Hi, we live in a terraced house, with an entry/ginnel between the two houses. We have discovered this wall is a single brick wall. Therfore the living room is extremely cold because of this wall, and we are getting black mold, presumably because of condensation. Would appreciate any advice on any cheap methods to make the room warmer (FYI, its only colder downstairs because the houses are joined at the top). Hope this makes sense.
Thanks in advance
Graham
