Insulation licensing in Maryland.
Maryland has no state competency license for commercial insulation contractors. The Maryland Home Improvement Commission license covers improvements to residences and adjacent land only, so it is a residential consumer protection credential rather than a commercial trade qualification. The credential that genuinely matters for insulation is the MDE asbestos license: companies that remove, repair or contain asbestos must hold an annually renewed state license, which requires approved training and passing the Maryland third-party examination, and must notify MDE at least ten working days before removal work. Ask for the current MDE asbestos license number and confirm the training and exam records behind it.
Licensing authority: No state commercial contractor license; Maryland Department of the Environment licenses asbestos removal and encapsulation contractors under COMAR 26.11.21. Confirm current rules with the agency.
