Foundations in Harlandale
Harlandale is the south side between South Flores and the Mission Reach: 1940s to 1960s homes in Harlandale ISD on Blackland clay, split between the last pier and beam and the first thin slabs, near Mission San José. Old drains, mature trees and deferred maintenance.

Working the area
Regular work around Mission San José, Mission Reach of the San Antonio River, Harlandale ISD and South Flores Street, and the streets between.
Harlandale is where pier and beam ended and slabs began, on the same clay. The neighborhoods between South Flores Street and the Mission Reach of the river were built from the 1940s through the 1960s, and a single block can hold a 1946 pier and beam cottage next to a 1962 slab ranch. The pier and beam houses have the usual rotted sills, sunk concrete piers and floors that slope toward the corner that stayed wettest, with crawl spaces that are often tight and full of a previous owner's shims. The slabs are thin conventional pours on Blackland clay with cast iron drains underneath, and they crack at the corners under the trees and heave in the middle when a drain leaks, so the hydrostatic test comes first.
The lots near the river sit on a high water table, and a lot of yards drain toward the house. Harlandale is largely family-owned and multi-generational, with rentals mixed in, and the foundation problem has often been growing for twenty years before someone calls, usually when a door will no longer close or a buyer's inspector writes it up. Enclosed porches and garage conversions on their own footings pull away from the house. Pressed concrete pilings reach refusal at useful depths in this clay, and the typical job is perimeter pilings, interior piers over a repaired drain, or reshimming and new piers under the pier and beam houses, all inside San Antonio's permit office.

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.

Harlandale questions
Straight answers on scheduling, local failure patterns, cost per pier and insurance.
All questionsEvaluations in Harlandale 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 Harlandale is 1940s to 1960s thin conventional slabs on Blackland clay cracking at corners and heaving over leaking cast iron drains, followed by 1940s pier and beam homes with rotted sills, sunk piers and floors sloping toward the low corner. Harlandale is the south side between South Flores and the Mission Reach: 1940s to 1960s homes in Harlandale ISD on Blackland clay, split between the last pier and beam and the first thin slabs, near Mission San José. Old drains, mature trees and deferred maintenance. 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 Harlandale: 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.
