"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!"

"Radon gas in my house’s lower level was 3.6 picocuries per liter: below 4.0 pCi/L, at which EPA urges remediation, but high enough that it’s recommended. Beginning a week after SWAT installed gas elimination system (for $850), radon level dropped to 0.3 pCi/L: about the same amount of radon as is found in fresh air. Nuff said."
