Maintaining the integrity of your home's structure and protecting it from water and damp is crucial, which is why mortar plays a critical role in holding bricks, stones, and blocks together. Over time, mortar can weaken and wear down, putting your home at risk. Repointing involves removing and replacing this essential material, which helps to fix any damage and wear and tear on your property.
It also improves the appearance of your home and enhances the durability of your walls, especially in older homes. With the use of new mortar, you can reduce damp and ensure that your walls can withstand all types of weather conditions. Over time, extreme weather can cause erosion of the mortar in homes. This means that repointing will eventually be required, though a high-quality job could last more than 50 years.
Some signs it's time to repoint your walls include mortar that is soft and crumbly, wet bricks, damaged brickwork, and holes in the mortar. If you notice a white powdery coating on your bricks, this is called "efflorescence." It's often caused by dampness, so it's important to identify the source of the problem before repointing. If poor-quality mortar isn't the cause of the damp, repointing could actually make the issue worse by trapping the damp. If in doubt, talk to a professional bricklayer.
