Radon mitigation quotes in Aurora
Aurora is Colorado’s third-largest city, spreading east from Denver across Arapahoe and Adams counties with housing from postwar neighborhoods near the old core through vast newer subdivision growth toward E-470.
Front Range radon levels are among the nation’s highest. We introduce Aurora homeowners to independent, nationally certified mitigation contractors for free quotes.
Aurora and Arapahoe County
Aurora routes through our Arapahoe-Douglas territory, which also covers Englewood, Greenwood Village, Centennial-area ZIPs, Parker, and Castle Rock. EPA places Arapahoe County in Zone 1 on its Map of Radon Zones. Colorado does not license radon professionals; look for NRPP or NRSB national certification.
If the result surfaced in a transaction
Aurora’s market spans first-time buyers, military-adjacent relocations, and family moves, all with radon testing as standard practice. Colorado requires sellers to provide a radon warning statement and the state brochure before a sale; nothing requires testing or mitigation, and the remedy is negotiated.

The housing you’re mitigating
Older western Aurora brings postwar ranches on block foundations, many with crawl spaces rather than full basements — crawl-space designs use sealed membranes with suction drawn beneath. Newer eastern subdivisions are conventional poured construction with deep basements, sump systems, and frequent passive rough-ins.

Aurora questions, answered straight
Our house sits on a crawl space. Can that be mitigated?
Yes. The standard approach seals a durable membrane over exposed crawl-space soil, seals it at walls and seams, and draws air from beneath it with a fan venting above the roofline. Confirm the quote covers the whole crawl area rather than part of it.
Is a newer eastern-Aurora home less likely to test high?
No. Radon comes from the soil beneath the slab, and Front Range soils produce it regardless of build year while tight construction holds what enters. Many newer homes have passive rough-ins, which makes the fix smaller — not immunity.
How do we verify the system worked?
Insist the post-mitigation radon test be in the scope of work. Run under closed-house conditions after startup, it proves the indoor number dropped rather than merely that the fan is running.
