Sentry stands out I've tried a few security companies, and Sentry stands out positively. Staffing is a challenge I think for all of us, and Security is certainly feeling this. We've had hiccups related to staffing, but Sentry always responded quickly and proactively to make sure we were covered.

Reliable and Responsive Reliable and responsive for security needs on construction project in San Francisco. Quick and easy to get started and easy to maintain.

Great Quality Guards and Excellent Service My jobsite in Concord was a victim of arson and we hired Sentry Security Services for the repairs and rebuild and we could not be happier. I have already recommended Sentry to numerous co-workers and former co-workers now at other GC's. After the fire, everyone from Ownership and our side (the GC) was naturally very stressed and worried about having another incident so we asked a lot of last minute changes to the guard details (adding guards, changing routes, adding cameras and lights etc.) and Sentry really stepped up and made it all happen. Even when there was not an available guard for night patrol, they would send a supervisor. Just recently, one of their guards stopped an arson suspect messing with our fence with a gas can and a lighter in his hand. They provide very thorough reports and really have made this rebuild easier/less stressful knowing they are patrolling the site. The main day Guard Michelle has been amazing, going above and beyond her duties to make sure everything is running smoothly. All in all I can easily say that Sentry has been the best Security Company I have worked with on a construction site and have played a huge role in finishing the project. We are almost complete with drywall a little over 1 year from the fire and due to Sentry Security, have had a safe and secure site with no further incidents (or successful incidents).

Brian does a great job Security guard Brian does an excellent job. He shows up on time, is friendly, and you can tell he cares about what he does. When he works the morning shift he is always at the gate or runs in to me on site within the first few minutes I am there. We have not been as impressed with some of the other guards. I usually arrive on site around 5am and have caught them sleeping in their cars or nowhere to be found at this time. Our contract covers until 5:30am

Great security company Great security company. Preforming exactly what was asked of them.
