"The Buyer's Inspector was extremely thorough. I have heard it said that he is the "pit bull" of home inspectors. He left radon detection equipment behind for over 50 hours. He offered additional water testing at my request. He has provided me with a itemization of all things good, marginal, bad, dangerous of every aspect of my house. He cross referenced these comments with pictures and suggestions. He seemed highly knowledgeable. It will be easy for electrician, plumbers, chimney sweeps, etc. to understand and locate the problem areas in the home. But beware when you schedule: My inspection lasted 6 hours!"

"I hired Double Check to do an inspection for a personal decision of "Repair or Replace". Justin came out, performed the inspection, took photographs and answered all my questions. He found some issues like a few shingles missing, popped nailheads and the like. We discussed the Repair or Replace decision. Very knowledgeable and easy to deal with. Highly recommended."

"Bilal went above and beyond for me. I was supposed to have new flooring done on a Saturday, they said it could be asbestos on the tiles under the carpet and couldn't work until it was tested. Obviously I was devastated. He came out that afternoon, took the samples Monday to the lab so I could get same day results. Came out Tuesday to remove everything. Wednesday took the air sample to the lab for same day results. Completely above and beyond to help me and I'm very greatful. Thank you!"
