Radon Mitigation
How is Radon Mitigated?
The most common and most effective methods of reducing radon levels in a home or building are active sub-slab depressurization (ASD), and active drain tile depressurization (ADD) systems.
Radon is mitigated by installing a system that pulls the radon gas out from beneath the foundation and affected soil and exhausts it outside of your property, far enough away from windows and other openings so that the gas will not re-enter the building.
A reduction system typically consists of PVC pipe connected to the soil either through a drilled hole in your lowest level concrete slab, via a sump lid connection, or access beneath a plastic sheet in a crawl space. Attached to that pipe is a continuously operating fan outside of the property that quietly discharges the radon gas outdoors.
How this system is installed and works is dependent of the construction of the home, rather than the radon concentrations that are present. A home with more than one foundation can present challenges in collecting the soil's radon gas from under all portions of the building, however, talented mitigation contractors can typically connect multiple systems together so that only one fan is required for the entire system.
Because the use of a high-density plastic sheet is needed for crawlspace foundations, crawlspace systems can be slightly more costly. The system and plastic will encapsulate the soil as well as seal the walls and then route the piping to the exterior fan. However, there is a great benefit to reducing moisture in the crawlspace while also lowering the radon levels in your home!
My home has tested high for radon, now what do I do?
If you have confirmed that your home has elevated radon levels of 4 pico curies per liter (pCi/L) or higher, you should complete the following:
- Select a qualified radon mitigation contractor such as Radon Pros to reduce the radon levels in your home.
- Radon Pros will help determine an appropriate radon reduction method.
- Install custom designed radon reduction system.
- Perform post mitigation testing to verify the radon levels have been effectively reduced.
- Maintain your radon reduction system and inspect the system monitor periodically.
If I want to purchase a home with a radon problem, should I consider finding a different home?
If a properly performed test indicates an elevated level of radon in the home you wish to purchase, it is highly possible other homes in the same area will have elevated radon as well. Good news for you though! Radon can be reduced, either before you buy the home, or after your purchase and move in.

Active sub-slab depressurization is a technique used to collect and remove radon from beneath the concrete floor/slab in the lowest levels of the home. This is done by drilling a suction point (a hole that is typically 4-inches in diameter) through the floor slab and installing a 4-inch diameter schedule 40 PVC pipe into the suction point. This piping is then run from the suction point to the exterior of the home.
A vent fan is placed in-line with the piping on the exterior of the home (or in the attic) to create negative air pressure under the floor slab. The radon and other soil gases are then drawn from beneath the slab and into the system's piping where they can be vented safely outside. In many cases, this piping can be run through the home (garage, closet, attic, etc.) and roof to help conceal the system.

When a home has a drain tile waterproofing system around the foundation, the drain tile can facilitate collection of the soil gases, while at the same time functioning as a waterproofing system. The sump pit is covered to create an airtight seal, with the sump pump (if present) being routed through the cover. A hole (suction point) is drilled through the sump pit cover or the concrete slab to access the drain tile/sump pit, and four-inch diameter schedule 40 PVC pipe is placed into the hole, and travels from the suction point to the exterior of the home.
