Brick houses are characterised by beauty, stability, and class. However, a brick wall, however strong it may be, may develop weaknesses over time, particularly when subjected to adverse weather conditions. The brick joint mortar is important in ensuring that your walls are robust, sealed, and weatherproof. Once this mortar begins to crack or crumble, your house becomes susceptible to moisture, frost, and damp-related destruction. That’s where repointing brickwork in London comes in.
Repointing is a process that involves scraping out broken mortar and then filling the void with a new mix to restore the wall’s strength and resistance. Here’s why repointing is so important in keeping the elements out of your house.
What Is Repointing and Why Is It Necessary?
Repointing Renewal of the outer face of mortar joints in masonry is called repointing. Mortar erodes over time due to exposure to weather elements, creating spaces between bricks. Such openings allow water to enter, particularly when it is raining or when there is frost. Otherwise, the moisture may seep into walls, causing internal dampness, mould, and structural weakening.
Contrary to bricks, mortar is meant to be the weaker one. This is because it can be replaced easily, unlike bricks. Homeowners can prolong the life of their walls without completely rebuilding them by just repointing the mortar.
How Weather Affects Brickwork?
The masonry can be difficult to withstand the weather in the UK with its combination of rain, frost, and wind. The largest threat is water. When it comes into contact with a wall, it releases pressure on the bricks and mortar as it expands when subjected to freezing conditions. This causes cracking, bubbling, and crumbling.
Repointing helps prevent water penetration by sealing the wall surface. It prevents the penetration of moisture and its internal transmission. This prevents damage to internal walls, insulation, and finishes, and also enhances thermal performance.
Signs Your Brickwork Needs Repointing
Knowing when to act is important. Here are common signs your home may need repointing:
- Gaps or cracks in mortar joints
- Loose or crumbling mortar
- Damp patches on interior walls
- White powdery stains (efflorescence)

If you notice any of these signs, it’s best to consult a professional before damage worsens.
