This homeowner decided to test the Radon levels in the air within their home and discovered they were at 4.7 pCi/L. This metric system helps to identify the levels of Radon gas in the air and when you are at risk. The Environmental Protection Agency recommends that if the Radon levels are above 4.0, then a mitigation system is necessary. This level is equivalent to smoking 8 cigarettes a day. Radon is a naturally occurring radioactive gas from the soil of the earth that is incredibly harmful to breathe in. It has been proven to be the leading cause of lung cancer in nonsmokers. At John's Waterproofing, we offer Radon mitigation systems that pull the gas out of the soil and pushes it out towards the atmosphere. This helps prevent those living in the home from breathing the gas in and being put at risk.

In the Pacific Northwest Radon is a huge concern. It is a naturally occurring radioactive gas that comes from the soil beneath our homes. Over time, uranium and radium break down in the soil and that is what releases the Radon gas. Luckily, at John's Waterproofing we offer testing kits and mitigation systems so that homeowners are protected from constantly breathing in Radon gas. According to the EPA, it is recommended to get a mitigation system if the PCI level is over 4.0. This level of Radon is equivalent to smoking 8 cigarettes a day and is the leading cause of lung cancer in nonsmokers. But how does the mitigation system work? We start by drilling a hole in the lowest point of the home so that a PVC pipe can reach 2 feet down into the soil. This pipe then connects to a fan that gets installed outside the home to pull out Radon gas from the soil. It can then release the gas up into the atmosphere above the house so that its occupants aren't at risk of inhaling it. Radon is able to get into the home through cracks or breaks in the foundation and that is why having the Radon mitigation system working to pull the gas out of the soil underneath your home is so important.
