How much do new windows cost?

How long do windows last?

There is no reason why quality windows can’t last for the lifetime of the property if well maintained. However, not all windows are created equally, for example timber windows will require some maintenance to maintain paintwork. Invariably this comes down to personal preference lower quality windows for example may have no gas between the panes limiting their effectiveness at reducing warmth in a room. Others may use poor quality seals which perish and result in draughts after around 10 years.
