"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."

"Mike and his daughter performed the inspections. He was responsive to my questions and doubts and was able to set up the appointment for the next day. I would have expected that the smoke detectors along with the doorbell to be tested - I didn't think of this until after the inspection. I did ask him to check some of the lights (porch, closet) that maybe would have been missed. Price was higher than most but he was able to accommodate my timing."
