    I have an old chimney stack up from the kitchen and through to the bathroom. The kitchen stack part has already been removed (before we moved in), the bathroom stack is still there, not ventilated and was - i think - responsible for a big damp patch coming out on the adjoining bedroom wall. I broke the stack open to try and fix the damp problem. It was bone dry but bricks covered in Soot which apparently sucks the moisturein and through the wall.

    So I need to fill it in and seal it off. It is part of the external wall and the back wall of the chimney is now only one brick width thick. We have solid non-cavity walls - 2 bricks thick.

    I am thinking to use poly beads, then board it off. My dad says brick it up..

    So 2 questions.

    1. which method is best/necessary to fill it in?
    2. do i need to scrape off the layer of Soot before filling it in? or will filling it in stop the damp air being sucked through?
