Mortar joints are the unsung heroes of your exterior walls. They bind each brick or stone, manage moisture, and absorb small movements caused by temperature swings. When mortar erodes, cracks, or separates, water sneaks in, freeze-thaw damage accelerates, and the wall’s stability can suffer. The good news? With the right materials, technique, and timing, you can repoint—also called tuckpoint—mortar joints and restore both performance and curb appeal.
How do you know repointing is needed?
- Crumbly or recessed joints that sit behind the face of the brick.
- Hairline cracks along joints or at corners that collect dust or moss.
- Gaps between mortar and masonry units where you can see
