How to Check for Air Leaks That Could Raise Radon Levels
Radon is a silent, odorless gas that can seep into your home through the smallest cracks and gaps — often unnoticed until it’s too late. Even if you already have a radon mitigation system in place, air leaks in your home’s foundation or basement can allow radon to re-enter, reducing the effectiveness of your system. Regularly checking for air leaks is a simple yet powerful way to keep your indoor air safe and your mitigation system working efficiently.
Here’s how to identify potential problem areas:
Inspect the sump pump and pit cover.
Make sure your sump pump lid is tightly sealed. If it’s loose, cracked, or missing a gasket, it can become a major entry point for radon gas.
Look for cracks in concrete floors and foundation walls.
Over time, small cracks can widen and create new pathways for radon. Seal them with high-quality polyurethane caulk or epoxy for a long-lasting fix.
Check around plumbing and electrical penetrations.
Gaps around pipes, wires, or utility lines entering your basement should be properly sealed with expanding foam or silicone sealant to prevent radon infiltration.
Inspect crawl spaces and floor drains.
Unsealed crawl space floors or open drains can allow radon to flow freely into your living areas. Consider installing vapor barriers or drain seals as part of your mitigation strategy.
Test your radon levels regularly.
Even small air leaks can cause radon levels to fluctuate. Conducting annual radon tests helps ensure your home stays within safe limits.
