"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 FAQs, answered by experts

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.

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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
