Radon Detection and Reduction questions, answered by experts

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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

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.
