SERVPRO of Lexington, Waltham, Watertown, Arlington, Somerville, Charlestown

SERVPRO of Lexington, Waltham, Watertown, Arlington, Somerville, Charlestown holds a 5-star rating across 499 Google reviews, which is noteworthy given Somerville's climate challenges. With 71% average relative humidity and 50 inches of annual rainfall, combined with a median home age of 1938, mold risk here is real. When a contractor has that level of local reputation in a moisture-prone area with older housing stock, it's worth considering - especially if you're weighing whether to call them in the first place.

Before hiring, know that this firm is listed as a mold inspector. Industry standards flag a potential conflict of interest when the same company both inspects for mold and performs remediation work. Massachusetts doesn't require a specific mold remediation license, but look for contractors holding IICRC S520 certification and verify they're registered with the Massachusetts Office of Consumer Affairs. A standalone mold inspection typically costs $200-$600 in this region, so get that quote in writing and consider whether a separate, unaffiliated inspector might give you more neutral findings before committing to remediation.
