Many Tyler houses sit on a concrete slab. When the clay under one part of it dries and shrinks, or gets soaked and swells, the slab bends. The repair usually means supporting the low part on piers driven or poured down to firmer ground, then lifting it back toward level.
Signs of slab movement
- Stair-step cracks in brick, often near corners and windows.
- Drywall cracks above doors and windows.
- Doors that stick, swing on their own or won't latch.
- Floors that slope, or tile that cracks in a line.
- Gaps between the wall and the ceiling or trim.
Common repair approaches
- Piers (underpinning): Angi lists $1,000 to $3,000 per pier.
- Slabjacking (mudjacking): $500 to $1,300, for lifting a slab section where the soil itself hasn't shifted.
- Drainage fixes to stop the cause; see drainage correction.
Why evaluation comes first
Not every crack means the foundation failed. An evaluation measures elevations across the floor to see what moved and by how much. Angi lists a structural engineer's report at $300 to $1,000.
Permits
Ask City of Tyler Building Services ((903) 531-1151) whether your repair needs a permit; see permits and paperwork.
