"SafeStreets’ alarm system is fantastic. The motion sensors, door/window contacts, and cameras work flawlessly. The home automation features are a huge plus—I can control everything from my phone. Highly recommend SafeStreets to anyone looking for reliable security."

"Last weekend had someone pry our side door open to our exterior garage and the ADT door sensor picked it up immediately. The alarm siren was loud and scared the person off. Someone from the response center called within 30 seconds. We’re fortunate that the security system did what it is supposed to. Feels like we made the right call going with an ADT security system."

"Excellent job! Mr Temur K was incredible fast, professional, and made sure my window AC unit was secure and cooling properly perfectly. Highly recommend his installation services! 👍"

"They were pleasant and professional. They arrived quickly, assessed the situation & fixed the problem. I wanted a security lock, so had to pay more."

"Great company! I needed to replace my regular door and security door. Valentino (the owner) had come by for a free assessment and estimate. He provided a fair assessment without being pushy which I greatly appreciated. The doors were custom made according to the specifications I had chosen. The crew that came by to do the installation were friendly, professional and were respectful of my property. As part of the installation of the doors, they also had to do new jambs and the bottom (I previously had a half step). The end result is absolutely beautiful and I am so happy with my new doors. They are well sealed when closed and I no longer have a draft. I highly recommend Custom Windows & Doors!!"
