Mold Remediation Cost in Illinois
Mold remediation in the Metro East typically runs $1,500 to $6,000 for a contained area such as a bathroom or a section of basement, and $10,000 to $30,000 or more for whole-home or structural work. We do not perform remediation — this page exists so you can judge a contractor quote properly.
| Service | Typical cost | Notes |
|---|---|---|
| Small contained area (under 10 sq ft) | $500 – $1,500 | Often manageable as a DIY clean-up |
| Bathroom or single room | $1,500 – $3,500 | Containment plus material removal |
| Basement section | $2,500 – $6,000 | Depends on finished versus unfinished |
| Crawl space encapsulation and treatment | $5,000 – $15,000 | Includes vapour barrier |
| Attic remediation | $2,000 – $7,000 | Usually plus ventilation correction |
| Whole-home or structural | $10,000 – $30,000+ | Rare, and worth a second opinion |
A quote that does not identify and price fixing the water source is incomplete. Remediation without a moisture fix simply resets the clock.

Common questions
Do you charge for a quote?
No. Phone consultations are free, and if we do not think you need an inspection we will tell you so on the call.
What decides where I land in the range?
Four things: the square footage and number of levels, whether there is a crawl space needing access, how many laboratory samples the situation actually warrants, and whether you need same-week turnaround. We confirm the exact figure before we book, not after we arrive.
Is there a travel charge for my town?
No. Every town in our service area is charged at the same rate, from Edwardsville to Vandalia.
Can I get just the lab work without an inspection?
We do not recommend it. Samples taken without moisture mapping and an outdoor control produce numbers nobody can interpret, which is the most common way people waste money on mold testing.

We test, document and verify. We never sell remediation, so we have no reason to find a problem you do not have.
