Radon mitigation in Commerce City, Colorado

Commerce City homeowners trust 5280 Radon Mitigation for testing, system installation, and service — with a fixed written price and a test afterward that proves the result.

Local radon, local installers

Commerce City homes on the north side often combine slab-on-grade foundations with a single floor drain — a setup that responds very well to one well-placed suction point.

We are based in Denver and work Commerce City every week — for homeowners who tested high, for buyers who need a system before closing, and for families whose fan finally wore out after fifteen years of quiet service.

What we do in Commerce City

  • Radon testing, including certified 48-hour tests for real estate
  • Sub-slab, crawl space, and block-wall mitigation systems
  • Sealing sumps, drains, and slab penetrations
  • Fan replacement, re-sealing, and service on existing systems
  • Post-installation verification testing

How it works

Call or send the form with your address and any test result you have. We ask a few questions about the foundation, give you a fixed price in writing, and schedule a day — most installations are finished in one day. Colorado permits vary by jurisdiction, and we handle the permit and inspection for Commerce City as part of the job.

If you are closing on a house in Commerce City and the inspection turned up an elevated reading, tell us the date. We build the schedule backwards from it.
