Massachusetts: verify, don’t scrape
This page does not list sweep names. CSIA’s finder is the homeowner tool for CSIA credentials, and CSIA says that list is not for marketing. There is no statewide occupational license roster of chimney sweeps to transcribe here. Use the outbound links. Do not treat this page as a referral.
Massachusetts does not issue a chimney-sweep occupational license. Contractors, subcontractors, partnerships, or corporations that solicit, bid on, or perform contracting work on an existing, owner-occupied residential property of one to four units must register as a Home Improvement Contractor (HIC). Mass.gov is explicit that an HIC registration is different from a Construction Supervisor License (CSL); they are not interchangeable. Structural work may need the CSL. Confirm both when the job is more than a cleaning.
Before you hire, read When to sweep a chimney.
