Sagging Lintel Above Garage Door
A sagging garage lintel poses risks to the garage's structural safety and can stem from aging, poor construction, or settlement nearby.
Locally owned & operatedSagging Lintel Above Garage Door is one of the clearest signs Central Texas homeowners notice when a foundation is on the move. In Central Texas, the cause is usually one of two things: expansive Blackland clay swelling and shrinking under the home with every wet-dry cycle, or the moisture and drainage conditions that come with it. The specific pattern and location of what you're seeing is what tells us which one it is.
Watch for these signs it's more than cosmetic
A visible dip or curve in the header above the garage door
Often easiest to see by sighting along the top of the opening from outside.
Cracking in the wall or brick directly above the opening
Cracking above the lintel suggests it's carrying more stress than it can handle.
The garage door beginning to bind or stick as the opening shifts
A functional symptom that often shows up alongside the visual signs.
What causes this problem?
Not every instance is foundation-related, but in Central Texas, it usually is. Here's what we rule in or out on inspection.
Aging or undersized original lintel
Some lintels weren't sized to carry the load above a wide garage opening long term.
Nearby foundation settlement
Settlement near the garage corner can add stress to a lintel that was otherwise adequate.
Water intrusion and corrosion
A steel lintel that's rusted from water exposure can lose strength and begin to sag.

How QFR addresses this
Why Central Texas foundations move
Austin's expansive Blackland clay shrinks in dry summers and swells after rain, cycling in volume with every wet-dry season. Homes built directly on this clay across Travis, Williamson, and Hays counties face ongoing movement pressure, and that movement shows up in different places depending on the home. We diagnose the pattern before we recommend anything.
"A garage lintel carries real weight over a wide opening, when it starts to sag, it's worth treating as a structural question, not a cosmetic one."
The difference is in the diagnosis
Get several quotes and you'll see a wide range of prices. The gap isn't luck, it's whether the contractor finds the actual cause and stands behind the work.
