Mitigating The Threat of Radon
What to Expect
How Disruptive Will This Be?
No one wants their home turned upside down. Is reducing radon in my home going to thrown our lives into chaos?
Residential Radon Testing
When Royal Radon designs a mitigation system, the first step is a careful investigation of how radon is getting into your home. A certified technician will walk through the basement or lowest level, looking for typical entry points such as cracks in the slab, control joints, gaps around plumbing and wiring, the perimeter of the sump pit, and cold joints where walls meet the floor. Radon almost always comes from the soil, so the goal is to create a controlled pathway for that soil gas to leave the house safely instead of leaking through random openings. This planning stage also includes checking how your foundation is built (full basement, slab-on-grade, or crawlspace) and deciding where a suction point and vent pipe can be installed with the least visual impact.
Next
The heart of most modern systems is a method called active sub-slab depressurization, which Health Canada and other authorities recognize as the most effective way to reduce radon in existing homes. Royal Radon will typically core a small, neat hole through the concrete floor and hollow out a “suction pit” in the gravel or soil beneath it. This pit becomes the collection point for radon-laden air under the slab. A PVC vent pipe is then connected to that opening and routed up through the house or along the exterior wall to a continuously running, purpose-built radon fan located outside the living space (often in the attic, garage, or on the exterior wall). The fan gently pulls air from under the foundation and exhausts it above the roofline and well away from windows and other openings, so the gas can safely disperse outdoors.
Finally
To make the system efficient, the technician will also seal accessible cracks, gaps, and the lid of the sump pit, so the fan’s suction is focused on the soil rather than drawing air from inside the basement. The system is designed to run 24/7 and is permanent, much like a furnace or HRV—quietly doing its job in the background. A simple gauge (often a small U-shaped tube or digital indicator) is installed on the vent pipe so you can see at a glance that the fan is operating and creating the right pressure under the slab. Once the system is up and running, Royal Radon carries out follow-up testing—ideally long-term monitoring over several months—to confirm that radon levels have dropped and stayed low through different seasons.
For your family, the experience is straightforward: one or two days of installation work in the lowest level of your home, a tidy pipe and fan on the side of the house or tucked out of sight, and then quiet, continuous protection. Royal Radon’s ongoing monitoring and check-ins make sure the system keeps performing as intended, and you’ll receive clear test results and explanations at each stage. The end result is a home where the radon problem is not just “treated” temporarily but managed continuously, so you can breathe easier knowing the invisible risk under your foundation is under control.
