Case Study

Paragon Security received a call to install a new lock system for a residential storage facility. The door needed to be accessible to residents and staff, however also needed to be locked at all times for safety purposes. Our locksmith furnished and installed a brand new Mul-T-Lock cylinder and top guard plate, a Segal slam lock, and a Legacy door sweep to ensure the door is sealed for safety.

Trusted Solutions, Exceptional Results

    Roland M. New York, NY
  • Kind, quick and efficient
    “I called and Paul answered and arrived at my apartment very quickly. My bathroom door had accidentally locked and Paul got it open within a minute.”

  • I have nothing but praise for Paragon
    “I have nothing but praise for Paragon. My apartment intercom handset hasn’t worked for a long time. My neighbor’s handset was replaced by Paragon and she recommended I call. Within a couple of days my inoperative equipment was replaced by a wonderful, timely, considerate young man who explained that the system is soon to be obsolete and I was just in time as the current equipment is not being made. I’m hoping my building considers Paragon to install a new system to bring us into the 21st century. Thank you for your excellent service.”

  • Highly recommend!
    “We had an emergency when the handle on our living room French doors broke and the doors wouldn't stay closed. We called Paragon, and Michael came over immediately, quickly diagnosed the problem, and spent several hours carefully adjusting the mechanism so the doors worked properly again. Without his help, it could have been a real disaster. We're incredibly grateful for his prompt, kind, smart, and truly professional work - highly recommend!”
