An absolutely perfect experience with Kent and his team. Kent proposed a quick solution, and worked to make the installed system nearly invisible. The fan is completely silent, and we went from readings over 10pCi/L to below 2!
Enthusiastically recommended.

Coloradon was by far the best radon mitigation company to work with. He took the time to do the measurements in the crawl space. His scheduling was prompt and his work was quick and very well done. They are just a good honest company who do great work. We have nothing but good things to say about Coloradon. Use Coloradon! Thanks again Kent and Team!

Kent and Kevin were very thorough, and did a great job with our radon mediation. The output pipe looks just like our drain spout and the interior work is professionally done and was clean when finished. I would definitely recommend their work!

Working with ColoRadon was super easy. They were very responsive, communicated well, where very knowledgeable, and did an amazing install faster than i could have imagined. I was impressed enough that I passed them along to my good friend who also went with them.
They did an install that ran up from the basement, out the garage and up through the attic.
The radon mitigation system that ColoRadon installed was super clean and tidy. The test that he completed afterward showed that the radon level in our basement went from 12 to 1.9! That is a huge improvement! Another side benefit is that the system has pulled so much humidity out of the basement that the dehumidifier hasn't turned on once in a week since the system was installed. Kent and his team are friendly and very knowledgeable. The price was very reasonable as well. I highly recommend this company!

Jason, thanks for letting us help out. We are glad the radon mitigation system is working so well and helping out with the humidity. Crazy that those fans can pull not only the radon, but also that much vapor as well. Take care and thanks again for a good word.
