Hi, I would love to recommend Steve and the boys from Sundial as well !! After allowing my nearly two hundred year old sash windows to become in need of some serious love and attention, they have brought them back to life. Steve uses real craftsmen to do the work and Eric and the boys were incredibly nice, professional and tidy. The windows look amazing, slide beautifully and the house has never been so warm and quiet. Highly, highly recommended !!
