"I live in an old Victorian house which had an outside coal house and toilet. My husband made the coal house into a porch and altered the toilet to indoors. It was always cold and damp in the winter with running walls. I saw your tiling packs in Wilkinson's and I have done the walls with them. I can't believe the difference they have made - no damp walls and much warmer. I am 79 so if I can do it anyone can - so easy!"
