Identifying Lintel Failure & Masonry Distress
Early detection is key to preventing costly structural damage. Our experts look for several red flags during a structural evaluation:
-
Step Cracking at Window Corners: Often the first sign of a failing lintel, diagonal “stair-step” cracks in the mortar joints indicate that the support beam is no longer carrying the load properly.
-
Rust Heaving & Deflection: As steel lintels corrode, they expand (oxidize), exerting upward pressure that cracks the surrounding brickwork and causes the beam to sag or “deflect.”
-
Water Infiltration: If you notice moisture or water leaking above windows and doors, it is often a sign of failed or non-existent masonry flashing installation.
Our Comprehensive Restoration Process
We don’t just replace the steel; we restore the entire opening to prevent future issues:
-
Precision Lintel Replacement: We remove the compromised steel and install new, heavy-duty primed or galvanized steel lintels that meet or exceed modern building codes.
-
Advanced Masonry Flashing Installation: To prevent future rust and interior leaks, we install high-performance end dams and masonry flashing. This system directs water out of the wall through specialized weep holes, keeping your substructure dry.
-
Structural Tuckpointing & Brick Replacement: After the new lintel is set, we meticulously replace any damaged bricks and perform precision tuckpointing to ensure a seamless, watertight finish.
