Aspen Environmental, LLC has a 4.8-star rating across 115 Google reviews. If you're dealing with mold in Boston, you're dealing with a real problem - the city's 73% average humidity and 44 inches of annual rain create ideal conditions for mold growth. Older homes like Boston's median house (built in 1943) are especially vulnerable because moisture finds its way into aging walls and foundations. When you're ready to call someone in, make sure they're registered with Massachusetts' Office of Consumer Affairs, since the state doesn't have a specific mold license but does require this registration for home improvement contractors.
Before you hire anyone for a typical remediation project, which might run $2,000 to $6,000 in this area, ask whether they hold IICRC S520 certification - that's the credential that actually means something in mold work. Get a few quotes and don't rush the decision. Once you've narrowed it down, verify their registration status and ask for references from other Boston homeowners before signing any contract.
