damp on chimney breast

[273gloria]

Hi all

Please can someone help this chimney is driving me mad.

I bought my 1st home last year and noticed when it rained that a massive damp patch occured at the bottom of the chimney breast on the ground floor, the chimney is in the centre of the house, not on an external wall. The patch stays there but will eventually dry out, the plaster becomes chalky. I obviously presumed this was due to a leak from the chimney and paid £400 for a roofer who agreed that was the problem to fix the chimney. Well 4 months on, it rained 3 days ago a to my despair i noticed this bloody patch again, seem to have got higher now. Only other info I can give is that the floors are concrete,
Have no idea what direction to go in now. ANy info would be so great,
Thanks a woman in despair!!!

What did the roofer do for his £400?
is the vent in use?

he said he repaired some brick work, flashing, and pointed the sides? does that sound about right?

Ive no idea about the vent to be honest.

Ive no idea about the vent to be honest.

Is the vent serving the fire in use? ie gas, solid fuel.

sounds like water ingress through the vent.

yes the vent would still be in use for my gas fire.

Have you any idea of the type of cap being used on top of the stack for the flue? and if you have a flue liner. sorry about the questions but they are all relevant.
Or if you can post a pic of the chimney stack.
