Different Name.
Same Great Service!

Mansfield Alarm Is Now Part of the Guardian Security Family!

Dear Mansfield Alarm customer,

After serving Yakima and the surrounding area for over 60 years, Mansfield Alarm is excited to announce that we have become part of the Guardian Security family.

My father started this business back in 1958 and we are very proud of the way we have served our customers and the community over the years. In many ways, Mansfield and Guardian are almost mirror images of each other. Guardian started over 40 years ago and has been owned by the same family for over four decades. Guardian has been in Yakima for over 12 years, and has additional offices in Seattle, Tacoma and Bellingham. Guardian has demonstrated over the years our same commitment to servicing customers and the community. We will now operate as Mansfield Alarm Co., A Division of Guardian Security and are the most experienced family owned provider of life and property services in Washington State.

By combining with Guardian, Mansfield now has more technicians and a much wider selection of products that we can offer to help solve all of your monitoring, security, and fire alarm needs. I truly believe the "new" Mansfield Alarm is in a better position to serve our customers going forward.

Our contact information remains unchanged.

In closing, we again want to thank you for your support over the years and look forward to continuing to have you as a customer in the future.
