A professionally installed mitigation system will reduce radon levels in your home by up to 99% — permanently.
Radon mitigation uses sub-slab depressurization (SSD) — a vent pipe and fan installed beneath your slab that draws radon from the soil and routes it safely above the roofline before it can enter your living space.
Most systems reduce radon by 90–99% and are installed in a single day.

Each installation is designed specifically for your home's foundation type and soil conditions.
A hole is drilled through your concrete slab, creating direct access to the soil and aggregate beneath. This is where radon is captured before it enters your living space.
A sealed pipe routes captured radon from the suction point, up through or along the exterior of your home, and terminates safely above the roofline — well away from windows and doors.
A continuously running, energy-efficient fan maintains constant negative pressure beneath the slab. Most fans are nearly silent and consume minimal electricity — similar to a light bulb.
Visible cracks, gaps around pipes, and sump openings are sealed with appropriate materials to prevent radon from bypassing the system and entering through secondary paths.
A visual pressure indicator (U-tube manometer) is installed on the pipe so you — and future home inspectors — can confirm the system is functioning correctly at a glance.
After installation, we place a test device to verify actual radon reduction. We confirm results meet EPA guidelines before the job is considered complete.
Results vary based on foundation type, soil permeability, and initial radon levels. We test after every install to confirm results.
Most installations are completed in a single day with minimal disruption to your household.
We walk through the basement or crawlspace to determine the optimal suction point location, pipe routing path, and fan placement.
We drill a 4" core through the slab at the determined location, seal cracks and gaps, and prepare the pipe routing path.
The PVC vent pipe is installed through or along the exterior wall and routed to above the roofline. The fan unit is secured and connected.
We confirm the system is operating correctly using a manometer, then place a post-installation radon test device. We review everything with you before leaving.
