"Hired for the convienience of their timely ability to install a radon system. The vent on the outside of the house is a large diameter, circular chimney that is very unsightly. Prices were a bit higher than other companies, but their ability to install quickly took precedence. In SWATs defense, I did not inform the company of my displeasure as the system was being installed as a condition of sale."

Radon Detection and Reduction FAQs, answered by experts

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

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

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