Q: How much electricity does a radon mitigation system use?

• <div><p>The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from <b>$30 to $300 per year</b>, again depending on the size of the fan.</p></div>

Q: Is a radon mitigation system expensive to run?

• <div><p>The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.</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 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: 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>

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."
