Terms of the Trade: What Is Repointing? Terms of the Trade: What Is Repointing?

Repointing is the process of removing mortar from exterior joints in masonry construction, known as pointing, and replacing it with fresh mortar to offer renewed strength. Over time, weathering can allow for moisture to permeate the pointing, causing damage. Sometimes during repointing, existing mortar is removed before the new layer is added, and other times it's left to serve as a base for the fresh coat.
