"RADON SYSTEM WAS NOT WORKING. (Installed by another company years ago). The phone contact was pleasant and efficient. The Technician came on the agreed day and the agreed time: he explained what was wrong, explained the options, then repaired the system so it is working better than it did when first installed."

"They installed a Radon Mitigation system in a house I was selling. They had the best price, the experience I wanted, and were able to install a few days after I called. Technician was very nice and efficient in getting it installed. Good warranty too. I had my system installed in an encapsulated crawl space."

Customers say: True professional

"Jeremy was very professional and did a great job. He had reached out after I scheduled the original appointment to reschedule due to poor weather conditions. He offered to move the appointment to a date/time that he usually doesn t work to accomodate my needs. Once he had finished his work, he walked my fiance and I through everything explained it all very clearly. He also thoroughly explained the process for testing radon levels and getting test results back after the mitigation installation was complete. Would definitely recommend his services as he did a great job and his quote was very competitive."

"They did a great job with the installation and made sure the Radon was under the level it needed to be. He had to make a couple of trips to make that happen but was very polite and profession through the whole process."

Radon Detection and Reduction questions, answered by experts

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

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.

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.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.
