Stair-step cracks, drywall cracks, and gaps
Brick veneer is rigid, so it shows foundation movement quickly. In Tulsa, the classic pattern is a stair-step crack running diagonally through the mortar joints, often below a window or at a corner.
What the pattern tells you
- Stair-step cracks in brick usually indicate differential settlement, one part of the foundation dropping relative to another.
- Diagonal drywall cracks from the corners of doors and windows often mirror the same movement inside.
- Gaps between trim and ceiling or floor can point to heave or sag.
- Separation at brick frieze boards or window frames shows rotation of a wall.
When it's likely seasonal
Hairline cracks that open slightly in August drought and close in spring are typical of clay soil. Consistent watering and good drainage can limit them.
When to call
Call for an evaluation if cracks are wider than about 1/4 inch, keep growing, reopen after patching, or come with sticking doors, sloping floors, or a chimney pulling away.

Frequently Asked Questions
Should I tuckpoint brick cracks now?
Wait until movement is diagnosed and stabilized. Patching first just hides evidence and the crack will often reopen.
Do new homes get brick cracks?
Yes. Newer subdivisions on fill or freshly disturbed clay can show cracks in the first few years. Check whether a builder warranty applies.
