I wanted to recommend Keith Burgess who's recently done some repointing and brickwork repairs for me. It was a very reasonable price, Keith worked quickly and was very tidy. He even came back a few days later to apply a water-repellent seal to a particularly porous area of the wall at no additional cost. Keith has a load of other recommendations on the forum, which is where I got his details. His number is: 07973 635035.
