Sub-slab depressurization is a method used to keep radon gas from seeping into basements by creating a vacuum beneath the concrete floor. A fan system pulls air from below the slab and vents it safely outside, which reduces the pressure difference that draws radon upward. It's a common fix in homes with high radon levels, typically installed by contractors who drill a small hole and set up piping. The system runs quietly and continuously, making it a practical solution for improving indoor air…

Radon levels in Illinois vary significantly by region, with many homes in the northern and central parts of the state testing above the EPA's recommended action level due to underlying geology. Testing your home is the only way to know if elevated levels are present, as radon is an invisible, odorless gas. Winter is an ideal time to test because windows are typically closed, leading to more accurate results. Consider a charcoal canister test or a continuous monitor for reliable data.
