What Our Customers Are Saying
"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.”

“On multiple occasions, Guardian Security has come to the rescue on failed security systems caused by other alarm monitoring companies. I appreciate Guardian Security’s ability to follow up on annual inspections, provide information on new programs/technology and suggestions on ways to reduce expenses at my rental properties.”

"Guardians service is exceptional. Their scheduling has vastly improved. They let you know when they will arrive. The same technicians do the work and this expedites the process because they are familiar with the equipment and property. Guardian is a one stop process company for the fire, safety and backflow testing. Their pricing is reasonable also compared to the competition. I fully recommend this company. "
208 Boyslton Building, Seattle WA
"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!"

Seattle Children's Research
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.

I can personally say that it is always a pleasure to have any of the Guardian team members on site for any service matters.
