Don't pay that ridiculous price that ADT or the other alarm companies charge you for a simple or even not to simple repair. These guys are fast competent and knowledgeable people who know how to fix it right the first time. ADT charges $150 for the first 15-30 minutes whether it takes 5 minutes or not. then ADT charges around $75.00 every 15 minutes thereafter. If this isn't accurate it's pretty close.
