"A small testing device was set up in our basement and was left in place three days. The device was then picked up and we received a phone call a day later informing us of the radon level detected. This was followed up by a professionally prepared report mailed to us detailing the results and how to interpret them."

"JC Radon Solutions did a great job in the installation of our radon mitigation system. They arrived at the agreed time for both the proposal visit and then for the install work. The work area was kept clean during the install. A great job by a great company. I highly recommend JC Radon Solutions for radon mitigation work. Prior to the mitigation work, radon monitoring recorded average readings of 10. Now the readings are 3.5. Very pleased with the JC Radon Solutions system."

Customers say: Quality work

"We were very happy with the crew who worked in our home. Very professional. Prepared the site so we could not tell they had even been in our home. Testing following the job indicated that the radon gas was leaving our home. Our radon level went from 12 to 0."

"Schan did a great job, very professional. He came out to see what the job was before he gave me a quote. I have a huge crawl space which took some time but he stuck with it to finish it in one day. Now I can breathe easier knowing it's taking care of right. I highly recommend Clean Air Radon Systems."

"Mike from Us Waterproofing came out to give me an estimate on repairing a foundation crack, which over time caused seepage into my lower family room, resulting in mold behind the drywall.  He explained a process that could be done from the outside to seal the crack, instead of cutting out the wall.  The following week a hole was dug down to the foundation, filled with clay powder, and the crack above the soil was sealed with something like tar.  With rain the clay powder hardens and seals the crack.  I tested using a garden hose and it worked! No water leaking into the family room.  US Waterproofing quickly fixed my issue and it is warranted for life.

Radon Detection and Reduction questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

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