Cibolo, Texas

Foundation repair in Cibolo

Cibolo has been one of the fastest-growing cities in Texas, which means most houses here are recent. That changes the foundation conversation in one important way: if your house is moving, somebody other than you may still be responsible for fixing it.

Start with the warranty, not the contractor

This is the part worth reading even if you read nothing else on this page, and it is the opposite of what a referral site has an incentive to tell you.

New homes in Texas commonly come with a warranty structured in three tiers: about one year on workmanship and materials, two years on major systems, and ten years on major structural components. The foundation ordinarily sits in that ten-year tier. Given when most of Cibolo was built, a great many houses here are still inside it.

Do not let a crew start work first

Structural warranties are typically conditioned on the administrator being notified and given the opportunity to inspect before repairs happen. Having piers installed first can reduce or void a claim that would otherwise have paid for the whole job. If there is any chance your house is still inside its ten years, establish that before anyone touches the foundation. An independent engineer evaluation of your own is fine alongside the claim and often strengthens it.

The order that protects you:

  1. Document. Photograph every crack with something in frame for scale, note the date, and write down which doors stick and when you first noticed. Get an elevation survey — it is a few hundred dollars and it turns "the floor feels wrong" into numbers that can be compared against a later survey.
  2. Find the warranty. Closing paperwork and the warranty booklet. Identify the administrator, which is frequently a third-party company rather than the builder itself.
  3. Notify in writing and follow their stated process. Keep copies. Note that many of these agreements require arbitration.
  4. Get a hydrostatic plumbing test. A leak under the slab moves a foundation by itself, and it is a different claim against a different party.
  5. Get an independent engineer evaluation — the only opinion in this process from someone with nothing to sell you.
  6. Then talk to repair contractors.

Why a nearly new house moves at all

Cibolo sits on the same Blackland Prairie clay as its neighbor — deep, highly expansive Houston Black and Branyon soils. The mechanics of that clay are covered on the Schertz page. What is particular to new construction is why a house can show movement within a few years of being handed over.

Fill that is still consolidating. Rapid subdivision development means lots cut, filled and compacted to a grading plan at speed. Placed fill settles on its own timetable regardless of the seasons, and settles more where it went in deeper.

The slab has not reached moisture equilibrium. This one is genuinely counter-intuitive. A slab poured on clay changes that clay permanently by covering it: the ground under the middle of the house can no longer dry out through evaporation, while the soil around the perimeter continues to wet and dry with the weather. The moisture profile under a new slab takes years to stabilize, and the slab moves while it does.

Drainage has not settled down. Backfill around a new slab compacts for a while and often ends up sloping back toward the house. Young landscaping does not hold soil the way established planting does. Downspouts get left discharging a foot from the foundation. These are cheap to fix and they cause real movement.

Edge lift and center lift

Because of that moisture gradient, slabs on clay deform in two characteristic shapes, and knowing which one you have tells you a lot.

Edge lift is the perimeter rising relative to the middle, so the floor dishes gently toward the center of the house. It is the common pattern in the first wet seasons after construction, when perimeter clay takes on water and swells while the shielded soil under the center has not changed much.

Center lift, sometimes called center heave, is the slower opposite: moisture accumulating under the middle over years until the floor crowns. Interior plumbing leaks produce a localized version of the same shape, which is one more reason to test.

Both are anticipated to a degree by the standards residential slabs are designed to. A measurable amount of either is normal, not a defect. The questions that matter are how much, in what shape, and whether it is still changing — and those are measurements, not something you can settle by looking.

Four common crack patterns in an exterior wall Four brick wall elevations showing a stair-step crack following the mortar joints, a vertical crack wider at the top, a horizontal crack across the middle of the wall, and a diagonal crack running from the corner of a window opening. Pattern 1 Stair-step follows the mortar joints can indicate differential settlement on one side Pattern 2 Vertical, tapered wider at one end the taper is what matters more than the length Pattern 3 Horizontal across the middle of a wall can indicate lateral soil pressure — get this looked at Pattern 4 From an opening 45° from a window or door very common; concerning mainly if it keeps reopening
None of these patterns is a diagnosis. Brick and mortar crack for many reasons, including normal concrete shrinkage and seasonal movement that never becomes a structural problem. What a professional looks at is the combination: how wide the crack is, whether it tapers, whether it appears alongside sticking doors or out-of-level floors, and — above all — whether it is getting worse over months. Only an on-site evaluation can establish what is happening at a specific address.

Defect, or clay doing what clay does?

Movement on its own is not a defect. Slabs are designed to tolerate deflection and expansive clay guarantees they will see some. A defect is movement beyond what the design should have accommodated, or movement traceable to how the house or the lot was built — fill that was not compacted adequately, a slab design that did not match the soil report, grading that sends water at the foundation.

Separating those requires someone looking at elevation data, soil conditions and ideally the original plans, then writing it down in a form a warranty administrator will act on. A repair contractor cannot do that for you, however competent — they have piers to sell and no standing in the claim. This is what a Texas-licensed professional engineer is for, and in a newer home it is the single highest-value few hundred dollars you will spend.

