Customers say: True professional

"Jeff and his folks were a pleasure to work with. His communication regarding any delays or other issues is excellent. He is also great at answering followup questions that I have about how the system is running. It took our radon readings down to nearly zero from an alarmingly high value. We were hovering below 4 pCi for many years, but then our crawlspace was sealed and insulated and it soared in the living space. (The crawlspace itself was 20 pCi). Highly recommend."

"We recently bought a house and knew we needed some basement waterproofing. We went to Sure Dri because of the Angie's List reviews. And Keith Martin and his staff were great! Keith was very responsive if I had any concerns or questions. He walked me through the process and seemed to genuinely want to make sure what my options were before deciding on an interior French drain. His staff were very fast & professional (& kept the work area super clean). They even cemented an old drain to secure it and move the new sump pump to a new location with no extra charge. He guarantees his work and I highly recommend Sure Dri."

Radon Detection and Reduction questions, answered by experts

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.
