Masonry St Louis - Tuckpointing

Masonry St Louis

Tuckpointing is a term a lot of homeowners hear without fully understanding what it means, so it's worth explaining plainly. Tuckpointing is the process of removing deteriorated mortar from between bricks and replacing it with fresh mortar, restoring both the structural integrity and appearance of a brick wall.

Mortar is designed to wear out before brick does. It's a softer material than brick, and that's intentional, since mortar is meant to be the part of a wall that gets replaced over time rather than the brick itself, which is far more expensive and difficult to repair or replace. Over decades of exposure to weather, particularly the freeze-thaw cycles common in St. Louis winters, mortar joints crack, crumble, and eventually fail.

Satisfied Clients

Our home is over 90 years old with original brickwork that had started crumbling in a few spots, and Masonry St. Louis handled the tuckpointing beautifully. They matched the mortar color almost perfectly and explained exactly what was causing the deterioration before starting any work. A year later everything looks solid, and we finally stopped worrying about water getting into the walls. Would absolutely hire them again for any future masonry work.

We hired Masonry St. Louis to build a retaining wall after years of dealing with drainage issues in our backyard. They were upfront about cost and explained the whole process clearly before starting, and the crew finished the job on schedule. It's held up through a full winter of freeze-thaw cycles with no cracking or shifting at all. Neighbors have already asked who did the work.

Tuckpointing matters because failing mortar isn't just a cosmetic issue. Once mortar joints deteriorate enough, water gets behind the brick face, and that water causes far more expensive damage over time, including spalling brick and, eventually, structural instability in the wall. Addressing deteriorated mortar before it reaches that point is significantly cheaper and less disruptive than waiting until brick itself needs repair or replacement.

The process starts with grinding out old, deteriorated mortar to an appropriate depth, being careful not to damage the surrounding brick in the process. New mortar is then packed into the joints and finished to match the original joint profile and style. Getting the mortar mix right matters as much as the application technique, since mortar that's too hard for the surrounding brick can actually cause the brick itself to crack under stress, particularly in older buildings constructed with softer, more porous brick common in this region.

Tuckpointing is needed when mortar joints show visible cracking, crumbling, or gaps, or when you can scrape mortar out of a joint with a finger or simple tool without much resistance. It's routine maintenance for older brick buildings, not a sign that something has gone catastrophically wrong, though the longer it's put off, the more likely it is that brick damage will follow.

If you've noticed deteriorating mortar joints on your home or business, tuckpointing now is almost always more affordable than waiting until brick repair becomes necessary as well. Contact us for an assessment and an honest recommendation.
