What our Customers have to say

Kara Doberstein

" What a wonderful experience. I needed to have the front locks and door knobs on my front door replaced. Within 24 hours of calling, Paul came over and surpassed my expectations. He made sure he had all the correct hardware that would match the preexisting pieces we would leave in place. He went the extra mile to make sure that the hardware was not only functional, but he also cleaned up our old deadbolt that had years of old paint on it. He was cheerful, courteous, and meticulous. Thank you Paul! I will strongly recommend your services to my friends and family.."

There's little difference in the actual equipment from one security system to the next. What truly distinguishes a security system is how it's designed... how it's implemented... and how it's serviced.