If the warranty has expired

Then you are in the same position as any other homeowner on Blackland clay, and the repair looks like it does across the rest of this corridor: pressed pilings into deep clay, drainage correction to deal with the cause, and moisture management to keep the perimeter from swinging between extremes. The repair methods guide covers how each approach works and when it is the right one.

About these figures

Foundation Repair IQ does not quote prices and does not perform repairs. The figures below are general industry ranges published for orientation only — not quotes, not estimates for your property, and not binding on any contractor. Foundation pricing is set by the contractor after an on-site evaluation, and your actual cost may fall outside any range shown here.

Work General range Notes for a newer Cibolo home
Elevation survey $300 – $800 Spend here first. Creates a baseline to compare later
Engineer's evaluation $400 – $1,000 What a warranty claim actually needs
Hydrostatic plumbing test $250 – $600 A different cause and a different claim
Concrete pressed pilings $300 – $600 each If you are paying yourself, on deep clay
Typical perimeter job $3,800 – $10,000 Commonly 8–18 support points
Post-tension cable locating $300 – $900 Before coring — every house here has cables
Drainage correction and regrading $1,800 – $8,000 Often the highest-value work on a new lot
Downspout extensions and grading touch-up $300 – $1,500 The cheapest intervention that genuinely helps

Estimates for planning only. If your home is inside its structural warranty, the relevant figure may be none of these. See the cost guide and slab repair costs.

General information, not legal or technical advice

This page describes how new homes on Texas clay tend to behave and how builder warranties are commonly structured. It is not a diagnosis of your home and it is not legal advice about your warranty — the terms of your own agreement are what govern, and they vary. Read yours, and take the structural question to a Texas-licensed professional engineer.

Cibolo foundation questions

My house is only a few years old. Can it really have a foundation problem?

Yes, and in a town like Cibolo it is one of the more common calls. The soil does not care how new the house is. Three things specific to new construction can move a recent slab: fill that was placed during grading and is still consolidating, the moisture gradient that develops under any slab poured on clay as the ground beneath it works toward equilibrium over several years, and site drainage that has not settled down yet — fresh backfill compacting around the slab, new landscaping, downspouts still discharging next to the foundation. None of those requires anyone to have done anything wrong. But movement in a house this new raises a question an older house does not: whether somebody else is still responsible for fixing it.

Does the builder warranty cover foundation movement?

Often, and it should be the first thing you check rather than the last. Texas new-home warranties are commonly structured as one year on workmanship and materials, two years on major systems, and ten years on major structural components — the foundation normally falls in that ten-year tier. A Cibolo house built during the growth of the last decade may well still be inside it. Find your closing paperwork and the warranty booklet, identify who administers the warranty (frequently a third-party company rather than the builder), and notify them in writing following their process. Two cautions: many of these warranties require arbitration rather than litigation, and most are conditioned on you not having had unauthorised repair work done first.

Should I get a repair contractor out before I contact the warranty administrator?

Generally no, and this is the single most expensive mistake available to you in a newer home. Structural warranties are typically written so that repairs carried out without the administrator being notified and given the chance to inspect can reduce or void the claim. If your house is plausibly still inside the ten-year window, the sequence that protects you is: document what you are seeing, establish whether the warranty is live, notify the administrator in writing, and let their process run. Getting an independent engineer evaluation of your own alongside that is sensible and does not jeopardise anything. Having a crew install piers before any of it does.

What is edge lift, and is it normal?

Edge lift is when the perimeter of a slab rises relative to its middle, so the floor dishes slightly toward the center of the house. It happens because the exposed soil around the outside of a slab wets and dries with the weather while the soil underneath the middle is shielded from evaporation and stays comparatively stable. Through a wet season the perimeter clay swells and lifts the slab edge. Center lift is the opposite, developing over years as moisture gradually accumulates beneath the middle and crowns the floor. Some of both is anticipated by the design standards slabs are built to, so a measurable amount is normal rather than a defect. What matters is how much, in what shape, and whether it is still changing — which is a measurement question, not a judgment you can make by eye.

What does foundation repair cost in Cibolo?

If you end up paying for it yourself, Cibolo is on the same Blackland clay as Schertz and prices accordingly — concrete pressed pilings commonly $300 to $600 each, a typical perimeter job roughly $3,800 to $10,000. But the cost conversation in a newer home often starts somewhere else. An elevation survey and an independent engineer evaluation together usually come to under $2,000 and may be the only money you need to spend, either because they establish the movement is within normal tolerance or because they give you the documentation a warranty claim needs. Spending on measurement before spending on piers is the right order here. General ranges only — see the cost guide.

How do I tell a builder defect from soil behaving normally?

You generally cannot, and neither can a repair contractor with piers to sell. This is what a Texas-licensed professional engineer is for. Movement by itself is not a defect — residential slabs are designed to tolerate a degree of deflection, and expansive clay guarantees they will experience some. A defect is movement beyond what the design should have accommodated, or a cause traceable to how the house or lot was built: inadequate compaction of fill, a slab design that did not match the soil report, drainage that directs water at the foundation. Distinguishing those requires someone to look at the elevation data, the soil conditions and ideally the original plans, and to write it down in a form a warranty administrator or a court will take seriously.
