Many Bloomington homeowners assume any contractor can handle mold work, but Indiana doesn't require specific mold remediation licensing. That means you need to do the vetting yourself. Before hiring anyone, including Hays + Sons, verify they carry general liability insurance and follow IICRC S520 standards - these are the actual safeguards that separate qualified work from costly mistakes. Given Bloomington's climate (70% humidity and 48 inches of rain annually), mold is a real concern, especially in older homes like the median house built in 1983.
When you're ready to get quotes, know that a typical remediation project in this area runs between $1100 and $3550, so you'll have a ballpark before talking to anyone. Hays + Sons has earned a 4.9-star rating across 83 Google reviews, which suggests they're doing something right for Bloomington residents. Before you sign any agreement, ask to see proof of their insurance and confirm in writing that they'll follow IICRC standards for the work.
