"Robert was very pleasant to work with. He answered my request for a quote within minutes of my request. His price was lower than other quotes. He stayed in touch with me and showed up on time. Robert took his time and did a through inspection of my home. He explained issues he found and suggestion on how to fix some. His written explanation was documented with many pictures. I would highly recommend Robert for inspections of your home. 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!"

"Darrul did an amazing job with the home inspection. I arrived at the house 5 minutes early and he was already there waiting for me. The house is roughly 1300 sq feet and Darrul was there for a little over 3 hours. The report was sent to me an hour after the inspection was completed. The report was available in pdf format with linkable sections. At the end of the report was a summary with everything that Darrul found to be a concern or possible issue. It contained explanations of what is required to be inspected by the home inspector and what not is required to be inspected by the home inspector. It contained plenty of pictures and explanations of possible concerns or things that will need to be repaired or replaced. Darrul also did a great job of explaining different things in the house and answered any questions regarding improvement/renovation ideas. Based off of my experience I will recommend him to any friends and family."
