"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."

Radon Detection and Reduction questions, answered by experts

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

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

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