Denver homes sit on Colorado Front Range soils where uranium naturally breaks down and releases radon gas. The gas can enter through slab cracks, plumbing penetrations, foundation joints, sump pits, and exposed soil in crawlspaces. Because neighboring houses can test very differently, the only reliable way to understand a property is to test it.

Custom Radon Solutions designs residential systems around the actual foundation—not a one-size-fits-all pipe route. We inspect the basement or crawlspace, identify practical suction points, account for additions and mixed foundations, and route the system to protect performance while keeping the finished result clean.

Most Denver installations are completed in 3–4 hours. We guarantee the completed system will reduce radon below 2.7 pCi/L, include a lifetime warranty, and verify the result with post-install testing.

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

Radon solutions for Denver’s varied housing stock

Denver includes early twentieth-century bungalows, brick ranches, postwar subdivisions, remodeled basements, townhomes, and new infill construction. Older houses may have multiple slab pours or additions, while newer homes can have tightly sealed envelopes that make controlled soil-gas venting especially important.

Our design may use a sealed sump lid, one or more sub-slab suction points, crawlspace membrane, or an attic-routed fan. The correct combination depends on how air moves beneath the home and where piping can be installed safely and discreetly.

What matters locally

Planning for Denver foundations

Local housing patterns inform the inspection, but the final design always follows the conditions at your property.

Older foundations

Historic homes and additions can create separate soil zones that require careful pressure-field testing.

Finished basements

We plan suction and pipe routing around living spaces, utilities, and existing finishes.

Dense neighborhoods

Exterior components are positioned for code-compliant clearances and a clean street-facing appearance.

Simple from start to finish

Questions answered

Radon mitigation FAQ for Denver

Get direct answers about testing, installation, pricing, guarantees, and foundation-specific system design.

How long does radon mitigation take in Denver?

Most residential radon mitigation systems in Denver are installed in one 3–4 hour visit. Homes with multiple foundations, finished basements, or crawlspaces may require additional planning, but we explain the routing and scope before work begins.

What result do you guarantee for Denver homes?

Custom Radon Solutions guarantees post-mitigation levels below 2.7 pCi/L and backs the installed system with a lifetime warranty. A post-install test confirms the system is performing as designed.

How much does radon mitigation cost in Denver?

Pricing depends on the foundation, number of suction zones, pipe route, crawlspace conditions, and fan requirements. We provide a free in-person estimate so you receive a system-specific price instead of a generic range that may not fit your home.

Do you provide a free radon test kit in Denver?

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.

Is radon common in Denver?

Yes. Colorado is considered a high-radon state, and Denver-area homes can have elevated levels in any neighborhood and at any age or price point. Testing is recommended because soil conditions and entry paths vary from one property to the next.

Can you mitigate a finished Denver basement?

Yes. We regularly design systems for finished basements. The site visit helps us choose a suction location and pipe route that reach the soil while minimizing disruption to finished rooms.
