A home inspector is often your first real look at a property's condition—and their findings can make or break a deal. Asking the right questions before you hire one ensures you're getting a thorough evaluation, not a rubber stamp. Here's what to dig into before signing that contract.
Are They Properly Certified and Licensed?
Credentials matter. Ask whether the inspector holds certification from ISHI (International Society of Home Inspectors), NAHI (National Association of Home Inspectors), or your state's licensing board. Most states require licensure; some don't, which is a red flag. Request their license number and verify it directly with your state's regulatory body—don't just take their word for it.
Also ask how long they've been inspecting homes. Someone with 5+ years of experience will typically catch issues that a newer inspector might miss, especially in older homes with quirky systems.
What Does Their Inspection Report Look Like?
Reports vary wildly in quality and detail. Ask for a sample report from the inspector before you hire them. You want one that includes:
- Photos of problem areas, not just text descriptions
- Clear categorization of findings (safety issues, major repairs, minor maintenance)
- Specific observations about age, condition, and remaining lifespan of major systems
- Repair cost estimates where relevant
- Recommendations for follow-up by specialists (electrician, structural engineer, etc.)
A bare-bones one-page report is often a sign the inspector isn't thorough. You should expect 20–50 pages depending on the home's size and condition.
How Long Will the Inspection Take?
A proper home inspection typically takes 2–4 hours for a standard single-family home. If an inspector quotes you 1.5 hours or less, they're either rushing or not checking everything. A larger property or older home may take 4–5 hours. Ask what's included in their timeframe—are they testing GFCI outlets? Checking attic insulation? Running water to all fixtures?
Also ask if they test major systems like HVAC, plumbing, and electrical, or if they only visually inspect them. Testing is better.
What's the Cost, and What's Included?
Home inspection costs range from $300 to $700 depending on your region and property size. Larger homes or multi-unit properties run higher. Get a written quote that specifies exactly what's covered. Ask whether they charge extra for:
- Radon testing ($150–$300 if not included)
- Mold testing ($300–$700)
- Termite or pest inspection ($100–$300)
- Septic system evaluation (if applicable, $300–$500)
- Pool or spa inspection ($200–$400)
Some inspectors bundle these; others charge à la carte. Know your total cost upfront.
Will They Attend the Walk-Through?
A good inspector should be willing to walk the property with you or the buyer after submitting their report. This clarifies findings, shows you problem areas in person, and answers questions on the spot. Some inspectors charge an additional fee for this; others include it. It's worth asking for this service—it adds transparency and helps you understand priorities.
Do They Have Liability Insurance?
Ask to see proof of E&O (errors and omissions) insurance. This protects you if the inspector misses something significant that later costs money to fix. A reputable inspector carries coverage of at least $250,000–$1,000,000.
Are They Independent or Part of a Larger Company?
Independent inspectors and those working for established firms both have pros and cons. Larger companies may have standardized processes and oversight; solo inspectors offer flexibility and direct communication. Neither is inherently better, but knowing the structure helps you understand who you're working with and who to contact if issues arise.
Can They Provide References?
Ask for contact information from recent clients (preferably within the last 6 months). Real estate agents, title companies, and buyers can tell you whether the inspector was thorough, professional, and easy to work with. If they won't provide references, that's a warning sign.
You can also check Google reviews, Yelp, and Better Business Bureau ratings. Look for consistent feedback about thoroughness and professionalism.
Frequently Asked Questions
Q: Can I be present during the inspection? Yes, and you should be. Being there lets you see issues firsthand, ask questions, and get clarity on findings immediately rather than waiting for the report.
Q: How soon will I get the report after the inspection? Most inspectors deliver reports within 24–48 hours. Some offer same-day digital delivery for a fee. Confirm the timeline before you book.
Q: What if the inspector finds major problems? Ask in advance whether they recommend follow-up inspections by specialists (like structural engineers or electricians). A good inspector will tell you when something is beyond general home inspection scope.
