I am not in the trade so will try to explain. Please keep answers simple too!!
I live in a terraced house built in 1884 and due to the slope of the road, my house is one foot higher than next door. I got the exposed one foot of exposed gabling between our properties re-rendered last year due to damp coming through into the attic (now converted into a room) but this did not cure the problem. The damp is on the wall between our properties next to both front and rear chimneys that I also share with my neighbour.
Is it more likely that the mortar/render between the bricks of the chimney has worn allowing damp in, or that the flashing (horizontal) has gone? I doubt that any work has been done on the roof since it was built!
A builder has suggested a re-build for both chimneys - how much would this cost if there is such a thing as an average cost? The chimneys are about 5 feet high if that helps. Would they need to re-use the existing bricks, or use new ones.
I got both chimneys re-rendered last year as well ........ I thus though that they were watertight, or can rain penetrate new render?? I wonder if I could claim on the insuance?
I can't upload a photo as I am away on holiday - sorry!
