Radon Mitigation
Residential Radon Mitigation
Radon is a radioactive gas that can seep into your home through foundation cracks, crawl spaces, and other radon pathways in the soil. Left unchecked, it can accumulate in breathing zones, increasing the risk of lung cancer over time. If a radon test shows elevated levels in your home, it’s essential to take action with a professional radon mitigation contractor who understands the science, safety standards, and local building codes for effective remediation.




Our Radon Mitigation Process

Assessment and Planning
Every mitigation project begins with a thorough evaluation of your home’s structure, radon entry points, and existing ventilation. We use radon detectors and review Radon Data Portal readings (when available) to determine the right system design.

Installation of the Mitigation System
Radon mitigation solutions often include soil suction or active depressurization systems, vent pipe installations with radon fans, and sealing of cracks or penetrations where radon can enter. These mitigation methods may also be integrated with drain tiles or sump systems for added protection. All installations meet or exceed National Radon Safety Board standards and comply with local building codes.

Post-Mitigation Testing & Verification
After installation, a short-term test is performed to verify that radon levels are reduced to below the EPA action threshold. We also provide guidance on system maintenance and periodic retesting.

Frequently Asked Questions – Commercial Radon Services
1. How long does it take to install a radon mitigation system?
Most systems can be installed in one day, although larger or more complex homes may require additional time.
2. Will sealing cracks alone fix my radon problem?
No. While sealing cracks helps reduce radon entry, it’s rarely enough to bring levels below EPA limits without a proper active soil depressurization system.
3. Do mitigation systems require maintenance?
Yes. You should check the radon vent fan regularly, monitor system gauges, and retest your home every 2–3 years.
4. Can radon come from my water supply?
Yes. While less common, radon in water from wells can contribute to indoor levels and may require separate treatment.
5. Is a passive system effective in all homes?
No. Passive systems are most effective in new Radon-Resistant Construction homes. Older homes with higher levels usually require an active system with a fan.

David Hall2025-07-15Trustindex verifies that the original source of the review is Google. Very easy to work with, and very professional. John2025-06-27Trustindex verifies that the original source of the review is Google. Kent and the folks at ColoRadon are awesome!! I have an old house (1920) that posed a few mitigation challenges. The ColoRadon guys were able to expertly solve for those challenges, and successfully mitigate the radon in our home, sweet home! Barbara Harris2025-06-10Trustindex verifies that the original source of the review is Google. Kent and his employee Kevin are exceptional. They listened to our concerns and devised a plan that would work for us. Our radon measured 40.0 - 41.0 which was unbelievable to me but that was the results of our mail in test. After Kent installed the mitigation system our test came back at 2.9. I cannot even tell you how happy this made me. Thanks to Kent and his thinking outside the box he made a system that worked! Kent also installed a radon mitigation system in another one of my homes two years ago and it's working fabulously. I highly recommend ColoRadon. Barbara Harris Christopher S2025-05-19Trustindex verifies that the original source of the review is Google. We were in the middle of moving in our new house and Kent with Colorado Randon made everything so simple, it seemed like so many other things kept going sideways and anything that had to do with his tasks got done amazingly! Thanks for being on time with all of your services and even going out of the way to serve us in our Radon needs. I appreciate everyone I talked to and worked on our system, professional, and top quality services with great pricing! I absolutely will recommend Kent and this company to everyone. Natayle Brown2023-06-14Trustindex verifies that the original source of the review is Google. We’ve worked with Kent several times, always a pleasure! He’s tested for radon and installed radon mitigation systems for us a few times. We won’t go anywhere else - highly recommend! Emily Olinger2023-04-24Trustindex verifies that the original source of the review is Google. Kent is wonderful! He responded to my request for service super quick and was at our house the following day for a consultation. He was knowledgeable and professional. He answered all of our questions and provided us with a quote on the spot. He installed our mitigation system in a timely fashion and left our space cleaner than he found it. I highly recommend ColoRadon for your radon mitigation needs! Thank you Kent! :) LORI PUDLINER2023-01-22Trustindex verifies that the original source of the review is Google. Kent did an amazing job. He did a great job communicating when he was going to be late. He was professional, courteous and cleaned up after himself. He was very thorough in explaining the process and the test after the installation. Michele Razzari2022-11-29Trustindex verifies that the original source of the review is Google. We were referred to Kent thru our realtor when we moved to Colorado. Kent was awesome to deal with while we still lived out of state. He checked in when we arrived to complete a 2nd test after our radon mitigation installation. He was awesome to work with and easy to get ahold of! Dan Pahlau2022-08-19Trustindex verifies that the original source of the review is Google. Kent has worked on my home in other capacities in the past, but with ColoRadon, he removed a pigeon infestation and added netting around my solar panels on a roof that I was not equipped to deal with. He was responsive in scheduling, as always, did great work, cleaned up the huge mess it made and came in under budget. Can’t recommend him more if you need handyman work or radon work done! (He did radon mitigation, mold mitigation, and roof repair on my last home). Alison Goin2022-02-20Trustindex verifies that the original source of the review is Google. Great service, Kent is there when he says he will be, performs the work needed efficiently - cleans up after. Stays in contact thru the entire process. Highly recommended! He genuinely cares about resolving any radon issues.
