Commonly Asked Questions

  • +
    How much do new windows cost?
    The cost of new windows is dependent on so many factors such as style and materials. Many websites do offer lists of prices of their double glazed windows, but these are usually the cost for a basic off-the-shelf window and often without the cost of installation. At Everest, our products are made-to-measure and customised to your taste and home, which is why you won't find a price online as there are too many contributing factors.

    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.
