Common Signs of Foundation Problems in Waco
- Stair-step cracks in brick or mortar joints
- Doors and windows that stick, rub, or no longer latch
- Sloping or uneven floors you can feel underfoot
- Cracks in drywall around door frames and window corners
- Gaps between walls, ceilings, or countertops
- Cracks in the slab, garage floor, or exterior concrete
- Water pooling against the foundation after storms
Two or more of these on the same side of the house is the classic Waco settling pattern. The elevation survey that confirms it is free.

Our Foundation Repair Process: Inspection to Final Elevations
- Elevation survey and inspection (60–90 minutes, free)
A technician maps your floor elevations with a zip level, walks the perimeter, and checks doors, brick lines, and drainage. You see the map when we do.
- Repair plan and firm bid (Same visit or within 2 days)
Pier type, pier count, locations on a drawing, and the total price. No allowances, no "starting at."
- Engineer letter and permit (3–10 business days)
Inside Waco city limits, foundation work runs through the City of Waco permit process; an independent P.E. letter documents the plan. We handle both.
- Pier installation (1–3 days for most homes)
Crews excavate at each marked location and press or drill piers to depth. Landscaping is set aside and put back.
- Lift, level, and final elevations (Final day)
The house is raised on the new piers to within practical tolerance and a fresh elevation map documents the correction.
- Post-lift plumbing test and paperwork (1–2 days after)
A lift can open old under-slab plumbing joints, so a hydrostatic test after the work protects the repair. You get the elevation maps, engineer letter, and transferable warranty in one packet.
Why Waco Foundations Fail: Houston Black Expansive Clay
Waco sits on the Blackland Prairie, and most of the city is built directly on Houston Black clay, the official state soil of Texas and one of the most expansive soils in North America. It runs 60 to 80 percent clay with a plasticity index that commonly exceeds 50. In practical terms, the top ten feet of ground under a Waco home can swell and shrink enough to move three to six inches between a wet spring and a dry August.
Concrete does not bend that far. The soil pulls away from the perimeter beam in drought and the unsupported edge sinks. That is the foundation settlement behind most Waco repair calls, and it shows up first as stair-step cracks in brick veneer, doors that rub in summer and swing free in January, and cracks radiating from window corners. Our guide to foundation warning signs sorts the serious from the seasonal, and the free survey settles it for your exact house.
Two local facts worth knowing before you hire anyone:
- Permits. Inside Waco city limits, foundation repair is permitted work handled through the City of Waco’s Development Services. The contractor pulls the permit as part of the job, and McLennan Foundation Repair does. Outside city limits, in China Spring and much of the county, there is no municipal permit, so the engineer letter and before-and-after elevation maps become your only paper trail. Insist on them.
- Licensing. Texas has no state license for foundation repair contractors. Anyone with a truck and a bottle jack can call themselves a foundation company here. The substitutes for a license are an independent professional engineer’s report, a warranty that transfers to the next owner, pier depth stated in writing, and a local company that answers the phone in year three. McLennan Foundation Repair builds every job around those four.

A settling foundation does not fix itself, and on this clay the bid only grows with the crack. Call the number above for a free elevation survey, or send the form and we will call you back today.
What Foundation Settling Costs Waco Homeowners Who Wait
A sinking foundation does not pause while you think it over. Cracks in brick and drywall widen through each dry season, doors and windows go from sticking to not closing, and sloping floors pull plumbing and framing along with them. Every summer a settling Waco foundation goes unrepaired, the pier count grows, and so does the bid. Repairs that start around $3,500 can become $15,000 corrections after two more drought cycles.
After Foundation Repair: A Level House and Paper That Proves It
When McLennan Foundation Repair finishes, doors latch again, floors walk flat, and the cracks stop growing. You keep the before-and-after elevation maps, the pier depth logs, the engineer letter, and a warranty in writing. That packet protects your resale price and answers any inspector who ever asks what happened here.
Foundation Repair in Waco: Questions Homeowners Ask
What does foundation repair cost in Waco?
Most single-side slab repairs in McLennan County land between $3,500 and $7,000. Larger corrections with 15 or more piers run into the teens, and whole-house leveling on a badly moved home can reach $30,000. The number for your house comes from an elevation survey. Ours is free, so getting it costs nothing.
Does homeowners insurance cover foundation repair?
Homeowners insurance almost never covers foundation settlement from soil movement, because Texas policies exclude settling caused by expansive clay. The common exception is damage from a plumbing leak under the slab, which is one reason a hydrostatic test is worth doing.
How long does the repair take?
Most homes are done in one to three working days once the permit is in hand, plus a final day for the lift and elevation documentation. Call now and the free survey is usually on the calendar within the week.
Are pressed pilings or steel piers better?
Steel goes deeper and carries more load, which matters on deep fill or heavy masonry homes. Pressed concrete pilings are the workhorse for typical Waco slabs and cost roughly half as much. The right answer depends on depth to stable soil at your address, not on a sales script.
Can I sell my house without fixing the foundation?
Yes, but Texas sellers must disclose known foundation issues, and buyers will price the repair in, usually at a worse number than the actual bid. A documented repair with a transferable warranty typically nets more than selling as-is.
Are hairline cracks in brick or sheetrock an emergency?
Not usually. Hairline cracks that appear in August and close by winter are the clay breathing. Stair-step cracks wider than a quarter inch, doors that stop latching, or separation at the roofline deserve an inspection. If you are seeing those, send the form and we will take a look this week.
Should I water my foundation in a Texas summer?
Consistent moisture around the perimeter helps. Run soaker hoses a foot or two off the slab so the soil stays damp, not soggy. Soaker-hose watering is the cheapest foundation protection available in Central Texas, and watering will not fix a house that has already moved.
Do I need an engineer, or is the contractor enough?
For permitted work inside Waco city limits an engineer letter is part of the process. Beyond that, an independent P.E. who does not sell piers is the one person in the transaction with no reason to inflate the pier count.
Is a permit required for foundation repair in Waco?
Inside Waco city limits, yes. Foundation repair is permitted work through the city, and McLennan Foundation Repair handles the filing as part of the job. In unincorporated McLennan County there is no municipal building permit, which makes the engineer letter and elevation documentation even more important.
How do I choose between foundation repair companies in Waco?
Make every contractor put pier type, pier count, and target depth in a written drawing, then compare drawings instead of totals. Free estimates are standard in this market, so collect two or three, and ask each company to explain any pier the others drew that they left out. The one who answers in soil terms instead of discount terms is usually your contractor.
