Requirements, license levels, and the issuing authority, sourced from Connecticut's official board.
Connecticut licenses sheet metal work as an individual trade: the Department of Consumer Protection states that sheet metal contractors and journeymen must be licensed by the Department, and defines sheet metal work as the installation, erection, replacement, repairs or alteration of ferrous or non ferrous ductwork systems. Both the contractor and the journeyperson credentials are issued to individuals, not to companies.
| Requirements | Only individuals may apply; the Department does not accept company applications. Journeyperson licences require completion of a registered apprenticeship or equivalent: the SM-2 path is 8,000 hours of on the job training plus 576 hours of classroom instruction, and the SM-4 path is 4,000 hours of on the job training plus 288 hours of classroom instruction. Applicants submit either an original Letter of Apprenticeship Completion from the Connecticut Department of Labor or notarized employer letters detailing the work experience plus proof of the related classroom instruction. Contractor licences (SM-1, SM-3, SM-5) require two years as a licensed journeyperson or the equivalent. Every individual applicant must take an examination, with the exam fee paid directly to the exam vendor. Application fees are $150 for a contractor licence and $90 for a journeyperson licence, both non refundable. Journeypersons must work under a contractor holding the corresponding contractor licence, and the SM-3 and SM-4 scope is limited to buildings with air handling units not exceeding 35 tons of cooling or fans or blowers not exceeding 14,000 cubic feet per minute. |
| Reciprocity | The Department's heating, cooling and sheet metal work licensing page states that Connecticut does not have reciprocal agreements with any other jurisdiction. Applicants who hold an out of state licence may instead apply through the equivalent experience and training path, submitting copies of all occupational trade licences held in any state or jurisdiction, the laws and regulations of that jurisdiction reflecting the requirements met to obtain them, and the scope of work of those licences. |
| Renewal | All heating, cooling and sheet metal work licences expire annually on August 31. Renewal fees are $150 for contractors and $120 for journeypersons. Sheet metal is not listed among the occupations on the Department's Continuing Education for Occupational and Professional Licenses page, which names architects, landscape architects, electricians, home inspectors, registered interior designers, plumbers, swimming pool builders and swimming pool maintainers, so no continuing education requirement is published for sheet metal licensees. |
| Notes | Connecticut licenses sheet metal work as an individual trade: the Department of Consumer Protection states that sheet metal contractors and journeymen must be licensed by the Department, and defines sheet metal work as the installation, erection, replacement, repairs or alteration of ferrous or non ferrous ductwork systems. Both the contractor and the journeyperson credentials are issued to individuals, not to companies. |
