Eliminate your Radon problems! I highly recommend Cavalier Corporation to solve your Radon problems. We recently acquired a piece of property which needed a slight adjustment to the radon level....well, Cavalier Corporation virtually extinguished the problem! I'm so glad we called Cavalier Corp. Sylvia is very knowledgeable about Radon and the installation process. She'll answer all your questions including placement of product. Warren was great to work with as well.

Response to Jim Best Jim Best worked for us at Cavalier for about one year and we were very happy with his work and his efforts to please our customers. The recent actions of Jim and his wife are a great disappointment. After he quit with no notice it took us some time to check the last purchases on his company credit card. We then mailed him his paycheck. Warren and Sylvia Riddle, owners, Cavalier Corporation

very disappointed Worked very hard for them for a year, but the hours were not enough so told warren I had to find another job . He said he understood but when I went to get my last paycheck warren and Sylvia said fu and laughed at me. I am a family man but I do agree they re CROOKS. very very shisty. They can keep their lousy paycheck. Just happy to be gone.

Loved my system I had a radon system put in a while back. Even though it was not inexpensive, I am super glad I got it put in. After we purchased our home we found out we had high radon. The company came in told us that they could put our system in our laundry room, out of our way. The workers came in and were very polite and efficient. My system was done in one day. The company tested my home and gave me a free kit to check for my self later, my test came back below one. I chose to have the system put in because of the heal... read more

Absolutely Disgusted - Rebuttal Mrs. Riddle comments are factually incorrect and misrepresent the actual situation. We had the job site ready with a unpoured basement and very soft dirt for easy digging of the vented pipe -- this took less then 1 hour to install (Cavalier was told in advance of the project and the stage of completion when they provided the quote). There was a ten minute discussion with the installer on the 2nd trip on where to place the vent pipe -- a job was NOT completed (was simply run up to the attic and... read more

My radon is gone I had Cavalier come out and install a radon mitigation system in my home in 2008. My levels went from 17 to less than 4. The crew was quick, friendly and clean. No mess and they guaranteed the system.I think they are quite likely the best radon mitigation company in Spokane!
