Mile High Radon Control, LLC

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.

Darren took an incremental approach to our radon problem. Rather than throw everything at the problem, he suggested the initial abatement system and then to follow up with other solutions as needed. He was quick to respond, professional, and knowledgeable. The exhaust system blends in with our gutter downspout. He almost took the reading down to zero. Great job. Thanks Darren!

Hands down the best experience i have had getting things done to my new house. He and his crew were respectful and did great work. Their were no hidden fees and what we agreed upon when he quoted me was exactly what i paid. He came to the site and made sure that thr job was not going to require any thing abnormal. No one else came to the house and just gave me a quote over the phone. I really couldn't have asked for a better experience and I am completely satisfied!

Darren and his team arrived as promised and were very courteous and friendly while being completely professional. They did the job as explained and left the house clean. Darren has followed up 2 times in the first week to check on the readings. More work may be required to get the readings to an acceptable level and I am confident he will do whatever is required.

Darren was awesome! He's very professional, thorough, and was flexible scheduling the install. He used gutter piping which he ran up our trim making it almost completely unnoticeable. It looks great! I would definitely recommend him!

Could not ask for more! We found Darren to be an intelligent, articulate, perceptive professional who is a master of the systems and setups he offers. He patiently explained to us the best route and system for our situation. His work quality, installation, and cleanup are 110%. If we had to do this again, I'd go with Darren for sure. Thank you!

Darren was great to work with. He was very flexible with our schedules and you can t beat his prices. We ve seen a lot of radon systems installed and ours is one of the best we ve seen. He used white gutter pipe rather than the round PVC and it looks 100x better. I would recommend him to everyone needing a radon mitigation system installed

Darren went above and beyond. Provided great advice on options and didn't try to upsell me. Dropped my radon levels from 7.9 to 1.02.

Great job, Great price and Darren was great explaining everything. The quality is excellent and the Radon went from 14 to 1.78 in one day on a digi meter. I would recommend Darren and plan on using him for my Daughters homes.

I highly recommend Darren and Mile High Radon. He was proactive in contacting me and made a trip to our house over the weekend to assess the job. He was very accommodating in making sure it got done as quickly as possible. He was professional and the work was excellent.

Darren from Mile High Radon Control was the first pro from Home Advisor to reach out to me, and he was flexible around my schedule to come see the work location in the house and give me a quote. His prices are quite reasonable and the craftsmanship is very good quality. Throughout the process of installation, he showed me how it was going which was great; he was able to drill right up next to the footer of the foundation of my house to retain as much space as possible indoors. The system looks tidy on the outside of my house. Less than a week since the install was completed, the short term reading on my wall unit radon detector (which averages the levels over the past 7 days) was already down in the 1.x pCi/L range; before mitigation the levels were consistently over 4 pCi/L.

Like most vendors in this catagory, a smaller shop, but listened well, did exactly what they committed to. Quality of work was very good.
