Q: What if radon is still high after mitigation?

• <div><p>You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.</p></div>

Q: How do you remove radon from your home?

• <div><p>You can vent radon out of your house sometimes by simply opening a window, but it won&rsquo;t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.</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: Why is radon detection important for residential properties?

• <div><p>Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.</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>

"Radon 1 did a great job. We wanted to have our existing radon mitigation system removed as it was right by our new screened in porch and have a new one installed in different location in our home. The crew removed the old system and installed the new system in an area far from our screened in porch. The installation was done in an expert manner, the crew were respectful of our property, quiet, clean, wore masks and cleaned up after themselves so you would never know they'd been there, all in less than a day. The pricing was competitive, we feel like we got a fair price. I would hire Radon 1 again."
