"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!"

"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."
