From raking to tooling, the repointing sequence
Using mortar within its working time
Once mortar starts to set, adding water to loosen it again weakens it. Federal preservation guidance says repointing mortar should be used within its working time and not retempered. Old mortar in the pan is discarded, not revived.
We mix batches sized to what can be placed while the mortar is fresh. That keeps every joint filled with mortar at its intended strength. It also keeps the color more even across the chimney, because each batch goes into the wall at the same stage.
Joint profiles that help a chimney shed water
The shape of a finished joint matters on a chimney that takes weather on every side. Brick industry guidance says concave, V-shaped and grapevine joints best resist water on exterior brick, because tooling presses the mortar tight against the units.
If your chimney already has one of those profiles, we match it. If it has a profile that holds water, we explain the trade-off between matching the existing look and improving how the joints shed rain. You decide, and the estimate records the profile chosen.
Scheduling repointing with roof and crown work
Joint work often sits alongside other jobs at the top of the house. Federal preservation guidance suggests scheduling related work so it does not interfere with repointing and so access set up once can serve both.
If the crown, cap or flashing needs work, we explain the sequence. Usually the source of water at the top is fixed before the joints below are repointed. If a roofer is coming, tell us the timing so the trades are not working over each other or damaging fresh work.
Repointing does more than tidy the chimney
Fresh joints make a chimney look cared for, but the real purpose is keeping water out. Brick industry guidance explains that repairing cracked or deteriorated joints restores the mortar at the face and reduces the water that enters the masonry.
That matters inside the chimney as much as outside. Less water in the brick can mean less staining, fewer white deposits and less damage to the top courses and the flue. We explain what the repointing is expected to change, so you can judge the work by more than its looks.

Tuckpointing questions from homes in Sandalfoot Cove
Can you repoint only the worst joints on the chimney?
Sometimes. Where damage is confined, spot repointing can be sensible. Brick industry guidance also suggests repointing every joint in an affected area, because it is hard to tell which joints admit water. We explain the boundary we recommend.
How long does new mortar take to cure?
Mortar hardens gradually and keeps gaining strength after it looks set. We keep new joints damp and shaded as needed and tell you what to avoid while it cures, such as washing the brick or using cleaners on it.
Should the chimney be waterproofed after repointing in Sandalfoot Cove?
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.
