Notes from the Castle Hills crew

Castle Hills is the textbook 1950s and 1960s slab. The ranch homes along NW Military Highway and Blanco Road were poured thin, with light reinforcement, directly on the clay-and-chalk transition soil, and the drain lines under them are the original cast iron, which after sixty years has corroded through at the bottom. The classic call here is a kitchen or a hall bath floor that has risen, a crack across a tile floor, or a door in the middle of the house that will not close while the corners of the house have dropped. That pattern, high in the middle and low at the edges, is a leaking drain saturating the clay under the interior while the live oaks in the yard dry the clay under the perimeter, and the hydrostatic test finds the leak more often than not.

Fixing the plumbing comes before the piers, or the piers lift a house that keeps heaving. Enclosed carports and 1970s additions on their own footings pull away from the original slab and crack the joint. Castle Hills is its own city with its own permit office and inspections, small enough that the inspector knows the streets. Most jobs here are pressed concrete pilings around the perimeter, interior piers where a drain has been repaired, and a root barrier on the live oak side.

What we see most

Common foundation problems in Castle Hills

Not generic pain points. These are the patterns behind most Castle Hills evaluations, roughly in the order they land on the schedule.

  1. Cast iron drain lines corroded and leaking under 1950s to 1960s slabs, heaving kitchens and bathrooms

  2. Thin conventional slabs cracking at the corners where mature live oaks dry the clay on one side

  3. Interior heave and exterior drop on the same house, leaving a slab that is high in the middle and low at the edges

  4. Additions and enclosed carports on separate footings moving away from the original slab

  5. The City of Castle Hills running its own permit office inside Loop 410

  6. Something else in Castle Hills?

    Sloping floors, a heaving slab, a crawl space that smells damp, a patio that dropped: if it is the foundation, we can evaluate it. Tell us what the house is doing and when it started.

Before we arrive

Four things that make a Castle Hills evaluation better

Foundation movement on clay is a story told over seasons. The more of it you can show us, the more honest the answer.

  1. Photograph and date

    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.

  2. Check the water

    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.

  3. Find the paperwork

    Previous repair warranties, engineer's letters, the seller's disclosure and any plumbing test. They change the plan and sometimes cover the work.

  4. Send the form

    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.

All questions
How quickly can you evaluate a house in Castle Hills?

Evaluations in Castle Hills 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.

What foundation problems are most common in Castle Hills?

The pattern we see most in Castle Hills is Cast iron drain lines corroded and leaking under 1950s to 1960s slabs, heaving kitchens and bathrooms, followed by thin conventional slabs cracking at the corners where mature live oaks dry the clay on one side. Castle Hills is an enclave city inside Loop 410 along NW Military Highway: 1950s to 1960s ranch homes on thin conventional slabs with cast iron drains underneath and live oaks that were planted with the houses. It runs its own permit office. Drought summers and wet springs move the soil everywhere in the metro, so seasonal cracks and sticking doors show up in every neighborhood.

What does foundation repair cost in Castle Hills?

Typical San Antonio ranges apply in Castle Hills: 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.

Will insurance cover foundation repair in Castle Hills?

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.
