Westminster is home base for Custom Radon Solutions. From established brick ranches near the historic core to larger homes around Standley Lake and newer northwest neighborhoods, we understand the range of foundations and routing challenges found across the city.
Radon enters when naturally occurring soil gas is drawn through openings in the foundation. A professionally designed active system reverses that pressure by collecting gas beneath the home and exhausting it safely above the roofline. We tailor suction points, sealing, and fan capacity to the building.
Most Westminster installations take 3–4 hours. Our below-2.7 pCi/L guarantee, lifetime warranty, free estimate, complimentary test kit, and local service make the process straightforward from first test to confirmed result.
Radon has no color, smell, or taste. A professional test and a system designed around your actual foundation are the reliable path to a verified result.
Foundation-specific design
The right mitigation method for your home
Every system uses active soil depressurization, but the way we collect soil gas depends on the foundation beneath your lowest occupied level.
Basement & sump systems
A sealed sump lid or sub-slab suction point captures radon beneath the concrete before it reaches finished living space.
Crawlspace mitigation
A durable, sealed membrane covers exposed soil and connects to active suction for continuous soil-gas control.
Slab & mixed foundations
One or more carefully placed suction points create negative pressure across slab-on-grade, additions, and split foundations.

Built for local homes
Local radon expertise for Westminster foundations
Westminster homes commonly include full basements, split-level slabs, sump systems, additions, and occasional crawlspaces. Properties built over several decades may have distinct foundation sections that do not share air beneath the slab.
We diagnose those conditions before installation and choose an efficient system layout. Because our office is in Westminster, homeowners also have a local team available for questions about the system and warranty.

How long does radon mitigation take in Westminster?

Yes. Schedule a free in-person estimate and we provide a complimentary radon test kit. Testing helps establish the starting level and post-install testing verifies the result.
