Guardian Recovery Services

Guardian Recovery Services holds a 4.8-star rating across 110 Google reviews, which matters significantly for Sterling Heights homeowners. Your older homes (median built 1977) combined with the area's 70% average humidity and 32 inches of annual rainfall create ideal conditions for mold growth. That strong rating suggests Guardian has proven experience tackling the moisture problems common in this climate and in houses your age. Most remediation projects in Sterling Heights run between $1,200 and $3,950, so you'll want a contractor who understands local conditions and delivers results that justify the cost.

Michigan doesn't require a specific mold remediation license, so verification falls on you. Before hiring, confirm that Guardian carries IICRC S520 certification, which signals proper training and standards. You'll also want to verify they carry both general liability and pollution liability insurance, protecting you if something goes wrong during the work. Don't skip this step - it's your main safeguard when licensing requirements are minimal.
