Radon Mitigation Service in Denver, CO

Investing in radon mitigation services has become a “must do” to ensure the health and safety of homes and businesses. Buildings can gradually accumulate radon, a colorless and odorless radioactive gas, particularly in lower levels, such as crawl spaces and basements. Significant health concerns, especially lung cancer, are associated with prolonged exposure. In order to detect, lower, and keep radon levels within the EPA's safe criteria, professional radon mitigation systems are built. Radon management is becoming more and more important to homeowners, property managers, and real estate professionals as a crucial component of responsible property maintenance due to increased awareness and legal requirements.


Modern radon mitigation services combine technology, science, and personalization. To determine radon levels and create ventilation systems that are specific to the layout, soil composition, and foundation type of each building, technicians employ sophisticated diagnostic tools. The most popular technique is sub-slab depressurization; however, depending on the circumstances, additional strategies such as crawl space encapsulation or air exchange systems can be used. Most systems are implemented in a single day, making the procedure quick and minimally invasive. Long-term peace of mind is provided by post-installation testing and ongoing monitoring, which guarantee performance and adherence to safety regulations.


Reputable radon mitigation businesses give education, openness, and continuing assistance in addition to installation. Customers receive thorough evaluations, transparent pricing, and support from industry certifications. Expert providers are a benefit during property inspections and sales since quick return times and paperwork are essential for real estate transactions. Investing in a top-notch radon mitigation program not only protects tenants but also increases the credibility of the property in a market where health-conscious decisions are increasingly influencing value and trust.


At Radon Free Colorado, LLC, we prioritize precision, safety, and long-term performance in every mitigation system we install. Our experienced team uses advanced techniques to deliver dependable results, earning the trust of homeowners and businesses across Denver, CO.

Happy Customers in Denver, CO

Extremely knowledgeable and down to earth guy. So hard to find good contractors these days - but he is very fair with pricing and very good and what he does. I am a Realtor and will continually use him for my business and my clients. Can't recommend highly enough!

Phillip B.

Aaron and radon free Colorado did a great job with our radon mitigation. Unsafe levels were common in our basement until they did our radon mitigation. After the install, we have not seen unsafe levels.



Aaron also helped us with a sump pump emergency recently, for which I am very grateful!

Aaron is hands-down the best at what he does. We had a home closing scheduled just 2 weeks out & he found a way to squeeze us in the day before closing, despite his VERY busy schedule. He's busy for a reason: he's personable, he's professional, and he knows how to get the job done. Our Radon mitigation system was installed correctly the first time, not just on the home we were selling, but also the one we turned around & bought! I couldn't speak more highly of his work.

Christopher B.

Aaron was amazing to work with. He responded quickly to my call and was able to get out the next day! He was on time not some 6 hour window. When he was here he was professional. He gave options to what we needed and explained the best option. He educated us about our current set up and what he added. He is clean and did not leave the work area dirty! I would highly recommend this company!
