How To Maintain Brick Surfaces

Bricks are one of the most popular building materials for a reason: they are low maintenance and resilient against the elements and can remain intact throughout your future life as a homeowner. However, things do happen. Cracks can occur in the joints, and mildew can cause damage to the surfaces. So the question is then, what steps do we take to maintain our bricks over time? How can we ensure our brick walls never crumble? There is a way, dear reader. Read onwards to find out how to maintain your brick surfaces.

How To Maintain Your Brick Surfaces

Moss, Mildew, and Mold

When your home struggles to receive sunlight and there is often damp vegetation around, it is common for moss, mildew, and mold to start growing on the surface of brick walls. Fear not, fellow homeowners, there are solutions to this problem. Simply wet the brick wall with water, then with a cup of bleach mixed with a litre of water, apply it to the wall with a scrub and brush.

Water Damage

Water damage on brick walls is caused by the weather by splashback or rising damp. What is splashback? Splashback is continuous rain falling against the bricks, causing the mortar to soak in the water, leading to cracks in the mortar. What is rising damp? When the ground’s water seeps up from the ground, it leaves behind a line on brick walls, referred to as tide lines. The moisture above the ground evaporates, but the bricks are damaged from the salt crystals that remain. Freezing and thawing in winter can occur, too, further damaging wet bricks on your property.

The only way to prevent ongoing damage is to call in professional brick pavers to replace the damaged water-soaked bricks with fresh mortar and bricks. Make an annual budget for this project, as it may occur as a regular issue to your house.


Repointing is the replacement of mortar after it has cracked. The cracked mortar is removed with care by professional brick pavers and is replaced with fresh mortar on the surface.

If you own a house that may be historical, then you may want to ensure that the fresh mortar is the same as the original. You’ll need to call in a contractor to take a sample. The contractor will crush the sample up and dissolve the sample in acid. The acid will remove the binding agents and leave behind the sand aggregate, assisting the contractor to identify which shade must be used in the fresh mortar.


Damage to brick is real, and the size of the maintenance project will depend on how fast you tackle the issues.
