Frequently Asked Questions

How much does radon mitigation cost in Chicago?

Radon mitigation typically costs $800-$2,500 for a standard sub-slab depressurization system. Costs vary based on home size, foundation type, and system complexity. Contact contractors in Chicago for a specific quote.

What radon level requires mitigation in Chicago?

The EPA recommends mitigation for radon levels at or above 4 pCi/L. Levels between 2-4 pCi/L should also be considered for mitigation. Any Chicago home can have elevated radon regardless of age or construction type -- testing is the only way to know.

How long does radon mitigation take in Chicago?

Most radon mitigation systems are installed in a single day (4-8 hours). Post-installation testing takes 2-7 days to confirm the system is reducing radon to safe levels. The entire process from testing to verified mitigation is typically 1-2 weeks.
