Repointing Your Walls

Repointing is the process of renewing the pointing, which is the external part of mortar joints in masonry construction.

Over time, weathering and decay cause voids in the joints between masonry units, usually in bricks, allowing the undesirable entrance of water. this process can breathe new life into the wall, making it not only look much better, but make it more weather-resistant, stable and therefore safe.

A brick wall can be a thing of beauty, whether on a house, an industrial building or a garden divider. Over time the mortars used can break down, making the wall look unsightly. Not only that, it can make it less stable and vulnerable to collapse.

It involves ‘raking’ any old mortar from the joints between the bricks, cleaning out any dust and then refilling the joints with new mortar. It’s a slow process, but the results can be stunning! What was an old, crumbling wall can become an attractive feature in itself. It can completely rejuvenate a house front or make your garden wall something to look at instead of something to try to hide.

An older wall in need of repointing

Repointing a wall, if done incorrectly, can actually cause damage to the wall. So it’s always best to involve a professional, who will know the best techniques and materials to use.

It’s possible to keep the original character of the wall, but give it a new lease of life. This can be done by using different colours and textures in the repointing.

Why Is Repointing Important

When it rains and the water hits a building, some of it can be absorbed into the stone, brick or the mortar. Also, some is drawn into the wall through small cracks between the masonry units and the mortar itself. To prevent this problem from occurring, the moisture needs to escape back to the atmosphere when the rain has stopped.

The best way to do this is to allow it to travel through permeable mortar joints. But if the joints cannot release the moisture, all of it is concentrated on the bricks or stones. This can drastically increase the chance of frost damage or other forms of damage.

The process of repointing not only affects the durability of the masonry, but how it looks too. Incorrectly done, repointing can damage your stone or brickwork and, sometimes, cannot be fixed.
