Radon Mitigation in Estes Park

7 radon contractors · 1 based in town, 6 serve Estes Park from the Front Range · Updated September 2026

Testing for radon is one job and fixing it is another, and in Estes Park the people who do the first mostly work as home inspectors from the Front Range. Seven listings appear in this category, and only one is based in the valley. That makes a few questions on the phone worth more than a quick search.

Marcus's take

Test first, then decide. I would not pay for a fix I had not measured. Ask any company whether it tests, mitigates or both, and who retests after the work. Most of the testing outfits up here drive from down the hill, so plan around the drive.

Inspections by Referral

He does the inspections himself, out of Loveland, and covers the area from Denver to the Wyoming border, coming up to Estes Park as well.

What to know

Radon Home Measurement and Mitigation in Fort Collins is the one listing that describes both testing and mitigation, and it runs its own testing laboratory. Pandion Property Inspections in Berthoud lists a Colorado licensed Radon Measurement Professional. Quality Home Inspections and Centerline Home and Building Inspections, both in Loveland, list radon testing alongside general inspections.

Because most listings are inspectors, radon often rides along with a home sale. Inspections by Referral lists buyer and pre-listing inspections and covers Estes Park, and Bulls Eye Inspection is the local choice for general inspections with thermal imaging on every one, though its description does not mention radon. Ask each inspector directly whether they test and whether they also install fixes.

Two listings carry the licensed tag, two offer free estimates and five are tagged residential. Quality Home Inspections also lists well system and water testing, worth knowing since many homes outside town limits are on wells. Lion Septic Service shows up here too, but its description mentions septic work, not radon. Whatever you hire, ask for the radon reading in writing before and after any work.

Who tests for radon in Estes Park?

Radon Home Measurement and Mitigation, Pandion Property Inspections, Quality Home Inspections and Centerline Home and Building Inspections all list radon testing. Quality Home Inspections and Centerline name Estes Park in their service areas. For the others, confirm they travel to your address.

Is there a radon mitigator based in Estes Park?

Not in this list. Only one of the seven listings is based in the valley, Bulls Eye Inspection, and its description covers home inspections, not mitigation. The company that describes mitigation is Radon Home Measurement and Mitigation in Fort Collins. Call to ask about travel to Estes Park.

Do radon companies offer free estimates?

Two of the seven carry a free estimates tag: Radon Home Measurement and Mitigation and Lion Septic Service, though Lion is a septic company. For testing, ask about price and what the written report includes before you book.

Can a home inspector test for radon during a sale?

Several listed inspectors do. Pandion, Quality Home Inspections and Centerline list radon among their services, alongside buyer and pre-listing inspections. Ask whether radon testing is included or priced separately, and how long the test needs so you can fit it around a closing.
