Foundation Crack Repair in Shreveport, LA: Slab, Brick, and Structural Cracks
Almost every Shreveport homeowner eventually sees a crack somewhere on their foundation, slab floor, or exterior brick, and the hardest part is knowing whether it is a cosmetic side effect of normal clay movement or an early sign of a structural problem. Because the region's expansive clay swells and shrinks every year, some cracking is close to inevitable, but the pattern, width, and location of a crack tell you a lot about whether it needs monitoring, simple sealing, or a full structural evaluation. This guide breaks down the most common crack types seen on Shreveport homes and what each one usually means.

Reading slab cracks
Thin, hairline cracks running in a fairly straight line across a garage or interior slab, especially near control joints, are common in Shreveport and are usually shrinkage cracks from the original concrete curing or minor seasonal movement, not structural failure.
Diagonal cracks that widen noticeably at one end, cracks wider than about 1/4 inch, or cracks accompanied by a visibly uneven floor (a ball rolling on its own, doors that won't latch) point toward differential settlement from the clay soil beneath and usually warrant a professional elevation reading.
Reading brick veneer and mortar cracks
Stair-step cracks in mortar joints on brick veneer are extremely common in Shreveport, especially on homes over 20 years old, and often reflect the veneer settling slightly independent of the wood-framed structure behind it; these can often be tuckpointed and monitored.
A stair-step crack wider than 1/4 inch, or one that runs continuously from the foundation up several courses of brick and is paired with a visible gap between the brick and window or door trim, suggests more significant differential movement and should prompt a full foundation inspection, not just mortar repair.
Cracks that mean call someone today
Horizontal cracks in a foundation wall, cracks where you can see daylight or feel air movement through the wall, and sudden new cracks that appear within days rather than developing gradually over months are all signs that warrant an immediate professional evaluation rather than a wait-and-watch approach.
Doors and windows that suddenly stick or won't latch, especially multiple doors on the same side of the house, paired with new cracking, often indicate active structural movement, and getting an elevation survey quickly can help determine whether piering is needed before the movement worsens.
Repair options by crack type
Hairline slab cracks are typically sealed with polyurethane or epoxy injection, running $400-$1,800 depending on length, which prevents water intrusion and further widening without requiring structural work.
Wider structural cracks, especially those with confirmed differential elevation, generally call for pier installation near the affected section rather than crack sealing alone, since sealing a crack without correcting the underlying settlement is a cosmetic fix that will likely fail again.
Documenting and monitoring cracks over Shreveport's seasons
Because clay movement is seasonal, it helps to photograph cracks with a ruler or coin for scale and note the date, then recheck after Shreveport's wet spring and dry summer to see if the crack width changes; stable width across a full wet-dry cycle is a good sign, while continued widening is not.
Simple crack monitors, small plastic gauges glued across a crack, cost only a few dollars and give a homeowner an objective way to track movement over a season before deciding whether to call a structural contractor.
Typical cost ranges
| Hairline slab crack sealing | $400 - $900 |
| Wider slab crack, polyurethane/epoxy injection | $900 - $1,800 |
| Mortar tuckpointing (per section) | $350 - $900 |
| Stair-step brick crack repair with flashing/relief | $700 - $1,500 |
| Structural crack repair with pier support | $1,200 - $2,300 per pier |
| Crack monitor gauges (DIY monitoring) | $5 - $30 |

Common questions
Is a diagonal crack always a sign of a structural problem in Shreveport?
Not always, but diagonal cracks over doors and windows that keep widening, especially paired with sticking doors, are more likely to reflect structural movement than straight, stable hairline cracks and deserve a professional look.
How wide does a foundation crack have to be before it's serious?
As a general guideline, cracks under about 1/8 inch that are stable are usually cosmetic, while cracks wider than 1/4 inch, especially if actively widening, warrant a structural evaluation, though the pattern and location matter as much as width alone.
Can I just fill a foundation crack myself?
For a small, stable hairline crack you can seal it yourself with a concrete crack filler as a stopgap, but if the crack is on a load-bearing wall, is wider than 1/4 inch, or is paired with other movement signs, have a professional assess it before sealing, since sealing can hide ongoing movement.
Why do brick homes in South Highlands get so many stair-step cracks?
Many South Highlands homes have brick veneer over wood framing on soil influenced by reactive upland clay; seasonal shrink-swell causes small differential movements between the veneer and framing that show up as stair-step mortar cracks, which are common but should still be monitored for width changes.
Should I get an engineer's opinion before paying for crack repair?
For any crack that is wider than 1/4 inch, is growing, or is paired with door/window problems, a $450-$900 independent structural engineer evaluation is worth the cost before committing to a repair contract, since it gives you an unbiased assessment separate from the company selling the repair.
