Questions to Ask a Home Inspector
For home buyers hiring an inspector and walking the house with one. The questions follow the order things happen: before you hire, what the inspection covers and which extra tests to add, during the inspection itself (structure and water, then systems and safety), and after the report arrives. Each has a note on what a good or a worrying answer sounds like, and where the rules differ by state or country the note says to ask how it works there.

The questions
Each question, and why to ask it
Before you hire
Are you licensed or certified to inspect homes here, and how can I check that myself?
Why ask it
Licensing differs from one state or country to the next, and some places have none at all, so ask what is required where the house is. Whatever the credential, look the name up on the issuing body's own website instead of trusting a logo on a business card. Where there is no license, ask about training, exams and which professional association they belong to.
What does your inspection cover, and which written standard do you follow?
Why ask it
Inspectors usually work to a published standard of practice, set by a licensing board or a professional association, which lists what must be looked at and what need not be. Ask for the link and read it before the day. In general it describes a visual check of what can be reached at the visit: structure, roof, exterior, plumbing, electrical, heating and cooling, and interior.
How many homes have you inspected, and how many were like this one in age and type?
Why ask it
The total matters less than the match. Someone who mostly sees new construction will read a ninety-year-old house, a condo or a place on a well and septic tank with less confidence. A strong answer names, unprompted, the two or three things that tend to go wrong in houses like yours.
Can I see a full report you wrote for a similar house?
Why ask it
This is the fastest way to compare inspectors, because the report is what you are buying. Look for photos of each defect, plain descriptions of where it is and why it matters, and a summary that separates the serious from the routine. Pages of boxes checked 'satisfactory' with little writing will not help you negotiate or plan repairs.
Can I come to the inspection and walk through the house with you?
Why ask it
The answer you want is yes, ideally with an invitation to stay for all of it. Seeing a crack or a stain in person while someone explains it tells you more than a photo and a caption will later. If an inspector prefers buyers to stay away, or allows ten minutes at the end, compare them with one who does not.
What do you charge for a house like this, and what is included in that price?
Why ask it
Give the address, size and age so the figure is real, then ask what would raise it: a crawl space, a second building, an older house, extra tests. Fees vary by region and by house, so get two or three quotes for the same scope. The cheapest quote is often the shortest visit, and the saving is small beside the cost of a problem nobody saw.
How long will you spend at the house?
Why ask it
Ask for time on site, separate from writing the report. An ordinary house usually takes a few hours, and longer if it is large, old or has a crawl space. Be wary of anyone fitting four or five inspections into one day, because the last house gets a tired inspector.
What did you do before you became a home inspector?
Why ask it
Many inspectors come from a building trade, engineering or code enforcement, and each background leaves strengths and blind spots. A former roofer will be sharp above the ceiling and may be less sure at the electrical panel. Follow up by asking what they have trained in since, especially on the system that worries you most in this house.
Do you carry insurance for mistakes in the report and for accidents at the property?
Why ask it
The two kinds usually go by the names errors and omissions and general liability. Whether either is required depends on where you are. Ask to see the certificates regardless: reluctance to email a document that takes a minute to find is worth noticing.
Do you do repairs yourself, or get paid by anyone you refer me to?
Why ask it
An inspector who also sells the fix has a reason to find the problem. Some places bar inspectors from repairing homes they have inspected, and others leave it to you to ask. The clean answer is that they inspect only, and that the names they pass on are people they would call for their own house, with no fee coming back.
Who gets the report: only me, or my agent as well?
Why ask it
You are paying, so the usual arrangement is that the report is yours and goes to others only when you say so. Ask it plainly if your agent recommended the inspector, since someone who relies on an agent's referrals can feel pressure not to alarm a buyer. Plenty are blunt regardless, but you should hear them say who they answer to.
Can I read your inspection agreement before the day, and what does it say if you miss something?
Why ask it
These agreements often cap what the inspector owes you, sometimes at the fee you paid, and may set a short window for raising a complaint. How far such limits hold up depends on local law, so ask someone qualified if it worries you. The driveway, with the inspector waiting, is the wrong place to read it for the first time.
How soon can you inspect, and when will I have the written report?
