[quote="stoneyboy"]lyons,
If you are referring to the chimney hearth opening if the bricks above are laid flat you should fit a heavy metal flat to stablise the opening.

Thanks - yes flat bricks. How thick does the metal flat need to be - will 20 - 25 mm suffice? And as we are installing a wood stove (the other question you replied to) - will it be ok to have metal lintel above?
