1916 mid-Terrace.
Four internal chimneys - rear ground floor in use, front ground floor & two first floors not in use. Chimney "balloons" fitted.
Front ground floor chimney has white furr inside, bubbled paint outside up to 60cm from floor. Moisture meter measures 20-30% in these areas.
1st floor ceiling has small yellow/brown damp patch which measures 20-30%
Chimney breast in loft is measuring 20%, cement seems crumbly in places, but no furr or mould.
However, roof and chimney were renewed approx 7 yrs ago.
Is all this probably caused by a problem with chimney pointing/flashing/leading/etc ?
