Warning signs
Signs a slab foundation may have moved
Walk the house and note anything on this list:
- A crack in the slab itself, often found when carpet, tile or wood flooring comes up
- Stair-step cracks in brick, especially at the corners of windows and doors
- Interior doors that stick, swing on their own or no longer latch
- Gaps between baseboards and the floor, or trim pulling away from a wall
- Cracked floor tile, or grout lines that keep reopening after repair
- A floor that runs downhill toward one corner of the house
- A water bill that jumps for no clear reason
A crack that keeps growing, or several signs together, is the reason to ask for quotes. See foundation crack repair for how to tell crack types apart.
Hairline or structural
Hairline cracks vs. structural movement
Worth an evaluation
Cracks that widen over months, edges that sit higher on one side, cracks that line up with stair-step cracks outside, or floors that feel sloped.
Mark each end of a crack in pencil and photograph it monthly. Floor elevation readings from the companies that visit show the shape of the whole slab, which says more than one crack.
How it works
How piers lift and support a slab
Elevation survey
Floor readings across the house, plus cracks, doors and drainage. A free evaluation is also a sales visit.
Plumbing check
Many companies recommend a leak test first, since a leaking drain line under the slab can be the cause.
Written proposal
Pier type, count, locations and spacing, the lift goal and drainage work.
Install piers
Crews dig beside the perimeter beam, or through the floor, and drive piers until they meet resistance.
Lift and shim
Jacks raise the beam slowly, then it is set on the piers with caps and shims.
Test and document
Final readings, a second plumbing test where recommended, pier records and warranty terms.
Tyler specifics
Why slabs move in Tyler and East Texas
Many homes in Tyler and Longview sit on a concrete slab poured on the ground, especially houses built from the 1970s on. A slab rides on the soil under it, so when that soil dries, swells or washes out, the slab can follow.
- Mixed soils. Much of Tyler and Smith County is mapped in sandy and loamy soils, many over red clay subsoils with moderate shrink-swell potential (USDA NRCS). That mix means poor drainage, erosion and long dry spells can all move a foundation. Deep sandy lots tend to have more trouble with washout and settling; lots with red clay subsoil can shrink in a dry summer and swell when the rain returns.
- Heat and dry spells. Tyler averages about 42 inches of rain a year, but July is the driest month (2.1 inches) and the city sees about 98 days of 90°F-plus heat (NOAA 1991–2020 normals, Tyler Pounds Regional Airport).
- Drought years. In 2011, all of Smith County was in exceptional drought for 21 weeks (U.S. Drought Monitor), and Tyler had 46 straight days of 100°F-plus heat that summer (NOAA). Tyler got just 25 inches of rain in 2011 and more than 68 inches in 2015 (NOAA).
- Trees and water. Large pines and oaks near the house can dry out clay soil under a foundation in a drought. Short downspouts and leaking pipes keep one side wetter. See drainage and grading.
About half of Tyler's homes were built before 1980 (Census ACS 2020–2024). During dry spells, steady soaker-hose watering near the slab can help keep soil moisture even; follow Tyler Water Utilities' current watering rules. More in why East Texas foundations move and the drought watering checklist.

The pier count drives most slab quotes. Interior piers, flooring repair, plumbing tests, an engineer's report, drainage work and the permit add to it. Quotes for pressed concrete piles vary by company, so ask for the price per pier in writing. The Tyler foundation repair cost guide has a calculator, and piers and pilings compares the pier types you may see.
Is it urgent?
When slab movement needs a quick look
Ask for an evaluation soon if
- Water is coming up through a floor crack, or you hear water running with every tap off
- An exterior door will not close or lock
- A crack is wide enough to fit a coin and has grown in weeks
- Brick is bulging, leaning or pulling away from a window frame
- Gas smell near the foundation: leave the house and call the gas utility first
Most slab movement is slow, so there is time to compare quotes. See foundation inspections.
Before you sign
Questions to ask before you sign
- Who designs the repair, and does a PE review or sign off on it?
- Which pier or support type, how many, and at what spacing, marked on a drawing?
- Is the written estimate itemized, including interior work, drainage, permit and cleanup?
- Ask whether the warranty is transferable if you sell the home, whether there's a transfer fee, and what it covers.
- Can you show proof of liability insurance?
- Who checks whether a permit is needed?
- Do you recommend a plumbing test before and after the lift, and who does it?
- What lift are you aiming for, and will you give me elevation readings before and after?
Texas rules worth knowing
Texas does not issue a state license for foundation repair companies, so check experience, insurance, written warranties and reviews yourself, and ask whether a licensed professional engineer (PE) designs or signs off on the repair.
An independent Texas-licensed professional engineer works for you, not the repair company. You can look up a PE's license with the Texas Board of Professional Engineers and Land Surveyors (pels.texas.gov).
Whether your repair needs a City of Tyler building permit or an engineer's plan depends on the work. Your contractor should check with Tyler Building Services (423 W. Ferguson St., 903-531-1151). In other towns, check with the city's building department. Outside city limits, Texas counties generally don't issue building permits for home repairs.
Texas law gives you until midnight of the third business day to cancel many contracts signed at your home after a sales visit (Tex. Bus. & Com. Code §601.051). Ask whether it applies to your contract and look for the cancellation form.
Questions
Slab foundation repair FAQs
Is a crack in my slab foundation serious?
Not always. Many slabs carry thin shrinkage cracks from curing that never change. Pay closer attention when a crack keeps widening, when one side sits higher than the other, or when it shows up with sticking doors and stair-step cracks in the brick. Photograph it beside a tape measure, write the date on the photo and check again in a month or two.
Why do companies want a plumbing test before lifting a slab?
Water lines and drain lines run under most slabs. A leaking drain line can soften or wash out the soil under one part of the house, and lifting a slab can stress pipes that are already weak. Many companies recommend a plumbing leak test before the lift and again after it so you know whether a leak caused the movement and whether the lift caused any damage.
Do I need a permit for slab foundation repair in Tyler?
Whether your repair needs a City of Tyler building permit or an engineer's plan depends on the work. Your contractor should check with Tyler Building Services (423 W. Ferguson St., 903-531-1151). In other towns, check with the city's building department. Outside city limits, Texas counties generally don't issue building permits for home repairs.
Does a lifted slab go back to perfectly level?
Usually not. Slabs are rarely poured perfectly flat, and lifting too far can crack drywall, tile or pipes. Ask what lift the company is aiming for and for elevation readings before and after.
