Repointing

Repointing is the process of repairing or replacing the mortar joints between bricks, stones, or other masonry units in a wall or structure. Mortar is a mixture of cement, sand, and water that is used to hold masonry units together and provide a weather-resistant seal. Over time, mortar can become damaged or degraded due to weathering, wear, or settlement, leading to loose or crumbling joints. Repointing involves removing the damaged mortar and replacing it with new mortar, in order to restore the structural integrity and weather resistance of the wall or structure.

Repointing is often necessary in older buildings, as the mortar used in the original construction may not meet modern standards for strength and durability. It can also be necessary in newer buildings if the mortar has become damaged due to poor construction practices or other factors. Repointing requires specialized skills and equipment, and is typically carried out by professional masonry contractors. In addition to improving the appearance and structural integrity of a building, repointing can also help to improve energy efficiency and reduce the risk of water infiltration.
