Condensation in a redundant kitchen/bedroom chimney.

Postby Bigbuzz » Tue Nov 25, 2008 7:17 pm

We have recently purchased a victorian detached villa built around 1860.

We have damp on the chimney breast of our spare bedroom chimney. The chimney is split into 3, from left to right the first coming from the downstairs kitchen,which is unblocked where the arga once sat, second comes from the upstairs bedroom, unblocked but with an air brick part way up and the third is a small old cooker exhaust chimney which is blocked both ends and does not suffer any damp. however the upper walls on either side of the chimney and the internal ceiling to the front of the chimney are now suffering damp within the bedroom. A damp meter reading has been taken with a result of 100% damp

The chimney stack stops approximately three feet within the roof from the bedroom ceiling and remains open and not capped off and there is no damp in the loft, There is sufficient air bricks positioned within the loft space to allow for free flow of air circulation.The roof has been re tilled and felted, so we could be sure that the problem did not come from the roof.

The damp is across the chimney breast in the room from half way up on the left hand side (kitchen side) to the ceiling.

Has any one any ideas on how to solve this problem?
