What is a garage lintel?

A lintel is a horizontal beam across the top of your garage door frame. Lintels are made of brick, concrete, stone, or wood, depending on the home. They support the structural integrity of the garage door, and when compromised can lead to bowing, sagging, or cracked bricks above your garage door frame.

Why does my garage door header sag in the middle?

The cause of a sagging garage door frame is usually an undersized lintel. The lintel is simply not strong enough to hold up the weight of the bricks above, causing bowing in the middle at the weakest point. This also puts pressure on the brick veneer above, causing vertical or stairstep cracking that decreases safety, curb appeal, and home value.

But even garage lintels that are properly sized may fail over time due to corrosion. Old wood lintels may also become damaged from moisture or termites. If you're noticing sagging, bowing, or cracking above the garage door header of your home, the rest of your home could be at risk for structural damage as a result.

How do I know if my garage lintel is failing?

Common signs of lintel failure include sagging or bowing above your garage door frame, typically in the center. Cracks may also appear in the bricks above the garage door, near corners or in the center. These lintel cracks are usually enough to confirm a failing garage door lintel.

Do I need to fix the cracks above my garage door header?

Vertical cracks also appear above compromised garage door lintels. As the lintel sags, the brick veneer above it faces increased pressure, leading to cracks.

The short answer is yes. But simply filling in the cracks (tuckpointing) only addresses the symptoms. Not fixing the cause - the failing garage lintel - can lead to:

  • Total collapse of the bricks
  • Moisture damage
  • Pest infestation
  • Lintel Collapse: Without proper repair, a garage lintel will continue to bow and put the bricks above at risk of collapsing and falling.
  • Moisture damage: Garage lintel cracks also create easy access for moisture. If a steel beam is exposed to moisture, it can rust and require total lintel replacement. Moisture can also lead to further warping and sagging of the garage lintel.
  • Infestation: Like any vulnerable area of your roof or foundation, pests may access your home through lintel cracks, causing more damage. No matter which symptoms of garage lintel failure you're seeing, LintelLift can provide quick, safe lintel repair that lasts.
