What Katy homes sit on
Katy is a big city west of Houston that grew from a modest railroad town into a sprawl of 1980s-2010s subdivisions.
The soil under Katy is dense clay, often called gumbo, that swells visibly when wet and cracks when dry. Movement works on the lines under the slab as repeated modest stresses at bends and where a pipe crosses a footing.

The lines under Katy homes
Katy has homes from several decades, so what is under a given floor depends on when it was constructed. The crew covering Katy will want to know what you have already tried.
In Katy, the signs are the same across all three: a warm patch, a rising bill, a hiss at night or a heater that runs more than usual. The 24-hour line takes calls from Katy as well.
In Katy, the technician describes the options in plain terms and does not promise how long any repair lasts. A Katy crew explains the trade-offs before any work is scheduled.
What homeowners notice first
Because the leak is under the Katy floor, owners generally notice its effects first: warmth, sound, a rising bill or a heater that does not rest. In Harris County, crews plan the visit around what you describe on the call.
If a bill beats the same month last year with nothing changed at home, a meter check in Katy is worth doing. Winter bills give the clearest comparison. See warm spots on the floor and a high water bill from a hidden leak for more on each sign. Harris County crews start with the simplest test and work toward the slab.
Say where it is and how long it has been warm.
Living with a slab in Katy
Newer subdivisions grew quickly here. A leak in a Katy home that new is more commonly a single fitting or a damaged spot than general wear. This site does not advise on warranties. It locates leaks and connects you with a crew.
Mature trees close to a Katy home add to movement around a slab by pulling moisture from the soil on one side. Roots can also enter and block drain lines. That is a drain-clog topic this site does not cover. In Harris County, damp ground can hide a leak’s moisture in the soil.
A local crew explains what happens next.
How technicians pinpoint it
A leak technician starts by isolating the hot and cold sides, next pressure tests the suspect line and watches a gauge. These measures narrow the location to a modest area. They do not always give an exact point, and the technician says how sure the result is. See how slab leaks are found.

First steps at home
The one safe check is the meter. Shut off every tap and water appliance, then watch the meter. If it moves, water is leaving the Katy property. For varied-age homes on wet gumbo soil, this is one of the first things a crew asks about.
In Katy, if water is surfacing, shut off the main if you can reach it safely, keep people and pets away from wet areas, move valuables and call. Stay clear of outlets and appliances near standing water. See water meter leak check. Record the meter reading and when you took it, then mention both when you call.
Describe the signs you have seen.

Asked by Katy callers
Yes. Sprinklers and outdoor taps can turn the Katy meter just like a leak, so they are ruled out first. A crew serving Katy can explain what this means for a mixed-era house.
Newer homes do. Older ones may have copper.
A technician can lay out spot repair, a reroute, lining or repiping, and what points toward each for your house in Katy. In mixed-era Harris County houses, the age of the rest of the line shapes the recommendation.
A leak is one possible reason. Other causes include irrigation and toilets that run, and the meter check separates those from a leak. Usage on the bill often climbs before a hidden leak shows any other sign. On gumbo clay over a high water table, crews in Katy look at the whole line, not just one spot.
Sometimes. Whether a line can be rerouted over the slab in Katy depends on the attic, the layout and where the leak sits. A Harris County crew can tell you how long the visit is likely to take.
You describe what you noticed, and we connect you with a local crew. The crew explains what to expect, including how long locating the leak typically takes for your Katy house. Mention that the home is on gumbo clay over a high water table when you call from Katy.
No. For Katy homes, the leak itself is a plumbing problem. Foundation questions go to a foundation contractor, since this site does not assess them. A local crew covering Harris County can walk you through the next step.
In Katy, houses with older lines often do, since the rest of the line is the same age, depending on the home. A technician can discuss rerouting or repiping. Most mixed-era houses in Harris County can be tested without moving furniture far.
Tell the leak technician which rooms are raised. The slab part can have a Katy slab leak. Phones are answered around the clock for Harris County calls.
