"Great guys! Sentry was professional, punctual and did the job well. It was a lot more tedious and detailed then expected, but they did what they had to do to get us what we asked for. Very pleased."

"Showed up on time. Rehabilitated a 15 year old system instead of selling me a new one. Billed me for the minimum of time even though they could have billed for three times as much. Were honest and professional. Absolutely use this company."
