Professional Construction Security Guards in Los Angeles
Construction sites are theft magnets. With over $1 billion in construction materials stolen annually in California, protecting your project isn't optional—it's essential.
Scaife Protection Services has secured construction sites across Los Angeles County since 1997. Our armed and unarmed construction security guards understand the unique challenges of active job sites. Unlike passive surveillance systems that only record crimes, our guards prevent them through visible presence, active monitoring, and immediate response.
Why Construction Sites Need Security Guards
Construction theft isn't random—it's predictable:
When it happens: Nights and weekends—when legitimate workers are gone and the site is dark. Friday afternoon to Monday morning is a 60+ hour vulnerability window.
What gets taken: Copper wire (always), power tools, building materials, heavy equipment. Anything portable and sellable.
Who does it: Sometimes opportunistic theft. Often organized crews who know exactly what they're looking for and how to move it quickly.
The real cost: Beyond replacement value—project delays, insurance deductibles, crew productivity lost to dealing with the aftermath. The average construction theft costs $10,000-$50,000. Some cost far more.
Beyond theft, you face risks from:
- Equipment theft – Excavators, generators, and tools worth thousands disappear overnight
- Material theft – Copper, lumber, and steel are frequently targeted
- Vandalism and arson – Costing projects weeks in delays and cleanup
- Trespassing liability – Unauthorized visitors create safety and legal risks
- Worker safety concerns – After-hours intrusions endanger early-arriving crews

Coverage Options for Your Project
Construction security isn't one-size-fits-all. We structure coverage based on your project:
Overnight Only
Guards on site from end of work day until morning crew arrives. Most theft happens overnight—this covers your highest-risk window. Most cost-effective option.
Overnight + Weekends
Extended coverage for the long gaps when no one's working. Covers the full vulnerability window from Friday afternoon to Monday morning.
Mobile Patrol
For multi-site contractors: guards patrol between several sites on a scheduled basis. Cost-effective coverage for developers managing multiple projects.

Verified Client Review
"I needed armed security same day for my company's construction project. Scaife came through with a reasonable quote, copies of all insurance and requested documents for the accounting department to quickly set up the company in our system.
Omar was timely on replies and walked me through the process and had someone on-site the same day. I could not have asked for better service.
The team that showed up through the engagement was professional and courteous to all employees. Highly recommended!"

How quickly can you deploy construction security guards?
We offer same-day deployment for urgent needs. For scheduled starts, we typically deploy guards within 24-48 hours after contract signing. Call us at (323) 786-8140 for immediate availability.
Do you provide armed or unarmed construction security guards?
Both. We'll assess your site's risk level, equipment value, and location to recommend the appropriate security level. High-value projects with expensive equipment typically benefit from armed guards as a stronger deterrent. Read our armed vs. unarmed guide →
What are construction security guards trained to do?
Our guards receive construction-specific training covering access control, equipment inventory procedures, incident documentation, emergency response protocols, and coordination with law enforcement. All guards complete California BSIS-mandated training plus our internal construction security program. Learn about our licensing and training →
How much do construction security guards cost?
Costs vary based on armed vs. unarmed guards, shift coverage (overnight, weekend, or 24-hour), and project duration. Most clients find our services cost-effective compared to the risk of a single theft or vandalism incident. See our pricing guide or request a free quote for accurate pricing.
Can one guard cover multiple construction sites?
Yes, through our mobile patrol service. Guards conduct scheduled visits to multiple sites throughout their shift, with GPS-verified check-ins. This provides cost-effective security for developers managing several projects simultaneously.
What happens if there's an incident on-site?
Our guards immediately respond, secure the area, contact law enforcement if needed, document the incident with photos and detailed reports, and notify your emergency contact. You receive a complete incident report within hours.
Do you work with general contractors and subs?
Yes, both. We work directly with GCs on large projects and with specialty contractors who need security for their phase of work.
