A big thankyou to Mark form Vision Double Glazing for transforming the rooms in our house where we had new windows and doors installed. The whole ambience of some rooms has totally changed. The difference is unbelievable. The Windows and doors are excellent quality and the workmanship is fantastic. Mark is very knowledgeable and enthusiastic about the product and takes extreme pride in his workmanship. The extra finishing touches make the difference between a good job and an exceptional one. Mark is very punctual, which is very refreshing as there is nothing worse than having to wait around for workman. With Marks attention to detail we would call him a craftsman. When Mark left, he had cleaned up inside and out, of course. It was an absolute pleasure working with Mark and we would highly recommend him. Irene and Norman - Duncraig, WA
