Garage lintel repair fixes the beam that spans the top of your garage door opening after it cracks, sags, or shifts. On homes in Round Rock, this usually shows up as stair-step cracks above the door or a gap along the frame. Most repairs run $1,500–$6,500, depending on the cause and what the foundation underneath is doing.

The garage door opening is the widest span in most houses, and it carries a lot of weight with very little wall on either side to help. So when the foundation moves, the corner by the garage is often the first place you see it. That is why we look at the lintel and the slab together, not just the crack itself.
Signs You Need Garage Lintel Repair
You do not need to be a builder to spot most of these. Walk out to the garage and look above the door.
- A stair-step or diagonal crack starting at the top corner of the garage door opening
- The lintel or the brick above the door looks like it is sagging or bowing down in the middle
- A gap opening up between the garage door frame and the wall
- The garage door sticks, drags, or no longer seals evenly along the bottom
- Cracks in the brick or stucco above the door that keep coming back after you patch them
- Daylight showing through where the frame meets the wall
One hairline crack is common and usually not urgent. A crack that is growing, a visible sag, or a door that has stopped working right is worth having us take a look.
How Garage Lintel Repair Works
Here is what you will actually see on site.
- We look at what is happening. We check the lintel, the brick above it, the slab, and the elevations around the garage. A crack over the door is often a symptom of soil movement under that corner, so we figure out the cause before we quote a fix.
- We explain the repair options in plain English. Sometimes it is the lintel itself. Sometimes the lintel is fine and the slab under the garage has settled and needs to be stabilized first.
- If the foundation moved, we stabilize it. For a settled garage corner, that usually means piers driven to refusal to support the affected area before any cosmetic work.
- We repair or replace the lintel. Depending on severity, that can mean adding a steel angle or beam for support, or replacing a deteriorated lintel and rebuilding the masonry above it.
- We address water and drainage. Poor drainage at the garage corner speeds up soil movement, so we talk through grading, gutters, and downspouts to protect the repair.
Garage Lintel Repair Cost
Below are typical Central Texas ranges. Your number depends on why the lintel failed and what the slab underneath is doing.
| Repair type | Typical range | What drives the price |
|---|---|---|
| Steel angle / lintel reinforcement | $1,500–$3,500 | Span width, single vs. double door, masonry type |
| Full lintel replacement + masonry rebuild | $3,000–$6,000 | Amount of brick/stucco to remove and rebuild, access |
| Piers to stabilize a settled garage corner | $2,500–$6,500+ | Number of piers, depth to stable soil, access around the drive |
| Cosmetic crack repair only (no movement) | $400–$1,200 | Length of crack, finish type |
Variables that move the price:
- Whether the foundation moved, or just the lintel
- Single-car vs. double-car opening (the wider span costs more)
- Number of piers and how deep they must be driven to reach stable soil
- Access — a tight side yard or finished driveway makes the work harder
- Brick, stone, or stucco finish above the door
- Severity of the crack and how much masonry has to be rebuilt
We give free estimates on every job. You will get a written repair plan, not a vague “it depends.”
Lintel Repair vs. Foundation Piers
These are not the same job, and it is worth being honest about which one you need.
If the lintel cracked from rust, age, or an undersized beam and the slab is still holding its elevation, lintel repair alone is the right call. Adding piers you do not need is a waste of your money.
If the crack over the door is coming from a garage corner that has settled into the Blackland Prairie clay, lintel repair alone will not hold. Patch the crack and it comes back, because the ground under that corner is still moving. In that case you stabilize the foundation first with piers, then repair the lintel and masonry. We will tell you which situation you are in based on the elevations, not a guess.

Frequently Asked Questions
Is a crack over my garage door a serious problem?
Not always. A single hairline crack is common in Central Texas homes. What matters is whether it is growing, whether the lintel is sagging, and whether the door still works. Those signs point to movement worth inspecting.
Why does the garage corner crack before the rest of the house?
The garage door opening is the widest, weakest span in the wall, with little to brace it on either side. When the soil under that corner moves, the lintel above the door shows it first.
Can you just patch the crack?
If the lintel and slab are stable, yes — a cosmetic repair is fine. If the corner has settled, patching alone will not last. The crack returns because the ground is still moving underneath.
Will my garage door work normally after the repair?
Usually, yes. Once the corner is stabilized and the lintel is supported, a door that was sticking or dragging typically opens and closes evenly again. Badly damaged doors may need a garage-door tech separately.
How long does garage lintel repair take?
Most repairs take one to three days. Stabilizing a settled corner with piers and rebuilding masonry takes longer than a straightforward lintel reinforcement.
Does drought and rain in Round Rock cause this?
Often, yes. Taylor Black Clay swells when wet and shrinks when dry. A dry summer followed by a wet fall moves the soil under the garage, and a new crack over the door in October is a classic sign of that seasonal swing.
Do I need an engineer?
Sometimes. When the repair involves the foundation, an independent engineer can review the elevations and repair plan and provide final documentation. We will tell you if your job needs one.
