Nine foundation services for Corpus Christi, priced from cheapest: plumbing test $300–$800, moisture stabilisation $500–$2,500, root barriers $1,500–$6,000, pressed pilings $1,200–$3,000 each. Assessment free.
First, rule something out
A free assessment with floor elevations establishes whether anything has actually moved and in what pattern. Where the pattern is localised and ignores the seasons, a static plumbing test settles an entire category of cause before a penny goes on structural work.
Then reduce the swing
Moisture stabilisation narrows the annual moisture cycle that drives movement here, and a root barrier stops a mature tree undoing that on one elevation. Both are cheap against underpinning and both address the cause rather than compensating for it.
Support only what is left
Pressed pilings carry the beam past the zone that moves with the seasons, and are what you buy when the floor has already dropped and you want it back. Post-tensioned slabs constrain how that work is done and get established before anybody cuts anything.
Moisture Stabilisation
Holding the soil steady, which on this ground is frequently the whole repair.
Pressed Pilings
The regional method, for houses where the swing has already moved something.
Post-Tensioned Slabs
Steel under tension in your floor, and why nobody should cut before locating it.
Root Barriers
A mature tree in a South Texas August is a pump, and the clay loses.
Under-Slab Leaks
Rule this out first, or you will pay to lift a house that a pipe is still wetting.
Checking a Contractor
Texas licenses nobody for this work, so here is what to verify instead.
Watering a Foundation
The maintenance habit this market runs on, and the ways it goes wrong.
Buying a Repaired House
Prior work is common here. The warranty and its transferability are the real questions.
Cost Guide: Foundation Repair Prices in Corpus Christi
A ladder rather than a price list — and a useful number of houses stop on the second rung.
Which rung matches which symptom
| What you are seeing | Likely rung | The work | Range |
|---|---|---|---|
| Cracks that open in drought and close after rain | Reduce the swing | Stabilisation | $500–$2,500 |
| Movement in one spot, no seasonal pattern | Rule out plumbing | Static test | $300–$800 |
| One elevation low, big tree on that side | Stop the drawdown | Root barrier | $1,500–$6,000 |
| Floor measurably out of level, sticking doors | Support it | Pilings | $1,200–$3,000 each |
| Newer house, warning stamped at the garage | Establish this first | Locate the tendons | Before anything else |
| Buying, and prior repair was disclosed | Read the paperwork | Warranty and transfer | Free to review |
Why the order is not marketing
Underpinning a house while a leak is still wetting the clay, or while a tree is still drying one side, buys movement that resumes. The ladder is cheapest-first because that also happens to be correct-first. Full pricing on the cost guide.
Working out which rung
Do I have to work through all of these?
No, and most people do not. The order exists so that the cheap diagnostic steps happen before the expensive structural ones, not so that everybody buys everything. Plenty of houses stop after the free survey.
What if I already know I need pilings?
Then we measure, confirm it and quote it. What we will still do is check the plumbing question first, because underpinning around an active leak is money spent against a force nobody has turned off.
Which step is the diagnostic one?
Two of them are. A static plumbing test rules an entire category in or out for a few hundred dollars. A season of stabilised moisture that changes nothing tells you the seasonal cycle is not what is driving your movement.

Two things help most before we get there: roughly what year the house went up, and whether the trouble showed up during a dry spell or after heavy rain. On this ground the season it appeared in narrows the cause faster than the size of any crack does. Expect a reply the same working day.
