"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."

"Mike Smith, The Mold Hunter, Inc., was an extremely easy and professional mold remediation company to work with. Mike was prompt with communications throughout the process, answered all our questions and gave detailed explanations of what was going to be done from testing to remediation, and he provided a detailed and accurate estimate of the cost. His employees were very thorough, competent, and respectful of our property. Mike even gave suggestions as to how we could do some preparation ourselves in order to save money. What more could you ask? We highly recommend Mike for testing and mold remediation."

"A two-man team worked very efficiently to remove each vent cover and vacuum inside the vent openings throughout the townhouse. One man removed the vent covers while the other man vacuumed inside the vent openings. No problems with how they worked but I think there are other companies who perform a more thorough cleaning of ductwork using other methods. This company did a superficial cleaning and worked very quickly. In and out within an hour.

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.
