Hi, first time post but in need of help!
We have an old chimney flue which leads down into our kitchen right above the cooker. Small bits of debris fall down it occasionally so we want to seal it off (or at least stop the debris falling into our food!).
Spoke to a builder about it and he's suggested sealing it off at the bottom, above the cooker. As the flue is capped at the top (but not sealed) he reckons that will be enough ventilation and there's no need to fit any airbricks at the bottom (in the kitchen, which admittedly will be generating warm moist air).
By question is whether this is OK? I'm concerned that one opening at the top of the chimeny might not be enough to ventilate the whole thing. Is it OK to seal the flue and just leave an opening at the top?
