15 Questions to Ask Your Home Inspector (Before, During, and After)
Get far more from your home inspection by asking the right questions. Exactly what to ask before you hire, what to ask on-site, and what to clarify in the report — so you walk away with a maintenance plan, not just a PDF.
A home inspection is one of the smartest few hundred dollars you'll spend in the entire purchase — but most buyers treat it like a pass/fail test and walk away with a PDF they never open again. That's a waste. The inspector standing in your future home for three hours is the most knowledgeable person you'll have access to about the actual house you're buying. The difference between an average inspection and a genuinely useful one is almost entirely in the questions you ask.
This guide gives you 15 of them, grouped by when to ask: five to vet the inspector before you hire, six to ask on-site during the walkthrough, and four to clarify once you have the report. We've also included what a standard inspection legally doesn't cover, realistic costs, and how to turn the whole thing into your first maintenance plan.
One mindset shift before we start: an inspector reports the condition of the home at the time of inspection. They do not guarantee how long anything will last, and they aren't there to verify code compliance. Their job is to describe what they see and explain what it means — so your questions should pull out that expertise, not ask for guarantees no honest inspector can give.
Before you hire: 5 questions to vet the inspector
You're not just buying an inspection — you're buying this inspector's judgment. Standards vary wildly, and in many U.S. states the profession is lightly regulated or not licensed at all. These five questions separate a thorough professional from someone rubber-stamping a sale.
1. Are you licensed and certified — and with which association?
Licensing requirements differ by state; some require an exam and continuing education, others nothing at all. Independent of state rules, membership in a recognized body — the American Society of Home Inspectors (ASHI) or InterNACHI — signals training, a code of ethics, and ongoing education. Ask for their certification number and what continuing education they've done recently.
2. How long have you been inspecting, and how many inspections have you done?
Experience compounds in this trade. An inspector who has walked thousands of homes recognizes patterns — the telltale sag, the rust bloom, the patch hiding a leak — that a newcomer misses. Years in business and total inspection count both matter; someone five years in who inspects part-time has seen far less than a full-timer.
3. Can I see a sample report?
This is the single most revealing question, and many buyers skip it. A sample report shows you exactly what you'll receive: Is it a thorough, photo-rich document with a clear summary of priorities? Or a thin checklist with boilerplate? You want descriptive findings, photos of each issue, and a prioritized summary you can actually act on — not a wall of "satisfactory / unsatisfactory" boxes.
4. What does your inspection include — and what's not covered?
A standard inspection is a limited, non-invasive, visual examination of accessible areas. A good inspector will tell you plainly where the boundaries are and recommend specialists where needed. This question also surfaces opportunities to add coverage (sewer scope, radon, thermal imaging) before they arrive. See the full out-of-scope list below — it's longer than most buyers expect.
5. Do you carry errors-and-omissions and liability insurance?
A professional inspector carries errors-and-omissions (E&O) and general liability coverage. It's both a professionalism signal and your recourse if something significant was missed through negligence. A confident, established inspector won't bristle at this question.
Green flags in an inspector
Signs you've found a good one
- ASHI or InterNACHI certified, with a number you can verify
- Hands you a detailed sample report without hesitation
- Welcomes you to attend and follow along
- Carries E&O and liability insurance
- Explains what's outside their scope and recommends specialists
- Gives an honest time estimate (2–4 hours for a typical home)
Red flags in an inspector
Keep looking
- Quotes a suspiciously fast, suspiciously cheap inspection
- Won't share a sample report or references
- Discourages you from attending
- Was the only name your listing agent would give you
- Vague about license, certification, or insurance
- Offers to do repairs on the home they're inspecting (a conflict of interest)
A note on agent referrals: a good agent refers good inspectors — but their incentive is to close the deal. Some states have restricted listing agents from steering buyers to specific inspectors precisely because of this conflict. Use a referral as a starting point, then verify the inspector yourself.
During the inspection: 6 questions to ask on-site
Yes, you should attend. Inspectors generally recommend buyers come along, and it's the best few hours you'll spend understanding your future home. A photo in a report is abstract; standing in front of the cracked heat exchanger or the corroded shutoff while an expert explains it is what actually sticks. These six questions make the most of that time.
6. Can I follow you through the inspection?
Ask up front and stay close (without crowding). As you go, you'll learn the house the way an owner needs to — where things are, how they work, and what "normal wear" looks like versus a real problem. This walkthrough quietly becomes your first to-do list.
7. How old is each major system, and how much life is left?
This is the most valuable question in the entire inspection, and it's the one that feeds directly into your maintenance plan. For the roof, HVAC, water heater, electrical panel, and major appliances, ask the inspector to read the age off the data plate and estimate remaining service life. A 22-year-old furnace and a 3-year-old furnace are both "functional" on inspection day — but one is a budget item you need to plan for now.
| System | Typical service life | Why the age matters |
|---|---|---|
| Roof (asphalt shingle) | 20–25 years | Replacement is a five-figure expense — know how close it is |
| Furnace / HVAC | 15–20 years | Efficiency and safety both decline near end of life |
| Water heater (tank) | 8–12 years | A failed tank can flood a finished space |
| Electrical panel | 25–40 years | Old or recalled panels are a safety and insurance issue |
| Major appliances | 10–15 years | Plan replacements before they fail mid-use |
8. Is this a defect, or routine maintenance?
Have the inspector label each finding. A defect is something installed wrong, broken, unsafe, or worn out — potentially worth negotiating. Routine maintenance is upkeep every home needs: dirty filters, missing caulk, clogged gutters, a water heater due for a flush. Confusing the two is how buyers either panic over nothing or try to renegotiate items a seller will rightly refuse.
