"Absolutely amazing experience. My home radon levels were averaging 5.0 pCi/L. Two days after Edward and his team finished the mitigation job the levels went down to 0.3. Incredible result. I can’t be happier."

"He was friendly, very professional, and answered all my questions clearly about how mold happens in a home. His reasonable estimate and scope of work. What are the steps for mold remediation? Furthermore, I had delicate items around the work area. He was very successful in making sure that nothing was damaged. "Think floor demolition in a China shop" where none of the dishes gets broken. I highly recommend restoration Hunter if you have to deal with mold in the home."

Radon Detection and Reduction questions, answered by experts

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’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.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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.

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.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.
