we need to replace the upvc windows in our Edwardian (1908) home as they are almost 20 years old and starting to fail. I'm contemplating putting upvc sash windows in at the front, in keeping with the style of what the house would have had originally. We'll put regular double glazing at the rear the property, in part because that side of the house is not typically edwardian in style and also because of the cost.
Those of you who have upvc sash windows - are they worth it? Anything you wish you had known before going ahead or things I should look out for as we start getting quotes?
