Radon Detection and Reduction questions, answered by experts

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.

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.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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 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.
