At this property in Cortez, Colorado, elevated results from a professional radon inspection and radon test indicated the need for an engineered Active Sub-Slab Depressurization (ASD) system. Due to the length and layout of the home, it was initially anticipated that two separate radon mitigation systems might be required to effectively reduce indoor radon levels. Our team installed a primary sub-slab suction point within a bedroom closet, carefully routing the mitigation piping up into an exterior storage room and venting safely through the storage room roof to discharge radon gas above the home in accordance with EPA radon mitigation standards. During installation, we drilled through the concrete slab and discovered large rock fill beneath the foundation — part of a passive solar heating design — which actually enhanced sub-slab air movement and depressurization efficiency. Post-mitigation radon testing confirmed that the single ASD system successfully reduced radon concentrations throughout the entire home, eliminating the need for a second penetration and providing long-term indoor air quality protection for this Cortez, CO residence.
No. In fact, newer homes can sometimes have higher radon levels because modern construction is more airtight. Radon comes from the soil beneath your home — not from the age of the house.
Yes. A mitigation system is often seen as a proactive improvement and can simplify future real estate transactions by eliminating radon concerns during inspections.
Radon is invisible and odorless — there’s no way to detect it without testing. Even homes next door to each other can have completely different radon levels. The only way to know is to test.
Most professional tests run for 48 hours to ensure accurate results. After testing, we review the findings with you and explain exactly what they mean for your home.
Most mitigation systems are installed in a single day. You can remain in your home during installation.
No. Modern mitigation systems are quiet and discreet. The vent stack is typically placed along the exterior of the home, and the fan operates with minimal noise.
Radon is the second leading cause of lung cancer in the United States and the #1 cause among non-smokers. Long-term exposure increases risk — which is why early detection matters.
Costs vary depending on your home’s layout and foundation type. After testing and evaluation, we provide transparent pricing before any work begins.
If radon levels exceed EPA recommendations (4.0 pCi/L), we design a mitigation system tailored to your home’s structure. Most systems reduce radon levels by up to 99%.
