Things to Ask a Home Inspector Before You Buy

A home inspection can generate dozens of observations, but not every item carries the same weight. Before hiring an inspector, understand what the inspection covers, what it does not cover, how findings are documented, and how much time the inspector will spend at the property. During and after the inspection, focus on safety, major systems, water, structure, roof, electrical, plumbing, HVAC, and expensive uncertainties rather than cosmetic defects.

Inspection standards, licensing, certifications, insurance requirements, and legal responsibilities vary by location. A general home inspection also does not replace every specialist evaluation. Depending on the property, you may need separate expertise for septic, sewer, well, chimney, pests, pools, structural concerns, environmental hazards, or other systems.

Things to Ask Before Hiring the Inspector

Choose the inspector based on qualifications, thoroughness, scope, communication, and independence rather than simply the lowest fee or fastest availability.

Ask how the inspector works and whether you can attend.

Are you licensed where required?
What training or certification do you have?
How long have you been inspecting homes?
How many inspections do you perform in a typical week?
Do you carry errors-and-omissions or professional liability insurance where appropriate?
Can I see a sample inspection report?
How long does a typical inspection take?
Can I attend the inspection?
How soon will I receive the report?
Can I call you with questions after reading it?
Do you have any business relationship with the seller, agent, or repair companies?

Things to Ask About What the Inspection Includes

A general inspection is visual and limited by access. Ask what systems are normally examined and what is excluded so you do not assume an inspector is testing something outside the service.

If a property has special features, mention them before booking.

Do you inspect the roof?
Do you enter the attic?
Do you inspect crawlspaces?
Do you inspect electrical panels?
Do you inspect plumbing fixtures and visible piping?
Do you operate heating and cooling equipment?
Do you inspect foundations and visible structural components?
Do you inspect garages and attached structures?
Do you inspect fireplaces or chimneys?
Do you inspect appliances?
What is specifically excluded from the standard inspection?
What additional services do you offer?

Things to Ask About the Roof

Roof replacement can be one of the larger homeownership expenses, so understand approximate age, visible condition, flashing, drainage, signs of leakage, and any areas the inspector could not access.

An inspector may not be able to predict exact remaining life. Ask what evidence supports the condition assessment.

Were you able to walk the roof?
If not, how was it inspected?
What roofing material is installed?
What condition is it in?
Do you see signs of active or previous leaks?
What is the condition of flashing?
Are gutters and downspouts directing water appropriately?
Do you see damaged or missing roofing?
Is roof ventilation visible and apparently adequate?
Is there anything here that deserves a roofer's evaluation?

Things to Ask About the Foundation and Structure

Cracks, settlement, movement, moisture, framing alterations, and sagging can range from ordinary to significant. Ask the inspector to distinguish cosmetic observations from conditions that deserve specialist review.

If the inspector recommends a structural engineer or foundation specialist, ask what specific evidence prompted that recommendation.

Do you see signs of foundation movement?
Which cracks concern you and which look minor?
Do floors appear noticeably out of level?
Do doors or windows suggest movement?
Do you see framing that was cut or altered?
Are there signs of water affecting structural components?
Do you see rot or insect damage?
What structural area could not be inspected?
Would you recommend a structural engineer for anything you observed?

Things to Ask About Water and Moisture

Water causes many expensive home problems. Ask about grading, drainage, basement or crawlspace moisture, roof leaks, plumbing leaks, staining, ventilation, and any evidence of repeated water entry.

A dry day does not prove a basement never leaks. Look for signs of past moisture and ask what the inspector can and cannot conclude.

Do you see signs of current moisture?
Do you see signs of previous water entry?
Is exterior grading directing water away from the house?
Where do downspouts discharge?
Is there a sump pump?
Did you test it where appropriate?
Do you see staining or efflorescence in the basement or crawlspace?
Are bathroom and kitchen exhaust fans vented appropriately?
Do you see signs of plumbing leaks?
What area is most vulnerable to water problems?

Things to Ask About Exterior Drainage and Site Conditions

The lot around a house influences water, foundation performance, basement moisture, retaining walls, driveways, and exterior maintenance. Ask what the inspector can observe about drainage and site conditions.

Some concerns may require landscaping, drainage, geotechnical, structural, or other specialist evaluation rather than a general home inspector.

Does the ground slope toward or away from the house?
Do you see areas where water may collect?
Are retaining walls showing movement?
Are exterior stairs and railings secure?
Do driveways or walks direct water toward the foundation?
Are large trees affecting the roof, drainage, or visible structure?
Is there anything outside that deserves specialist review?

Things to Ask About Electrical Systems

The inspection can identify visible safety concerns and system characteristics, but it is not the same as a full electrical evaluation by an electrician.

Ask about the service, panel, grounding, visible wiring, outlets, and any condition that should be evaluated further.

