"Eli arrived punctually after calling to alert me of his arrival. Once here, after hearing the problem, he looked at the door and realized the problem was that the door had settled low. I didn't need new locks, as I had thought; instead, he simply fixed the door so the locks fit correctly again. Instead of having to pay for new hardware, I was only charged for the visit and 15 minutes of time."

"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."
