About Us Cavalier Corporation entered the radon industry in 1986 and soon became the northwest's leading experts in radon testing and radon mitigation . Owners, Warren and Sylvia Riddle promptly availed themselves of all available radon training and credentials: * Environmental Protection Agency * National Radon Safety Board * National Environmental Health Association Cavalier was one of the first companies in the nation to guarantee that every radon mitigation system they installed would achieve radon levels below the EPA recommended action level, 4 pCi/l. On average, Cavalier achieves reductions to about 1 pCi/l in existing structures. Cavalier has mitigated hundreds of existing structures including almost 300 structures at Fort Lewis, 16 structures at Mukogawa Fort Wright Institute, 9 structures at Gonzaga University, 3 banks, and hundreds of commercial buildings and homes. When the Washington State Legislature enacted the Ventilation and Indoor Air Quality code in 1991, requiring radon systems in new housing, Cavalier had already been installing guaranteed systems in new homes for several years. Hundreds of builders have hired Cavalier to install guaranteed Cavalier radon systems in thousands of Spokane's new homes.

I highly recommend Cavalier Corporation to meet all your Radon needs. Sylvia is very knowledgeable about Radon and your installation needs. She and her husband work as a team to meet your needs. Warren worked in a timely manner to install the Radon system, while Sylvia handles the paperwork. But the best part, are their results! I got the highest score you can receive, which is to say a Radon level of 0.3. It may not be cheap but it works.
