When people think about brickwork, they often focus on the bricks themselves. However, the mortar between those bricks plays an equally important role in protecting a building from the elements and maintaining its structural integrity.
Over time, mortar naturally deteriorates due to exposure to weather, moisture, and movement within the building. Left untreated, failing mortar can allow water to penetrate walls, leading to damp problems, frost damage, heat loss, and, in some cases, structural issues that become far more costly to repair.
At Domsalla Building Services Ltd, we regularly help homeowners and commercial property owners across Sussex identify and resolve masonry issues before they develop into major problems.
Mortar is designed to weather over time, but certain conditions can accelerate its decline.
Common causes include:
We've frequently been called to properties where previous repointing work has been completed purely for cosmetic reasons, without properly removing the failed mortar beneath. While the wall may initially look improved, these shortcuts often lead to premature failure and further expense down the line.
Many property owners are unaware their mortar is failing until visible damage begins to appear.
Some common warning signs include:
If left untreated, these issues can allow significant water ingress, potentially causing damage to internal finishes and even affecting the stability of the structure itself.
Repointing is often viewed as a cosmetic improvement, but its primary purpose is protection.
Professional repointing can:
In many cases, addressing deteriorating mortar early can prevent the need for extensive brick replacement or structural repairs later, making it a highly cost-effective investment.
Successful repointing depends on far more than simply applying new mortar.
Proper preparation is essential. Existing mortar must be carefully removed to the correct depth before replacement mortar is installed. If this stage is rushed, the new pointing may fail within only a few years.
Equally important is selecting the correct mortar mix. Older properties, period buildings, and modern constructions often require different specifications. Using an unsuitable mortar can trap moisture, damage surrounding brickwork, and create an unsympathetic appearance.
This is why experience, knowledge, and attention to detail are so important when choosing a contractor.
Where cracking has occurred as a result of structural movement, repointing alone may not always be sufficient.
Domsalla Building Services Ltd also carries out Helifix resin repair and reinforcement systems, which allow damaged masonry to be strengthened and stabilised without the need for extensive rebuilding.
By combining Helifix repairs with specialist repointing techniques, we can often provide a comprehensive solution that restores both the appearance and structural performance of the wall.
