Midwest Aerobiology Labs (Mold & Asbestos Inspectors)

Midwest Aerobiology Labs holds a 4.9-star rating across 209 Google reviews, which matters in Chicago where older homes (median built 1956) and humid conditions (71% average relative humidity, 37" annual rainfall) create ideal conditions for mold growth. That track record suggests the inspectors know what they're looking for in the local housing stock. A standalone mold inspection typically costs $200-$600 in this region, so you're evaluating both quality and price when you call.

Before hiring, verify that Midwest Aerobiology Labs is truly a mold inspector only, not a company that also performs remediation work. Inspectors who do both create a conflict of interest under industry standards. Illinois doesn't require a specific mold remediation license, but reputable inspectors hold IICRC S520 certification and carry general liability insurance. Ask to see these credentials independently. One important caveat: if the inspector recommends remediation work, get a second opinion from an unaffiliated contractor before proceeding.
