Expert Chicago Lintel Replacement & Repair

The Hidden Cause

Why Lintels Fail: The Danger of “Rust Jacking”

The steel angle above your window or door is responsible for carrying the massive weight of the masonry above it. When that steel is exposed to moisture, it corrodes and begins to expand—a destructive process known as rust jacking. This expansion exerts incredible pressure, forcing the surrounding brickwork apart.

Stair-Step Cracks

Cracks that follow mortar joints diagonally away from the top corners of your window.

Horizontal Cracking

A crack running straight across the mortar joint right above the opening.

Rust Stains

Orange or brown streaks bleeding through the brick or mortar.

Deflection

Bricks above the window that appear to sag, bow, or protrude outward.

The Warning

Caulking over these cracks makes the problem worse by trapping more moisture inside. The only safe, long-term solution is replacing the compromised steel.
