Brickwork is known for its durability and strength, but even the most solid brick structures can develop structural damage over time. Early detection of structural issues in brickwork is essential to maintaining the stability, safety, and beauty of your home. This guide will help you recognize the most common signs of structural damage in brickwork and provide advice on what to do if you spot any of these warning signs.
Why Structural Damage in Brickwork Matters
Brick structures rely on a stable foundation, strong mortar, and sound bricks to remain secure. Structural damage not only affects the appearance of brick walls but can also compromise the stability of the entire structure if left untreated. Identifying damage early allows you to address the root cause before it becomes a costly repair. Below we'll discuss the common signs of structural damage you'll see in masonry brickwork:

Here are the common visual signs of structural damage you'll find in brickwork.
1. Cracks in the Brickwork
What to Look For:
Cracks in brickwork are often the first sign of structural damage. Pay attention to:
- Stair-Step Cracks: These cracks follow the mortar joints in a step-like pattern, often indicating foundation settling or movement.
- Vertical Cracks: Long, vertical cracks can suggest foundation settlement or pressure from shifting soil.
- Horizontal Cracks: Horizontal cracks are usually more serious and can signal severe structural pressure, particularly in basement walls.
What to Do:
If you notice large or widening cracks, consult a masonry professional. Stair-step and horizontal cracks, in particular, can indicate underlying foundation issues that need immediate attention.
2. Bulging or Bowing Walls
What to Look For:
Bowing or bulging walls appear when sections of the brick wall push outward or inward. This is often caused by water infiltration or foundation movement, which places pressure on the wall.
What to Do:
Bowing walls are a serious issue that can lead to structural failure if left unaddressed. Contact a professional mason or structural engineer as soon as possible to assess and stabilize the wall.
3. Loose or Shifting Bricks
What to Look For:
Loose bricks that shift or move when touched indicate weakened mortar or underlying structural issues. Bricks may become loose due to mortar deterioration, water damage, or foundation instability.
What to Do:
Loose bricks can typically be re-secured through repointing or replacing damaged bricks, but if the problem is widespread, it may indicate a larger structural issue requiring a professional inspection.
4. Gaps Between Bricks and Windows or Doors
What to Look For:
If you notice gaps between the brickwork and window or door frames, this could indicate foundation movement or settling. Shifting foundations can cause the walls to move independently, creating visible gaps around frames.
What to Do:
Gaps around windows and doors can allow water and drafts into the home. While caulking may provide a temporary fix, it’s essential to address the underlying cause by consulting a masonry or foundation expert.
5. Deteriorating Mortar (Crumbling or Eroded Mortar Joints)
What to Look For:
Mortar binds bricks together, and deteriorating or crumbling mortar is a sign that the structural integrity of the wall may be compromised. Damaged mortar joints are often caused by moisture exposure and weathering.
What to Do:
Repointing, the process of removing and replacing deteriorated mortar, can restore stability to the wall. Regular maintenance of mortar joints is essential to prevent structural issues and protecting against water damage.
6. Efflorescence (White Powder on the Brick Surface)
What to Look For:
Efflorescence is a white, powdery residue on the brick surface caused by salt deposits left behind when water evaporates. While not a structural issue in itself, efflorescence can indicate moisture infiltration, which can weaken bricks and mortar over time.
What to Do:
Address any sources of moisture around the brickwork, such as faulty gutters, downspouts, or drainage issues. Removing efflorescence with a gentle brush or water wash can help maintain the appearance, but solving the moisture problem is key to preventing further issues.
7. Discoloration or Staining on Brickwork
What to Look For:
Dark spots, streaks, or green patches on brickwork can indicate moisture absorption or mold growth, which can lead to deterioration over time. Discoloration may also suggest water pooling near the foundation or leaking from gutters.
What to Do:
Clean any surface mold and repair any drainage or gutter issues contributing to water exposure. Sealing brickwork with a breathable water-repellent can help prevent future discoloration and protect against moisture damage.
8. Sagging or Misaligned Bricks
What to Look For:
Sagging or misaligned bricks may appear when there’s significant structural stress on the wall, often due to foundation settlement or shifting soil. This can create uneven lines or distorted shapes in the brickwork.
What to Do:
Sagging or misalignment is usually a sign of a larger structural problem. Contact a professional to assess the foundation and recommend solutions to stabilize the wall.
9. Cracks or Damage in Interior Walls
What to Look For:
Cracks in interior walls, especially those near windows, doors, or corners, can indicate that foundation issues are affecting your brickwork. Cracks in drywall or plaster may suggest that the home’s structure is shifting.
What to Do:
If you notice interior cracks alongside exterior brick damage, consult a structural engineer or masonry expert. Interior cracks combined with brick damage may indicate foundation problems that need immediate attention.
Why Regular Inspections Matter
Scheduling regular masonry inspections is one of the best ways to catch early signs of structural damage. Professional inspections can help identify issues that may not be visible to the untrained eye, allowing you to address problems before they worsen. For older homes or buildings in regions prone to extreme weather, annual inspections are especially important to ensure the longevity and safety of the brickwork.
When to Call a Professional
While minor cracks or discoloration may not require urgent repair, certain signs of structural damage should be addressed by a professional as soon as possible. Here are some instances when you should consider contacting a masonry expert or structural engineer:
- Large, widening cracks in the brickwork
- Bowing or bulging walls
- Gaps around doors and windows
- Loose bricks or crumbling mortar
- Signs of foundation settlement
A professional mason or structural engineer can assess the extent of the damage, determine the underlying cause, and recommend an effective solution to prevent further issues.
Final Thoughts
Knowing the signs of structural damage in brickwork allows you to take a proactive approach to home maintenance, protecting both the appearance and safety of your property. Regular inspections and timely repairs can extend the life of your brickwork, reduce the risk of major structural issues, and save on costly repairs in the long run. If you suspect structural damage in your brickwork, don’t hesitate to reach out to a professional for an assessment. Taking action now can help keep your home safe, secure, and beautiful for years to come.
