Our Radon Mitigation Process

01

Radon Testing

If you don't have recent test results, we conduct or recommend short-term (48-hour) or long-term testing before and after mitigation.

02

Diagnostic Testing

We perform suction/pressure field extension tests to determine the best system placement and pipe routing.

03

System Installation

A PVC pipe is installed through the floor slab (or membrane) and connected to a continuously running fan that draws radon from beneath the home and exhausts it above the roofline.

04

Post-Mitigation Test

A follow-up radon test confirms the system is achieving adequate reduction — typically to below 2.0 pCi/L.

Radon Mitigation FAQ for Philadelphia Homeowners

How often should Philadelphia homeowners get radon mitigation?
Given Philadelphia's cold winters with freeze-thaw cycles damaging mortar, most homeowners benefit from radon mitigation at least once a year. Winter ice dam and mortar damage often makes spring or fall the optimal time to schedule service.
What home types in Philadelphia most need radon mitigation?
Red brick rowhouses (very common) and Twin and semi-detached homes are the most common home types in Philadelphia and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
What radon level requires mitigation?
The EPA recommends mitigation at levels of 4 pCi/L or higher. Consider mitigation at 2–4 pCi/L as there is no truly safe level of radon exposure.
How much does radon mitigation cost?
Most residential mitigation systems cost $800–$2,500 installed, depending on house construction and foundation type. This one-time cost provides lifetime protection.
How does a radon mitigation system work?
Sub-slab depressurization (SSD) is the most common method — a fan creates negative pressure beneath the slab that draws radon away from the home before it can enter, exhausting it harmlessly above the roofline.
Will a mitigation system affect my heating and cooling bills?
Sub-slab depressurization removes a small amount of air from beneath the slab, not from inside the home. The impact on energy costs is negligible.
