"Had them come out to install a Radon Mitigation Fan. Service was fast and the installer was extremely knowledgable. He was in an out within an hour and the radon dropped from a 4 to a 0.59! Extremely happy with the result. Price wasn't cheap by any means but definitely fixed our problem."

"Once they started working on it, the work was great. What they did was good, but they forgot to put caulking on one of our skylights. They came back quickly to fix it. We put half the money down and then we didn’t hear anything for 4 months. I guess they were switching company owners, but since then it has been good."

Radon Detection and Reduction questions, answered by experts

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.

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.

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).

Installation typically takes 1-2 days, depending on the system and property layout.

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.
