Mortar is porous, allowing it to absorb water. Over time and with the addition of freezing temperatures, water can expand in the mortar until the joints become cracked, often with chunks of mortar falling out completely. Our technicians can tuckpoint the damaged mortar, grinding and brushing out the joint, cleaning it, and refilling the area with new mortar. If damage has occurred in a larger section of the chimney, the entire section would be rebuilt.
