Fabrication

We operate a full production shop for the fabrication of piping systems for plumbing and HVAC. The controlled environment allows us for better quality and we can produce more in a shorter period of time. Our fab shop has helped our customers with both completion time and money spent on projects.

“We can depend on Harold Brothers Mechanical from start to finish. They are always a team player and have earned the reputation as a premier subcontractor from performance, safety and quality with Callahan Construction.”
