What good tuckpointing looks like
A clean, square cut behind each joint
How a joint is cut out matters as much as how deep it goes. Federal preservation guidance asks for old mortar to come away cleanly, with the back of each cut left square rather than rounded. A rounded or V-shaped cavity gives new mortar less to grip.
We clear each joint so the new mortar meets clean brick surfaces on both sides. That is slower than running a tool down the middle of the joint. It is also what lets the repointed mortar lock into place instead of sitting in a shallow groove.
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.
Chimneys that carry several earlier repairs
Some chimneys show joints from several past repairs, each a different color and hardness. Tell us what you know about that history, even roughly. It helps explain why some joints have failed and others have not.
We check which repairs are sound and which are coming away. Very hard patches may be causing damage to the brick beside them. We explain whether the new work should follow the original mortar, blend several patches or reset a whole face so the repairs stop showing.
Why raking chimney joints yourself is risky
Raking joints looks simple and is easy to get wrong. A grinder in inexperienced hands can cut brick edges and head joints, and the damage is permanent. Working on a roof or ladder adds real risk of a fall.
If you want to understand the job first, the free inspection is a safe way to do it. We explain what the joints need and how we would approach them. You can then decide how to proceed, with an accurate picture of the work and its risks.

Chimney joint work, questions and answers
How deep are the old joints raked out?
Deep enough to reach sound mortar, to an even depth that relates to the joint width, as brick industry guidance describes. Shallow raking leaves new mortar too thin to hold, which is one reason earlier repointing sometimes falls out.
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.
Should the chimney be waterproofed after repointing in Oakland Park?
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.
