What makes the price go up or down?

The Lexington contractor guidance adds that location, square footage, foundation type, and radon gas level all affect the final price. Ask your contractor to explain how each factor applies to your home.

How much does mitigation cost for a multifamily building?

The University of Kentucky landlord guide estimates mitigation at $2,500 to $4,000 for multifamily housing. Single-family homes are estimated at $1,500 to $3,000 in the same guide. Use these figures as planning ranges, not fixed quotes.

Does building radon-resistant features into a new home save money?

The University of Kentucky booklet puts a radon-resistant new construction system at approximately $600 to $800 for a single-family home. EPA notes that including passive radon-resistant features during construction usually costs less than fixing the home later. Ask your builder whether these features are included.

When should I consider an active system?

EPA advises that if a home tests at 4 pCi/L or more, a qualified mitigator should estimate the cost of upgrading to an active system. The University of Kentucky booklet says converting a passive vent system to an active fan-powered system averages $500 to $600. Have the contractor test first before committing to upgrades.

What to do next

Test your home first, and confirm the level is 4 pCi/L or higher before pricing an active system.
Verify your contractor's certification on the Kentucky certified radon professionals roster, and check for NRPP or NRSB credentials.
Confirm the roster lists people who have passed a national competency exam and complete continuing education.
Ask for a written quote that states the system type, the home's square footage, and the foundation type.
