Damp patches, upstairs only, appearing on chimney breast after wet and windy spells - the chimney is not sealed off and there is a gas fire which we disconnected and was not regularly used. After the problem started we had some repointing on stack, and the cement bedding where the pot sits redone.
After this work the problem came back worse - our roofer is not sure why - he thinks the flashing is ok.
I got a second opinion - a builder who thought it would be the flashing but when he got up there he couldn't see an issue with flashing - he has suggested it may be the London tudor brick failing and holding damp and is talking about rebuilding whole stack with engineering brick!
No obvious signs of damp in adjoining attic roof (breast is just to the side so not inspectable from attic)
1. Is this correct about the brick holding damp? - house is built 1980 - seems unlikely to me and more like ingress but I'm not a builder
2,. Could it be an unseen issue on roof getting under flashing? Nobody has lifted roof tiles to inspect
3. Could it be coming in through pot? But there is no sign downstairs by fireplace
Thanks for input
upstairs -it's similar all around chimney breast - nothing downstairs by fireplace
chimney before repointing and redoing cement on top
chimney after cementing top and repointing -same pot was put back after this pic was taken
