Cornerstone did some repointing work for us as well as replacing three lintels and installing a new metal chimney cap. We were really happy with the quality of the work. Since the house is older, an exact colour match for the brick was not available, but they found the right texture and then tinted it so that it was indistinguishable from the original brick. They were always really professional: they started the work when they said they would, finished on time, and cleaned up everything afterwards. I highly recommend them for brick work.
