"Jim Shuster was prompt, professional, extremely knowledgeable ... and very pleasant to work with! The initial response to my inquiry was quick, as was all subsequent communication. I was so impressed with the overall Radon Testing experience that I also contracted with Jim to perform an Air Quality Test and Mold Inspection at my residence. I do not think that I could have received a better reference for my job(s) than Premier Inspections Plus. Thank you."

"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!"

"Did a great job wit the inspection and I feel a lot more confident about the move. The only downside was he showed up a half hour late. I'm sure it happens from time to time, but it is something to be noted if you are in a time crunch."
