Chimneys & Fireplaces Question
Blocked chimney flue
In the property I have just bought, I have found that the chimney flue has been completely blocked at the bottom for 8 years while the top has remained open. Can I expect significant problems with damp or damage to the brickwork of the chimney?
I have since added an air brick at the bottom of the chimney and intend to cap the top to prevent rain getting through to the fireplace. Is this the right course of action?
no, fit a new vent to the top of the chimney stack flue on the one not in use so any damp that gets into the flue can evaporate naturally by air flowing up and down the flue, if the flue was capped at the top of the stack this could cause dampness as the flue cannot be vented properly
