"Our radon specialist, Tim Milledge, was terrific. Communication was excellent, he arrived on time, was professional, courteous and experienced. He was able to run the pipe line and place the other equipment in a way to be unobtrusive and did nothing to detract from the aesthetics of our property. He explained post procedures and cleaned up after himself, unusual these days with service providers, and completed the installation quickly and efficiently. We would highly recommend SWAT and, in particular Tim."

Radon Detection and Reduction questions, answered by experts

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
