FAQ: Radon Mitigation in Colorado

Why is radon so high in Colorado?

Colorado sits on uranium-rich granitic rock. The high altitude means lower atmospheric pressure, which draws more radon from the soil. Cold winters keep homes sealed tight, trapping radon inside.

Is radon testing required when buying a home in Colorado?

Not legally required, but radon testing is extremely common in Front Range real estate transactions. Most buyers' agents recommend it.

Should I test my Denver-area home?

Yes. The Denver metro is in EPA Zone 1. Individual homes vary widely — some test below 2.0 pCi/L while others exceed 20.0. The only way to know is to test.

How much does radon mitigation cost in Colorado?

Most homeowners in Colorado see mitigation quotes in the low-thousands, but the final cost depends on foundation type, fan location, and pipe routing complexity. A cost calculator can help you benchmark estimates before requesting bids.

Do I need radon testing in Colorado before hiring a contractor?

Yes. A valid short-term or long-term test is the fastest way to confirm if mitigation is needed and to scope the right system design.

What radon level is dangerous in Colorado?

EPA recommends action at 4.0 pCi/L, and many homeowners choose to reduce levels even below that threshold. Most of Colorado's Front Range corridor is EPA Zone 1 — the highest risk classification. Colorado has one of the highest radon testing rates in the country. ZIP-level lookup tools are useful for local context, but home testing is still required.
