Questions to Ask Before Hiring a Home Inspector

What Should You Ask a Home Inspector Before Booking?

Ask what license and certifications the inspector holds, request a sample report, confirm which add-on tests they offer and recommend for your home, and check that they can schedule inside your contingency window. Ask when the report is delivered after the inspection too. Those answers tell you whether the inspector is qualified and exactly what the fee buys.

What Certifications and Licenses Do You Hold?

Ask for the inspector’s state license number (required in most states) and professional certification (InterNACHI, ASHI, or NAHI). Some states require specific training hours and examinations for licensure; others have minimal requirements. Professional certification above state minimum demonstrates voluntary commitment to standards. Ask how many inspections the inspector has performed experience matters in a trade where pattern recognition is the primary diagnostic tool.

Can I See a Sample Report?

Request a sample report from a similar home type before booking. The report is what you receive for your money it should be readable, thorough, and organized in a way that helps you understand findings rather than just document them. Look for: specific descriptions of deficiencies, photographs of each finding, clear prioritization of findings by severity, and recommendations that are specific enough to act on. (For more on this, see How to Use Your Home Inspection Report to Negotiate.)

Do You Offer Radon, Termite, and Sewer Scope Testing?

Ask whether the inspector provides radon testing (certified equipment required), termite inspection (requires a separate pest license in many states), sewer scope inspection (requires a camera scope), and mold testing (requires sampling and lab analysis). Bundling available tests with the primary inspection saves scheduling time and sometimes provides a discount. For the home you are purchasing: ask which add-on tests the inspector recommends given the home’s age, location, and any known conditions. (For more on this, see How to Find the Best Home Inspector.) The EPA identifies radon as the second leading cause of lung cancer and recommends testing any home, new or old.

What Is Your Availability and How Quickly Will I Receive the Report?

Real estate transactions move on tight timelines a typical inspection contingency window is 7 to 14 days. Confirm the inspector can schedule within your contingency period and deliver the report within 24 hours of the inspection. An inspector who cannot schedule within your contingency window is not available for your transaction regardless of qualifications.

Working With a Contractor on This Project

Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.

Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.

Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.

Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.

Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.

Making a Confident Decision

The information in this article is designed to help you ask better questions of the professionals you work with, evaluate their answers with more confidence, and understand the decisions involved in this type of home services project. It is not a substitute for professional assessment of your specific home.

Every home is different. Roof slopes, local weather, tree exposure, soil conditions, and existing system condition all affect what the right solution is for your specific situation. The general principles here apply broadly, but a professional who assesses your home in person will give you guidance that accounts for the details that general articles cannot. (For more on this, see New Construction vs. Existing Home Inspections.)

When you are ready to move forward, getting at least two or three quotes from licensed, insured, local contractors is the most important practical step. It lets you compare approaches, assess contractor quality, and confirm that the solution proposed matches your specific situation and budget.
