Best Home Inspectors in New Hampshire 2026

A home inspection in New Hampshire carries more weight than in many other states. The Granite State’s housing stock is old — roughly 35% of homes predate 1960 — and the climate puts every building system under extreme stress. Ice dams, frost heave, heating system failures, radon, and water intrusion are all common findings that can cost buyers thousands or tens of thousands of dollars if missed during the inspection. New Hampshire licenses home inspectors through the Office of Professional Licensure and Certification (OPLC), requiring 160 hours of approved education, a national exam, supervised inspections, and continuing education. That baseline helps, but the quality gap between a thorough inspector and a surface-level one is enormous. We evaluated NH inspectors based on credentials, report quality, client reviews, thoroughness, and specialty knowledge relevant to New England homes. These are the best home inspectors in New Hampshire for 2026 — the ones who’ll find what others miss before you sign on the dotted line.

1. Pinnacle Home Inspections — Greg Laramie, Southern NH

Greg Laramie has performed over 4,500 inspections across southern New Hampshire in his 14-year career and holds the InterNACHI Certified Master Inspector designation — the highest credential in the field. His inspections are notably thorough, averaging 3.5-4 hours for a standard single-family home versus the industry standard of 2-3 hours. Laramie’s reports include thermal imaging (infrared) at no extra charge, which reveals hidden moisture intrusion, insulation gaps, and electrical hot spots that visual inspection alone can’t detect. His background as a former building contractor gives him an eye for structural issues that purely trained inspectors sometimes miss. Clients consistently praise the detail of his reports, which include annotated photos, prioritized findings, and estimated repair costs.

With 11 years of inspections and over 3,200 completed, he’s seen every version of the old-house surprises that Portsmouth, Dover, and Exeter properties deliver. Marquis holds the NH Licensed Inspector credential plus radon measurement and WDI (wood-destroying insect) certifications, letting him perform a comprehensive evaluation in a single visit rather than requiring multiple specialists. His reports are digital with clickable photos and a summary page that separates safety issues from maintenance items — a format that real estate agents and buyers both appreciate for clarity during negotiations.

3. Granite Inspection Services — Mike Sullivan, Statewide

Granite Inspection Services covers more territory than any other firm on this list, with inspectors serving from the Massachusetts border to the Lakes Region. Founder Mike Sullivan built the company on consistency — every inspector follows an identical 450-point checklist, and all reports use the same format with color-coded severity ratings. Sullivan personally trains and mentors his team, and the company’s quality control includes random ride-alongs and report audits. The firm completes roughly 1,800 inspections annually, making it the largest inspection company in the state. Their scale means same-week availability is almost always possible, which matters in New Hampshire’s fast-moving market where inspection contingency periods are often just 7-10 days.

4. White Mountain Home Inspections — Tom Bradley, North Country/Lakes Region

Tom Bradley is the inspector to call for properties in the Lakes Region and White Mountains, where seasonal homes, mountain properties, and lakefront buildings present unique challenges. He understands the issues specific to vacation properties — winterization failures, ice dam damage from intermittent heating, seasonal water system problems, and the higher snow loads that mountain properties endure. Bradley holds a structural engineering technology degree and applies that knowledge to foundation and framing assessments, which is particularly valuable for older ski chalets and lake houses built to less rigorous standards. Use our AI real estate tools for detailed numbers. His inspection reports include a seasonal maintenance calendar specific to the property — a touch that’s especially useful for out-of-state buyers purchasing vacation homes.

5. Tristate Property Inspections — Karen Walsh, Nashua/Border Region

Karen Walsh carved a niche serving the Nashua-area market where Massachusetts buyers cross the border and often face unfamiliar inspection issues — septic systems (many MA buyers are used to municipal sewer), well water, heating oil systems, and New Hampshire’s particular building code nuances. Walsh takes extra time to educate first-time NH buyers on systems they’ve never owned before, walking clients through the well pump, the septic tank access, and the oil furnace during the inspection. She completes about 280 inspections per year and maintains a response rate that clients rave about — she answers follow-up questions by phone for months after the inspection at no charge. Her reports include a “New Hampshire Homeowner Guide” section with maintenance schedules specific to the property’s systems.

How We Ranked These Inspectors

What a New Hampshire Home Inspection Covers

NH standards of practice require licensed inspectors to evaluate the following systems and components during a standard home inspection:

Additional Testing You Should Consider

• Radon testing ($125-$200): New Hampshire has the second-highest average indoor radon levels in the country. About 40% of NH homes test above the EPA’s 4.0 pCi/L action level. Radon testing should be considered mandatory for any home purchase in the state. Mitigation, if needed, costs $800-$1,500.
• Well water testing ($150-$350): Required for FHA/VA loans. Tests for bacteria, nitrates, arsenic (elevated in many NH wells), lead, and other contaminants. Private wells serve about 40% of NH homes.
• Septic inspection ($350-$600): Separate from the home inspection and performed by a licensed septic professional. Includes tank condition, sludge levels, and leach field assessment.
• Wood-destroying insect inspection ($75-$175): Checks for carpenter ants, termites (southern NH), powder post beetles, and carpenter bees. Required for VA loans.
• Lead paint testing ($250-$500): Important for any pre-1978 home, especially with young children. Not routinely included in standard inspections.
• Chimney inspection ($200-$400): Level 2 chimney inspection with video camera, recommended for any home with a fireplace or woodstove you plan to use.

