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

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.
