Radon Remediation in Existing Buildings
What to Do
What to Do
Buildings with high radon levels require some change in the mechanical systems or in the operation of the building. You should choose a licensed radon mitigation contractor to design and install your system.
The EPA booklet "Consumer's Guide to Radon Reduction" describes the basics of radon remediation in existing structures.
A sealed sump pump lid is key in radon protection. If you have a basement footing drain system with a sump pump see our page about sump pumps and radon.
