Overview
Crawlspace Radon Mitigation in Arvada
Crawlspaces are one of the most common—and most challenging—radon entry points in Arvada homes. Exposed soil under a crawlspace lets radon seep directly into the air you breathe, and that air rises into your living space through the stack effect.
Our crawlspace solution combines a heavy-duty sealed vapor barrier with sub-membrane depressurization. We lay and seal the membrane across the soil, then draw radon-laden air from beneath it and vent it safely outside. The result is lower radon, drier air, and a healthier home.
Arvada sits on the kind of uranium-rich Front Range soil that makes Colorado one of the highest-radon states in the country. That's why crawlspace radon mitigation is so important here—from historic Olde Town bungalows to new builds out toward Leyden and Candelas, local homes routinely test above the EPA action level.
Sealed Vapor Barrier
Commercial-grade membrane fully seals the soil, blocking both radon and moisture.
Sub-Membrane Suction
A dedicated fan pulls radon from under the barrier before it can enter your home.
Drier, Healthier Air
Sealing the crawlspace also reduces humidity, mold risk, and musty odors.
Built to Last
Durable materials and clean routing mean a system that performs for decades.

FAQ
Frequently Asked Questions
Answers to the most common questions from Arvada homeowners.
Yes—crawlspaces with exposed or unsealed soil are a major radon source. Even if the crawlspace is vented, radon can still accumulate and rise into your living areas. A sealed sub-membrane system is the most effective fix.
Absolutely. The same sealed vapor barrier that blocks radon also dramatically reduces ground moisture, which helps prevent mold, wood rot, and that musty crawlspace smell.
A slab system draws radon from beneath your concrete foundation, while a crawlspace system uses a sealed membrane over the soil with suction underneath it. We assess your home and recommend the right approach.
Yes. We serve all of Arvada, Colorado—including Olde Town Arvada, Candelas, Leyden Rock, West Woods and surrounding ZIP codes like 80002, 80003, 80004—plus nearby Westminster, Wheat Ridge, Golden.
Arvada sits on the Colorado Front Range, where uranium-rich soil produces high radon levels. The EPA places this region in Zone 1, the highest-risk category, so testing and mitigation are strongly recommended for local homes.
