A rainy spring followed by a hot August can lift and then drop parts of a slab, and the uneven movement shows up as cracks and sticking doors. Tyler's hilly lots add another factor: runoff can wash soil out from the downhill side of a house.
National surveys for 2026 put the average foundation repair at about $5,000, with most projects between about $2,200 and $8,100. Projects with many piers can run well into five figures. Only an on-site inspection with elevation readings can give a real number, so ask any contractor for a written scope.
