What does the fix usually involve?
The most common method is sub-slab depressurization. A pipe and fan draw radon from beneath the foundation before it can enter the house. An existing home can often be fixed for about the same cost as other common home repairs.
How do I know the fix worked?
Run the system with the fan on for at least 24 hours, then retest within 30 days of installation. EPA recommends a 2- to 7-day measurement to check initial effectiveness. Retest every home after mitigation and at least every two years.
How do I verify a contractor is certified?
Kentucky law bars anyone from conducting radon mitigation without the appropriate certification. Contractors must maintain certification through a board-approved proficiency program. Ask the pro for proof of licence and insurance before work starts.
