United California Glass & Door started as a glass shop in 1991 with a handful of employees and a couple of service trucks. As our customer base increased and the scope of our customer's requests for services expanded, we grew to include swing door, roll-up doors and access control. Eventually, this evolution lead us into CCTV, Revenue Control and Energy Management. Due to the dependence of CCTV and Revenue Control upon computers, it became a natural progression to offer IT services.
