Elevated radon levels were identified during professional radon testing, requiring a more advanced mitigation strategy due to the home’s foundation design. Our team implemented an Active Sub-Slab Depressurization (ASD) system, the most effective and widely recommended method for long-term radon mitigation in slab-on-grade and basement homes. To properly access the foundation footing and ensure optimal system performance, we excavated a large area alongside the home using specialized equipment to expose the footing and create a proper suction pit beneath the slab. The sub-slab depressurization piping was installed below the footing to capture radon gas at its source, then routed vertically along the exterior wall and terminated near the roof eave for safe above-roof venting in compliance with EPA radon mitigation standards. Post-installation radon measurements confirmed that the system reduced indoor radon concentrations to well below recommended action levels, providing durable, highly effective indoor air quality protection for this Durango, CO home.
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%.
