Radon Contractors in Mount Pleasant, South Carolina
Radon testing and mitigation system installation..
Mount Pleasant is a fast-growing Charleston suburb with premium coastal contractor demand.
Radon is a naturally occurring radioactive gas that seeps into homes through foundation cracks, gaps, and porous concrete. It's the second leading cause of lung cancer after smoking, and the EPA recommends mitigation for any home testing at or above 4 pCi/L. Radon mitigation typically involves installing an active soil depressurization (ASD) system — a vent pipe and fan that draws radon from beneath the foundation slab and exhausts it above the roofline. Professional radon mitigation systems reduce levels by 80–99% and cost a fraction of what most homeowners expect. Testing is inexpensive and should be done in the lowest livable level of the home.