Factor these testing costs into your closing cost budget — they’re separate from the home inspection fee but equally important.

How to Use Inspection Results in Negotiations

In New Hampshire’s competitive market, how you handle inspection findings can make or break a deal. The standard approach:

• Safety issues: Electrical hazards, structural defects, active water intrusion, radon above 4.0 pCi/L, and failed septic systems are legitimate repair requests that most sellers will address or credit.
• Major systems: A roof near end of life, an aging furnace, or outdated electrical panel are reasonable negotiation points. Request repair credits rather than requiring the seller to do the work — you’ll control the quality of the fix.
• Maintenance items: Peeling paint, caulking needs, and minor cosmetic issues are not typically negotiation items. Requesting credits for routine maintenance makes you look like a difficult buyer.
• Use our net proceeds calculator to model how repair credits affect the seller’s bottom line when negotiating.

Frequently Asked Questions

How much does a home inspection cost in New Hampshire?

Standard home inspections in New Hampshire run $400-$650 depending on the home’s size, age, and location. Larger homes (3,000+ sq ft) and older homes (pre-1950) cost more due to additional time required. Seacoast properties tend toward the higher end of the range. Add-on services like radon testing ($125-$200), well water testing ($150-$350), and WDI inspection ($75-$175) are additional. A comprehensive inspection with all testing can total $700-$1,200 — a tiny fraction of your purchase price that can save you from $10,000+ surprises.

Are home inspections required in New Hampshire?

Not legally required, but strongly recommended for every purchase and expected by most lenders. In competitive situations, some buyers waive the inspection contingency to strengthen their offer — this is risky, especially with older New Hampshire homes where hidden issues are common. A better approach is to shorten the inspection period (7 days instead of 14) and schedule the inspection immediately after offer acceptance. Never skip the inspection on a pre-1970 home.

How long does a home inspection take?

A thorough inspection of a standard single-family home takes 2.5-4 hours on site, depending on the home’s size, age, and complexity. Older homes, larger properties, and homes with multiple systems (well, septic, oil heat) take longer. Plan to attend the entire inspection — the walkthrough at the end where the inspector explains findings is the most valuable part. Rushed inspections (under 2 hours for a full house) should raise concern about thoroughness.

What should I do if the inspection reveals major problems?

Major findings (structural issues, failed septic, extensive water damage, hazardous wiring) give you three options: negotiate a price reduction or repair credit, require the seller to fix the issue before closing, or walk away using your inspection contingency. The best approach depends on the severity, the cost to fix, and how much you want the property. Your agent and inspector can help you prioritize which issues are deal-breakers versus negotiation points. Get contractor estimates for major repairs before making your request — specific numbers carry more weight than vague concerns.

Should I get a radon test when buying in New Hampshire?

Yes — consider it mandatory. New Hampshire has the second-highest average indoor radon levels in the country, and roughly 40% of homes test above the EPA’s 4.0 pCi/L action level. Radon is a colorless, odorless gas that causes lung cancer with long-term exposure. Testing costs $125-$200 and takes 48 hours. If levels are elevated, a radon mitigation system costs $800-$1,500 and reduces levels by 90-99%. This is a solvable problem — the key is testing before you buy so you can negotiate mitigation as part of the sale. Our home buying guide covers the full inspection process.

Can I attend the home inspection?

Absolutely — and you should. New Hampshire inspectors encourage buyer attendance, especially for the final walkthrough portion where they explain findings, demonstrate systems, and answer questions. Being present lets you see issues firsthand, ask about severity, and get informal advice about maintenance priorities. Use our home maintenance calculator for detailed numbers. Allow 3-4 hours in your schedule. Bring a notepad and comfortable shoes — you’ll be walking through attics, basements, and around the exterior.

How do I verify a home inspector’s license in New Hampshire?

The NH Office of Professional Licensure and Certification (OPLC) maintains a public database of licensed home inspectors. You can search by name or license number at their website. Verify that the license is current (not expired or suspended), and check for any disciplinary actions. Use our rent affordability calculator for detailed numbers. Beyond the state license, look for national certifications from ASHI (American Society of Home Inspectors) or InterNACHI (International Association of Certified Home Inspectors) — these organizations require additional training and adherence to higher standards of practice.
