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: How long does the radon abatement process usually take?

• <div><p>Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.</p></div>

Q: What would cause radon in a house?

• <div><p>The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.</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: Can you remediate radon yourself?

• <div><p>There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.</p></div>
