Q: Do air purifiers help with radon?

• <div><p>No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.</p></div>

Q: How does radon enter my home?

• <div><p>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.</p></div>

Q: What is the biggest source of radon?

• <div><p>The soil beneath your house is most likely what&rsquo;s causing an increased level of radon. This is because soil holds radioactivity for a long time and it&rsquo;s also what most buildings are built on. Another common source of radon is water from a source that hasn&rsquo;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.</p></div>

Q: How much does a radon mitigation system cost?

• <div><p>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.</p></div>

Q: What types of radon mitigation systems are available?

• <div><p>Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.</p></div>

"Our radon specialist, Tim Milledge, was terrific. Communication was excellent, he arrived on time, was professional, courteous and experienced. He was able to run the pipe line and place the other equipment in a way to be unobtrusive and did nothing to detract from the aesthetics of our property. He explained post procedures and cleaned up after himself, unusual these days with service providers, and completed the installation quickly and efficiently. We would highly recommend SWAT and, in particular Tim."
