Serving Washington State For Over 40 Years.
From our Seattle-based Central Station, we serve one of the largest customer bases of locally monitored accounts, coordinating dispatch of police, fire, and medical emergency services for our customers.
No other security company can match Guardian's range of experience in integrated system design. And because we also install and service the systems we design, we understand the value of intelligent and farsighted planning.
Our company employs over 170 residents in Washington State. We are committed to supporting our region. Locally owned and operated, we’re big enough to do the job, but small enough to care about the details of your system.

"Sean Humphrey House has used Guardian's Security's services for several years. We have been consistently impressed with their services, prompt scheduling of appointments/inspections, thoroughness and accuracy of work performed by technicians/specialists, and professionalism of office/support staff. Guardian Security completes our annual inspections, and repair needs, in a timely manner and for reasonable costs/fees. We highly recommend them!"
"Guardian Security set up the appointment to test our sprinkler systems, fire alarm systems, and everything else! They were very exact and prompt. The men arrived on time, were conscious of our request to test the alarms later so that our residents would not be frightened. They worked the better part of the day, not even stopping for lunch. They were polite and very professional. I was very impressed."
“I have found the services provided by Guardian to be both flexible and responsive to the needs of my clients. They have always been quick to respond and excellent at troubleshooting problems with systems suffering from construction defects and poor installation.”

"Our company underwent a state survey, and as a result we were required to have additional testing on our smoke alarms and zoned fire alarm system. The survey requirements needed to be met per state code as well as on a specific, quick, timeline. Guardian Security was extremely responsive. I made contact with Guardian, and was moved quickly and efficiently to the appropriate persons. Testing was completed in our office setting, during business hours, without hassle or disruption to our business. Everyone from reception, to scheduling, and the service technicians who performed the testing were exceptionally helpful. Very professional service, top to bottom!"

"The prompt service call was completed by a knowledgeable and courteous service technician who found the problem quickly and restored our service in a timely manner. She acted in a professional manner and treated us with respect and consideration. I'd be happy to have this technician at our facility in the future, and feel that she portrays the highest standards for your company. Bravo!"

"There are many fire safety companies in the Seattle/King County area. Some who charge a bit less than Guardian Security. For the last thirty years, I have chosen Guardian Security to service and repair our buildings because of their knowledge and quality. Their advance notice of upcoming renewals takes scheduling off my busy "To Do" list and gives me plenty of time to alert the residents of the upcoming service. Their capability of quickly attending to an emergency is most comforting. I cannot imagine managing this aspect of our buildings without Guardian Security."

"Guardian security is more than our contracted alarm systems company and technicians. Every person I interact with at Guardian treats me with the utmost respect, professionalism and knowledge. I can personally say that it is always a pleasure to have any of the Guardian team members on site for any service matters."

"Two technicians came to my building to identify a solution for repairing a non-working alarm. They quickly diagnosed the issue as the alarm being disconnected sometime in the past. They re-connected the wires and solved the issue saving our company thousands of dollars in equipment rental."
"The Mountaineers Baker Lodge replies on GUARDIAN SECURITY to ensure the safety of our guests. Their fire alarm inspection and fire extinguisher services are excellent. Knowing that the alarm system is tested and fully functional give the Baker Lodge hosts peace of mind. Thanks Guardian!!"
