In-House Pipe Fabrication

In-house fabrication gives us more efficient use of our employees’ craft skills and speeds up the on-site installation process. Not only does it offer lower labor costs and gives on-hand access to experienced welders and pipe fitters, but having in-house fabrication allows for a more controlled environment to produce high-quality materials.

By centralizing fabrication operations for numerous decentralized projects, economies are gained for all clients through reduced man-hours, greater quality control and mechanical projects completed on time, every time.

Each plumbing/piping assembly is fabricated according to the specification requirements and then shipped to the jobsite for installation by our construction team. By fabricating all of our piping materials in-house rather than on the jobsite, we can ensure higher quality control while saving money.

Testimonials

Bunny Oakes | President, TIS Insurance Services, Inc.

I have had the pleasure to work with Interstate Mechanical Contractors for close to 30 years and can assure you they are the Best of the Best. I believe there are 3 priorities for a successful contractor: Safety, Quality of work and Production. Their commitment to safety and their employees is unquestioned. They do great quality of work and stand behind their work and finally they get the job done. It is an extreme pleasure to work with a company as Professional as IMC.

We have had the pleasure and privilege of handling the performance bonding requirements of Interstate for over 25 years and through two generations of ownership. During that time Interstate has performed admirably and completed work treating all parties with fairness and respect and rendering the owner a quality product. As a grantor of credit in the form of bonding we can ask for no more.
