Centennial homes often combine large finished basements, multiple wings, attached garages, and landscaped lots. Those features make system planning important: the goal is to establish reliable suction beneath the occupied foundation while choosing a pipe route that respects finished space and the exterior design.
Custom Radon Solutions begins with a free in-person estimate. We review the radon result, foundation plan, sump and utility locations, additions, and practical fan placement. The proposal then defines a complete system rather than leaving routing decisions until installation day.
Most residential systems are completed in 3–4 hours. We guarantee post-mitigation levels below 2.7 pCi/L and include a lifetime warranty for lasting confidence.
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
Low-profile mitigation for Centennial homes
Centennial includes 1970s and 1980s subdivisions, custom homes, newer communities, townhomes, and properties with partial crawlspaces. Larger footprints and finished lower levels can require more diagnostic planning than a compact single-slab home.
We prioritize clean equipment placement, effective sealing, and fan sizing based on the home. Attic or garage routing may be considered where practical, while exterior routes are placed away from primary elevations whenever conditions allow.
What matters locally
Planning for Centennial foundations
Local housing patterns inform the inspection, but the final design always follows the conditions at your property.
Finished basements
Suction points and piping are planned to minimize disruption to high-use lower-level rooms.
Larger footprints
We evaluate whether separated slab zones communicate before finalizing system design.
Appearance-conscious routing
Garage, attic, and less-visible exterior paths are considered where they remain safe and effective.

Questions answered
Radon mitigation FAQ for Centennial
Get direct answers about testing, installation, pricing, guarantees, and foundation-specific system design.
How long does radon mitigation take in Centennial?
Most residential radon mitigation systems in Centennial 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 Centennial 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 Centennial?
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 Centennial?
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.
Can radon piping run through an attached garage?
In some homes, a garage route provides a clean path while keeping the fan outside conditioned living space. We verify fire separation, access, exhaust placement, and code requirements before recommending it.
Do large Centennial homes need multiple fans?
Not automatically. We first determine whether foundation areas communicate beneath the slab. A well-designed single-fan system may serve multiple suction points, while truly separated zones may require another solution.
