SERVPRO of Portland, South Portland and The Sebago Lake Region

SERVPRO of Portland, South Portland and The Sebago Lake Region holds a 4.7-star rating across 112 Google reviews, which is noteworthy given the climate challenges homeowners face here. Portland's 72% average relative humidity and 47 inches of annual rainfall create ideal conditions for mold growth, especially in homes with a median age of 1950. A strong rating in this environment suggests the company has handled the moisture-related problems that older homes in the region commonly experience.

Before hiring, understand that this company is listed as a mold inspector - a role that creates a potential conflict of interest when the same firm also performs remediation work. Maine doesn't require a specific mold remediation license, so verify that any contractor you hire holds a relevant state contractor license and carries appropriate insurance. Ask whether they hold IICRC S520 certification, the industry standard for mold remediation professionals. A standalone mold inspection in this area typically costs $200-$600, so get that quoted separately and consider whether you want an independent inspector to evaluate the scope of any remediation work before proceeding.
