We've got a couple of companies coming round this week to quote for new double glazing in upstairs and downstairs bay windows. Each bay has three fairly large windows (about 2 metres high each). Could those who have had it done give me an indication of what sort of price they've paid, as I understand double glazing is the type of industry where they quote sky high prices that you really have to haggle down? Also, we'll be getting quotes for regular and sash windows, so experience of either type is appreciated, thanks
