"The company rep collected site samples quickly ... in and out in about 20 minutes. And, the company turned the report around in two days. The service was a pricy, mostly due to the fixed call-out fee. The cost per sample was higher than one other instance that I know of but not unreasonable."

Radon Detection and Reduction questions, answered by experts

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

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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

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.
