Deteriorated Mortar Joints
Mortar joints are an important part of brick and masonry construction, but exposure to moisture, weather and age can cause them to crack, loosen, recede or break down over time. As mortar deteriorates, open and weakened joints can allow moisture deeper into the masonry and leave surrounding brick more vulnerable to damage.
Removing & Replacing Mortar
Repointing involves removing deteriorated mortar to the appropriate depth and installing new mortar within the joint—not simply covering failing joints with a thin layer of new material.
Mortar Compatibility
The replacement mortar should be appropriate for the existing brick and masonry. Older and historic construction may require softer, compatible, lime-based mortar rather than harder modern mortar that can contribute to damage in older brick.
