We are available for commercial new construction projects throughout the greater Piedmont Triad area. Contact us for a bid on your next project.

We are big enough to handle any size job, yet small enough to offer caring service. We complete jobs on time and on budget and have earned an excellent reputation for our commercial plumbing installation and service throughout the Piedmont Triad area.

Among our qualified and experienced professionals, we have Certified Backflow Preventer Installers and Testers as well as licensed and credentialed medical gas installers (ASSE 6010 Medical Gas Installers Credential in compliance with ASSE 6010 and NFPA99 for installers and accepted nationwide).

We are committed to being first in new technologies. We are the only North Carolina certified installer for Aquatherm polypropylene piping system engineered and priced for chilled water, hydronic heating, and industrial applications.

We offer prefabricated plumbing. Prefabricated plumbing cuts the time of installations practically in half because all of the hard work is already complete. Contact us to learn how this new technology can help you save money on your next project.

We are an exceptionally qualified and experienced contracting company, with a hands-on principled, highly motivated and dedicated staff all anxious to do your projects with highest quality installation, safely and within your time frame. Our success in plumbing has been based on our commitment to performance, integrity and fairness in dealing with our clients.

We have strong, positive relationships with our vendors. These vendors are crucial to competitive pricing and timely delivery of materials — essential to keep projects under budget and delivered ahead of schedule.

Pendergrass & Holder Plumbing has an excellent in-house safety program for both general liability and workman’s compensation.
