New front door
Quality of the product and choice of styles that suited our property. We could also choose the glass and colour we wanted.I was very disappointed when I realised that the new door was smaller than the original.The new door was 30inches wide, the old door was 33inches wide had this been explained to us before we would have reconsidered.
