Radon mitigation in Golden, Colorado
Golden 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
Golden homes back up against the foothills where bedrock is close to the surface — a common reason radon readings climb well above the EPA action level.
We are based in Denver and work Golden 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 Golden
- 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 Golden as part of the job.
If you are closing on a house in Golden and the inspection turned up an elevated reading, tell us the date. We build the schedule backwards from it.
Other cities we serve
We work throughout the Denver metropolitan area, not just Golden.
