We have had Alert Protective Services since moving into the house, almost eight years ago. Service has been good throughout that period. Recently we were having an intermittant problem which involved two service calls to resolve. This was as good of a customer service experience as I have ever had. The technicians, Mike and Brian, were knowledgeable and very courteous, arrived promptly and resolved things in a highly satisfactory way. This is a good company with good service and I highly recommend them!
