Joint repointing, also known as tuckpointing, is the process of renewing or repairing the external part of mortar joints in masonry construction. Over time, mortar joints can deteriorate due to weathering, age, or other factors. Joint repointing involves removing the old, damaged mortar and replacing it with fresh mortar, enhancing the structural integrity and appearance of the brickwork. This meticulous process requires skill to match the original style and color, ensuring a seamless and durable result.
