What Causes Brick and Mortar to Crumble?
Brick and mortar deterioration in DFW homes is one of the most common masonry issues in North Texas. The primary causes are water infiltration into mortar joints that freezes and expands during winter temperature drops, DFW's expansive clay soil causing foundation movement that stresses the brick veneer, age-related deterioration of original mortar which typically lasts 25 to 30 years before needing repointing, efflorescence which is the white powdery staining caused by water carrying mineral salts through the brick, and spalling where the brick face flakes or pops off due to moisture trapped inside the brick itself.
How Serious Is the Brick and Mortar Damage?
Low
Minor mortar joint erosion or efflorescence staining with no cracking. Tuckpointing recommended within 1 year to prevent water infiltration.
Medium
Crumbling mortar joints, spalling brick faces, or stair-step cracks in the mortar. Repair within 3 to 6 months to prevent water damage to the wall system.
High
Large sections of missing mortar, multiple spalled bricks, or cracks wider than 1/4 inch with displacement. Call a masonry contractor immediately — water is likely entering the wall.
Typical Brick and Mortar Repair Costs in DFW
| Repair Type | Average Cost | Notes |
|---|---|---|
| Tuckpointing (per linear foot) | $5 – $15 | Mortar joint repointing |
| Tuckpointing (average chimney) | $500 – $1,500 | Full chimney repoint |
| Spalled brick replacement (per brick) | $20 – $50 | Match existing brick color |
| Efflorescence cleaning and sealing | $300 – $800 | Per affected area |
| Brick veneer section repair | $500 – $2,500 | Depends on size of area |
| Full chimney rebuild | $2,000 – $8,000 | Above roofline |
Matching existing brick color and mortar color is one of the most challenging parts of masonry repair in DFW. Always ask to see color samples before work begins.
Can You Fix Brick and Mortar Yourself?
Minor tuckpointing on small areas is within reach for a patient DIYer with the right mortar mix and tools. The hardest part is matching the existing mortar color — premixed mortar from a hardware store rarely matches aged mortar. Efflorescence can be cleaned with a diluted muriatic acid solution but requires proper safety equipment. For anything beyond a few square feet of repointing or any structural cracking, hire a licensed masonry contractor. Poor mortar repairs can trap water and accelerate the damage.
What NOT to Do
- •
Do not use regular Portland cement to repoint brick — it is too hard and will crack the surrounding brick
- •
Do not paint over efflorescence staining without treating the source of moisture first
- •
Do not ignore crumbling mortar — water infiltration into the wall system causes far more expensive damage
- •
Do not pressure wash brick without understanding the age and hardness of the brick — older soft brick can be destroyed by pressure washing
- •
Do not seal brick without ensuring all moisture has dried — trapping moisture inside accelerates spalling
When to Call a Masonry Contractor
Call a licensed masonry contractor when mortar joints are visibly eroded across a large area, when brick faces are spalling or popping off, when stair-step cracks appear in the mortar joints, or when you see water staining inside the home near an exterior brick wall. In DFW, masonry repairs are best done in spring or fall when temperatures allow proper mortar curing — avoid repairs during extreme heat or freezing temperatures.
Real Example: Fort Worth Homeowner
A homeowner in Fort Worth noticed white staining and some crumbling mortar around their chimney. They ignored it for two years. By the time they called Fort Worth Brick Repair the mortar had deteriorated enough to allow water into the chimney chase causing the interior drywall around the fireplace to develop mold. What would have been a $650 tuckpointing job became a $2,800 repair including mortar work and interior mold remediation. Address masonry deterioration early — it only gets worse.
