Common Questions
How much does foundation repair cost in San Antonio?
There is no standard price, because the work follows what the measurements show: how far the house has moved, how many support points it needs and how deep they have to go. Deep clay on the east side usually means deeper piers than shallow limestone up north. San Antonio Foundation Fix measures first and quotes in writing. Start with an inspection.
What are the first signs of foundation problems in a Texas home?
Doors that stop latching, diagonal cracks running from the corners of door and window frames, stair-step cracking in brick, sloping floors and soil pulling away from the slab edge in late summer. One of those alone is usually nothing; several together is a pattern. See what to look for.
Which foundation cracks are serious and which are normal?
Fine cracks in the middle of a drywall panel are usually cosmetic. Cracks that run diagonally from a door or window corner, step up through brick mortar, or keep widening month after month are the ones that point at movement. Width and change matter more than length. Read how to tell them apart.
Should I use pressed concrete or steel piers on my house?
It depends on the ground under your property rather than on preference. Pressed concrete is common on the deep clay south and east of San Antonio, while steel is often chosen where limestone is shallow or the depth is unpredictable, such as graded hillside lots. Compare the two pier types.
Who does foundation repair near me in San Antonio?
San Antonio Foundation Fix covers San Antonio and the surrounding communities including Alamo Heights, Stone Oak, Helotes, Schertz, Converse, Leon Valley and Castle Hills. Coverage is confirmed by full property address rather than by city name alone. See the service areas.
Why do foundations move so much in San Antonio?
Much of Bexar County sits on expansive clay that swells when wet and shrinks through a dry summer, so the ground under a house changes volume with the seasons. North of the Balcones fault line it turns to limestone and caliche, and houses that bridge rock and clay move unevenly. See how slab repair works.
Can foundation problems be fixed without piers?
Sometimes. If the movement is seasonal and mild, getting roof water away from the wall, regrading and keeping perimeter soil moisture steady can settle a house without structural work. If the slab has dropped and stayed down, that will not lift it. See drainage and root barrier work.
Do I really need to water my foundation in a Texas summer?
On clay soils it genuinely helps, because the aim is to stop the ground swinging between saturated and bone dry. Keep a soaker hose a consistent distance from the slab all the way round, and check the current SAWS drought stage first, since the rules change. Read how to do it properly.
Is it safe to jack up a sagging floor myself?
No. Lifting any part of a house without knowing where its loads run can crack walls, break lines beneath the floor and cause injury. It also makes the eventual repair larger. Keep off floors that feel soft and have the house measured instead. See pier and beam repair.
Should I repair the foundation now or wait and watch it?
That depends on whether the movement is still active. Photograph cracks with a date, mark their ends and re-check in a few months, or have elevation readings repeated after a season. Stable cracking can be monitored; widening cracking should not be. Work through the decision.
What happens during a foundation inspection?
Elevation readings are taken across the floor room by room, cracks are surveyed inside and out, and drainage, grading and nearby trees are reviewed. You get the findings in plain language, including when the answer is that no repair is warranted yet. See the full process.
Do I need a structural engineer or a foundation contractor?
For most assessments a contractor inspection is enough. For a purchase, a dispute or a large quote, an independent structural engineer engaged directly by you gives an evaluation with no interest in selling the repair, and a reputable contractor will not object. See what an inspection covers.
Will foundation repair stop my house moving permanently?
No one can honestly promise that. Piers support the sections they are installed under, but the soil around the rest of the house keeps responding to wet and dry seasons. That is why drainage and watering still matter after repair. See how piers are installed.
Are cracks in an old pier and beam house a problem?
Not automatically. Many older San Antonio homes moved decades ago, settled, and have been stable since. What matters is whether the floor is still moving now and whether beams or piers underneath have decayed or crushed. See service for older neighborhoods.
Can a newer home have foundation problems?
Yes. Uneven fill under a graded pad, drainage running the wrong way and shallow rock under only part of the house produce the same cracking in a 2005 home as in a 1975 one. Build year tells you less than the readings do. See service in newer subdivisions.
Do tree roots cause foundation damage?
Large trees rarely lift concrete, but they draw a lot of moisture out of clay in a dry summer, which lets the soil on that side of the house shrink. A root barrier is usually a better answer than removing a mature tree. See root barrier work.
Can a plumbing leak under the slab cause foundation movement?
It can. A line leaking beneath a slab keeps one area of soil wet while the rest dries out, and uneven moisture is what moves foundations. If a leak is suspected it needs locating and repairing by a plumber before structural work is planned. Get the house measured first.
Do you repair commercial buildings as well as houses?
Yes. Retail units, offices and light industrial buildings sit on the same ground, and the work is staged around trading hours with documentation for owners, managers and lenders. See commercial foundation repair.
