Pipefitter licensing in Delaware

There is no Delaware fitter card — and on the mechanical side, no worker license at all: the HVACR ladder is MASTER-ONLY, and supervised workers are statutorily EXEMPT. Your traveler paperwork on hydronic and comfort piping is zero; verify the employer's master-anchored license instead. The one scope that changes the answer is PLUMBING — Delaware licenses journeyman and master plumbers, and Maryland masters have a level-scoped lane into that world.

Nothing pending for you on the mechanical side — supervised workers are exempt by statute, so there is no license to wait on.

Master-level only: the master HVACR classes anchor the licensed operation (education and experience routes through the Division of Professional Regulation). Plumbing-scoped work uses that board's journeyman and master exams.

No apprentice credential on the mechanical side — green hands work exempt under the master-anchored operation. Plumbing apprenticeship rides the plumber ladder.

None — the state board regime is statewide.

Verify the employer: the master-HVACR-anchored license for hydronic and comfort piping scope, or the master plumber anchor for plumbing scope, plus Delaware business licensure — all at DELPROS. The worker-side question is always 'is the work plumbing-scoped?'
