Summer heat may seem harmless compared to winter, but it quietly damages masonry across Illinois. High temperatures cause bricks and mortar to expand. When temperatures drop at night, they contract. This daily cycle puts stress on masonry joints.
Over time, expansion and contraction lead to hairline cracks that allow water inside. Once moisture enters, future freeze-thaw cycles turn minor cracks into major failures.
Strong summer storms also play a role. Wind-driven rain can force water deep into brick walls, especially on older buildings without modern moisture barriers.
Sun exposure can weaken mortar faster than brick, causing joints to erode unevenly. When mortar deteriorates, bricks begin to shift and structural stability decreases.
Skilled masonry restoration near me Chicago contractors design repairs with thermal movement in mind. Using proper mortar mixtures and techniques ensures masonry can handle seasonal expansion without failing.
