Doan, LLC

Doan, LLC brings a 4.9-star rating from 108 Google reviews to Detroit's mold challenges, and that track record matters in a city where high humidity (70% average) and substantial rainfall (33" annually) create ideal conditions for mold growth. Most Detroit homes were built around 1950, meaning older construction that's especially vulnerable to moisture problems. When you're dealing with mold in a climate like ours, you want a contractor who's proven they can handle it, and those reviews suggest Doan, LLC knows what they're doing.

Michigan doesn't require a specific mold remediation license, so before you hire anyone, verify they hold IICRC S520 certification and confirm they carry both general liability and pollution liability insurance. These credentials and policies protect you if something goes wrong during the work. Typical remediation projects in the Detroit area run between $1,200 and $3,800, so get a detailed estimate upfront and don't skip the insurance verification step.
