"It has been years since we had a home security vendor and professional monitoring. Finally got around to re-adding security to our list of home services. It was more than time. Tried a package from amazon but had issues from the start. Ended up returning it. ADT ended up saving the day. We didn’t want to waste any more time with cheap security products. ADT had been the perfect fit for what we were looking for and needing."

"I have them installed security cameras in my house. The workers were professional and knowledgeable. The equipments of their choice are also good. I paid more than I originally expected, but overall speaking the experience is good and I am comfortable."

"I just had him come out to hang up a couple vinyl shutters on my second story. There were some issues with the shutters (not his fault), and he was able to work around that and get them hung securely."

"I am so delighted with the work that Jose and Jesse did in my home today. Jose was very prompt with phone calls and scheduling the visit. They are very respectful, understand how to fix things properly (they fixed things that others have worked on), clean up after themselves, and are just such wonderful gentlemen. I have plenty more for them to do! You will be very pleased with the quality of services and respect received."
