It seeps into homes from the soil beneath, making its way through cracks in the foundation or gaps around service pipes. Since radon is colorless and odorless, it can be difficult to detect without the use of specialized equipment.
Testing your home for radon is a critical step during a renovation. Home testing kits are readily available and easy to use, but they must be left in place for a certain period and then sent to a laboratory for analysis. If you discover high radon levels, it’s advisable to engage a certified radon mitigation professional.
Radon reduction techniques can include sealing cracks in the foundation, increasing ventilation, and installing a radon reduction system. This system involves piping and a fan to redirect the radon from your home to the outside. Remember, dealing with radon is not a do-it-yourself task and should always be handled by professionals to ensure the safety and health of your household.