9. Is this a safety issue, a now problem, or a later problem?
Not every finding carries equal weight. Ask the inspector to triage:
| Priority | What it means | Examples |
|---|---|---|
| Safety | Fix before or immediately after move-in | Missing GFCI protection, gas leaks, no smoke/CO alarms, exposed wiring |
| Now | Material defect affecting the deal | Active roof leak, failed water heater, foundation movement |
| Soon / budget | Plan and save for it | Aging HVAC, roof near end of life, deferred maintenance catching up |
| Monitor | Watch, no action yet | A hairline crack, a slightly damp area to re-check after rain |
10. Where are the main shutoffs, and how do they work?
Before you leave, have the inspector physically show you the main water shutoff, the gas shutoff, and the electrical panel — and how to operate each. New owners who can't find their water shutoff during a burst-pipe emergency lose thousands. This one question can save your floors. (It's also the first task we put at the top of every plan: what to do in your first 30 days.)
11. What would you watch or budget for over the next 1–5 years?
Inspectors see the future of houses for a living. Beyond today's defects, ask what they'd keep an eye on or set money aside for. This forward-looking answer is pure gold for budgeting — it's the difference between being blindsided and having a plan. Pair it with our guide on whether to repair or replace aging systems.
After the inspection: 4 questions about the report
The report usually lands within 24 hours. Don't just skim the summary and file it — these four questions extract the rest of the value.
12. Can you walk me through the summary and what matters most?
A good report has a prioritized summary, but a five-minute call to hear the inspector's emphasis is invaluable. Which three things would they fix first? What looked worse on paper than it is in person — and vice versa? Tone and emphasis don't always survive into a written bullet.
13. Which findings need a specialist?
General inspectors flag concerns but often can't render a professional opinion on them — structural questions, in particular, may legally require a licensed engineer or architect in some states. Ask which items warrant a follow-up from a structural engineer, licensed electrician, roofer, or HVAC tech before you finalize negotiations, so you're pricing real estimates rather than guesses.
14. What additional inspections do you recommend for this home?
Based on what they saw, which specialty inspections are worth ordering? Common add-ons, priced separately:
| Task | How often | DIY cost | Pro cost | Prevents |
|---|---|---|---|---|
| Standard single-family inspection | Once, at purchase | — | $300–$500 | The five-figure surprises that sink new owners |
| Sewer scope (camera) | As needed | — | $150–$300 | A collapsed or root-clogged main line |
| Radon test | As needed | $15–$30 kit | $150–$250 | Long-term health exposure |
| Wood-destroying organism / termite | As needed | — | $75–$150 | Active infestation and structural damage |
| Mold / air quality | If moisture noted | — | $300–$600 | Hidden moisture and remediation bills |
| Pool & spa inspection | If equipped | — | $150–$300 | Costly equipment and safety failures |
15. Can I call you with questions after I've read it?
A professional will say yes. Once you've read the full report, you'll have specific questions — and a quick conversation now prevents misreading a finding and either overreacting or ignoring something real.
What a standard inspection does not cover
This is where buyers get burned: assuming the inspection caught everything. It didn't — and it's not supposed to. A general inspection is limited, non-invasive, and visual, covering only accessible areas. The following are typically outside a standard inspection unless you specifically order them as separate services:
| Out of scope | Why | What to do instead |
|---|---|---|
| Anything behind walls / underground | Non-invasive, visual only | Order a sewer scope; ask about galvanized or lead service lines |
| Code & permit compliance | It's a condition inspection, not a code inspection | Check permit history with the municipality |
| Surveys, boundaries, easements | Not a survey | Order a land survey separately |
| Septic systems & wells | Specialized equipment and licensing | Hire a septic / well specialist |
| Radon, mold, pests | Exceed the general standard of practice | Order as add-on inspections |
| Pools, spas, sprinklers | Outside the standard scope | Add an ancillary inspection if equipped |
| Future life expectancy | They report condition, not guarantees | Use system ages to budget yourself |
If the listing is an older or historic home, pay special attention to the things a visual inspection can only hint at: knob-and-tube or aluminum wiring, buried plumbing, and original grading and flashing. Our guide on maintaining an older home covers what to watch for, and red flags when buying a house covers the deal-breakers.
Turn the report into a maintenance plan, not a filed-away PDF
Here's the part almost everyone misses. The inspection report is, functionally, a complete inventory of your home's systems and their ages — which is exactly the input a maintenance schedule needs. The inspector hands you the raw material; most buyers just never use it.
Do this instead, in your first week:
- Pull out every system age the inspector noted — roof, HVAC, water heater, panel, appliances.
- List the "monitor" and "budget soon" items as future to-dos with rough dates.
- Record the shutoff locations and model/serial numbers in a home inventory.
- Convert it all into a recurring schedule so the flush, the filter, the roof check, and the gutter clean actually happen on time.
That last step is the whole game. A report tells you the condition on inspection day; a schedule keeps it that way. If you'd rather not build the spreadsheet by hand, that's exactly what we do — see your first 30 days as a homeowner and the first-time homeowner maintenance guide for the full handoff from "just bought" to "on top of it."
