About William C. Diamond Plumbing and Heating

Diamond-Quality Plumbing & Heating Services in Livingston

William C. DiamondIn 1994, I established my own plumbing company to provide better customer service to the North Jersey community. William C Diamond Plumbing and Heating, Inc has developed into one of the most reliable plumbing and heating contractors serving Livingston, NJ and surrounding areas.

Plumbing expertise runs in the family. My grandfather was a plumber, and I followed in his footsteps by getting involved in the industry as a teenager. Over the years I have worked my way up to master plumber and continue to provide on-site support to ensure that our customers receive the quality results they deserve.
