Great company. They installed an alarm system along with some cameras in my home and also my business. Very professional and courteous. I would highly recommend them.

Very Professional Company

I called Suffolk Lock & Security because my home was burglarized. They responded to my initial phone call within an hour and repaired my door lock and door frame, which was kicked in by the thief. Upon their arrival, the technician also informed me that they installed home security systems. The technician provided me with a home alarm estimate on the spot and installed it the same day!!!!! Unbelievable service!!!!!! A+++++ Company!

my business had the need for an access sexurity system. After meeting with many companies It was apparent Suffolk Lock & Security Pros were the best of the best. They spent a great deal of time educating both myself and the head of my security dept. The end result was a quality job at a fair price. Keep up the good work
