, or Sussex County?
Preferred Home Inspections charges the same base rate for residential inspections across Delaware, from Wilmington and Newark in New Castle County to Dover in Kent County and Sussex County communities including Lewes, Rehoboth Beach, and Millsboro. New Castle County represents the core service area, and most jobs fall within a 45-minute drive from Preferred’s Wilmington base.
For buyers purchasing in Wilmington’s rowhome neighborhoods, see the Wilmington home inspection page. For New Castle County suburban buyers, see the Newark home inspection page. Sussex County properties, particularly those near Lewes and Rehoboth Beach, frequently include private wells and septic systems not present in New Castle County homes; see the Lewes home inspection page for service details in that area.
How Can You Save on a Delaware Home Inspection Without Cutting Corners?
The most direct way to streamline the inspection process in Delaware is to bundle services in a single visit. Ordering radon testing and a WDI inspection alongside the residential inspection means Preferred Home Inspections handles all three during a single site visit. Contact 302-475-4437 to ask about current bundle pricing before booking.
Booking early in the contingency period also avoids rushed scheduling. Sellers can consider a pre-listing inspection rather than waiting for the buyer’s inspector to surface issues at the worst point in the negotiation. For current homeowners not in a transaction, an annual home maintenance inspection through Preferred Home Inspections catches deterioration before it becomes an expensive repair.
Delaware Home Inspection Cost FAQs
How much is a home inspection for a condo in Delaware?
Condo inspection pricing at Preferred Home Inspections is available by quote based on the specific property; call 302-475-4437 for a rate. The inspection covers the unit interior, HVAC, plumbing within the unit, electrical panel, and any accessible crawl space or attic hatch. HOA-maintained roof, exterior structure, and shared common areas fall outside the scope. Delaware condo inspection prices at competing firms run $299 to $375.
Is a new construction home inspection cheaper?
New construction inspections at Preferred Home Inspections are priced the same as resale home inspections. Newer homes have fewer legacy defects, but fresh construction produces its own category of issues: missed punch-list items, improper grading, HVAC ductwork gaps, and incomplete insulation are common findings on builder-new homes in Delaware. A new construction inspection delivers full value at the standard inspection price.
Can the home inspection fee be paid at closing?
No. Home inspection fees are collected at or before the inspection, not at closing. The cost is not rolled into mortgage financing or closing costs. Preferred Home Inspections collects payment directly from the buyer on the day of service. Most buyers pay by credit card or check.
Is radon testing required when buying a home in Delaware?
Radon testing is not legally required for buyers in Delaware, but it is strongly recommended. The EPA action level is 4.0 pCi/L; homes above that threshold warrant mitigation. New Castle County tests above the EPA action level at above-average rates. Testing costs $130 with Preferred Home Inspections and is easily bundled with the residential inspection in a single visit.
How soon do I get the inspection report after I pay?
Preferred Home Inspections delivers the Spectora digital report the same day as the inspection in most cases. The report includes photos of all noted conditions and is accessible from any device immediately after delivery. Confirm same-day availability when booking at 302-475-4437.
Does a home inspection cost more for a house with a crawl space or basement?
Preferred Home Inspections includes all accessible crawl spaces and basements in the standard inspection at no additional charge. The inspection checks for moisture intrusion, pest activity, insulation gaps, and structural conditions in these areas. Homes with both a basement and a crawl space may take slightly longer to complete, but the base inspection price does not change.
