A good home inspector catches problems before they become expensive disasters—but only if you ask the right questions. Before you hire someone to evaluate a property, know what to expect from their process, credentials, and follow-up. This guide walks you through the critical questions that separate thorough inspectors from mediocre ones.
Credentials and Licensing
Ask your inspector about their certifications first. In most states, home inspectors must hold a state license; verify this directly with your state's regulatory body rather than taking their word for it. Beyond licensing, look for memberships in professional organizations like the American Society of Home Inspectors (ASHI) or the National Association of Home Inspectors (NAHI)—these require continuing education and adherence to a code of ethics.
You should also ask how many inspections they've completed and how long they've been in business. An inspector with 500+ completed inspections typically spots problems faster than someone with 50. If they've been operating for fewer than three years, ask what relevant experience they bring from prior careers in construction, plumbing, electrical work, or property management.
Scope and Process
Ask what's actually included in their standard inspection. Most home inspectors cover the roof, foundation, HVAC systems, plumbing, electrical, and interior/exterior structures—but don't assume. Some inspectors charge extra for pest inspections, mold assessments, radon testing, or septic system evaluations, which can add $150–$400 each.
Request the inspection timeline. A thorough 2,000–3,000 square foot home typically takes 3–4 hours. If an inspector quotes 90 minutes for the same size property, they're likely rushing. Ask whether you can be present during the inspection—most inspectors encourage this so they can explain findings in real time.
Report Delivery and Detail
The inspection report is your main deliverable. Ask what format and timeline to expect—most professional inspectors deliver a detailed written report within 24 hours via email, often with photos and clear categorization of issues by severity (critical, major, minor, informational).
Find out whether they use narrative descriptions, checklists, or both. A good report doesn't just say "roof needs attention"—it explains why (curled shingles, missing flashing, lifespan) and provides rough cost estimates for repairs when possible. Ask if the report includes a prioritized list of recommended repairs or systems that need professional specialist evaluation.
Liability and Follow-up
Ask about their errors and omissions insurance coverage. This protects you if they miss a major defect. Most reputable inspectors carry $500,000–$1 million in coverage. Request the name of their insurance carrier and coverage limits—it's a red flag if they can't provide this immediately.
Clarify their follow-up availability. If you have questions about the report after you receive it, will they answer by phone or email? Do they charge for consultations? Some inspectors offer a brief follow-up call at no charge; others charge $50–$150 per question.
Key Questions Checklist
Before you book, pin down these specifics:
- What professional certifications and licenses do you hold, and in which states?
- How many inspections have you completed in the past two years?
- Does your quote include mold, radon, and pest assessment, or are those add-ons?
- Can I be present during the inspection, and how long will it take?
- When will I receive the written report, and what will it include?
- Do you carry errors and omissions insurance? What are the coverage limits?
- Will you be available for follow-up questions, and what's your fee?
Finding and Comparing Inspectors
Interview at least two to three inspectors before deciding. Check online reviews on Google and Yelp, but weight recent reviews more heavily. Ask your real estate agent for referrals—they work with inspectors regularly and know who's reliable.
Price matters, but it shouldn't be the only factor. Standard home inspections typically range from $300–$600 depending on property size and location. Mercoly helps you compare and find trusted home inspection providers in one place, so you can review credentials, read customer feedback, and get instant quotes without the back-and-forth.
Frequently Asked Questions
Q: What should I do if the inspector finds a major problem with the home? A: Request a detailed repair estimate in the report, then hire a specialist (electrician, plumber, structural engineer) for a secondary evaluation if the cost is significant. Use this information during price negotiations or to decide whether to walk away.
Q: Can I negotiate my offer based on inspection findings? A: Yes—most real estate contracts include an inspection contingency period (typically 7–10 days) where you can request seller repairs, ask for a credit toward closing costs, or terminate the deal with no penalty if major issues emerge.
Q: How much weight should I give to an inspector's cost estimates for repairs? A: Take them as ballpark figures only; they're trained to identify problems, not price specific contractor work. Always get licensed contractor bids before committing to repair costs.
