Choosing mortar for a chimney repoint
Why fast grinders can damage brick edges
A grinder can clear a joint quickly, and it can also chip brick corners and cut into the brick above or below. Federal preservation guidance warns that power saws used on thin brick joints almost always cause that damage. Once cut, the brick edge cannot be restored.
Damaged edges also make joints look wider than they are and leave thin, fragile mortar at the face. We keep grinders away from joints where they would harm the brick. If a power tool helps on some horizontal joints, final cleaning is still done by hand.
Curing care for freshly repointed joints
Fresh mortar that dries too quickly can chalk, bond poorly and weather early. Federal preservation guidance describes misting new joints lightly after tooling. It also suggests covering the work to keep it damp and out of direct sun, especially where mortar is lime-rich.
We plan curing care as part of the job, not as an afterthought. That may mean return misting, covers left in place or both. We explain what we will do and what you should leave alone, such as moving covers or hosing the chimney, while the new joints cure.
Joints at the roof line and the flashing
Where the chimney meets the roof, counter flashing is often set into a mortar joint. If that joint has failed, water can get behind the flashing. If the flashing itself is loose, water can reach the joints and brick below.
We look at both when the roof-line joints are in poor shape. Repointing covers the mortar. Re-forming or resetting the flashing is flashing work with its own line on the estimate. We explain how the two relate, so neither is fixed in a way that damages the other.
Damp brick where the chimney passes the attic
If you can see the chimney inside the attic, the brick there can offer clues. Damp patches, stains or loose grit on the attic side can mean water is working through the outer joints or coming from the top.
Mention what you have seen when you book. We look at the exterior joints and the chimney top with that in mind. The attic view helps us narrow the source. It also lets us explain whether repointing, a crown repair or flashing work is most likely to stop the water.

Tuckpointing questions from homes in Overtown
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.
What should I do to prepare for tuckpointing at my home?
Clear access to the chimney base, move vehicles away from that side of the house and keep pets indoors. Tell us about plants, vents or fragile roofing near the chimney. We handle protection and cleanup.
Do you test a small area before repointing the whole chimney?
On larger or visible jobs, a sample area confirms color, texture and profile before the rest proceeds. Brick industry and federal preservation guidance both recommend sample panels. We explain whether one suits your chimney.
