"Dave was on time, courteous and quietly and efficiently did high quality work. We still need to do the radon test but definitely happy with the quality of work. Will update the review once we have been able to complete the independent radon testing. Thanks!"

"Matt inspected the property we are buying, and it's a complex property with a lot of different areas that needed to be looked at. He went over everything with a fine tooth comb - his attention to detail is incredible. His report gave us the confidence we needed to proceed, and a comprehensive list of areas that we'll want to address. Highly recommend him - probably the very best inspection we've had."
