We used sashed about 18 months ago to replace all the windows in our Victorian house. They are not cheap, but worth every penny spent. From start to finish, excellent customer service, no problems, superb communication. I do really appreciate their honestly and flexibility. They designed, confirmed drawings, put the windows for production, delivered and fitted them, as others said on here: punctual, quiet, clean, left our house with amazing windows. Called them again now, 18 months later, and the my came 2 days later to fix a slight problem with one of the front casement windows. Thoroughly recommend them.
