About Monroe Plumbing & Heating - (800) 295-4277 | Monroe MI - subpageSome of our newer, large industrial clients that are not familiar with Monroe Plumbing & Heating Company look at our name and think, “These guys are just some small, residential plumbing contractors who don’t know anything about our mechanical contracting needs," all because we don’t have a fancy name like Monroe Mechanical Contractors, Inc. or Monroe Industrial Piping, Ltd.

In fact, many of our best friends and customers have urged us to change our name to better reflect our company's history. A history that has included 90% of our work for large industrial and commercial clients like Detroit Edison Company, North Star Steel, and the University of Michigan. In addition, we are just as "at home" with T.I.G. welding, power piping, and stainless steel as we are with PVC and copper piping.

We like our name though. It represents the fact that for over sixty-seven years, Monroe Plumbing & Heating Company has meant quality mechanical contracting and we are second-to-none in Southeast Michigan. We are proud of our name and heritage.

So, if you are impressed with a name, give the job to Big City Precision Process Pipe Power System Mechanical Contracting Company.

If you are impressed with results, the name is: MONROE PLUMBING & HEATING COMPANY.


We are Very Proud to Announce That We Have Been Designated as an MSCA STAR Contractor!
