About us
We are a locally-owned radon mitigation company serving families along the front range of Colorado. Radon is a radioactive, lung cancer-causing gas, and half of Coloradans have it lurking in their homes. We test for and lower toxic levels in your home so you can stay healthy and get high on life, not radon. After more than a decade as a trained respiratory therapist, our owner Darren Corso has seen first-hand how essential lung health is to the longevity of our lives. Unfortunately, in Colorado, radon is a major threat to that livelihood. Darren started Mile High Radon Control to stop the problem in your home before it becomes one in your body. We’re certified, A+ rated, and committed to getting the job done right. Learn more about the Mile High Radon Control difference on our website. milehighradoncontrol.com.

Down to earth, quick response, answered all my questions and came for a free estimate. No games or surprise charges. The job was done exactly how we discussed in the estimate. You won’t regret going with these guys.

Darren came out to install a radon system in our new home. Darren was affordable, professional and FULLY LICENSED. Fully Licensed and trained was something most of the other contractors lied about after a simple google search. Darren worked with us to ensure that the system was installed where we wanted inside our home and outside. Thank you Darren for making our home safe!

My new house's radon test came in high enough for the inspector to flag it. After moving in, I called up this company and got a hold of Darren. Quick and easy process. He came out for an estimate within a few days, then again 2 weeks later to install the system in an afternoon. He even painted the vent to match the siding, no extra cost (though I did provide the paint/supplies)! Price was very reasonable. I high recommend these guys!

There were several complications with my house and schedule. Darren worked through each issue and concern with patience and expertise. He was very helpful, went above and beyond his scope of work and made recommendations that really helped us out. I especially liked the level of communication. He made it easy to schedule. The pictures and video helped me understand the concerns and make decisions that kept us on track. I felt so confident in his work that I had him remediate the house where my grandchildren now live. Highly recommend!

Darren was very courteous and polite, very knowledgeable of the project! Patrick did an awesome job on installing the system, it's not noticeable like our neighbor's. Ours blends into the side of our house! Great Job!! "The project was top notch. Not only did they consistently show up on time and finished in good time. Final project turned out great!"

We received excellent care from Darren and Artero. Our radon level came back extremely high and once the new radon system was installed, it dropped to less than 2! We are beyond thrilled with the results and the professional care given us by Mile High Radon! If you are having radon issues, Mile High Radon will more than take care of you!

Darren stood out above five other bidders. He came across much more knowledgeable, explained the process more thoroughly and answered questions more completely. Darren, Willim and Jimmy showed on time and worked a very long Saturday, non stop. They were all courteous and friendly throughout the day. The job was done very professionally. Looked great and they completely cleaned up before leaving. I highly recommend this company to anyone who wants it done right.

Darren did a great job installing our system. Great person and when I received the email confirmation stating our bill was paid this is on there as well "For every radon mitigation a portion of your payment will be donated to THORN." It is nice to see they donate money to a good cause.
