Winter is the most destructive season for masonry in Illinois. Snow, ice, and freezing temperatures attack brickwork from every angle. The main culprit is trapped moisture combined with repeated freezing.

Mortar is more porous than brick, which means it absorbs water easily. When mortar freezes, it expands and begins to break apart. Once mortar joints fail, bricks lose their support and can loosen or crack.

Ice dams and poor drainage make the problem worse. Water that does not drain properly sits against masonry walls and foundations. Over time, this leads to deep cracks, spalling bricks, and even interior water damage.

Salt used on sidewalks and driveways also contributes to masonry decay. Deicing salts penetrate brick surfaces and accelerate deterioration, especially near ground level.

Professional masonry contractors near me in Oak Park often recommend repointing before winter hits. Fresh mortar joints restore strength and help keep water out. Ignoring winter damage only guarantees bigger repairs in the future.
