Before you hire anyone for mold remediation in Newton, check that they're registered with Massachusetts' Office of Consumer Affairs - it's required for home improvement contractors. You'll also want to verify they hold IICRC S520 certification, since Massachusetts doesn't issue a specific mold remediation license. Given that Newton's climate brings 71% relative humidity and frequent rain, mold can be a real concern, especially in older homes like many of the ones built around 1941 that still stand in the area today.
