Michigan licenses mechanical contractors by classification, including Hydronic Heating and Cooling and Process Piping. Boilers and their piping need a state boiler installer license and a boiler permit before work starts.
How we check credentials →Compare welding procedures and welder qualifications, testing and documentation, safety program, schedule and warranty, not just the bottom line.
Pipefitters build and repair the piping that carries steam, hot and chilled water, compressed air, gases, chemicals and process fluids in plants, hospitals, schools and commercial buildings. Use this page to pick the right service, request quotes from Metro Detroit piping contractors, and check the licenses and code documentation that matter. Need structural or custom metal welding instead? See welders. Setting pumps and machinery? Compare millwrights. For domestic water, drains and residential gas lines, see plumbers.
Say what the system carries, its design pressure and temperature, pipe material and joining method (welded, threaded, grooved, brazed), and the governing code or owner specification. Note whether the work is new construction, a tie-in to a live system or a shutdown repair, and share drawings, P&IDs or photos.
LARA licenses mechanical contractors by classification, including Hydronic Heating and Cooling and Process Piping, HVAC Equipment and specialty classifications such as Fuel Gas Piping. Mechanical work needs a permit from the enforcing agency before it starts, except for minor part replacement. Boilers outside of homes, and their piping, fall under the state Boiler Division: work needs a boiler installer license and a boiler permit, and welding procedures qualified to ASME Section IX must be filed before welding. Medical gas systems fall under the Michigan plumbing code.
Ask for welding procedure specifications and welder qualification records, the pressure test and inspection plan, turnover documentation, and the contractor's safety program for hot work and confined spaces. Compare schedules and shutdown plans as closely as price. Then check verification status as described in How We Vet.
Contractors serve plants and facilities in all six counties, but permits come from the enforcing agency for the site, which may be the state, the county or the city. In Detroit, mechanical permits and inspections go through BSEED, and the BSEED Boiler Division handles boiler inspections. Browse by city or county, such as Wayne or Macomb.
