Brick Exterior Maintenance
Why Brick Exteriors Need Maintenance
Brick exteriors may seem virtually invincible, but they’re not quite. While it’s true that bricks are generally durable and require less maintenance than other forms of cladding, they’re not entirely maintenance-free. Regular care can keep your brick exteriors looking their best and can save you from future repair costs.
Common Brick Problems That Require Maintenance
Efflorescence
Efflorescence is the white, powdery substance that sometimes forms on brick surfaces. It happens when water brings salts from the brick to the surface and then evaporates, leaving the salts behind. Over time, it can make your brickwork look aged and unsightly.
Brick Spalling
Spalling refers to the flaking or chipping of the brick’s surface. It can happen when water enters the brick, freezes, and then expands, causing the surface to flake off. Spalling can weaken the structure and, if left unattended, can lead to serious damage.
Mortar Decay
Bricks are typically much longer-lasting than the mortar that binds them together. Over time, exposure to the elements can lead to the mortar decaying or cracking, compromising the stability of the wall.
How to Maintain Your Brick Exteriors
Cleaning
Routine cleaning of your brick exterior can keep it looking fresh and vibrant. A popular method is pressure washing, but it can sometimes damage the bricks when used incorrectly. Simpler methods, like scrubbing with a mild detergent and a brush, can often suffice.
Applying Brick Sealer
To protect your bricks from water damage, you can apply a brick sealer. Sealing your brick exteriors can prevent moisture absorption and thus help prevent spalling and efflorescence.
Repointing
Repointing, or renewing the external part of mortar joints, helps maintain the structural integrity of your brickwork. It’s especially important when the existing mortar starts to fail due to age or weather exposure.
Brick Exterior Maintenance Checklist
| Task | Frequency | Notes |
|---|---|---|
| Inspect for Efflorescence and Spalling | Quarterly | More frequently in winter due to freeze-thaw cycles |
| Pressure Wash or Scrub Surface | Annually or Bi-Annually | Dependent on pollution level |
| Apply Brick Sealer | Every 5-10 years | Dependent on exposure to rain and humidity |
| Repoint Mortar | Every 25-50 years | Dependent on the quality of original mortar |

Maintenance Needs for Brick Structures
Unique Maintenance Considerations for Brick
Brick houses, known for their durability and aesthetics, still require regular maintenance to ensure longevity and structural integrity. Although the basics of masonry maintenance apply, brick buildings present some unique needs:
- Thermal Expansion and Contraction: Brick expands and contracts with temperature changes. Over time, this can cause stress on the structure, potentially leading to cracks or gaps, especially around windows and doors.
- Foundation Settling: As homes settle, bricks may shift subtly, affecting the structural alignment and requiring professional evaluation and adjustment.
- Chimney Stability: Brick chimneys often experience more wear due to exposure to the elements and heating cycles, necessitating regular inspections to avoid creosote build-up or mortar degradation.
Advanced Techniques and Tools
In addition to common maintenance practices, here are some advanced techniques for maintaining brick exteriors:
Masonry Veneer Suggestion
Masonry veneers offer a solution for updating the exterior appearance without replacing the entire wall. Veneers are thinner, offering a cost-effective option to refresh the look while maintaining the classic charm.
Infrared Thermography
Use infrared thermography to detect moisture prone areas in brick walls. This non-invasive method helps to identify areas that may lead to efflorescence or internal damage before it becomes visible.
Eco-Friendly Maintenance Options
Modern techniques favor environmentally sustainable practices:
- Biodegradable Cleaners: Clean your bricks using biodegradable detergents that are less harmful to the environment while still effectively removing dirt and grime.
- Eco-friendly Sealants: Choose sealants with low VOC (Volatile Organic Compounds) to maintain indoor air quality and reduce environmental impact during application.
Key Maintenance Challenges
| Challenge | Potential Impact | Solution |
|---|---|---|
| Thermal Movement | Cracking or Gapping | Flexible caulking at joints |
| Water Penetration | Structural Damage | Regular sealing and gutter maintenance |
| Foundation Settling | Brick Misalignment | Professional leveling |
