"Andrew Brown from Alarm Protection Group facilitated the installation of our home security system. He was a very helpful and informative, and was not pushy, as with other ADT sales reps. He followed up with us after the system was installed to see if we had any questions or concerns re the system. I highly recommend Andrew to anyone who is interested in a home security system."

"I have used L&R security for several residential properties over the last 15 years or so and I’ve never been disappointed! I recently bought a restaurant and had L&R install a full state of the art security system with 8 HD cameras and it has been a blessing in so many ways! Ray and his team have always been there for system support when we had questions or needed support and the quality of their work has always been on point. Charity starts at home so I’m more than happy to give local family owned companies my business, especially during these trying times."

"ADT has exceeded my expectations! The system is reliable, the app is easy to use, and the customer service team is always helpful. I appreciate the environmental monitoring features, which go beyond just security. Knowing my home is protected 24/7 is priceless. I highly recommend ADT to anyone looking for a trustworthy security provider."

"I had used this company before for a kitchen counter installation. I was satisfied with the work and price. This time even though the technician know I wanted an electrical outlet put in, he came without any of the necessary parts. So, I paid for him to go to Home Depot to get the materials. This took an hour. I could have gone and gotten the materials myself had I known he wouldn't have what he needed. When you make the appointment, you are told you will have to pay for the time it takes the technician to get what he needs. But, I just assumed since he knew what I wanted done, that he would come with the parts."
