Let’s start by understanding what weather pointing is and why it’s vital for London properties.

1. What Is Chimney Repointing and Why Is It Needed?
2. Chimney repointing involves removing damaged, cracked, or eroded mortar from between bricks and replacing it with fresh mortar.
3. This process is crucial for keeping the structure weatherproof, secure, and visually appealing.

What Is Weather Pointing?

Weather pointing is a specific style of pointing that slopes outward to drain water away from the mortar joints.

It’s especially relevant in London, where rain, wind, and frost can wreak havoc on masonry over time.

Signs Your Chimney Needs Repointing

Crumbling mortar between bricks

Visible cracks or loose bricks

Damp patches or staining inside your loft

Brick movement or leaning

Water leaks from the chimney stack

2. Why Chimney Repointing Matters in London’s Climate

London experiences a high number of wet days annually, and its frequent temperature swings cause thermal expansion and contraction of building materials.

How Weather Affects Chimneys

Rain seeps into old mortar, causing erosion and internal damp

Frost freezes trapped moisture, expanding and cracking bricks

Wind drives water into exposed joints, weakening structural integrity

Without weather pointing, your chimney becomes vulnerable to costly damage.
