About Us

Gilbert Williams Industries Ltd. was formed in December 2012 with the collaboration of Sentinel Sheet Metal and Gas Fitting and Williams Plumbing and Gas Fitting for large commercial and industrial project that required full mechanical services, while residential projects were the divided between the original parent companies.

Effective January, 2016, Gilbert Williams Industries Ltd. completed the merger of Sentinel Sheet Metal and Gas Fitting and Williams Plumbing and Gas Fitting by bringing the residential aspect under GWI’s scope of work and retiring the parent companies. We now offer the same quality work you have enjoyed for years but with a fresh look and streamlined operations to serve you, our customer, even better.
