Choosing mortar for a chimney repoint

Tuckpointing and repointing on your estimate

Federal preservation guidance notes that repointing is the accurate name for replacing deteriorated mortar, and that tuckpointing strictly describes a decorative raised joint. In everyday use, the two words usually describe the same chimney job.

What matters is what the estimate says will happen. It should name the faces and joints included, how deep the old mortar will be removed and what the new mortar is meant to match. We write it that way, whichever word you used when you called.

Testing chimney joints by light scraping

Looking at a joint tells part of the story. Brick industry guidance adds a simple test, which is scraping the mortar lightly with a metal tool. Sound mortar resists. Weak mortar powders or comes away in grains.

We scrape suspect joints across each face rather than judging by color alone. Some joints look fine and are soft underneath, while others look worn and are still firm. The test lets us draw the repointing boundary around mortar that has actually failed, not around joints that only look old.

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.

Earlier repointing that fell out of the joints

Strips of mortar lying on the roof are a common sign of repointing that did not last. Federal preservation guidance links this to poor joint preparation, where new mortar was laid into joints that were too shallow to hold it.

We look at what remains of the earlier work and how deep it went. The failed layer comes out and the joints are raked properly before refilling. If the old repair was sound but water is still reaching the joints, we look for that cause before repeating the work.

Repointing answers for Lauderdale Harbours

Is a stronger mortar better for my chimney?

No. Repointing mortar should be softer and more vapor-permeable than the brick, and no stronger than the original mortar. A mix that is too hard pushes stress into the brick and can damage its face.

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.

Does the workmanship warranty cover tuckpointing in Lauderdale Harbours?

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.
