Hello,

Is it normal for exterior brickwork to have tiny cracks in the bricks.
Quite a few of my bricks have these tiny cracks about an inch long and
less that 1mm wide. The house is about 45 years old.

Is this just what happens to aged bricks?

Sorry if this is a daft question but I have nothing else to worry about
tonight!

Thanks,

If they are regularly spaced it may be an intended finish. Bricks come
in many different sorts as regards strength, permeability and frost
proof.
Really need a picture to get some idea.

I have a couple of hundred reclaimed Victorian yellow stock bricks stacked
up ready to build a garden wall. Some have quite wide cracks which don't
even extend to the edges of the brick, suggesting that they were made that
way. It's obvious from the general shape and size variation that
manufacture was a bit rough and ready in those days.

And the lime mortar helped them get away with it: I dug up quite a handy
few, from our 'lawn' which is on the site of Victorian greenhouses. The
mortar was quite cheesy but amazingly difficult to scrape off, but I expect
they would all soon break with cement type mortar.
