    hi,
    I removed some UPVC trim that was yellowing from around a window.
    My intention is to replace it.

    However, it seems to of ripped a hole in the side of the wall (See photo)

    How can i repair it?
    There doesnt seem to be anything i can stick anything on to!

    Is that a cavity/void?

    If yes then how deep?

    If not too deep you could use expanding foam

    If very deep then use minimal expanding foam in a number of hits.

    Mask the window frame. Spray a mist of water onto the part of the frame in the cavity. Run a bead of foam, leave to harden then repeat, this time making the foam stick to the foam that has already stuck to the frame.

    When finished remove any foam that is proud of the wall, with a knife or sand paper and fill with red devil One time filler.

    It will always be weaker than the rest of the wall but it will suffice and resist cracking

    A better method would be to "glue" sheets of plasterboard over the recesses and then make good where they meet the internal walls

    I'd cut a neat rectangular hole in the plasterboard, about 8" wide, up to the height of the hole. I'd then fix a few pieces of timber so that i could screw a new piece of plasterboard into place,,, a much stronger job.

    hi roughcaster

    what will you fix the timber to?

    To be honest I can't work out why the cavity is there.

    very... like... the width of the wall
    Either side of the "hole" is bricks... i think.

    So they are cavity walls? Possibly without insulation?

    I would probably go for the expanding foam then given that you cant cut away for timber as roughcaster suggested.

    The foam would also have advantageous thermal properties.

    If you cut out more of the area, you might get a better idea of what you're looking at. The old board already on the wall must be fixed to something. If it's cut out towards the left, you might find an upright stud, from which you might be able to fix 2 or 3 horizontal noggins, to another upright piece of timber, jammed/fixed to the wall, on the opposite side of the hole, (beside the glazed door),, making a frame for the board to screw onto???

    Thornfield said the wall board is not plasterboard,,, what is it????

    Complete speculation here but I guess that the upvc was retro fitted and that the original wooden frames were thicker, meaning that the gap at the bottom of the image was initially small enough to wedge the plaster/render into.
