Choosing mortar for a chimney repoint
Keeping the new mortar no stronger than the old
There is a second limit worth knowing. The brick industry's maintenance guidance says repointing mortar should be equal to or lower in strength than the original mortar in the wall. A stronger mix concentrates stress where mortar meets brick and can spall the brick face.
We look at the existing mortar, its hardness and how it has weathered before choosing the repair mix. Where the original is unusually soft, the new mortar has to respect that. We explain the choice in plain words and record it in the written record of the work.
Stepped cracks that follow the joints
A crack that zigzags up through the mortar joints can mean the chimney has moved. Brick industry maintenance guidance treats structural cracks as needing their own investigation rather than routine repointing. Filling them without knowing why they formed can hide ongoing movement.
We look at where the crack starts, how wide it is and whether bricks on either side have shifted. The same guidance lists stepped cracks among the signs of a structural issue, so we explain that the cause needs investigating first. Repointing is planned after that answer, not instead of it.
Film coatings over repointed brick
Some coatings form a film on the brick surface. Brick industry guidance on clear coatings explains that film formers can stop water getting in but also slow drying through the face. Moisture held behind the film can lead to clouding and spalling.
We do not recommend a film-forming coat over newly repointed brick. If your chimney already has one that is peeling, we explain how it affects the joint work and whether it should come off. Any coating decision is kept separate from the repointing itself.
Repointing every joint in an affected area
It is hard to tell exactly which joints let water in. Brick industry maintenance guidance therefore suggests repointing all the joints in the affected area rather than picking out single joints. A joint that looks sound beside failed ones may be next.
We mark the affected area and explain where its boundary falls. The boundary usually follows the damage and the way water moves across that face. Joints well outside it stay untouched. You see the marked area before approving, so the extent does not come as a surprise.

Tuckpointing questions from homes in Flagler Village
Does tuckpointing stop water getting into the chimney?
It can, when open joints are the path water takes. Water also enters through the crown, cap, flashing or cracked brick. We explain what the joints contribute, and when this job calls for a hose water test we tell you why.
Is face grouting an option for fine joint cracks?
Brick industry guidance describes surface grouting for small hairline cracks. It changes how joints look, making them a little wider and smoother. Repointing is generally recommended because it suits more kinds of joint damage, and we explain which fits yours.
Will you repoint the joints inside my firebox as well?
Firebox joints use refractory mortar and belong to firebox repair, a separate service. Chimney tuckpointing covers the exterior masonry. If both need work, each is priced on its own line so you can decide.
