In the United States, less than 10% of the homes with radon will have an issue that requires mitigation. Despite what you may have heard, most (if not all) of the affected homes can have that issue resolved fairly quickly and affordably.
Fixing a radon issue can be as simple as adding caulk to foundation cracks in a basement. For some homeowners, that simple step can lower the radon to a safe level. Even homes that require a mitigation system can rest assured that the problem has a solution.
One common remedy for elevated radon uses a pipe that is gas-tight to vent the gas from the crawlspace area to above the roof. Another popular method is to vacuum air from the basement out of the attic into the atmosphere above your home. In other words, there is always a solution to the radon problem – you just need to find the right mitigation company to partner with.