Why ask it
If your offer depends on the inspection you are probably working against a deadline, so ask your agent or attorney exactly when it runs out and what counts as meeting it. You need the report early enough to bring in a specialist and still respond in time. Same day or next day is common, and a week can be too slow when the deadline is short.
Scope and extras
What do buyers assume is included that is not?
Why ask it
Common surprises are the inside of walls, the sewer line under the yard, the chimney flue, pools, wells, septic systems and anything behind stored boxes. Detached garages, sheds and fences may or may not be part of it. Better to hear the list now than to find 'not inspected' in the report after your deadline has passed.
Will you walk the roof and go into the attic and crawl space, and what would stop you?
Why ask it
A steep pitch, wet or fragile roofing, a very low crawl space, standing water or a sealed hatch are fair reasons to stay out. What matters is the fallback: a drone, a camera on a pole, binoculars from a ladder, or a return visit. Anything not entered should be named in the report along with the reason.
Which extra tests do you offer, and which would you order for this house?
Why ask it
Depending on the region and the house these can include radon, wood-destroying insects, mold sampling, well water, septic, lead paint, asbestos and a sewer camera. Each costs extra and some need a separately licensed person. A thoughtful inspector picks two or three for this address and says why, where a salesman offers the whole menu.
Should the sewer line be checked with a camera, and do you do that or know who does?
Why ask it
A standard inspection does not see inside the pipe that runs from the house to the street or tank. Who pays to repair that pipe differs by place, and it is often the owner, which the local water or sewer authority can confirm. If the house is old, the drains are slow or large trees stand near the line, say yes, and keep the video file with the distance mark where any damage shows.
What equipment do you bring beyond a flashlight and a ladder?
Why ask it
A moisture meter, an outlet tester, a gas and carbon monoxide detector and a thermal camera are all common, and each finds things eyes cannot. Tools do not replace judgment, though. Ask what the thermal camera turned up on a recent job that would otherwise have been missed, and you will learn whether it leaves the truck.
Do you run the appliances and fixtures, and which ones?
Why ask it
Some inspectors run the dishwasher through a cycle, light every burner and fill the tubs. Others note only that an appliance is present. Neither can promise it will work next month, but knowing which you are getting tells you whether to test the washer and oven yourself at the final walk-through.
What has to be switched on or cleared before you arrive?
Why ask it
Water, gas and electricity need to be live, pilot lights lit, and the attic hatch, electrical panel and crawl space entrance free of the seller's belongings. In a vacant or winterized house that takes arranging days ahead through the agents. If a utility is off on the day, whole systems go down as 'not tested' and you pay for a second trip.
Do you look into permits for the additions and remodeling, or is that mine to check?
Why ask it
Usually it is yours: inspectors judge the work they can see, and the paper trail sits with the local building department. Ask the inspector which parts of the house look newer than the rest, then ask the department or your agent how permits are looked up there. Unpermitted work is treated differently from place to place, so find out what it would mean for you before the deadline.
Is there anything you cannot check properly at this time of year?
Why ask it
Air conditioning may not be run in cold weather, a roof under snow cannot be seen, and a basement that leaks in spring can look dry in August. A careful inspector lists these limits without being asked. For each one, ask what evidence would show the problem anyway, such as old water lines on a wall or rust at the base of the furnace.
In a condo or townhouse, how far does your inspection go past the walls of the unit?
Why ask it
Roofs, hallways, garages and shared plumbing may belong to the building and fall outside the visit, yet their repair bills can reach you through fees or assessments. Ask what they will at least look at from the common areas. Then ask through your agent which of the association's inspection and reserve documents you can see, since that varies by place.
Structure and water
How many years does this roof have left, and what are you basing that on?
Why ask it
You are after a range and the evidence for it: curling or missing shingles, worn granules, soft spots, patches, the state of the flashing around chimneys and vents. Ask how many layers are on it, since a second layer changes the price of the next roof. An insurer may care about roof age too, so pass the estimate to yours.
Are these cracks ordinary settling, or would you want a structural engineer to look?
Why ask it
Point at each one. Hairline vertical cracks are often shrinkage, and inspectors tend to worry more about wide cracks, stair-step patterns in block or brick, horizontal cracks, and walls that bow or lean. If the word 'engineer' comes up, book one before your deadline, because that is the opinion a seller will take seriously.
Do any of the windows or doors stick, leak or have fogged glass?
