How to choose a mold remediation company in Ortonville
Mold needs water. If the leak or the humidity problem stays, the mold comes back. The U.S. EPA says the first step is to fix the water problem.
The EPA says an area larger than about 10 square feet calls for its remediation guide, and a large area is a job for a trained professional.
Good remediation work isolates the area with plastic containment and air filtration, removes what cannot be cleaned, such as wet drywall and insulation, and cleans and dries what stays.
Michigan has no state licence for mold remediation. Training such as the IICRC Applied Microbial Remediation Technician course shows the crew learned the standard (S520). Rebuild work needs a LARA builder or maintenance and alteration licence.
Ask how the company will show the job is done, and get the moisture readings and photos in writing. Many homeowners insurance policies limit mold coverage, so read your policy before work starts.
