I'm really pleased with Sash Smart Ltd and have recommended them other friends who have used them and were also very happy with them. The windows are fantastic, I have had no problems with them. They are really well made and the service they provide from the quote to installation was fantastic. They were also kind enough to visit my property two years later to adjust the springs to stop the windows from sliding a little for free. I went for the triple glazed windows and have been really pleased with them and I'm glad I went with Sash Smart, very good value for money.
