"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."

"Technicians examined my garage door and diagnosed the problems with it. They completed repairs the same evening and I had a brand new motor assembly which is quiet and working perfectly since. They do nice work."

"Front Door locks broken on my home. Had to take off work, no way to secure my home. Home Advisor put me touch with Colonial Lock Service, Inc. the gentleman on the phone tried to help trouble shoot the problem when that failed a locksmith was dispatched. The locksmith called and said I will be there in an hour. This young man showed up on time and said don't worry I hear to make it better. He had such great friendly personality and did a great job. He replaced both of my locks and said "Sir your new locks turn like butter now". Well that made my laugh but he was so right, my locks never worked so good. It appears when the door was replace 15 years ago the locks never really lined up right. The replacement locks were are not your local hardware style, much better quality. I was quoted a price which having never used a locksmith before I thought was high, however the quick response, great service, better then average hardware and most of all the locksmith had a great friendly attitude. The price was right. This young man shook my hand and thanked me. Right when I thought there was no more good customer service in this world, WOW!"
