Professional Construction Site Security Guards Services You Can Trust 24/7
The right construction site security guards are the difference between a property that gets tested and one that gets skipped. National Protective Service deploys licensed, vetted officers trained to stop the after-hours theft of tools, copper, fuel, and equipment that costs builders real money. Most jobsite theft happens overnight and on weekends — our coverage is built around exactly those hours, with access control during working hours and patrols after.

The guard at your gate sets the tone for the whole site: contractors sign in, deliveries get verified, and after dark, the property is walked — not watched from a truck. We staff builders’ sites with officers who understand jobsite rhythm, from first pour to punch list.

Officers Trained for the Job
Every officer completes background checks, state licensing, de-escalation training, and site-specific post orders before the first shift. Supervisors inspect posts on rotation, and every shift closes with a documented report — so you always know who was there, when, and what they saw.
Phase-Aware Site Protection
A jobsite’s exposure changes as it rises: open excavation, framed lumber, copper-filled walls, finished fixtures. Coverage should change with it. We plan security by phase — heavier presence when materials peak, patrol-only when the site hardens — and adjust as your schedule moves. Gate control, contractor sign-in, delivery verification, and after-hours patrols run under one plan and one point of contact.
Also Available: job site security guards
If your risk picture includes more than one exposure, job site security guards can run under the same agreement — one supervisor, one reporting format, one invoice. We will scope both in the same assessment visit.
What Drives the Cost
Four things set your rate: the coverage type, the hours you actually need, the site’s risk profile, and the contract term. We scope all four in a free assessment, then quote a firm number — no estimates that drift, no charges that appear later. If patrols or a hybrid plan can protect your property for less than a standing post, that is what we will recommend.
Licensed, Trained, and Accountable
Every post is staffed by California BSIS-licensed officers (PPO 120545), and our officers work to site-safety practices consistent with OSHA workplace guidelines; our team follows professional standards aligned with ASIS International, the leading association for security management professionals. The same documented standard covers tool theft prevention jobsite — training, verification, and paperwork you can check, not just claims on a website.
