Construction site security stops the copper theft, equipment loss, and after-hours trespassing that stall Southern California builds. Our licensed officers hold the gate, log every contractor, and patrol active and idle sites from Downtown LA to the Inland Empire.
Tools, copper wire, and heavy equipment make a job site the easiest target on the block once crews leave for the day. Officers control who comes through the gate, log deliveries and subcontractors, and walk the perimeter through the night so your build stays on schedule and on budget. Our officers are state-licensed through the California Bureau of Security and Investigative Services (BSIS).
