Foundation Repair in Gunter, TX — Small Town on Big Clay
Serving Gunter From Our McKinney HQ
Gunter Is Growing Fast, and the Soil Isn’t Getting Any Better
We service Gunter out of our McKinney headquarters at 1402 Custer Rd, about 20 minutes south on 289. Gunter has gone from a quiet farming town of around 1,500 people to one of the hottest growth corridors in North Texas. The population has nearly doubled since 2010, the city limits have expanded from under 2 square miles to over 17, and master-planned communities like Platinum Ranch are bringing thousands of new homes to the area. But underneath all that new construction sits the same heavy Blackland Prairie clay that has been causing foundation problems in this part of Texas for generations.
If your doors are sticking, your brick has stair-step cracks, or your floors feel like they slope toward one side of the house, your foundation is probably moving. The clay under Gunter can swell more than 30% when it absorbs water, then shrink hard in summer when the moisture disappears. That cycle breaks slabs. But a single crack doesn’t always mean you need work done. We see a lot of homes where the issue is cosmetic settling that just needs to be watched.
We offer a free inspection with no obligation. Our crew takes elevation readings across your full slab, evaluates your grading and drainage, and checks soil conditions around the perimeter. Everything goes in a written report. If you don’t need piers, we’ll say so. We have done over 20,000 inspections across DFW and Grayson County and walked away from plenty of jobs that didn’t need repair. When your home does need work, we use one of our three engineered pier systems and get most jobs done in a single day.
Gunter is in southern Grayson County, right on the northern edge of the Texas Blackland Prairie. The geology here is dominated by Upper Cretaceous formations — Austin Chalk and Ozan marl layered under deep deposits of dark, high-plasticity clay. The topsoil across most of the Gunter area can exceed 60% clay content, almost entirely smectite. That makes it some of the most reactive soil you can build on. When the ground gets wet, it swells with enough force to push a slab upward. When it dries out, it pulls away from the foundation and lets corners drop.

Blackland Prairie Clay
The clay under Gunter is classified as a high-plasticity Vertisol with deep shrink-swell behavior. During a wet spring, the top several feet of soil can expand over 30%. During a dry July, the same soil contracts and cracks. That constant push-pull cycle is what damages slabs. The darker the soil, the more clay it usually contains, and the soil around Gunter is as dark as it gets.
⛰️
Austin Chalk and Ozan Marl
Beneath the topsoil, Gunter sits on alternating layers of Austin Chalk and Ozan marl. The chalk is relatively stable, but it’s fractured in places, which lets water penetrate unevenly. The Ozan formation above it is a calcareous clay that holds moisture and creates inconsistent bearing conditions. A home’s slab can sit on firm chalk under one corner and soft, saturated marl under the other. That mismatch is what causes differential settling.

New Construction on Raw Land
Gunter’s city limits have expanded from under 2 square miles to over 17 in the past two decades. A lot of that new construction is going up on recently converted farmland and ranchland. When builders clear land and pour slabs, the fill soil underneath doesn’t always get compacted properly. We see new homes in growth areas develop settlement issues within three to five years because the fill is still consolidating under the weight of the structure.

