"Our dealings with Protect Your Home/ADT were delightful. We received a call back very fast after requesting a quote through Angie's List. We were able to complete everything on the phone; there was no paperwork or downtime. I had to call Customer Service with a question about the keypad, and they ended up telling me other helpful details on top of my original question."

"I had a bit of trouble with my molding around the doors vs how the system was designed. The tech guy hung with me for 39 minutes until it was perfect. I called customer service a couple times after that with questions that came up. The customer service team are professional and knowledgeable."

"I had a security system in place that had transferred ownership to 3 companies in total. I needed service on the system and received poor customer service and outrageous pricing for a small service needed. That inspired me to look elsewhere for a new security system provider. I came across Jeremy and Larry from 1st Security LLC and all I can say, being a person in the service industry, they came through big time. Not only were they punctual and knowledgeable, they were plain old nice !!!! From the quote with Jeremy to the install with Larry, it was a pleasurable experience and one that I would recommend over and over again."

"I communicated with Rob Calbo for services of a background check with CSI Secure Solutions and he was fantastic.
He spoke with me in a very professional manner and put me at ease right away.
The process was seamless and my request was delivered very efficiently. Within just a few hours of providing them with information, I was able to get feedback. Rob took the time to speak with me and answered all of my questions.
I will definitely be using them again in the future should the need arise, and I would definitely recommend them as being very efficient, professional and reliable.