Why ask it
Fog between the panes is a failed seal, which costs money and harms nobody. A bedroom window painted shut is a fire exit that does not open, and a door binding in a frame gone out of square is one more thing to show whoever looks at the cracks. Have the rooms named in the report, since 'some windows' is no use to a contractor.
Has water been getting into the basement or crawl space, and is it still?
Why ask it
Look together for white powdery deposits on masonry, tide marks, rust at the foot of metal posts, a musty smell or a dehumidifier humming in the corner. A moisture meter separates an old event from a current one. The source matters most, because cleaning a gutter and installing a drainage system are very different bills.
Does the ground carry water away from the house, and where do the gutters empty?
Why ask it
Walk the outside together for this one. Soil that slopes toward the wall and downspouts that empty beside the foundation are behind a great many wet basements, and both are cheap to correct compared with the damage. Have each spot pointed out so you can deal with them in your first month.
What caused that stain on the ceiling, and is it dry now?
Why ask it
A stain is a record, not a verdict. What matters is what sits above it (a bathroom, a roof valley, an air conditioner's drain pan) and what the moisture meter reads today. One newly painted square on an otherwise older ceiling deserves the same question, plus one to the seller about what was repaired and when.
What did you find in the attic?
Why ask it
A short question with a long answer if the inspector is good: how deep and even the insulation is, stains or daylight on the underside of the roof, bathroom fans that vent into the attic instead of outdoors, signs of animals, and dark patches that suggest poor ventilation. Photos matter here more than anywhere, since you are unlikely to go up there yourself.
Do you see signs of termites, carpenter ants or rot in the wood?
Why ask it
Mud tubes on foundation walls, wood that sounds hollow when tapped, fine sawdust and soft sills are the usual signs. In some regions a separate pest inspection is routine or a lender asks for one, so find out what applies to your purchase. Old damage that was treated is common and manageable, while live insects or structural wood that crumbles calls for a specialist's quote.
Is the deck or balcony attached and supported the way it should be?
Why ask it
Decks are a favorite weekend project, and it shows. The inspector should look at how it is fastened to the house, whether there is flashing where it meets the wall, the posts and footings, and how firmly the railings hold. If the answer is doubtful, keep people off it until a contractor has looked.
Does anything here look like amateur work, or a repair meant to hide something?
Why ask it
Useful in any house and essential in one that was renovated quickly for resale. Inspectors notice new drywall in one corner of a basement, mismatched materials, wiring made from extension cord, plumbing held together with tape. Each is a prompt to ask the seller for the story and the permit, not proof of a problem.
Systems and safety
Is the electrical panel safe, and is the service big enough for how we plan to live here?
Why ask it
Mention what you will add: a car charger, central air, an electric range, a workshop. The inspector should take the cover off and look for scorching, corrosion, doubled-up wires and breakers that do not match the panel. Capacity is a separate matter from safety, and an electrician can price an upgrade before you commit.
Is any of the wiring an older type that electricians or insurers are wary of?
Why ask it
Certain older wiring methods and a few panel models have poor reputations, and some insurers ask about them before offering a policy. Have the inspector write down exactly what was found and how much of the house it serves. Then call an insurer with those exact words before your deadline, because coverage and cost depend on the company and the place.
Do the outlets near water have shock protection, and are there working smoke and carbon monoxide alarms?
Why ask it
Kitchens, bathrooms, garages and outdoor outlets are where protective outlets (GFCI in the United States) are expected in newer work, and older houses often lack them. Rules on alarms are local and sometimes apply when a house is sold, and the inspector should know what this address needs. These are small, cheap jobs, which makes them easy to finish in your first week.
What are the supply pipes and drains made of, and how much life is left in them?
Why ask it
Copper, plastic, galvanized steel, cast iron and lead each age in their own way, and a house often has several from different decades. Ask where the old material remains, especially in runs hidden behind finished walls. If the answer includes a material with a record of failing, a plumber's quote for replacing it belongs in your numbers.
How does the water pressure hold up when several faucets and a shower run at once?
Why ask it
Ask to see it done: a shower upstairs, a sink below, a toilet flushed. A shower that fades with everything running points to narrowed old pipes or a supply problem, and a tub that drains slowly or gurgles hints at the drain line. On a well, ask how the pump and pressure tank behaved during the same test.
