Full marks to sales for being helpful and informative, no pressure. Loose some marks for delivery - did not arrive when arranged, stayed in all day to assist , no phone call until i contacted them next day, lucky i was able to be at home next day. Loose some marks for installation - at survey to check sizes was advised installer would be in loop regarding delivery and would fit doors within a couple of days. In fact it became 5 days which would have been longer had i not volunteered to assist because a colleague was unable to attend. After install i noticed excessive movement of one of the hinge bearings which was not carrying any weight, installer unable to remedy since no adjustment in hinge. For a few pounds i bought and fitted some shims to eliminate play which allowed the hinge to provide support and also prevent any rain ingress. Overall i do like the quality and the design of the doors, particularly the adjustable door stays and the espagnolette. It's been a few months now since installing and with some of the bad weather it has proven to be a good investment.
