Hi All
Me again seeking the usual superb advice I see on here. Grade 2 listed 3 story mid terrace, 1840's, welsh slate.. I have a chimney breast that runs down what was the back wall of house, but is now in the middle of an outrigger ie two story extension tacked onto back of house in 1890 ish.
In the ground floor kitchen I have a damp patch that wnt dry after 4 weeks since reskimmed in gypsum. When I bought house all kitchen in back was gypsum having been done at least 40 years ago and this needed a skim. Chimney above all way to second floor roof is bone dry, wall below is bone dry. I took off air vent where fireplace was, bone dry, even dust soot at bottom so no water getting in there.
Im just confused why i have this single 3ft by 4 ft damp patch?
Any advice greatfully recieved
