Foundations in Castroville
Castroville is the Alsatian town twenty miles west on US 90 in Medina County, founded in 1844: historic stone and fachwerk houses on rubble footings, 1970s to 2000s slabs on alluvial and clay soils along the Medina River, and new subdivisions on the edges. It runs its own permit office and historic review.

Working the area
Regular work around Medina River, Castroville Regional Park, Landmark Inn State Historic Site and US 90, and the streets between.
Castroville is masonry history and new clay on the same river. The town was founded in 1844 by Alsatian settlers, and the historic core along the streets near the Landmark Inn still holds stone and fachwerk houses from the 1840s to 1880s on rubble footings, which settle and crack at the corners as the alluvial soil along the Medina River moves with the water table and the mortar between the stones gives up after a century and a half. That work is masonry, helical piers where vibration next to a stone wall matters, and the city's historic district review. The 1970s to 2000s homes around the core are thin slabs on alluvial and clay soils that move with the river, wetter on the river side and drier toward US 90, with the usual cracked corners and heaved interiors over old drains.
The new subdivisions on the edges of town went in on scraped clay and fill with builder drainage that ends at the corner, and the post-tension slabs there tilt with the seasons like the northeast suburbs. The Medina River floods, and lots on the river side stay wet. Castroville runs its own permit office. It is a longer drive than most of our coverage, and the evaluation window says so, but the same crew that presses pilings on the clay handles the stone in the historic core with an engineer's plan.

Reshimming, rotted sill and beam replacement, new piers and crawl space moisture control for pre-1960 homes.
Pressed concrete pilings, steel piers or drilled piers under a settled slab, with a hydrostatic test before and after the lift.
Elevation survey, crack mapping and an honest read on whether the house needs piers, drainage or just watching.
Lifting a settled house back toward level in stages, doors closing again, and a written elevation record.
Which cracks are cosmetic, which are structural, and epoxy or polyurethane injection once the cause is fixed.
Hydrostatic testing, tunneling under the slab and drain repair when wet clay is heaving one side of the house.
Before we arrive
Foundation movement on clay is a story told over seasons. The more of it you can show us, the more honest the answer.
Every crack inside and out with a coin for scale, plus the month. Seasonal movement on clay shows up as cracks that open in August and close in November.
Where do the downspouts dump, where does water pool after a storm, which side has the big live oak, and is there a wet spot that never dries.
Previous repair warranties, engineer's letters, the seller's disclosure and any plumbing test. They change the plan and sometimes cover the work.
Neighborhood, foundation type if you know it, what the house is doing and your timing. You get an evaluation window and what to watch for meanwhile.

Castroville questions
Straight answers on scheduling, local failure patterns, cost per pier and insurance.
All questionsEvaluations in Castroville are usually scheduled within a few days, and typical travel is around 30 minutes from wherever the crew is working. Active movement after a plumbing leak or a sudden drop goes to the front of the queue. You get a real window on the phone rather than a promise. While you wait, photograph the cracks with a coin for scale and note where water pools around the slab after rain.
The pattern we see most in Castroville is historic stone and fachwerk houses from the 1840s to 1880s on rubble footings settling and cracking at the corners, followed by 1970s to 2000s slabs on alluvial and clay soils along the Medina River moving with the water table. Castroville is the Alsatian town twenty miles west on US 90 in Medina County, founded in 1844: historic stone and fachwerk houses on rubble footings, 1970s to 2000s slabs on alluvial and clay soils along the Medina River, and new subdivisions on the edges. It runs its own permit office and historic review. Drought summers and wet springs move the soil everywhere in the metro, so seasonal cracks and sticking doors show up in every neighborhood.
Typical San Antonio ranges apply in Castroville: pressed concrete pilings run $350 to $600 per pier, steel piers $1,000 to $1,800, and most homes need 8 to 12 piers, so a typical slab repair lands between $4,500 and $14,000. Pier and beam leveling runs $1,500 to $5,000 before any rotted wood is replaced. Drainage correction often costs less than piers and is sometimes the whole fix. Every number is in a written proposal after the evaluation.
Usually not for soil movement. Texas homeowners policies generally exclude damage from settling, shrinking and expansion of the soil. If a plumbing leak under the slab caused the movement, part of the repair may be covered depending on the policy and any foundation or seepage endorsement, often with a cap. A hydrostatic plumbing test, dated photos and an engineer's report are what the adjuster asks for.
