I can't say enough good things about Colorado RadonMitigation. From my first interaction to the final radon test, everything was handled with the utmost professionalism.My Denver house was built in 1912, so nothing is ever straightforward, but the team didn't skip a beat. They figured out the best possible installation strategy for a challenging layout and managed to get our radon results down below 1.0!A special shout out to Axel and Keelan for the design, the flawless installation, and for taking the time to explain the entire process to me. I highly recommend Colorado RadonMitigation.

Hi Nicole,
Thank you so much for the incredible review! We’re thrilled to hear that your experience — from the first interaction through final testing — was smooth and professional, especially given the unique challenges of an older Denver home. Axel and Keelan will be so glad to know their design, installation work, and walkthrough made a positive difference. And we’re especially happy your results are now below 1.0 pCi/L!
We truly appreciate your trust, your kind words, and your recommendation. If you ever need anything down the road, we’re here for you.
Warm regards,
The Colorado Radon Mitigation Team

Axel, Joshua and team were super communicative, efficient, snd effective . They gave us great peace of mind by drastically reducing our radon levels. They redid our crawl space encapsulation and radon system for a fair price. Would highly recommend.

The two installers from Colorado RadonMitigation were there most of the day and the system seems very solid. I am happy that the fan used was not loud to be invasive to the surroundings.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We are competitively priced relative to the local area and industry as a whole nationally. We happily offer realtor, builder, Veteran and repeat customer discounts!
We provide free in-person assessments within the greater Denver area and along the Northern I-25 corridor. Mountain and Plains communities will require a small trip charge if an in-person assessment is necessary which will be credited back should you choose our services.
Standard sub-slab radon reduction systems where a sump pit can be retrofitted start at $1.2k with more complex systems that require more powerful fans and multiple suction points to achieve the lowest radon levels possible ranging upward to $1.8k+. Total crawlspace encapsulation and sub-membrane radon reduction systems typically start at $1.5k depending on the size of the crawlspace.
All of our systems come with a post-mitigation measurement included per AARST standards!
What is your typical process for working with a new customer?
We will discuss your requirements over the phone and schedule a convenient date and time to visit the property to do a full walk through (if necessary) and design the system with the property owner's or builder's input. We will be able to discuss any preferences and any (observable) challenges up front and how that may change the scope of work and pricing. We promise to be as upfront and transparent from the beginning which will be reflected in our follow up quote on the day of the assessment.
What education and/or training do you have that relates to your work?
Our team is fully certified through NRPP and licensed for radon measurement and mitigation through DORA. We are proud members of AARST and work to the highest national standards set by them.
