Water damage is a common issue for homes, particularly in areas with brick and stone walls. After some time, the mortar between the bricks may crack or crumble, allowing water to infiltrate the wall. This can cause the wall to become wet, leading to mould proliferation and even structural damage. Repointing in Sheffield is the process of removing old mortar and replacing it with fresh mortar, sealing gaps, and protecting the walls. Proper Repointing prevents water from entering, thereby strengthening the masonry and preserving the home’s value. Here, we will discuss the basic steps for repointing exterior walls, allowing you to prevent costly water damage and keep your home safe and dry.
What is Repointing, and Why is it Important?
Repointing involves removing weathered mortar from between bricks or stones and filling the joints with fresh mortar. As time goes by, wet and inclement weather weaken the mortar that has been subjected to natural weathering. When mortar fails, water invades the walls, causing damp patches inside your house or even leading to some old-fashioned brick damage. Repointing is an important maintenance procedure which avoids such problems by restoring the water-tight seal around your masonry. It also beautifies your walls, thereby enhancing your home’s energy efficiency by blocking drafts.
Steps to Repoint Exterior Walls
Let’s discuss the major steps that are included in repointing the exterior wall:
1. Inspect the Walls for Damage:
Scrutinise your walls for any cracks, instances of crumbling mortar, or gaps between brickwork. Give special attention to areas exposed to heavy rain or around downspouts, as these spots are more susceptible to possible water damage. Test the mortar by gently hitting it with a small hammer or scratching it with a chisel. If the mortar crumbles too easily, it is time to repoint.
2. Remove Old Mortar:
Chip away the old mortar carefully to a depth of about 20 mm (3/4 inch). Be cautious not to damage bricks or stones. Brush in all loose debris with a wire brush and then wet the joints with a water spray. This will help in ensuring a good bond with the fresh mortar.

4. Mix and Apply New Mortar:
Mix the mortar according to the package instructions. Use the trowel to fill the joints with mortar, pressing it firmly into the gaps. Smooth the surface to match the existing mortar finish. Avoid leaving gaps or air pockets.
5. Final Inspection and Cleanup:
After the damage dries, check the marked spots to be sure no cracks are still visible. Get rid of any unneeded mortar on the bricks by using a stiff brush. Maintaining your newly repainted walls is crucial to keep them safe and dry for years to come.
Repointing the exterior of your house keeps water damage out and lets your masonry live longer. If you complete these simple tasks, your home will remain dry, healthy, and presentable. Should you be unsure about completing the task yourself, employ a specialist to ensure the outcome is perfect.
