I have just moved into a mid-terrace Victorian house (6months ago) that has two chimneys that aren’t being used. Both chimneys are completely blocked internally with what looks like absolute building rubbish - loose broken bricks and bits of wood. There are no signs of rising damp or anything like that, but I’ve noticed some soot is dropping through to the floor. The brick/rubble mix that’s blocking the chimneys looks quite fixed - they’re wedged in quite tight. Is this an immediate concern? Do I need to get the chimneys unblocked to prevent damp? This wasn’t flagged in our level 3 survey so haven’t thought to question it until now…
