Colorado Radon Guide is an independent editorial resource for Colorado homeowners, buyers, and sellers navigating radon — what it is, why Colorado is exceptional, what testing costs, what mitigation costs, and how to find a qualified contractor.
What we do
- Publish editorial guides drawn from public sources: CDPHE, the EPA, El Paso County Public Health, Denver Public Health, and the Colorado General Assembly.
- Connect homeowners with a licensed Colorado mitigation partner when they request a quote. We are paid a referral fee when this happens — see our editorial and lead disclosure.
- Make cost transparent. The single biggest complaint we see in Colorado homeowner forums is "is my quote too high?" We publish typical ranges from authoritative sources so the answer isn't "ask three contractors and hope."
What we don't do
- We are not a radon contractor. We do not install systems, perform testing, sell equipment, or hold any radon professional certifications.
- We do not publish fake reviews, fake testimonials, or paid placements as editorial.
- We do not provide medical or legal advice. We summarize public guidance and link to the originals. For your situation, consult a physician, attorney, or licensed contractor as appropriate.
- We do not sell your contact information to multiple buyers. Quote submissions go to one licensed partner per inquiry.
Why this site exists
Colorado has one of the highest indoor radon rates in the country, real laws around disclosure (SB23-206), and active state regulation of radon professionals (DORA). But the actual experience for a Colorado homeowner who fails a radon test is still confusing: contractors give very different quotes, the legal disclosure rules are easy to misread, and most published cost guides are written by contractors selling the service.
We try to be the page you'd want a friend who happens to know radon to send you: clear, sourced, no scare tactics, and willing to tell you when DIY is fine and when it isn't.
