Overview
Construction sites are prime targets for theft, vandalism, and unauthorized access — and every incident costs you money and delays your project. Our construction site security officers provide after-hours protection that stops criminals before they can act. We secure your heavy equipment, tools, copper wiring, lumber, and other high-value materials. Our officers conduct thorough perimeter checks, verify that all gates and containers are locked, and maintain detailed logs so you know your site is protected every night.

Construction Site Security at a closer look
What construction site security covers
Construction sites are most vulnerable when the crew has gone home. Officers provide after-hours, weekend, and holiday coverage, patrolling fencing and gates, checking that containers and equipment are secured, and watching for unauthorized entry. They log each round and escalate anything unusual, so the site is accounted for even when no one else is there.
Protecting materials and heavy equipment
Copper wiring, tools, fuel, lumber, and machinery are all attractive targets. Officers verify that storage containers, trailers, and equipment are locked and undisturbed, watch for signs of forced entry, and document conditions with reports and photos. That record gives you a clear nightly picture and useful evidence if something does go missing.
Working around an active site
Construction sites change daily, so officers stay in step with the project. They coordinate with the general contractor and site superintendent on access rules, deliveries, and safety requirements, and they respect the schedule of trades working late. When hot work or a system impairment triggers a fire watch, that coverage can be folded into the same assignment.
Mobile patrol and multi-site options
Not every site needs a dedicated overnight post. Mobile patrol can check several nearby sites on a randomized route, which suits projects with lower on-site risk or multiple locations under one contractor. If risk increases, we can move to a fixed overnight officer without changing providers.
Service areas
We provide construction site security throughout California, including San Francisco, Los Angeles, Lathrop, Sacramento, San Jose.
