    Vertical crack from upstairs window to downstairs window

    Vertical crack from upstairs window to downstairs window 4th Jan 18 at 11:32 PM
    The house has a vertical crack in the render running from the bottom of an upstairs window to the top of a downstairs window. Does anyone know why this might be?
    There is also some damp on the facing on the inside of the downstairs window, on the other side of the window from the external crack. And there is an indication (black marks) of damp on the outside wall running horizontally between the windows,
    Any advice would be greatly appreciated.

    How old is the house, how long ago was the rendering done, and how large is the crack?
    If it is a very narrow crack, i.e. 1mm it is probably just from the house settling and I probably wouldn't be too worried about it. If it is much larger or gets larger then I would start to worry.
    Doesn't sound like the damp is related, it could be from condensation or from a different issue with the window.
    If you're worried you could get a builder in to have a look, or a damp specialist and see what they say.

    It might just be a crack in the render - or it might be a structural crack. Only real way to find out is going to be to take the render off.

    Is the downstairs window quite wide?
    Does it have a lintel?

    My last house had a downstairs window which would have originally been wooden replaced with a upvc one. The weight of the bricks made the window dip a little in the middle. When we bought the house, the window needed replacing anyway so we put lintel in at the same time. It did not fix the crack but it prevented them getting any worse.
