"Called super quick to set up a testing date, had an opening fast! Arrived early to the appointment, gave a nice heads up text, "be there in 15 minutes." Polite and respectful, kind, informative and very knowledgeable, super patient with my millions of questions. High integrity, informed me of a couple of simple cheap DIY repairs in my basement that would be beneficial to make the radon system last longer when he didn't have to. Gave quote and timing of project right there and then, no waiting. Highly recommend this company!"

Radon Detection and Reduction questions, answered by experts

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.

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.

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.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.