What is the electrical service size?
What type and approximate age is the panel?
Do you see any panel concerns?
Do you see evidence of amateur or unsafe wiring?
Are GFCI or other protective devices present where expected?
Do you see ungrounded or older wiring?
Are there signs of overheating?
Is the panel crowded or lacking capacity?
What electrical issue deserves the fastest follow-up?
Should an electrician evaluate anything before closing?

Things to Ask About Plumbing

Ask about visible supply and drain materials, water pressure, leaks, water heater, shutoffs, fixtures, and any evidence that piping is near the end of its expected service life.

For older homes, sewer lines may deserve a separate camera inspection because the main line is generally outside the scope of a standard visual inspection.

What visible supply piping materials are present?
What visible drain materials are present?
Do you see active leaks?
How is water pressure?
What is the age and condition of the water heater?
Where is the main water shutoff?
Do fixtures drain normally?
Do you see signs of previous plumbing repairs?
Would you recommend a sewer-scope inspection?
Is there anything a plumber should evaluate before closing?

Things to Ask About Heating and Cooling

HVAC replacement can be expensive, so ask about system age, operation during the inspection, visible maintenance condition, distribution, filters, and anything that could not be tested because of weather.

An inspector can observe operation but may not perform the same diagnostic testing as an HVAC technician.

What type of heating and cooling systems are installed?
What are their approximate ages?
Did they operate normally during the inspection?
Were any systems not tested because of weather?
Do you see signs of poor maintenance?
What is the condition of visible ductwork?
Where are the filters?
Do you see evidence of condensation or drainage problems?
Would an HVAC technician's evaluation be useful before closing?

Things to Ask About the Attic and Insulation

The attic can reveal roof leaks, ventilation, insulation, wiring, framing, exhaust-duct issues, and previous alterations.

Ask what the inspector could see and whether access was limited.

Were you able to enter the attic?
Do you see signs of roof leakage?
How much insulation is present?
Do you see ventilation concerns?
Are bathroom or kitchen exhaust ducts vented outside?
Do you see unusual framing modifications?
Are there signs of pests?
Do you see electrical concerns?
What part of the attic was inaccessible?

Things to Ask About Expensive or Urgent Items

The final report may contain a long list. Ask the inspector to help distinguish immediate safety issues, expensive near-term items, routine maintenance, and cosmetic observations.

The inspector should not decide what you negotiate with the seller. That is a purchase decision. But the inspector can help you understand the significance of the condition observed.

What are the three most important findings?
Which issues are safety concerns?
Which issues could cause significant damage if ignored?
Which systems appear near the end of their service life?
Which findings could be expensive?
Which findings are mostly maintenance?
Which findings are cosmetic?
What specialist inspections would you prioritize?
What should I understand before my inspection contingency expires?

Things to Ask After Reading the Report

Read the full report rather than only the summary. Photographs and descriptions provide context that a red flag list cannot.

Call the inspector with questions about wording you do not understand. A report may intentionally use cautious language because inspectors cannot see inside walls or predict future failures.

Which finding did I misunderstand?
What observation deserves a specialist rather than a general contractor?
Which issue should be corrected before occupancy?
What maintenance should begin immediately after purchase?
Which area could not be inspected fully?
What uncertainty remains even after the inspection?
If this were your own house, what would you investigate further before buying?

Use the inspection to understand the house, not to create a perfect-house checklist.

Every home has defects. The useful question is which defects affect safety, cost, function, water control, or your willingness to own the property.

Things to Ask About Windows, Doors, and the Building Envelope

Windows, exterior doors, siding, trim, caulking, and penetrations help keep water and weather outside. Problems here may be maintenance items or signs of a larger moisture issue.

Ask whether the inspector observed failed seals, rot, difficult operation, damaged flashing, or areas where exterior materials are deteriorating. Replacement cost can be substantial when many windows or sections of cladding are involved.

Do windows open, close, and lock normally?
Do you see failed insulated-glass seals?
Is there rot around windows or doors?
Do exterior doors seal and latch properly?
What is the condition of visible siding or cladding?
Do you see gaps or failed sealant around penetrations?
Are there areas where water could enter behind exterior materials?
What exterior maintenance should be prioritized?

Frequently Asked Questions

Should I attend the home inspection?

If possible and permitted, attending at least part of the inspection can help you understand systems, maintenance, shutoffs, and the significance of findings. Avoid distracting the inspector from the work.

What does a home inspector not check?

Scope varies, but standard inspections may exclude concealed conditions and specialized systems such as sewer lines, septic, wells, pests, environmental hazards, pools, chimneys, or engineering analysis unless separately included.

Should I get specialist inspections too?

Sometimes. The property, age, location, and general inspector's findings may justify specialists such as a structural engineer, roofer, electrician, plumber, HVAC technician, sewer inspector, pest professional, or other qualified expert.
