Masonry contractors near me Chicago

 

Freeze and thaw cycles are one of the most destructive weather patterns for brick homes. They are also the most underestimated. Many homeowners notice damage but do not connect it directly to temperature changes. Masonry contractors near me Chicago see this pattern constantly.

The process is simple but aggressive. Water enters small cracks in mortar joints. When temperatures drop, that water freezes and expands. Expansion creates pressure from within, forcing the mortar to crack further. When temperatures rise again, the ice melts, leaving more space for water to enter.

This cycle repeats dozens of times during winter. Each repetition weakens the mortar more. Eventually, it begins to crumble or fall out entirely. At this point, tuckpointing becomes necessary to restore stability.

Bricks are not immune either. When moisture is trapped behind damaged mortar, it can cause spalling. This means the surface of the brick starts to chip or flake off. Many assume this is a brick issue, but the root cause is almost always failed mortar joints.

Chimneys and upper walls are hit the hardest. These areas are fully exposed and absorb the most moisture. Masonry contractors often recommend more frequent tuckpointing for these sections because they deteriorate faster.

Preventing freeze and thaw damage starts with maintenance. Sealing small cracks early and keeping mortar joints intact reduces water penetration. Once the cycle begins, damage accelerates quickly.

Ignoring it does not save money. It guarantees larger repairs later.
