Brickwork Maintenance: Keeping Your Property Solid

Brick is one of the most durable building materials, but it is not indestructible. Over decades, exposure to the British weather can cause mortar to degrade and bricks to "spall," leading to damp and structural issues.

1. Spotting the Warning Signs

Early detection is key to avoiding expensive repairs. Walk around your property and look for:

• Cracked or Missing Mortar: If you can see gaps between bricks, water can penetrate the wall.
• Spalling Bricks: This is when the face of the brick starts to flake off, usually caused by the freeze-thaw cycle.
• Efflorescence: White, powdery salt deposits on the surface, which indicate moisture moving through the masonry.
• Vegetation Growth: Moss or ivy may look attractive, but roots can expand existing cracks and trap moisture.

2. The Importance of Repointing

The mortar joints are the "sacrificial" part of your wall. They are designed to be softer than the bricks so that moisture evaporates through them rather than the brick itself. When mortar wears away, it must be replaced - a process called repointing.

Professional repointing not only makes your house look new but also provides a vital waterproof seal that protects the structural integrity of the entire building.

3. Choosing the Right Mortar

This is where many DIY attempts go wrong. Using modern cement mortar on older, lime-based brickwork can trap moisture and cause the bricks to crumble. It is essential to match the mortar strength and composition to the original materials used in your property.

Summary: A Solid Foundation

By spending a small amount on maintenance and repointing today, you can avoid spending thousands on structural repairs and damp proofing tomorrow. Your home’s exterior is its first line of defense - make sure it’s a strong one.
