Sentry Security is easy to work with and provides good service.

We were having some issues with our security system and Sentry sent a technician out to detect the problem and resolve the issue. We were pleased with their attention to the problem and concern to make sure we have the safety and protection we were paying for. They were polite, friendly and efficient making it a positive experience.

Office or inside personnel were very engaged. The outside technician was also engaged. However, it has been difficult getting them to establish and complete the follow up work. Just an area of opportunity, I would still recommend them to friends and family.

The in house service was very good, but my experience with questions regarding additional services never went to anywhere.
