Master Sheet Metal License
Massachusetts-issued master license authorizing licensed sheet-metal and ductwork fabrication and installation for commercial buildings in the Commonwealth.
Certified Welding
Certified welds tested to code standards and documentable for inspection and project records. Required for structural connections, pressure systems, and any work that needs a formal paper trail.
Licensed & Insured in MA
Fully licensed mechanical contractor in Massachusetts, carrying liability insurance. Documentation available on request — so your GC, owner, or inspector can verify before work starts.
What this means for you
Credentials protect your project.
An unlicensed or uncertified mechanical contractor creates liability — for your project, your GC, and the building owner. When the inspector shows up or the lender runs a final check, the wrong answer on licensing or insurance can stop a job cold.
Norkum's credentials mean the work is legal, inspectable, and documentable. Our certified welds can be submitted for record. Our sheet metal license backs every duct we hang. Our OSHA 30 status keeps the jobsite controlled and our crew safe.
If you need proof of any credential before work starts, contact us. We'll provide the documentation the same day.
