We went with yale alarm because we had our new composite front door done with them and were so impressed we just had to let them do something else for us. Within 2 hours of placing the order for the alarm the fitter called to confirm a fitting date (now thats what i call service). We chose the following Wednesday as it was convenient for us, although he could have fitted sooner. The night before fitting the fitter contacted us to reconfirm and on the fitting day he arrived on time, with everything he needed. He was very professional and just got on with the job. We had the free survey which was very useful as he went around the whole house and pointed out any weak spots. Once the alarm was fitted he explained how to use the alarm and how to set it etc. We went for the wireless alarm with key fob etc which is brilliant. We now have a house that is safe and secure thanks to yale alarm and yale doors. Hmm I wonder if they do windows? I can not recommend this company enough.