North Texas Weather Cycles
The 2022 drought was brutal across Grayson County. Pastures cracked open, and the clay pulled away from foundations everywhere. Then the rains came back hard and saturated everything at once. That drought-to-deluge swing is the single worst thing that can happen to a slab on expansive soil. We saw a significant jump in inspection requests across the northern corridor that year, including calls from Gunter homeowners who had never seen a crack before.
Gunter’s combination of heavy clay, rapid development on raw land, and unpredictable weather makes it a tough environment for foundations. Drainage plays a major role too. If your gutters dump water at the slab edge, or your lot doesn’t slope away from the house, the damage accelerates. We check drainage on every free inspection.
Signs Your Gunter Home May Need Foundation Repair
Some of these show up slowly over years. Others appear after a single rough summer. If you notice two or more, it’s worth getting a professional look.
→Diagonal cracks running from door or window corners through the drywall or sheetrock
→Interior doors that stick, drag, or won’t latch when they used to close easily
→Stair-step cracking in exterior brick, running along the mortar joints
→Floors that slope or feel uneven when you walk room to room
→Gaps forming between walls and ceilings, or between window frames and the surrounding wall
→A sudden jump in your water bill, which can signal a slab leak caused by foundation movement
A single hairline crack doesn’t always mean trouble. New concrete cracks as it cures, and that’s normal. What matters is whether the slab is actually moving. We figure that out with elevation data across the full footprint of your home. If it’s cosmetic, we’ll let you know and save you the money.
Foundation Repair Systems We Install in Gunter
Recent Gunter Area Project
South Gunter, Built 2019
A homeowner on the south side of town called us about doors that wouldn’t latch and a crack that had appeared above the master bedroom window. The home was only five years old, built on recently cleared farmland. Our elevation survey showed 1.75 inches of settlement along the east perimeter where the builder’s fill soil had compacted unevenly under the slab.
We installed 14 ST3 piers along the east and south sides, brought the slab back within a quarter inch of level, and finished before 2 PM. Total cost was $5,600. The homeowner said the bedroom door closed properly that same afternoon for the first time in over a year.
Every Gunter home is different, and the right pier depends on what the soil is doing underneath. We carry three systems. Your inspector will recommend the one that matches your soil depth, your home’s load, and how much movement has already happened.
Most Affordable
ST1 System
Concrete Pressed Piers
Starts with 1 ft of steel, then all concrete. 11,980 PSI cylinders, nearly 2x stronger than the industry standard. A solid choice for Gunter homes where the Austin Chalk sits close to the surface and the active clay layer is relatively shallow.
Starts with 3 ft of steel, then concrete. Punches through shallow hard layers and reaches about 50% deeper than the ST1. This is our go-to for Gunter homes sitting on deeper Blackland Prairie clay where the Ozan marl creates inconsistent bearing below the surface.
Starts with 10 ft of double-walled steel, reaching about 2x the depth of the ST1. Reserved for severe settlement where the active clay runs deep and the underlying formations are fractured or inconsistent. Some properties in the Gunter area need this because the transition between Ozan marl and Austin Chalk is unpredictable at depth.
Most Gunter jobs wrap up in one day. Our crew digs at each pier location along the perimeter, drives the pier to refusal, and lifts the slab back toward its original position. Steel brackets lock everything in place. Every hole is backfilled and compacted before we leave. You can stay in the home the entire time.
Your free lifetime transferable warranty starts the day we finish. If you sell your house later, the warranty transfers to the buyer at no cost. We also offer 0% interest financing with 6, 12, or 24-month terms and no payments required.

Foundation Repair FAQs — Gunter
Most Gunter foundation repairs fall between $2,500 and $15,000. The final price depends on how many piers your home needs and how far the slab has dropped. We offer 0% financing for up to 24 months with no payments.
Gunter sits on Blackland Prairie clay in southern Grayson County, with Austin Chalk and Ozan marl underneath. The topsoil can exceed 60% clay content, making it extremely reactive to moisture changes. Rapid development on converted farmland means many newer homes were built on fill soil that hadn’t fully consolidated. The 2022 drought-to-flood cycle was especially hard on foundations in this area.
Diagonal cracks in drywall near door and window corners. Doors that stick or won’t latch. Stair-step cracks in exterior brick running along the mortar joints. Floors that slope or feel uneven room to room. Gaps between walls and ceilings or around window frames. A sudden spike in your water bill, which can indicate a slab leak from foundation movement.
Yes. Every inspection is free with no obligation. We take elevation measurements across your entire slab, evaluate your drainage and grading, and check soil conditions. You get a written report with everything we find. If your home doesn’t need repair, we’ll tell you. We service Gunter from our McKinney headquarters at 1402 Custer Rd, about 20 minutes south on 289.
Most repairs finish in a single day. The crew digs at each pier location, presses the piers to refusal, and lifts the slab back toward level. Steel brackets hold everything in place. All holes are backfilled and compacted before we leave. You do not need to move out during the work.
Stratum uses three systems: the ST1 (concrete pressed piers, most affordable), the ST3 (steel and concrete hybrid, most installed in the Gunter area), and the ST10 (deep steel piers for severe settlement or unpredictable subsurface conditions). Your inspector recommends the right one based on your soil and how much movement has occurred.
