Home Inspection questions, answered by experts

A sagging, cracked, or uneven foundation, worn or outdated electrical systems, poor plumbing, and slow sewer lines are all common deal breakers that stem from home inspections. Musty odors, uneven floors, and sticky doors and windows may also be deal breakers that will tell you when to to walk away from a home inspection.

Most areas require both a building permit and an electrical permit for the installation of a home wind turbine. You may also need zoning approval, especially if your property is in a residential neighborhood or near protected land. Inspections are needed after foundation work and upon completion of electrical connections. Permit costs can range from $100 to $1,000, depending on local regulations and project complexity.

A standard roof inspection usually takes anywhere from 45 minutes to a few hours , depending on the roof's size, complexity, and condition. Make sure you allow enough time for a thorough inspection by asking for a time estimate when you hire your inspector.

The size of your home, whether it’s a structural inspection versus a home inspection, and the inspector’s experience and skill level will dictate how long a home inspection takes. However, inspections are generally completed in 30 minutes to half a day.

Yes. If a home inspection reveals that the property has major issues or is unsafe, the buyer can back out of the purchase.
