Bio Star Services

Bio Star Services carries a 4.8-star rating across 115 Google reviews, which matters in Flint where older homes and the region's damp climate create real mold risk. With 70% average humidity and 31 inches of annual rainfall, most Flint houses (median age 1955) are vulnerable to moisture problems. A contractor this highly rated has likely handled the specific challenges your home faces, whether it's basement seepage, attic moisture, or wall cavity growth. Typical remediation projects in this area run $1,200 to $3,950, so you're getting a sense of what to budget before you call.

Michigan doesn't require a specific mold remediation license, so do your homework before hiring. Ask Bio Star Services if their technicians hold IICRC S520 certification, and verify they carry both general liability and pollution liability insurance - this protects you if something goes wrong during the job. One important note: get a written estimate and scope of work upfront, since mold projects can reveal hidden damage once walls or crawl spaces are opened.
