Sealing Chimney

[Yanni]

I have closed( bricked) all the fires in the house. I'm just wondering how do I effectively seal the flue and disable the chimney all together ?

If I seal the flue, do I still need to install a ground brick at ground floor level by chimney breast to allow ventilation ?

Finally, If there are two chimney breasts downstairs, one for kitchen, one for lounge, if an brick needs to be installed, do I need an air brick in both chimney breasts or just one will allow the breasts to adequately ventilate ?

I'm trying to avoid installing air bricks for aesthetic purposes...

Best thing to do with a non-used chimney is to knock it down to below roof level and tile /slate it over.

Failing that drastic option you should cap the flue with a vented cap. You should also consider coating the outer brickwork of the chimney as it will soak up the water and let it out further down as the chimney isn't heating up to dry it out again.

Can't answer about the airbricks but I'm sure others on here will comment on that.
