Real Before and After Results
Colorado’s Lowest Radon Level Guarantee: 1.5 pCi/L or Less*
Our goal is not just to get radon results below the EPA action level of 4.0 pCi/L. It is to reduce radon as much as possible through diagnostics, testing, and a system designed for the home.

What Can You Expect After Radon Mitigation?
Every home is different. Soil conditions, foundation design, drain tile, crawlspaces, additions, existing radon systems, accessibility, and homeowner goals can all affect the final result. Because of that, no radon company should promise the same average radon levels after mitigation on every home.
However, we believe homeowners deserve to see real results of what a properly diagnosed and engineered radon mitigation system can achieve.
“Below 4.0 pCi/L” and “as low as possible” are not the same.
Many radon systems are designed mainly to get the home below the EPA action level of 4.0 pCi/L. Our process is designed for homeowners who want to reduce radon as low as possible.
We Perform Diagnostics on Every Home
Instead of simply picking a suction point, installing a fan, and hoping for the best. We use diagnostic testing, pressure field extension testing, radon monitoring, and system design to better understand how air moves beneath the home before finalizing the mitigation approach. This helps us design systems that are more complete and more effective, especially in homes with complex foundations, drain tile, crawlspaces, additions, or existing radon systems that are not reducing radon levels enough.
Our Goal Is the Lowest Achievable Level
There is no known safe level of radon exposure, so our goal is to reduce radon as much as possible. That does not mean every home will reach the same final number. Some homes could potentially be reduced even further, but the homeowner may decide the current result is acceptable and choose not to continue with additional work.
Why Post-Mitigation Radon Levels Vary
Radon mitigation levels can vary from home to home because no two foundations are exactly the same. The final result may also depend on how far the homeowner wants to continue pursuing additional reductions.
- ✔Foundation type
- ✔Drain tile layout
- ✔Additions
- ✔Sump pits and slab openings
- ✔Accessibility
- ✔Soil conditions
- ✔Crawlspaces
- ✔Block walls
- ✔Existing radon systems
- ✔Homeowner budget and authorization
