Q: How do I test for radon gas?

• <div><p>Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.</p></div>

Q: How long does radon mitigation take?

• <div><p>Installation typically takes 1-2 days, depending on the system and property layout.</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: What is considered a safe or dangerous level of radon?

• <div><p>No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.</p></div>

I would never recommend this company again. For one thing, we live 90 miles from Rapid and if they didn?t want to come out this far they shouldn?t have taken the job. Secondly, they came in January and said it would be done before we started calving mid March. March came and went and kept...
