Most lintel repairs are just temporary patches.
Garage door lintels sag over time because the 5/16" steel angle iron rotates forward under the weight of the masonry above. Cracks appear, mortar joints snap, and the brick starts to dive.
Traditional contractors fill the cracks and walk away. The cracks come back — because nobody addressed the rotation. LintelLOCK™ is the only system engineered to correct the rotation, anchor the steel, and lock it permanently.
- — Mortar-only fixes don't address structural rotation
- — I-beam "solutions" are expensive overkill
- — Cosmetic patches crack again within months
- — Ignoring it leads to falling brickwork and safety hazards
How LintelLOCK™ works
LintelLOCK™ is a structural method — not a cosmetic patch. It is built to solve sagging masonry above garage openings by correcting and securing the underlying support.
Confirm the lintel is the root cause (not just mortar shrinkage). Identify rust, movement, and load paths.
The system is designed to draw the failing steel angle back into place before it gets worse.
Hardware + method create long-term support so the repair is not a short-term patch.
Installers complete the masonry finish so the opening looks right again.
LintelLOCK™ is provided through registered, certified contractors. Homeowners — use the contact form to get connected to an installer in the Dallas–Fort Worth area.
