Slab Foundation Repair
The great majority of Arlington houses are slab-on-grade, and a low corner shows in the doors first.
Slab Foundation RepairArlington fills most of the gap between Fort Worth and Dallas, and it was built in waves: post-war streets near the center and the university, then subdivision after subdivision pushing south toward I-20 and beyond. Almost all of it sits on the same shrink-swell clay, so the age of your block says a lot before any visit.

Which cracks are cosmetic, which are letting water in, and which are movement that has to be supported.

Where the water goes and what the trees drink usually explains why one side of the house dropped.
Drainage and Root BarriersArlington is large enough that two neighborhoods can present completely different jobs. North of downtown and around the university the housing is mostly 1950s and 1960s, single story, on early slabs with original drain lines and seventy-year-old trees now standing very close to the walls. Head south past I-20 and you are in 1990s and 2000s subdivisions, bigger two-story footprints, some on post-tension slabs, with young landscaping and irrigation running on a timer.
The clay does not change much between the two. What changes is how the house responds to it. An older single-story slab tends to move gradually at the perimeter over decades; a newer, heavier two-story with a sprinkler system soaking one side and a dry shaded side can develop a noticeable difference in a couple of hot summers. Knowing roughly when the house was built, and whether it is one story or two, helps a provider plan the right length of visit.
When the house went up points to the slab type, the drain line material underneath and how old the trees around it are.
Large trees close to a wall and a sprinkler zone that only waters one side are two of the most common causes in this area.
Which doors started sticking, which cracks are new since last summer, and whether any of it has been repaired before.
On an older single-story slab where the movement is along one wall, perimeter supports plus drainage work is usually the whole answer, and pressed concrete pilings are the common choice. On a heavier two-story, or where the low area runs into the middle of the slab, the supports have more load to carry and the method matters more; our guide to pressed concrete versus steel piers sets out the trade-offs.
If the house is post-tension, say so when you call, because the cables inside the slab change where supports can go and how it is drilled. Read about slab repair, ask about an elevation survey, or see the Mansfield page for coverage further south on the same clay.
It depends on how many supports the house needs, how deep they have to go and how easy the perimeter is to reach. A single low corner on a one-story house is at the contained end; a two-story with interior work and tight side yards is at the other. Ask the independent provider to set out the scope, the method and the price in writing after the elevation survey, so you are comparing numbers rather than impressions.
Fort Worth Foundation Repair Pros connects Arlington and nearby Tarrant County callers with independent providers for inspections, underpinning, crack repair and drainage correction. Mention the age of the house and which doors have started sticking when you call. The services page lists what each visit covers.
It depends on the provider. Inspections are set by appointment, and availability depends on the provider and the property location. Call to check current availability. If water is appearing indoors, or a door has jammed shut in the last few days, mention it when you call.
In nearly every case, yes. Slab movement here is slow and houses stay safe to occupy through it. The risks are indirect: a line under the concrete leaking unnoticed and keeping the clay wet, and anyone trying to jack or shore the structure themselves. Do not attempt the second. Get the first checked as part of the inspection.
The readings decide. If the house is close to level and the cracking is seasonal, correcting the grading, extending downspouts and putting in a root barrier can be the only work needed, and it costs a fraction of underpinning. If one part of the house has genuinely dropped and stayed down, no amount of drainage work lifts it back. Honest companies will tell you which one you have.
Because the whole area shares one soil behavior. The clay swells through a wet spring and then pulls back hard during a long dry August, so entire streets show new cracking in the same season and settle again after rain. That is why a single dated set of readings is worth less than two taken months apart, and why measuring a house twice beats selling work off one dry-summer crack.
Mention the age of the house, one or two stories, and what changed this year.
