The craftsmanship and attention to detail that make Ottawa’s heritage buildings special require a skilled hand to restore. At Keystone Traditional Masonry, our skills include mortar colour matching, repointing with Heritage lime mortar mixes, stone and brick replacement, crack repair, and stone carving. An understanding of how Heritage buildings were built and what problems often arise, allows us to not only repair symptoms but instead to often solve problems so that they will not occur again.
