Radon testing for Denver homebuyers
Radon is invisible and odorless. Testing is the only way to know if a home has a problem and if mitigation is needed.
When to get radon testing
You should test for radon if:
The home has never been tested
You’re buying or selling the home
You’re planning or have finished renovations
It’s been two years since your last radon test
Test for radon before you close
You can either hire an Axium radon tester or purchase a radon test kit and do it yourself. The Environmental Protection Agency (EPA) recommends hiring a professional tester if you are buying or selling a home.

Radon testing vs radon mitigation
Radon testing tells you if you have a problem. Mitigation fixes it. Here’s when to get each service and what they include.
PHASE 1 · TESTING
Test your home
A state-licensed radon professional places a radon monitor in the lowest livable level of your home for 48 hours. Results are available the same day.
PHASE 2 · RESULTS
Understand your results
Your result is measured in pCi/L. The EPA recommends action at 2.0 pCi/L or higher. Colorado’s average is 6.3 pCi/L, well above that threshold.
PHASE 3 · MITIGATIONS
Fix it with Axium
If the levels are high, Axium’s state-licensed specialists can install a mitigation system to reduce your radon by up to 99%.
