Repointing.
Replacing failed mortar at three-quarter inch depth, in a mortar matched to your original wall. Tested on a sample patch first.
Mortar is the part of the wall that fails. Brick, properly fired, lasts centuries. The mortar around it does not. When the joint recedes past about three-eighths of an inch from the brick face, water finds its way in. From there it spalls the brick face, freezes behind it, and quietly takes the wall apart from the inside.
Repointing removes the failed mortar to a depth of three-quarter inch — twice the joint width, the architectural standard — and replaces it with a mortar matched to your original in colour, hardness, and aggregate. We test the match on a small sample patch and confirm your approval before working the rest of the wall. Hand-tooled to the original profile. Warrantied for five years.