How old are the furnace, the air conditioner and the water heater, and how do you know?
Why ask it
The date is usually on the data plate or coded into the serial number, and the inspector can read it for you. Age alone is not a defect, so ask what condition each is in for its years. Write the dates down: they tell you which replacement to save for first.
Does the heating and cooling reach every room, and does the equipment look like it has been serviced?
Why ask it
A thorough inspector checks airflow or heat in each room, not only that the unit starts. Rooms over a garage, additions and top floors are where the gaps show. Service stickers, a clean filter and a tidy burner compartment suggest care, and if all three are missing, ask the seller for records and book your own service visit after you move in.
Are the fireplace and chimney safe to use as they are?
Why ask it
From the hearth and the roof an inspector sees only the two ends of a flue. Cracked crowns, missing caps, loose bricks and heavy soot are visible, and the liner mostly is not. If you intend to light fires, expect to be told to have a chimney sweep look inside with a camera first, and treat that as ordinary caution.
Did you see anything that might contain asbestos, lead paint or mold, and how would I find out for certain?
Why ask it
Inspectors generally cannot confirm these by eye, which is why reports say 'material that may contain'. Confirmation takes a lab sample, and who may take one and what a seller must disclose differ by location. Ask where the suspect material is and whether it is intact, because what to do next turns on its condition and on your renovation plans.
Where are the main shutoffs for water, gas and electricity, and can you show me how each works?
Why ask it
Five minutes that pay for themselves the first time a pipe bursts. Photograph each one and turn the water valve yourself, because a valve that has not moved in years can be seized. The smaller shutoffs at the water heater and under the sinks are worth finding on the same lap.
Is that normal for a house of this age, or a sign of something worse?
Why ask it
Use this every time the inspector pauses over something. It turns a list of defects into context: every older house has worn parts, and you need to know which wear is expected and which is ahead of schedule. An inspector who answers 'it depends' should be able to say what it depends on.
If we moved in tomorrow, what in this house could hurt someone?
Why ask it
This pulls the safety items out from the long tail of small defects. Expect things like a missing handrail, a gas smell, exposed live wiring, a water heater with no relief pipe, or a garage door that does not reverse. Whatever is named goes to the top of your list however the negotiation with the seller ends.
After the report
Which three findings matter most, and why those?
Why ask it
Reports run to dozens of pages and give a loose doorknob the same typeface as a failing roof. Asking for three forces a ranking. Listen to whether the reasons are about safety, about cost, or about damage that grows if left alone, since that tells you how to rank everything else.
What needs fixing before we move in, what within a year, and what can wait?
Why ask it
Three columns turn a frightening document into a plan. Work that is easier in an empty house, such as refinishing floors, rewiring or removing hazardous material, belongs in the first column even when it is not urgent. Add up the first two columns before you close, so the first year's costs are part of the decision.
Roughly what might the larger repairs cost, or who should I ask for a real number?
Why ask it
Many inspectors will not quote, because pricing is a contractor's job and their standards do not ask it of them. A range offered from experience is still useful as a first sketch. For anything large, get a written estimate from a contractor before your deadline, since a seller answers a contractor's letterhead in a way they do not answer a guess.
Which findings need a specialist, and which kind?
Why ask it
The report will say 'further evaluation recommended' in places, so ask which of those the inspector would act on this week. A structural engineer, a roofer, an electrician, a plumber, a heating technician and a pest company each answer a different question. Book the ones tied to large costs first, because their calendars and your deadline rarely agree.
Which of these would you bring to the seller, and which come with owning any house?
Why ask it
Some inspectors will give a view and some will say negotiation is your agent's field, which is fair. Either way, ask them to mark what is a defect and what is routine upkeep. A short request built on safety and costly items tends to land better than the whole report forwarded with a demand, and your agent or attorney can tell you how requests work locally.
What could you not see or test, and how do I get it looked at?
Why ask it
Every report has a list of limits: a locked room, a roof too wet to walk, furniture against a wall, a system that was switched off. Read that list as carefully as the defects. Some inspectors will come back once access is sorted out, so find out what that costs while there is still time to arrange it.
If the seller makes repairs, will you come back to check them, and what do you charge?
