Repointing means removing deteriorated mortar from the joints between bricks and packing in fresh mortar, restoring the wall’s water resistance. Tuckpointing is the finishing technique, a thin, precise line worked into the fresh mortar for a clean, uniform look, especially on older or decorative brickwork.
Why DFW chimneys need this sooner than the brick suggests
Original mortar on a lot of 1970s and 80s DFW homes was mixed softer than what is used today, and decades of Texas heat, UV exposure, and our freeze-thaw winters wear it down faster than the brick itself ages. It is common to find brick in genuinely good shape sitting in mortar joints that are crumbling or missing an inch deep, which is exactly the setup for water to start working behind the brick face.

Frequently asked questions
How is repointing different from just patching?
Patching covers a problem area on the surface. Repointing removes the failed mortar to a proper depth first, so the new mortar actually bonds and does the job the old joint used to do.
Will the new mortar match the color of my existing brick?
Yes, matching mortar color and texture is standard practice for us, especially on visible, street-facing chimneys where a mismatch would stand out.
Is tuckpointing just cosmetic, or does it matter structurally?
The repointing underneath is the structural, waterproofing part. Tuckpointing is the visual finish on top of that repointed joint, so both matter, just for different reasons.
How long does repointing last?
Done correctly with the right mortar mix, repointed joints typically last several decades, often outlasting the original mortar that was there before.
