Not every crack means your foundation is failing. Here's how to tell the difference before you panic about a hairline shrinkage crack, or ignore one that actually needs attention.
Burleson sits on Blackland Prairie and Eagle Ford clay, soils that swell when they absorb moisture and shrink hard during dry spells. That cycle repeats every year, and it doesn't push on a slab or pier-and-beam foundation evenly — one corner or section usually moves more than the rest. Concrete and masonry can't flex with that uneven movement, so they crack along their weakest point instead.
A few patterns tell you most of what you need to know before anyone even shows up with a level:
If it matches the cosmetic pattern, it's reasonable to monitor it and note whether it changes over the next few months. If it matches any of the structural patterns, the next step is a free elevation survey, not a repair quote — that's what actually tells you whether the crack needs sealing alone, or whether the section needs piering first so the crack doesn't just reopen. Straightforward structural cracks are usually handled with epoxy or polyurethane injection.
A diagonal crack running from the top corner of a door or window frame is one of the clearest signs of differential settlement, since that corner is where structural stress concentrates first. Worth having it measured during a free elevation survey rather than assuming it's cosmetic.
A DIY sealant can mask whether a crack is still actively moving or how deep it goes, and it can make a professional repair harder to bond to later. If the crack is structural, patching it does nothing about the settlement causing it.
A single crack injection typically runs $400–$800. Homes with multiple cracks, or cracks tied to a drainage issue, run $1,200–$1,800 for the full scope. See the full cost breakdown by repair method for how this compares to piering and other fixes.
