Boulder County’s Front Range geology is well known for elevated radon potential, but risk cannot be judged by neighborhood, slope, or home value. Radon may accumulate in older basements, slab-on-grade additions, garden-level rooms, and tightly sealed high-performance homes. Testing provides the only property-specific answer.
We design active soil depressurization systems that account for Boulder’s varied architecture and the homeowner’s preference for a low-profile finished appearance. Every estimate includes a foundation review, suction-point strategy, fan and discharge location, and discussion of how the system will be monitored.
Most systems are installed in one 3–4 hour visit. Our work is guaranteed to reduce radon below 2.7 pCi/L and is protected by a lifetime warranty, with post-install testing used to verify performance.
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
Careful mitigation for Boulder homes and remodels
Boulder housing ranges from 1950s ranches and foothill homes to major remodels, accessory dwelling units, and modern energy-efficient construction. Additions often create more than one foundation zone, while mechanical and solar equipment can influence the cleanest route to the roofline.
We focus on pressure-field coverage beneath the home, durable sealing at accessible openings, and code-conscious vent termination. The result is a system designed for the building rather than an oversized fan used to compensate for incomplete planning.
What matters locally
Planning for Boulder foundations
Local housing patterns inform the inspection, but the final design always follows the conditions at your property.
Variable geology
Front Range soils can produce elevated radon, and concentrations may differ substantially between adjacent homes.
Remodeled footprints
Additions and mixed foundations are evaluated as separate pressure zones when needed.
Design sensitivity
Interior, attic, and discreet exterior routes are considered to protect the home’s appearance.

Questions answered
Radon mitigation FAQ for Boulder
Get direct answers about testing, installation, pricing, guarantees, and foundation-specific system design.
How long does radon mitigation take in Boulder?
Most residential radon mitigation systems in Boulder 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 Boulder 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 Boulder?
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 Boulder?
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 a concern in Boulder County?
Yes. Boulder County is in a region with significant radon potential. Homes of every style can test high, so testing is recommended even when a neighboring property reported a low result.
Can you hide the radon fan in an attic?
An attic-routed system is possible in many homes when there is a safe pipe path and compliant exhaust location. The fan must remain outside conditioned living space, and we determine feasibility during the estimate.
