Tuckpointing is necessary when your home experiences cracked, deboned and disintegrated mortar joints. These cracked and deteriorated mortar joints are the number one reason for water penetration into your home. The intrusion of water may appear on your ceiling or walls and in some cases biological growth such as moss, mold or mildew will form requiring proper remediation.
How long mortar joints will last depends on the amount of exposure it has to Chicago’s extreme weather conditions and the mortar materials used.
Spalling or flaking brick is a condition caused by too much moisture. In the winter, this moisture freezes creating expansion thus forcing the bricks to split and break apart.
Damaged bricks should be removed and replaced and the immediate area properly tuckpointed to stop further erosion to the masonry structure.
