Contra Costa County Security Guard Services
Premier Nationwide Security provides licensed commercial security guard services, armed and unarmed, across Contra Costa County, from Richmond and Martinez industrial sites to Walnut Creek and San Ramon corporate campuses. Every officer works from a site-specific post order, backed by GPS-verified patrols and a local field supervisor, not a call center reading from a script.

A Guard on a Post Is Not a Security Program
A Richmond industrial site and a Walnut Creek office campus do not run on the same schedule or face the same risks. Real coverage depends on a post order written for your specific site, not a template.

“A previous vendor did not show up for a night shift. Premier Nationwide had someone on-site the same day, and I have not had to think about coverage since.”

5-Star Reviews on Google From Real Contra Costa County Clients
What Clients Actually Say
I had a great experience working with this company. I found them to be incredibly professional, reliable, and responsive. I would use them again in a heartbeat.
Within 30 minutes they had a guard on site when our previous vendor failed to show up. They are reliable, professional and accountable.
Premier Nationwide Security Guard Services is by far one of the best companies I have done business with. Every guard they have is always dressed appropriately, has a great personality, and a positive attitude.
Common Questions From Contra Costa County Property Managers
Do you provide 24-hour security guards near me in Contra Costa County?
Yes. We are a private security company with round-the-clock coverage across Contra Costa County, so you can reach a real person any hour, not a call center.
My last guard company sent someone new every week who didn’t know our property. How is this different?
Officers are assigned to your property rather than to open shifts, with site-specific orientation before their first day. They already know your access points and expectations instead of learning on the job.
Can you provide on-site security for an industrial or refinery-adjacent facility?
Yes. We provide perimeter patrol, contractor and vendor access control, and coordinated coverage built around industrial safety protocols.
Do you provide corporate campus security in Walnut Creek or San Ramon?
Yes. We provide access control and visitor management for corporate campuses throughout the Walnut Creek and San Ramon Valley areas.
Do you provide both armed and unarmed security officers?
Yes. The right coverage depends on the property, its risk level, public interaction, and access conditions. We will walk through it with you and recommend what actually fits.
How do I know my guards are actually doing their patrols?
GPS attendance verification, patrol documentation, and daily activity reports give you a real record, rather than relying on a guard’s word for it.
Do you provide construction site security and fire watch in Contra Costa County?
Yes. We support controlled access, equipment protection, perimeter awareness, and after-hours coverage for construction sites, along with fire watch for alarm outages, sprinkler impairments, and other qualifying conditions.

Contra Costa County, including Concord, Walnut Creek, Martinez, Pleasant Hill, Lafayette, San Ramon, Danville, Richmond, Antioch, Pittsburg, and Brentwood.
Is Premier Nationwide Security licensed and insured?
Yes. We are licensed under California BSIS as a Private Patrol Operator, PPO #15857, and fully insured. You can verify this directly with the state.

I need coverage soon. How fast can you actually start?
It depends on location, schedule, and staffing availability. We will give you a real timeline, not a runaround. For anything urgent, call 888-251-6607 directly.
