Company Overview

Westco Service Company was founded in 1991 on the principle of superior customer service and satisfaction. We began with four employees providing service to the Los Angeles County area and through steady growth, generated by customer satisfaction, repeat clientele and referrals we are now found throughout the Southern California area. We currently employ an average of 80 union workers who are signatory to the Local 105, 250, and 761 unions.

Our company is unique in the fact that we are a full service mechanical company that can develop any size project from design and engineering, through construction and commissioning to preventative maintenance on the installed equipment.

We offer 24 hour emergency service and repairs through our state of the art dispatch center.

We take pride in our ability to handle each customer’s needs from a small repair to a multi-million dollar project. We are hospital and health care specialists and also have extensive experience with computer room installations, data centers and server rooms.
