Service & Support

Our customers ask for Sentry Security technicians by name


We focus on doing the job right, being fair and developing a strong end user relationship with our customers

On average, Sentry’s customer base has been with Sentry for more than 12 years.  We have a 93.1% annualized customer retention rate- due in large part to Sentry being independent, competent, accessible and local.  We appreciate that the vast majority of customers positively refer Sentry to their colleagues and friends.

We Believe in Stability & Longevity

We are proud to have built a team of professionals to serve our customers.  Sentry customers appreciate the expertise and continuity of our veteran Field Technicians.  Our Office Staff have substantial industry experience and most have long tenures with Sentry and its legacy companies acquired through mergers.
