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,

Graham

From my geology lessons... I would say: "Do all the cracks line up so that
they are roughly parallel to each other from brick to brick, or are the
crack orientations fairly random?"

If fairly random, I'd say this was a rather sub optimum set of bricks and
those cracks could hold water and freeze and gradually lose their faces.

If all orientated the same way it could just be that they were all made
exactly the same way, but it may be that the whole structure is under stress
or strain from one direction.
