Question 1

What causes brick mortar to crumble or crack?

Accepted Answer

Mortar crumbling is primarily caused by age (mortar typically lasts 25–50 years), water infiltration, freeze-thaw cycles, foundation movement shifting the brick veneer, and using the wrong mortar type during a past repair. In DFW, foundation movement from clay soil expansion is a significant contributor.

Question 2

Is crumbling brick mortar a serious structural problem?

Accepted Answer

Mortar damage on brick veneer is not an immediate structural emergency since the brick is not load-bearing, but it allows water infiltration that can damage wall sheathing and framing over time. Wide cracks or displaced bricks indicating foundation movement should be evaluated by both a masonry contractor and a foundation specialist.

Question 3

What does tuckpointing and masonry repair cost in DFW?

Accepted Answer

Tuckpointing in DFW costs $5–$25 per square foot depending on access and damage extent. Small chimney tuckpointing jobs run $300–$800. Larger brick veneer repairs average $1,000–$5,000. Full chimney rebuilds or major brick replacement projects can reach $8,000–$20,000.
