FAQ
Frequently Asked Questions
-
The EPA recommends action at 4.0 pCi/L or higher. Colorado’s average indoor level is 6.3 pCi/L — well above that threshold. If your test comes back at or above 4.0 pCi/L, mitigation is strongly recommended.
-
Most Denver systems run between $800 and $2,500, depending on your home’s size and complexity. Axium provides free estimates so you know exactly what to expect before committing.
-
Most installations are completed in a single day — typically 2 to 4 hours. Our certified specialists work around your schedule to keep disruption to a minimum.
-
Yes. Axium’s sub-slab depressurization systems reduce radon levels by up to 99%, backed by a lifetime guarantee and verified with post-mitigation testing.
-
A properly installed system lasts 10 to 20 years. The fan is the only mechanical part and is easily replaced. Our workmanship guarantee covers the install for as long as you own the home.
-
Rarely under standard policies. But if elevated radon is found during a real estate transaction, costs can often be negotiated into the sale — and Axium provides documentation to support your claim.
