Floors sloping, dipping, or bouncing? We measure them free – call Brazos Foundation Repair at (254) 503-5077
An uneven floor is a support problem, not a flooring problem, and in Waco it has two different causes. On a slab-on-grade home the concrete tipped or dished because Blackland Prairie clay swelled and shrank under it. On a pier-and-beam home the concrete is fine and the wood floor above it dropped – settled piers, a rotted beam end, or undersized joists. More than about 1 inch of fall across 20 feet is worth measuring. Repairs run $4,500-$12,000.

A slab floor slopes because the soil under part of it changed volume and the concrete followed. Blackland Prairie clay has a high plasticity index – it swells when wet and contracts hard in drought. Around Waco the active zone, the depth seasonal moisture reaches, runs 6 to 10 feet. The movement is never even: one corner sits under an oak pulling water from the clay, the other takes roof runoff from an unextended downspout, and the difference tips the slab.
Two patterns show on an elevation survey. Perimeter settlement drops the outside edge, so the floor runs downhill toward an exterior wall. Center dishing drops the middle while the perimeter holds, leaving a void under the concrete, and often traces to an under-slab leak.
Slab floors do not bounce. Concrete has no spring in it.
Pier-and-beam floors sag because the wood structure between you and the ground lost support or lost strength. Older Waco neighborhoods are full of these homes, and the failure is almost always in the crawl space.
Bounce and slope are separate symptoms: a floor can be dead level and still bounce, or solid and still slope 2 inches.
You can get a usable number in 20 minutes. Measure across the longest open run in the house – a slope only means something across distance.
Our own inspection shoots elevations on a grid every 8 to 10 feet, and that map sets pier count and target lift.
Sort a slab problem from a pier-and-beam problem before anyone quotes you a price.
| What you notice | Slab-on-grade cause | Pier-and-beam cause | Typical fix |
|---|---|---|---|
| Steady fall toward an exterior wall | Perimeter settlement in drying clay | Perimeter pier line settled | Piers on the low side, or re-shim |
| Low dish in the middle of the house | Slab settlement over a void | Interior pier sunk or pad broken | Interior piers and void fill, or new pads |
| Springy, bouncy floor | Rare – loose flooring over concrete | Over-spanned joists, decayed wood | Sister joists or add a mid-span beam |
| Soft spot near a tub or toilet | Under-slab leak washing out support | Rotted subfloor and joist | Leak test, then replace the wood |
| Hump or ridge across a room | Clay heave from swelling soil | Pier or beam splice too high | Moisture control, selective re-shimming |
If symptoms cluster on one side of the house and travel with sticking doors and windows or new foundation cracks, it is real movement. Full list: signs of foundation problems.
A crawl-space inspection is the fastest diagnosis in this trade: the whole structure is visible, so nobody guesses what sits under concrete. We crawl the footprint with a light, a moisture meter, and a probe, and document:
You leave with a list of specific support points – see our pier and beam repair page.
Most whole-home floor leveling in Waco lands between $4,500 and $12,000. Crawl-space work costs far less. Pier count drives the number, and it comes from the survey.
| Repair option | What it does | Typical Central Texas range |
|---|---|---|
| Crawl-space re-shim and re-level | Resets piers, closes gaps at beams | $1,500-$4,000 |
| New interior support pad and post | Adds a support point on a long span | $250-$800 each |
| Sister or replace joists | Restores stiffness, stops bounce | $100-$300 per joist |
| Beam repair or replacement | Replaces rotted or split beams | $50-$120 per linear foot |
| Pressed concrete pier | Cylinders driven under the footing | $300-$900 per pier |
| Steel push pier | Driven to load-bearing strata | $700-$1,200 per pier |
| Vapor barrier and drainage | Stops what rots the wood | $1,500-$6,000 |
Fixing the wood without fixing the water wastes money: if the crawl space stays wet, the new lumber rots too. See our foundation repair cost in Waco guide, house leveling, and foundation leveling.

Sometimes the floor has always been like that. A slope that has not changed and carries no other symptoms is usually how the house was built, and we say so at no charge rather than sell piers. Signs the slope is original:
Damage is progressive; construction is static. That is the test. On an older Waco home, a 1-inch slope with no active signs is a monitoring plan, not a repair. Some lenders or buyers ask for a third-party structural report at closing – we will say if that applies. USDA NRCS soil survey data and Texas A&M AgriLife Extension guidance agree on the cheapest fix: keep moisture around the house even. See
Most floor-leveling jobs in Waco finish in 2 to 4 days. A slab lift on 8 to 14 pressed concrete piers is usually two days; beam or joist replacement adds time. Heavy rain in saturated clay costs a day.
Insurance usually does not cover it – Texas policies generally exclude earth movement. A sudden burst supply line that washed out support is sometimes partly covered, so read your policy.

How much floor slope is too much? Under about 1 inch across 20 feet is common and usually not structural. Between 1 and 2 inches deserves a measured elevation survey. More than 2 inches, or a sharp dip, needs prompt attention.
Why are my floors bouncy but not sloped? Bounce is a stiffness problem, not a settlement problem. It points to pier-and-beam framing – joists spanning too far, decayed wood, missing mid-span support – not a foundation that dropped. Slab floors do not bounce.
Will the floor go back perfectly flat? Leveling lifts the floor toward its original elevation. We lift to the maximum safe recovery, not always dead level, because an aggressive lift cracks drywall, tile, and trim.
Why do my Waco floors feel worse in dry summers? In drought, Blackland Prairie clay shrinks and the soil under the foundation drops away. Settlement and sloping commonly worsen through hot, dry Central Texas months.
Should I fix the crawl-space moisture or the structure first? Both, in the same scope. Replacing rotted wood while the crawl space stays wet just restarts the clock. We correct drainage and add a vapor barrier with the support work.
Do you charge for the inspection? No. It is free and includes floor elevation readings, a crawl-space walk where access allows, and a written assessment.
