Working with VDG has been a pleasure from start to finish. I needed to buy replacement windows for my renovation and not done so in a long time. I had read up on the benefits of double glazing and their increasing popularity in Europe and the USA. Mark was excellent in explaining the benefits of double glazing to me and was very proactive in answering questions in a friendly manner. The quote was clear and the pricing surprisingly competitive against standard Aluminium windows for the benefits you get. The windows arrived to the lead time quoted and were installed over a two day period. The finish of the job was exceptional, the construction looks very solid and robust, they look great and have brought the house to life. All done with a smile and attention to detail by Mark.
