The top layer of bricks on the wall surrounding our flats, built in
2003, has started to spall due to the freezing weather last winter and
probably the wrong bricks used by the builder.
The builder and NHBC have both denied any responsibility and it is
down to us to solve the problem as economically as possible. Court
action would probably be expensive and futile.
We could of course have all the top layer removed and replaced by the
correct type of brick, but does anyone have a cheaper solution?
The wall is about 300 metres long.

NHBC wont give a **** because it's not structural.

I would doubt there is any other option than replacing the wrong bricks with
the correct ones.
