Bricking up a fireplace

[brokly]

I want to fill in a fireplace and plaster over it but the chimney is still a working one. I remember hearing somewhere that if this was the case you had to leave some sort of ventilation hole. Is this true?

The fireplaces in our bedrooms were bricked up & plastered over before we moved into this house. The chimney breasts have neat vents on each one.

We have two open Victorian fireplaces in use downstairs, but we don't get any fumes from the coal/logs, coming up into the bedrooms from them.

Hope this helps.

To cut a long story short - yes.  The chimney must also be caped to prevent the rain getting in

What do mean by the statement 'it is still a working chimney' ?

If you are bricking up an upstairs opening and still use the downstairs fireplace, then the chances are that they are seperate flues up to the roof. But you must fit a vent - a small plastic grille or airbrick in the fireplace you are bricking up.

Hi BillyNoMates (what a sad name) I'll be your friend!

Although your reply was probably referring to brokly's 'working chimney', but I thought I'd better mention that our upstairs bedroom fireplaces were 'bricked up' & plastered over, but only at the fronts of them & level with the walls. There is still a void behind the bricks, hence the air vents that have been fitted.
