Slab Leak Detection
Located precisely before any concrete is opened.
About this serviceDallas-Fort Worth
Irving holds two plumbing worlds a few miles apart: post-war slab housing in the south of the city where the copper and cast iron are original, and the towers, offices and hotels of Las Colinas where a single failure closes a floor rather than a bathroom. Both sit on clay that moves inches a season.

The older parts of the city filled in during the 1950s and 1960s, when slab-on-grade with copper supply and cast iron drains was simply how houses were built. Both materials are now at or past the age where they fail on their own schedule, and the clay underneath has been working on them for six or seven decades.
Slab leaks are the largest single category. The soil swells and shrinks seasonally, the slab rides that movement, and the copper cast into it eventually gives at a joint or a fitting. The first sign is usually the water bill rather than a wet floor, so if usage jumps and nothing changed, shut everything off and watch the meter before assuming it is a billing error.
Cast iron drains scale from the inside, thin, and belly where the ground beneath them has settled, so solids collect in the low spot. The signature is repeat backups in the same place: cleared, fine for a while, then back. A camera settles in twenty minutes what symptoms cannot, and frequently shows cracks the scale had been hiding.
Galvanised supply still turns up in the oldest pockets, presenting as low pressure everywhere at once. That is a bore problem rather than a supply problem, the pipe has scaled shut from the inside, and repairs simply move the restriction along.
Irving also has a large, older apartment stock, where the same materials are carrying far more use per fixture than a single-family house does. Cast iron stacks in mid-century multi-family buildings are one of the more common commercial jobs in the city.
Towers, offices, hotels and restaurants change the nature of a plumbing problem in two ways: scale and consequence.
Consequence. A failure in a multi-storey building does not stay where it started. Water finds the floor below, then the one below that, and the cost is rarely the plumbing. It is the finishes, the tenants' equipment and the business interruption. That changes the right approach: isolation valves that actually work and are labelled, known shut-off procedures, and maintenance that is scheduled rather than reactive.
Scale. Commercial kitchens produce grease-laden waste at a volume no residential line ever sees, and the answer is jetting on an interval rather than clearing on an emergency. The interval is set by observation: jet, re-inspect after a few months, and see how much has returned. Busy kitchens often settle on quarterly; lighter operations annually. A well-maintained grease interceptor extends every interval, and a neglected one guarantees the line will need attention regardless.
The arithmetic is worth stating plainly. A scheduled jetting visit happens on a Tuesday morning before service. A backup happens at seven on a Friday evening, closes the kitchen and costs a night's covers on top of the call-out. The maintenance interval is almost always the cheaper number, and it is the one you can plan around.
Commercial properties also carry backflow testing and record-keeping obligations that houses do not, irrigation, boilers, fire suppression and food service equipment all bring assemblies that need annual testing with results filed with the water purveyor. Missing that eventually becomes a notice rather than a nuisance.
Height is its own plumbing discipline, and Las Colinas has plenty of it. Three things behave differently in a tower than in a house.
Pressure has to be manufactured. Municipal pressure will not reach an upper floor on its own, so buildings use booster pumps and pressure zones. When an upper floor loses pressure or an intermediate floor suddenly has too much, the cause is usually in that equipment or its controls rather than in any pipe. Symptoms that read as a plumbing fault, weak flow on twelve, hammering on eight, are frequently one pressure-reducing valve behaving badly.
Water hammer is destructive rather than annoying. A long vertical run of water brought to a sudden stop by a quick-closing valve delivers a shock the whole riser feels. In a house that rattles a wall; in a tower it works joints loose over years. Arrestors and correctly specified valves are cheaper than the eventual joint.
Isolation is the whole game. The cost of a failure in a multi-storey building is almost never the plumbing. It is the finishes, the tenants' equipment and the interruption, on that floor and every floor beneath it. Which means valves that genuinely work, are labelled, and are known to the people on site at 2am are worth more than any amount of pipe quality. It is the single most useful thing to check on a building you manage, and it is regularly the thing nobody has verified since handover.
The same logic applies to Irving's older apartment stock at a smaller scale. Cast iron stacks in mid-century multi-family buildings carry far more use per fixture than a house ever does, and a stack failure affects every unit on the line rather than one bathroom. A camera survey of the stacks tells you what you are managing before a tenant call does.
The phone is answered around the clock, holidays included. 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. On a commercial property, tell us the building type and whether anything is currently being isolated. It changes what we bring.
Dallas County coverage is dense and same-day is normal, with genuine emergencies ahead of scheduled work. Commercial work is scheduled around operating hours wherever possible, because a kitchen line jetted before service costs far less than the same line backing up during it. Pricing is agreed before anything starts.
FAQ
1950s and 1960s slab-on-grade housing with copper cast into the concrete, sitting on expansive clay that moves inches a season. Six or seven decades of that cycling and a joint eventually fails. It is the age of the stock plus the behaviour of the soil.
That is structural, not stubborn. On housing of this era it is usually cast iron that has scaled and bellied where the ground settled, so solids collect in the low spot. A camera identifies which it is and whether the answer is cleaning, lining or replacement.
Whoever is on site at 2am. A labelled valve that the night engineer can find in thirty seconds is worth more than any amount of pipe quality, because the cost of a failure upstairs is the finishes and the tenants below, not the plumbing.
In a tower that is nearly always the booster pump or a pressure-reducing valve on that zone rather than the pipework. Pressure has to be manufactured above a certain height, so when it goes wrong it goes wrong at the equipment. Checking the zone before opening a wall saves a great deal.
Make sure isolation valves work and are labelled, so a failure can be stopped in seconds rather than minutes. Then schedule the things that fail predictably: kitchen line jetting, backflow testing, and inspection of any pipe in unheated stairwells or parking structures before winter.
Set by observation rather than a rule: jet, re-inspect after a few months, and see how much has returned. Busy kitchens often land on quarterly, lighter operations annually. Proper grease interceptor maintenance extends every interval.
If the property has backflow prevention assemblies, and commercial properties with irrigation, boilers, fire suppression or food service equipment do, then yes, annually, by an approved backflow tester, with results filed with the water purveyor.
Common in Irving's mid-century multi-family stock, and they carry far more use per fixture than a house does. Scale, thinning and joint failures are the pattern. A camera survey of the stacks tells you what you are managing before a tenant call does.
In a tall building, yes. A long vertical column of water stopped suddenly sends a shock through the whole riser, and over years it works joints loose. Arrestors and correctly specified valves cost far less than the joint that eventually fails.
Same-day is normal across Dallas County and genuine emergencies go ahead of scheduled work. Commercial jobs are scheduled around your operating hours where possible. You will get a real window rather than an optimistic one.