Why ask it
A re-inspection is usually a shorter visit at a lower fee. It earns its cost for anything structural, electrical or on the roof, where 'fixed' can mean many things. Ask the seller for invoices from the contractors who did the work and give copies to the inspector beforehand.
What should I keep an eye on over the next few years, and what upkeep does this house need every year?
Why ask it
Not everything in a report is a repair. A hairline crack to measure and date in pencil, a damp corner to check after heavy rain, caulk and gutters to redo each fall: together these are the owner's manual nobody else will write for you. Ask for the two jobs that owners of similar houses skip and regret.
Can I call you after I have read the report, and for how long does that offer stand?
Why ask it
Questions come on the second reading, and again when a contractor disagrees with something. Ask whether follow-up calls are part of the fee. Ask too whether that still holds months later, when you are living in the house and a line in the report finally makes sense.
If someone in your own family were buying this house, what would you tell them?
Why ask it
Do not ask whether you should buy it: most inspectors will decline, rightly, because the price and your appetite for projects are not theirs to judge. This version usually gets an honest reading of the house against others of its kind. 'Typical for its age, with one thing to deal with' is an answer, and so is a long pause.
How to get the most from a home inspection
Practical guidance for the conversation itself
Before the inspection
Choose the inspector yourself
A recommendation from your agent is a fine place to start, but call two or three and compare their sample reports side by side. The report is the product, so the inspector whose sample you would find easiest to act on is usually the one to hire.
Book as soon as your offer is accepted
Where an offer depends on an inspection there is normally a set number of days, and how that period works differs by place. Ask your agent or attorney for the exact date and what you must send by then, and book the inspector the same day so there is room for a specialist afterward.
Send what you know ahead
The listing, the year built, the seller's disclosure if there is one, and anything that worried you at the showing. An inspector who arrives knowing about the stain in the back bedroom starts there instead of finding it in the last ten minutes.
Settle the first two groups by phone or email
Everything under Before you hire and Scope and extras can be asked before the day. That leaves the visit itself for the house: what is in front of you, what it means and what to do about it.
On the day
Be there, or at least be there for the end
The whole visit is best. If you cannot manage it, arrive for the last hour and ask for a walk-through of the main findings, room by room, so that the report is a reminder of things you have already seen.
Let them work, then ask
Inspectors follow a routine so nothing is skipped, and a question at every outlet breaks it. Keep a running list on your phone and ask as each area is finished: the roof and outside, the basement, the mechanical room, the living floors.
Ask to be shown, not told
'Can you show me where' gets you to the crack, the valve or the scorch mark, and you will remember it. Take your own photos with something in the frame for scale, and note which room and which wall.
Keep the seller and the price out of it
If the seller or their agent is in the house, save your reactions for the driveway. What you plan to ask for is a conversation for you and your own agent after the report is in your hands.
Reading the report
Read all of it once, then the summary again
The summary is the inspector's ranking, and the body holds the detail a contractor will need. The section on what was not inspected is easy to skim past and deserves a slow read.
Sort the findings into three piles
Things that could hurt someone, things that cost real money, and ordinary upkeep. Most of a long report lands in the third pile. A house with a thick report and an empty first two piles is a normal house.
Put numbers on the second pile
Call the relevant contractor for each costly item and ask for a written estimate, or at least a range, before your deadline. Two quotes for a roof or a drain line tell you whether you are negotiating over a little or a lot.
Decide what you are asking for
The usual choices are a repair by the seller, a lower price or a credit, accepting the house as it is, or withdrawing. Which of those are open to you, and by when, depends on your contract and local practice, so go through them with your agent or attorney before you reply.
Mistakes that cost buyers
Hiring on price alone
The difference between two quotes is small next to a single missed repair. Compare the sample reports and the time each inspector plans to spend before you compare the fees.
Treating a clean report as a warranty
An inspection is one person's visual check on one day. It lowers the odds of a surprise and cannot remove them, so keep some money aside for the first year whatever the report says.
Asking the inspector whether to buy
They can tell you what condition the house is in. Whether that condition is worth the price to you is a judgment about your budget and your patience, and it is yours to make.
Sending the seller every line
A request that lists forty items, most of them minor, invites a flat no. Lead with the few that involve safety or large sums, attach the estimates, and let the rest go onto your own to-do list.
