The Role of Sealing in Radon Mitigation
The EPA mandates that all openings around radon vent pipe penetrations in slabs, foundation walls, or crawlspace membranes must be sealed. This sealing must be done in a permanent airtight manner. Sealing is a required component of any professional radon mitigation system.
Sub-Slab Depressurization Costs in Lexington
Sub-slab depressurization is the most common mitigation system used in most cases. Professional installation typically costs between $800 and $2,500, and can reduce radon by up to 99%. A national cost guide places the average mitigation system cost between $1,200 and $3,000.
Energy Costs and New Construction Options
A radon fan can add $30 to $300 per year to a home’s energy bill due to continuous operation. For new construction, the basic pipe penetration can be done for about $300 before a fan is added later if needed.
Understanding Radon Risk Levels
The EPA identifies radon as a health risk and sets the action level at 4 pCi/L. Mitigation is recommended when levels reach this threshold. The University of Kentucky extension notes that sub-slab depressurization is the standard approach for most homes.
Verifying Professional Credentials
Contractors performing radon-related services in Kentucky must be licensed by the state. You can verify state radon work through the state radon office at radon.ky.gov. This ensures the pros we refer meet state requirements.
What to do next
- Test your home for radon to determine if mitigation is needed, as the EPA recommends action at 4 pCi/L.
- Verify that any contractor is licensed by the state and check the state radon office website at radon.ky.gov.
- Ask for a quote that details the specific fan's energy draw, as it can add $30 to $300 annually to your bill.
- Confirm the contractor is an NRPP-certified Radon Mitigation Specialist before proceeding with installation.
