How to Evaluate a Home Inspector Before You Hire

Your real estate agent might recommend a home inspector. A friend might recommend a different one. Google shows a dozen more. How do you know who to trust with the most important evaluation of the biggest purchase of your life?

After 20-plus years inspecting homes throughout the Philadelphia suburbs — Montgomery, Bucks, Chester, Delaware, and Camden Counties — I've seen what separates a good inspection from a costly mistake. Here are the seven questions that matter most.

1. Who Will Actually Perform My Inspection?

This is the single most important question you can ask, and most people never think to ask it.

Large inspection companies operate on a dispatch model. You research the company, read the owner's bio, and feel confident — then a different person shows up on inspection day. That person might have years of experience, or they might have months. You often have no way of knowing until they arrive.

With an owner-operated inspection business, the person whose name and reputation are on the line is the same person walking through your home. That means consistent quality, direct accountability, and one point of contact from your first phone call through your last question about the report.

When you call to schedule, ask directly: "Will you personally be performing my inspection?" The answer tells you a lot about the kind of experience you're going to have.

2. What Certifications and Licenses Do You Hold?

In Pennsylvania, home inspectors are required to hold a state license. But licensing is a floor, not a ceiling. The inspectors who invest in advanced certifications are signaling something about how seriously they take the profession.

The two most respected industry certifications are InterNACHI (International Association of Certified Home Inspectors) and ASHI (American Society of Home Inspectors). Both require adherence to a comprehensive standard of practice, ongoing education, and a code of ethics. InterNACHI's CPI designation — Certified Professional Inspector — is widely regarded as the top credential in the field.

If your inspector also performs mold testing, ask whether they hold a separate certification for that. PRO-LAB certification, for example, means the inspector has been trained in proper sampling protocols and works with an accredited lab for analysis. Mold testing performed by someone without proper training can produce unreliable results — and unreliable results can cost you thousands in unnecessary remediation or, worse, missed contamination.

3. Will You Physically Inspect the Roof?

This question might seem oddly specific, but it reveals a lot about an inspector's thoroughness.

A roof is one of the most expensive systems in a home. Replacing one can cost $10,000 to $25,000 or more depending on the size and materials. A physical roof inspection — actually walking the roof when it's safe to do so — catches problems that are invisible from the ground: soft spots, flashing gaps, early deterioration around penetrations, nail pops, and granule loss that indicates age.

Some inspectors have moved to drone-only or ground-level visual assessments as their standard practice. While drones have legitimate uses (steep pitches, wet conditions, structural concerns), using them as a default substitute for hands-on inspection means you're getting less information about one of the home's most critical and expensive components.

Ask: "Do you walk roofs as part of your standard inspection?" The answer should be yes, with exceptions only for genuine safety concerns.

4. How Long Will the Inspection Take?

A thorough inspection of a typical single-family home takes two to four hours, depending on the home's size, age, and condition. Larger homes, older homes, and homes with additional structures (detached garages, finished basements, additions) take longer.

If an inspector is consistently finishing in under 90 minutes, that's a red flag. It likely means systems are being skipped, crawl spaces aren't being entered, or the inspection is being performed as a visual walkthrough rather than a hands-on evaluation.

Volume-driven inspection companies sometimes schedule inspectors for multiple jobs per day. The pressure to stay on schedule can mean shortcuts — and shortcuts mean missed findings that show up as expensive surprises after you close.

A good inspector takes the time the home requires. No more, no less.

5. Can I Be Present During the Inspection?

The answer should always be yes — and ideally, it should be an enthusiastic yes.

The best inspectors don't just produce a report. They use the inspection as an opportunity to educate you about the home you're buying. They walk you through each system, explain what they're seeing, point out maintenance items, and give you context for the findings that will appear in the written report.

An inspector who prefers to work alone, starts before you arrive, or discourages your presence during the inspection is depriving you of one of the most valuable parts of the process. The walkthrough is your chance to learn your home from someone who evaluates homes for a living.

6. What Happens After the Inspection?

This question separates inspectors who see the job as a one-time transaction from those who see it as an ongoing relationship.

After your inspection, questions will come up. You might want clarification on something in the report. You might discover something six months after closing and wonder whether it was noted during inspection. You might want advice on a maintenance item the inspector mentioned.

Ask: "If I have questions after the inspection — even weeks or months later — can I reach you directly?" Find out whether you'll be calling the same person who inspected your home, or whether you'll be routed through a call center or customer service department.

Direct access to your inspector means faster answers, better context, and a level of accountability that larger operations often struggle to provide. When the person you call is the same person who was in your crawl space, the conversation is fundamentally different.

7. Do You Have a Conflict of Interest?

Some home inspectors also offer remediation, repair, or contracting services. This creates a financial incentive to find problems — or to find specific kinds of problems that generate additional business.

The cleanest arrangement is an inspector who inspects and does not remediate or repair. When your inspector has no financial interest in the outcome of the inspection, the findings are objective. You get the truth about the home's condition, not a sales pitch disguised as an inspection report.

Ask directly: "Do you or your company perform any repair or remediation work?" If the answer is yes, understand that the findings in your report may be influenced — consciously or not — by the revenue those findings can generate.

How do you read home inspector reviews the right way?

Online reviews are useful, but you need to know what to look for. A high star rating is a starting point, not the whole story.

Look for patterns across multiple reviews. The most telling signals are reviewers who specifically mention thoroughness, the inspector explaining findings during the walkthrough, timely and detailed reports, and — critically — responsiveness after the inspection was complete.

Red flags to watch for include reviews mentioning major issues discovered after closing, inspectors who seemed to rush through the home, difficulty reaching the company after the inspection, and defensive responses from the business owner when problems are raised.

Pay special attention to how the inspector or company responds to negative reviews. Defensive or argumentative responses to legitimate complaints tell you how you'll be treated if something goes wrong.

What is the most important thing to know when choosing a home inspector?

A home inspection is one of the few opportunities you have to understand the true condition of a home before you commit hundreds of thousands of dollars to buying it. The difference between a thorough inspection and a surface-level walkthrough can be tens of thousands of dollars in unexpected repairs.

Take fifteen minutes to ask these questions before you schedule. The inspector's answers will tell you everything you need to know about the kind of experience — and protection — you're going to get.
