"My husband and I are writing to communicate to you a very positive interaction with Mr. Tim Peiffle. His professional approach to a radon inspection, which was mandatory in the conduction of the sale of our home, displayed a knowledgeable background, as he also educated my husband and myself, as to the radon process. His service was stellar!"

"I consulted with Radon Doctor about my home. The four foot high basement had 5 pci in a 48 hour test. The first living floor was 1.5 pci in the same test. Radon Doctor advised me to monitor radon levels on the living floor over 6 months during winter season and get back to them for mitigation if needed. They did not take advantage of a single basement reading to insist I install a system that would not affect the living floor levels. These guys are legit."

"Inspection went very well. Very thorough. It more than paid for itself. House Doctors's is licensed by the State to do home inspections, and licensed to actually educate and train other home inspectors. They seem like they want to work for YOU not the realtor."
