Slab Leak Repair
Clay-side failures repaired, tunnelled or rerouted.
About this serviceDallas-Fort Worth
Fort Worth sits on the seam. East of the city the ground is expansive Blackland clay and slab leaks are routine; west of it the ground turns to limestone and shale, where soil barely moves but every trench costs more. Plenty of Fort Worth houses sit somewhere in between, which is why the address matters as much as the symptom.

Fort Worth straddles a geological change that matters more to your plumbing than the age of your fixtures.
To the east, through Arlington, Haltom City, east Fort Worth and out towards Dallas, the ground is Blackland Prairie clay: highly expansive, swelling when wet and shrinking hard when dry, with inches of vertical movement across a lot between spring and late summer. Slabs ride that, and the copper cast into them and cast iron beneath them fail at joints. Slab leaks are ordinary work.
To the west, through Benbrook, Aledo, White Settlement, Lake Worth and out towards Weatherford, the ground turns to limestone, shale and thin soil over rock. Soil movement drops away sharply, so heave-driven slab leaks become much less common. What replaces them is excavation cost: reaching a sewer line or running a new water service means cutting rock, and that is slow, equipment-heavy work. It is also the main argument for trenchless methods out there, because lining or bursting avoids the expensive part of the job.
Much of the city sits on the transition, with pockets that behave like each. If your neighbours have all had foundation work, you are on the clay side of the behaviour regardless of what the map says.
Fairmount, Ryan Place, Mistletoe Heights, Berkeley, the Near Southside, Arlington Heights' older streets, Polytechnic Heights. Pre-1940 stock, largely pier and beam. Galvanised supply that scaled shut long ago, original cast iron drains, clay laterals to the street. Low pressure complaints here are almost always a scaled-bore problem rather than a supply problem. The saving grace is access: a repipe or drain replacement under a crawlspace is a fraction of the price of the same work under concrete.
Wedgwood, Meadowbrook, Ridglea, Westcliff, Sunset Heights, the 1950s and 1960s belt. Slab-on-grade with copper in the slab and cast iron below it. This is the core slab leak and cast iron replacement population in Fort Worth, and it is at the age where both materials fail on their own schedule.
1970s and 1980s across south and southwest Fort Worth. PVC drains, which eliminates a whole failure category, with copper supply. Water heaters, fixtures and pressure problems dominate the call log.
1990s growth north and northwest, and out through Keller and Saginaw's edges. Polybutylene in real volume, grey flexible pipe with insert fittings that fail suddenly. Worth identifying before it identifies itself.
2000s onward, Alliance corridor, far north Fort Worth, Walsh, the newer west side developments. PEX and PVC, tankless heaters common, attic installations standard in two-storey construction. Failures are workmanship and fixtures rather than fatigue.
There is a length of pipe on your property that almost nobody thinks about until it fails: the water service line running from the meter at the street to where it enters the house. You own it, you maintain it, and in Fort Worth's older neighbourhoods it is frequently the original.
On the deep lots common through Fairmount, Ryan Place, Arlington Heights and the older near-side streets, that run can be sixty or eighty feet of galvanised steel installed before 1950. Galvanised corrodes from the inside, so the failure arrives in two stages. First the bore narrows and the whole house loses pressure gradually enough that nobody notices the decline, people simply come to think of it as a low-pressure house. Then it perforates, and you have water surfacing in the yard or a bill that has doubled.
How to tell it apart from indoor pipe: if pressure is poor at every fixture including an outside hose bib close to the meter, the restriction is upstream of the house. If the hose bib is strong and the indoor fixtures are weak, the problem is inside. That one test narrows it in about a minute and it decides whether you are discussing a service line replacement or a repipe.
Replacement is generally the answer rather than repair, because a perforation in a corroded run tells you nothing about the rest of it. On the clay side of the city it is a straightforward open trench. On the rock side it is the job where trenchless boring earns its money, because trenching eighty feet through limestone is the expensive way to do the same thing. Either way it is worth knowing which pipe you are on before it decides for you.
Slab leaks on the clay side. Meter test, isolate irrigation, pressure test, then locate. Nobody should open concrete before that sequence is done, and the repair decision, spot repair, tunnel, or reroute overhead, follows from what the pipe's history is rather than from what is quickest.
Cast iron drains in the mid-century belt. Repeat backups in one place, scale narrowing the bore, bellies where the ground settled. A camera settles it, and frequently shows cracks the scale had been hiding.
Sewer work on the west side. Where the ground is rock, the conversation starts with whether lining or bursting can avoid the trench, because the digging is the expensive part.
Foundation-related drain failures. Fort Worth has plenty of foundation repair, and the same rule applies as across the Metroplex: test the drains before the lift and again afterwards, so a joint that opens is not an argument about who caused it.
Water heaters, constantly. Hard water, sediment, rumbling tanks, and attic installations that need a pan with a live drain rather than a pan that drains nowhere.
Freeze damage every few winters, in volume. Attic splits and burst hose bibs, discovered during the thaw.
The phone is answered around the clock, holidays included, and the first conversation is diagnostic rather than a booking script: where the water is, when it started, what you have tried, whether the main is off. If it is something you can isolate yourself, we will tell you that.
Tarrant County coverage is dense, so same-day is the normal outcome and genuine emergencies go ahead of scheduled work. Pricing is agreed before anything starts, after-hours rates included.
Before you need us: find the main shut-off and turn it once, then do the same with the cold inlet valve on the water heater. The valves that fail are the ones nobody has moved in fifteen years.
FAQ
On the eastern and central parts of the city, yes. That ground is expansive Blackland clay with inches of seasonal movement. West of the city the ground turns to limestone and heave-driven slab leaks become much less common, though age and workmanship failures still occur.
Rock. Limestone and shale make trenching slow, equipment-heavy work, and the cost sits in the digging rather than the pipe. That is exactly why trenchless lining or pipe bursting is worth pricing against open-cut before committing out there.
Yes, and again afterwards. Lifting a slab moves every rigid pipe through it and can open a brittle cast iron joint. A test before puts the condition on record and a test after shows whether anything changed, without both, nobody can establish responsibility.
Usually galvanised supply that has scaled shut from the inside, so the working bore is a fraction of the nominal size. Repairs just move the restriction along. On pier and beam a repipe is comparatively affordable because everything is reachable.
Substantially. On the clay side of Fort Worth it is a normal open trench. On the rock side, trenching eighty feet through limestone is slow work, and boring the new line in is usually the cheaper route by a clear margin.
Quite possibly if it was built north or northwest during that decade. Look for grey flexible pipe at the heater or a shut-off valve. If it is there and has never been repiped, plan for it. The fittings fail without warning, which is what makes them costly.
Check an outside hose bib near the meter. Strong there but weak indoors means the restriction is inside the house. Weak everywhere including that hose bib means it is upstream. The service line from the meter. It is a one-minute test that decides which job you are looking at.
It can be patched where it perforated, but that tells you nothing about the remaining sixty feet of the same pipe in the same ground. On original galvanised the replacement is the answer; the patch is just a way of paying twice.
Recurring stoppages in one place point at something structural: a belly, roots at a joint, or scale narrowing the bore. Clearing it again buys weeks. A camera tells you which it is and what ending it costs rather than delaying it.
Same-day is normal across Tarrant County and genuine emergencies go ahead of scheduled work. You will be given a real window rather than an optimistic one, plus what to shut off if you are waiting.
