Crumbling Bricks

~ My Old House ~ 3 Comments

Little of the interior brickwork is visible, except in the loft & cellar — alarmingly, the brickwork in the loft is crumbling away.

The chimney stack was replaced (roughly thirty years ago), and rebuilt using modern brick. The bricks below it, however, are nearly two hundred years old and are slowly turning to crumbs.

The brickwork on the party wall is scarcely any better. One brick has a hole through which the interior of nextdoor’s flue is visible.

I’m really not at all sure what to do about this…

Black Stuff…

The previous owner coated the gable wall with a black substance, perhaps something like bitumen or tar, no doubt as weatherproofing.

Since old buildings are meant to ‘breathe’, this ought to be removed.

This will require scaffolding: if the pointing is indeed to be raked out and redone, then clearly it would make sense to do both jobs together, along with any other work that requires scaffolding. …Such as removing those unsightly modern PVC barge-boards.

Pointing

~ My Old House ~ Leave a comment

The house has been re-pointed with cement mortar. This is unsuitable for old properties and will over time cause bricks to spall. Ideally, lime mortar should be used on period brickwork

However, removing (‘raking out’) cement mortar in order to re-point using lime may itself cause damage to the brickwork.

…So my dilemma: to rake out and re-point or not?
