Some new cracking is expected if the structure was lifted, because finishes adapted to the settled position. Cracks that continue to widen months later mean the movement was not arrested, which is a warranty conversation.
More detail
Two very different situations produce the same complaint, so separating them is the first job. Expected. If the repair included lifting rather than only stabilizing, the structure moved, and drywall, tile, brick, and trim that had adjusted to the settled geometry get stressed by the correction. Cosmetic cracking in the weeks following a lift is normal and is why lifting is usually done in small increments. Whether cosmetic repair is included is a contract question that should have been settled before the work. Not expected. Cracks that appear months later, cracks that widen measurably over time, doors that go back out of square, or a floor that slopes again. That means load is still moving, and the likely causes are piers that did not reach competent bearing, insufficient pier count for the actual load, movement in an area outside the repaired zone, or an unaddressed cause such as a plumbing leak or a drainage condition that was never corrected. What to do. Document with dated photographs and width measurements at marked points, which is the evidence that distinguishes settled cracking from progressive cracking. Re-read the warranty for what it covers, what triggers it, and what notice it requires. Contact the contractor in writing, since warranty terms often specify written notice. If the original work was engineered, have the engineer evaluate rather than the contractor, because the question is whether the design performed. On warranty language generally: many in this trade are marketed as lifetime and transferable, and the value sits in the exclusions. Common ones exclude movement in areas not covered by the original scope, damage from new water intrusion, and cosmetic repair. Reading them before signing is the only leverage point, which is worth remembering on the next quote rather than this one.
