Brickwork is a durable and long-lasting building material, but over time, the mortar that holds bricks together can deteriorate due to weathering, moisture, and general wear and tear. Repointing is the process of renewing the mortar joints to restore structural integrity and prevent further damage. If you’re wondering whether your brickwork needs repointing, here are the key signs to look out for.
1. Crumbling or Missing Mortar
One of the most obvious signs that your brickwork needs repointing is crumbling, cracked, or missing mortar between the bricks. As mortar erodes, it leaves gaps that can weaken the structure and allow water to seep in, leading to further damage.
2. Water Ingress and Damp Issues
If you notice damp patches inside your home or water seeping through your walls, deteriorated mortar may be the culprit. Damaged mortar allows moisture to penetrate, which can cause mould, mildew, and structural issues if left untreated.
3. Loose or Unstable Bricks
Bricks should always feel solid and secure. If you notice that some bricks feel loose or move slightly when touched, the mortar holding them in place may have weakened, requiring immediate repointing to prevent further displacement.
4. Visible Gaps in the Mortar Joints
Over time, weathering can cause mortar joints to erode, leaving visible gaps between bricks. These gaps not only affect the appearance of your property but also make it more vulnerable to water damage and structural instability.
5. White Powdery Residue (Efflorescence)
If you see a white, chalky substance on your bricks, known as efflorescence, it could indicate excessive moisture absorption. This can be a sign that your mortar is no longer providing adequate protection, and repointing may be necessary.
6. Increased Energy Bills
Deteriorating mortar can allow draughts and moisture to enter your home, reducing insulation efficiency. If you’ve noticed a sudden increase in heating costs, repointing your brickwork can help improve energy efficiency by sealing gaps and preventing heat loss.
7. Damage After Harsh Weather
Extreme weather conditions, such as heavy rain, frost, and strong winds, can accelerate mortar deterioration. If you’ve recently experienced harsh weather, inspect your brickwork for signs of damage and consider repointing if necessary.
