How to compare mitigation providers in Fort Collins

The list above is alphabetical by the name on the credential record. A person can hold more than one credential, and several people can work for the same firm. Position in the list does not indicate a quality ranking.

  1. Match the license to the work. Check the name, number and current status in the Colorado DORA lookup. These mitigation records use RMT credentials; a measurement credential is a different scope.
  2. Confirm who will do the work. Ask which credentialed person is responsible, whether they can work at your property and what the proposed installation includes. The city on the official record is not a verified service-area promise.
  3. Compare written proposals. Ask about the system design, included work, warranty terms and how the radon result will be checked. The North Carolina radon program’s hiring guidance provides questions to discuss; confirm Colorado requirements separately.

Testing and local resources

Have a previous test report ready before discussing an installation. If you still need a measurement, compare the testing records for Fort Collins first. A city or neighborhood statistic cannot establish the radon level in your home.

City of Fort Collins radon program: The city radon page explains local testing options and links to Colorado's mitigation assistance program. Check the program directly for current availability and eligibility.

Questions before you hire

How do I verify a radon credential listed for Fort Collins, CO?

Open the source link on this page and match the name and credential number to CO DORA. Status can change after a record’s verification date. The latest record check on this page was September 11, 2026; check each record’s date. If the official page disagrees with this directory, trust the official page. We do not invent credential numbers.

Does EPA certify radon contractors?

The U.S. EPA does not certify radon contractors. EPA publishes guidance on finding a qualified radon service provider and points to state programs and national certifications. This directory is not affiliated with EPA. We do not display EPA-certified badges.

What does last verified mean on this page?

Last verified on an individual record is the date we checked its official source. The latest credential check on this page was September 11, 2026; other records may have earlier dates. We refresh the roster monthly. Current means the person appeared as currently credentialed on the source at that record’s verification date. Credentials can expire between refreshes, so follow the source link.

Appendix A.2

Before you hire

  1. Ask who holds the credential printed on this page, and ask them to show the same number. Some firms employ several credentialed people. The listing is the person or firm on the official file, not whoever answers the phone.
  2. Ask what test method or mitigation system they will use for this building. A credential is not a work plan. Testing and mitigation are separate services here, and a person appears on both lists only when the official file says they hold both.
  3. Ask how they will document test results or the finished mitigation system. Keep that document with the credential number you verified. This directory does not score jobs, publish reviews, or collect quotes.
