Cost to Mold Remediation in Chicago, IL (2026)
If you’re budgeting a mold remediation in Chicago, most projects run $610-$7,320, 22% above the $2,500 national average. What moves that number most is usually one thing: Mold Type and Toxicity. On its own it can swing the cost by $500-$5,000 premium for black mold (Stachybotrys), so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Test before you treat. A professional mold inspection ($200-$600) can confirm whether you have a large mold problem or surface condensation that looks like mold. This $300 investment prevents spending $3,000 unnecessarily.
In the Midwest (where Chicago sits): Most affordable labor rates; basement mold is common due to hydrostatic pressure.
