Repointing chimney joints the careful way
What chimney tuckpointing work covers
Tuckpointing on a chimney means removing mortar that has worn, cracked or crumbled and packing new mortar into the prepared joints. The bricks stay where they are. The work restores the joints so they shed water and hold the masonry together as intended.
We explain the boundary of the job at the inspection. Joint work covers the mortar between sound bricks. A brick that has lost its face, a cracked crown or loose flashing each needs its own repair. Keeping those apart makes the estimate easier to follow.
Removing loose mortar deeper than the minimum
Sometimes the mortar is loose well past the usual raking depth. Federal preservation guidance says any loose or disintegrated mortar beyond the minimum should also come out. New mortar packed over crumbling material will not hold.
Where joints are deep, they are filled in stages rather than in one thick pass. We explain if we find unusually deep failure, because it can point to water getting well into the wall. That finding may change the plan for the crown, cap or flashing above, which we discuss as separate items.
Damaged bricks uncovered during raking
Raking out mortar sometimes shows that a brick is cracked through or has lost its face. Mortar packed around it does not restore the brick. That unit needs replacing, which is a different repair.
When that happens, we stop and show you the brick. We explain whether it can wait or needs replacing now, and price it as a separate item. The repointing continues on the agreed joints. Nothing is added to the job without your approval, however small the extra work looks.
Plants rooted in the chimney joints
Seedlings and vines can take root in failed mortar. Their roots can widen the joints and hold moisture against the brick. Brick industry maintenance guidance advises cutting vines away rather than pulling them, because pulling can tear brick and mortar from the wall.
We cut back growth before raking and remove what is left in the joints once it has dried. Any mortar loosened by roots is raked out with the rest. If plants keep returning, it can mean water is lingering, and we explain where that water may be coming from.

Answers about chimney repointing
Will the new mortar match the color of the old joints?
We aim for a close match by choosing the sand and, where needed, a pigment, then comparing samples wet and dry against the existing joints. New mortar often looks brighter at first and settles as it weathers.
Should the chimney be waterproofed after repointing in Seven Isles?
Not straight away. The brick industry's advice on clear coatings is to wait several months after repairs, because the repairs often stop the water on their own. A repellent after that is a separate item.
Does the workmanship warranty cover tuckpointing in Seven Isles?
Yes. The joints we renew under the agreed scope carry our workmanship warranty. The written record lists the faces and areas repointed, which helps if you notice anything about the chimney later on.
