Had a few bricks come out from the window opening and have kept them aside for any repairs. A good weekend job. Need to replace these two bricks. This looks like where the old waste pipe was for the bath. Bricks removed using drill and recip saw with brick blade. A length of galvanized pipe was pulled out from behind the bricks which would have been the waste for the bath. First brick being placed in. Sprayed water on surrounding bricks to dampen down. Used level to make sure brick in flush and plum with wall. Second brick replaced, had to be trimmed down to fit using bolster. All pointed using jointing tool and brushed when firm to remove edges.
