"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."

"Jose Rodriguez was prompt, professional, and fast with results. He was there when he said he would, went there the next day after I called, and provided the results on time. As a real estate professional I know I'll need the services again and I know that he is the person I will be calling. Thank you!"

"Chuck was thorough, personable, and very helpful. He went above and beyond to give us helpful pointers and information that was beyond the scope of what was required for the inspection. I highly recommend his services!

"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."
