Having had security cameras with an alarm system fitted to our outside premises by other engineers, it had always given problems and with little to no aftercare from previous engineers, we are delighted to have found Zest. The Zest engineer Declan who came out to us completely revamped the complicated old system. Declan was very knowledgeable, nothing was too much trouble and he has left us with a perfectly working system and also the reassurance of good aftercare, it is only a matter of contacting Zest if we need something tweaked or repaired in future. They are a great company to deal with and they really know their stuff when it comes to security systems. We only wish we had come across their business initially and they had installed our system from scratch! – Seamus Black Haulage
