Brick Cracks on Your Houston Home

Not every crack in your brickwork means the same thing. Understanding the type of crack can provide insight into how serious the issue might be:

Hairline Cracks: These extremely thin cracks, usually smaller than 1/8 inch wide, are often caused by minor settling or temperature changes. They typically aren’t a major concern, but if they start to widen, it’s wise to have them inspected to prevent bigger problems.

Vertical Cracks: Usually appearing due to natural settling, vertical cracks are less worrisome compared to other types. While they don’t always indicate major structural damage, keeping an eye on them and sealing them when necessary can help prevent water from seeping in.

Horizontal Cracks: These cracks can point to more serious foundation problems, as they often result from significant soil shifts or excessive pressure against the home’s foundation. If you notice horizontal cracks, especially along the mortar lines, it’s crucial to take action quickly.

Stair-Step Cracks: Recognizable by their zigzag pattern along the mortar joints, these cracks are common in areas where soil movement occurs. If they continue to widen or spread, they may indicate underlying foundation concerns that need professional attention.

Bulging or Bowing Cracks: When bricks push outward, it usually means there’s pressure from behind the wall. This can stem from foundation shifts or moisture trapped inside the wall. Addressing the issue sooner rather than later can help avoid more extensive repairs.

If you’ve noticed cracks in your brick walls, here’s a step-by-step guide on what to do next:

Monitor the Cracks: Keep an eye on the size and length of the cracks over a few months. Use a ruler to measure them and note any changes. If they grow significantly, it might indicate an underlying issue with your foundation that needs attention.

Check for Drainage Issues: Look around your home for signs of poor drainage, such as pooling water or downspouts that don’t direct water far from your foundation. Improving drainage can help stabilize the soil around your foundation, reducing movement.

Schedule a Foundation Inspection: For larger or growing cracks, especially horizontal or stair-step cracks, consider having a professional foundation inspection by us. We offer free inspections, and we can help you determine if foundation repairs are necessary.

Repair the Cracks: Small cracks can often be repaired with mortar or sealant to prevent water intrusion, which could worsen the issue. For larger cracks, consider hiring a masonry expert who can ensure the repairs are structurally sound.

Consult a Structural Engineer: If you’re concerned about significant foundation movement or bulging walls, consult a structural engineer. They can assess the full extent of any structural damage and recommend the appropriate course of action.

Completely avoiding cracks may not be possible, especially with Houston’s challenging climate and soil conditions, but there are ways to minimize the chances:

Keep Soil Moisture Consistent: To prevent excessive soil shrinkage during dry periods, using soaker hoses around your foundation can help maintain stable moisture levels and reduce the risk of shifting.

Enhance Drainage: Proper drainage is essential to prevent water buildup near your foundation. Ensure gutters and downspouts are functioning correctly and that the ground slopes away from your home to channel water away effectively.

Perform Routine Inspections: Regularly check areas prone to movement, such as door frames and windows, which may show early signs of foundation shifts. Catching minor issues early can help prevent bigger problems.

By recognizing what causes cracks and taking preventative actions, Houston homeowners can safeguard their property and avoid expensive repairs. If you spot cracks in your brickwork, there’s no need to panic—most can be fixed, and addressing them early helps maintain your home’s structure and value.
