We are over halfway through refurbishing a 1937 built house.
We have a damp patch by the chimney and to the left side which does dry out but returns after rain.
Our builder found a split in the lead flashing and a dent in the flashing the goes up the tiles and the problem still exists he also did some waterproof rendering up to the tray.
It has been suggested the the chimney stack would need to be taken down and reconstructed but we are not convinced that this will be the answer.
We would appreciate some advise
