We're having our bathroom renovated. Along the wall between the bathroom and the bedroom, where the plumber has channelled out a space for the new pipes, we've got cracks in the bedroom wall. The wall was reskimmed and painted a couple of months ago.... The builders/plumber are going to fix it, but I'm just wondering if I'm still going to be able to see where they've fixed it. Basically, none of the plaster has come off, but the top layer of paint/plaster has cracked all along the wall, and there are bit where the paint/plaster would come off if I knocked it too hard. We had the whole bedroom reskimmed and now I'm panicking that I'll be able to see this patched up bit forever. Can anyone relieve my fears?
