    Hi folks,

    Got some trouble with a wall on my house and hoping someone can help on what to do. Not sure if this can be done just by looking at it but anyway here's a pic.

    So for some background: House was built in 1935 (central scotland). It's a downstairs wall right next to a chimney going all the way to the corner of the wall. When we moved in 4 years ago we got this room plastered then painted and put a wood burner in next to where this pic is shown. The house walls are standard 2 layers of bricks with an empty cavity (not insulated) and then pebbledashed and painted on the outside. No idea if there's a damp proof course or how I would find out.

    The paint started flaking like this about a year or 2 ago and just getting round to fixing it just now. One thing to note that might be relevant is that the white stuff in the pic where I've scraped off the paint tastes salty.

    If someone could point me in the right direction that would be brilliant.

    Thanks.

    Looks like damp coming in from the window. Is the window well sealed outside?

    Ah I think you might be right, the window isn't in the best of states, particularly the stone frame. Here's a pic

    As above, there is a problem around the window stone reveals but your pic only shows damp damage on one side of the window - although both reveals show peeling paint?

    The lower rail on the window frame is not projecting over the stone sill and relies on a strip of glued on PVC which, in turn, has been sealed with some grey painted silicone.

    Is there a drip throating below the stone sill?
    There is also a render crack lower right of the sill.
    Examine the stone sill for cracks.

    If you can stand back and give a context to the outside of the whole w/frame, and similar for the wall inside the room?

    In the meantime remove all silicone sealing - then re-seal.
    Remove all the grey reveal paint - examine why the stonework was painted in the first place?

    Inside remove all damaged plaster back to brick and then post a pic.
