Leander homeowner guide · Updated July 2026
Leander foundations are young post-tension slabs on freshly graded lots — which changes the repair conversation, the warranty path, and what early cracks actually mean.
Leander's foundation story is written before move-in: post-tension slabs (the volume-building standard here) poured on lots graded months earlier, with perimeter soil still settling and landscapes not yet managing water. That produces a predictable year-one-through-five pattern — hairline slab shrinkage cracks, drywall seams opening at corners, doors adjusting seasonally — most of it cosmetic, some of it drainage-driven, and a small fraction genuinely structural. Sorting which is which, and knowing when the builder's ten-year structural warranty is the right door to knock on, is the whole game.
New slabs shrink as concrete cures; hairline surface cracks in a garage floor are normal aging, not distress. New perimeter soil settles; slight separation at patios and walks is common. The signals that rise above normal: stair-step cracks in brick, doors and windows racking and staying racked, drywall cracks that reopen after repair and widen seasonally, slab cracks with vertical offset. Pattern beats any single symptom — distress clustered on one side, especially a side with drainage problems or a gutterless roofline dumping there, tells the real story.
Texas builders typically carry ten-year structural warranties on new homes, administered through warranty companies with defined claim standards — usually requiring measurable movement beyond stated tolerances, documented by engineering. If your home is inside that window and showing real structural signals: document with dated photos, get the elevation survey, and open the warranty claim before hiring repair contractors, because out-of-pocket repairs can complicate coverage. An independent structural engineer's report ($300–$600) speaks the warranty administrator's language and is the best money in the process. Past the window, the standard playbook applies.
Post-tension slabs contain steel tendons under enormous stress — which changes everything about repair. Piering a PT slab is done regularly and safely by companies that know them, but cutting or drilling one is specialist work, and any contractor's plan should identify tendon locations before penetrating anything. Ask directly: how many post-tension repairs has the company done, how do they locate tendons, and does the scope note PT-specific handling? Hesitant answers end interviews. The county-wide companies serving Leander handle PT stock routinely; their scopes should show it.
Most early Leander "foundation problems" are water problems on immature lots: gutterless rooflines (common on volume builds — add them), settling backfill creating negative slope at the perimeter (regrade it), and irrigation soaking one side daily (rebalance it). Even moisture is the goal — including perimeter soaking in drought, which matters for young slabs exactly as for old ones. Hundreds spent here routinely prevents the thousands the pier quote describes; any company that skips the drainage evaluation before quoting steel is answering a different question than yours.
| Common job | Low | Typical | High |
|---|---|---|---|
| Evaluation w/ elevation survey | Free | $150 | $400 |
| Independent structural engineer report | $300 | $450 | $600 |
| Gutters + discharge routing (typical home) | $900 | $1,600 | $2,800 |
| Drainage correction (grading/drains) | $500 | $1,500 | $4,000 |
| Pier project on PT slab (when warranted) | $4,500 | $8,000 | $13,000 |
Usually no: curing concrete, settling backfill, and seasonal clay movement produce cosmetic cracking in young homes routinely. Photograph and date them, fix the drainage feeding any pattern, and escalate only on structural signals — racking openings, stair-step brick, offset slab cracks.
Document movement with dated photos and an elevation survey, review your warranty booklet's claim standards, and file through its process — ideally with an independent engineer's report attached. Do this before paying for repairs; out-of-pocket work can muddy coverage.
Yes — PT slabs carry stressed steel tendons, so any penetration requires locating them first, and repair contractors need demonstrated PT experience. Piering PT slabs is routine for companies that know them; verify yours does before signing.
