Why Crawl Space Radon Mitigation is Necessary in Lexington

Radon exposure is not limited to basements or slab foundations. It commonly affects homes with crawl spaces, making mitigation necessary for these structures. The mitigation system can be used regardless of whether the home has a crawl space, slab, or basement structure.

Crawl Space Radon Mitigation Process in Lexington, KY

Kentucky requires that all contractors performing radon-related services be licensed by the state. Mitigation is recommended when testing shows radon levels are at or above 4.0 pCi/L. The state radon office provides verification information for certified professionals.

Understanding Radon System Costs and Energy Use

While the initial system cost varies by home, the operation of the radon fan adds to energy usage. An active fan draws 100 to 300 watts continuously. This operation can add approximately $30 to $300 per year to the home's energy bill.

State Requirements for Radon Professionals

Contractors must be certified by the state to perform radon mitigation work. Kentucky mandates that radon-related services are performed by licensed professionals. You can verify certifications through the state radon office.
