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: Can I use my sump pit for radon mitigation?

• <div><p>If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.</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>
