When you're buying or selling a home, a radon test is a quiet but crucial step. That invisible gas can seep from the ground into basements, and since you can't see or smell it, a simple test kit or professional check gives you real peace of mind. It's just a small canister sitting in the lowest lived-in area for a few days, then off to a lab. The results can affect your negotiation or prompt mitigation, but mostly it's about knowing your air is safe to breathe.
