Here’s the design secret of masonry: mortar is meant to be the weak link. It’s engineered softer than brick so that weather, movement, and time eat the joints, the replaceable part, instead of the units. Tuckpointing is simply honoring that design: renewing the sacrificial layer on schedule.
What the work actually involves
The test that answers “do I need it?”
Take a house key to a few joints at eye level: solid mortar resists and barely marks, you’re fine. Powdering, scratching out sand and dust, means the binder has failed and the erosion clock is running. Receded, joints sitting visibly behind the brick face, or missing chunks: the window is fully open, and every rain is now reaching brick edges and cores, feeding the spalling cycle.
Where it fits in the bigger picture
Joints fail first at the weather-beaten top courses and on the storm-facing side, a routine inspection maps the actual extent, which is often less than homeowners fear and more than they can see from the ground. Done in its window, tuckpointing is mid-priced, decades-durable maintenance; skipped past the window, it hands off to brick replacement and eventually the rebuild conversation. Get the joints mapped.
