    This is happening on 2 different windows in 2 different walls. 1 wall has just been silicone rendered the other repointed brick with lime mortar.

    The windows have the cavity open so you can see the inside of the external brick wall from inside the house.

    The water is coming in on top of stone in a small puddle on either side of the window. It is coming in where the brick work meets the stone and I have no idea why're how to stop it?

    Cut out the sealant where the window frame touches the window sill, and rake out any crap that's residing there. Allow it all to dry before reapplying some quality silicone, pushing it well in.
    The same applies where the render meets the window at the sides too.....if there is any gap at all, the water will get in.
    Cheers for the pics!
    John :)

    Doesn't seem to be any drainage to the front of window based on the pics shown
    If this is the case the window will be draining from underneath (base drain) that's where your problem lies.

    The window has been designed to drain out over a PVC cill.
    You need to block the drainage in the bottom of the frame which means taking the window out blocking up the holes and then drilling new drainage holes in the front.

    To be honest from the state of that window and as the inside is all stripped out it might just be better to get a new window.

    Okay that makes sense, we where thinking of getting the rendered window replaced.

    But the brick window is only 6 months old and is doing the same thing, I don't think the problem is th window on the brick one as the water goes along the length of the stone (where it meets the brick) then stops at the window, it does this on both sides of the window.

    Can you post a pic of the outside of that window too? If its only 6 months old it should be well in guarantee so the fitters should come and sort it that one out.
