A slab leak is a leak in a pipe under or inside the concrete foundation, and it wets floors from below. Finding and fixing the line belongs to a licensed plumber. Lewisville Water Damage Restoration handles the rest: removing water, drying floors, walls and cabinets, and documenting readings. Phones are staffed around the clock, and crews go out in the order they come free.
Slab leaks do not announce themselves with a gush. You notice a warm patch on a floor, a hiss in a quiet room, a water bill that jumped, or flooring that has begun to lift. Shut the main valve, and if the floor-level damage is growing, call.
The pipes in question run beneath or through the concrete of a slab-on-grade house, which is how many North Texas homes are built. Foundation and leak-detection companies describe a pattern in which expansive clay soil swells when wet and shrinks when dry, and that movement stresses lines under the slab. The sources here are those companies, so treat it as a likely mechanism, not a guarantee for any house.
This is a water cleanup service. Finding the leak, breaking into the slab and repairing the line are plumbing work, and foundation questions belong to a foundation contractor. What the crew does is dry what the water reached, which can include flooring, baseboards, lower drywall and the base of cabinets.
Do not drill, saw or jackhammer a slab yourself, since you can hit another line or a post-tension cable. If a floor is warm and the water heater is gas, treat any smell of gas as a separate emergency and leave the house.
A slab-leak cleanup is priced on the area wet, the flooring type and how long it takes the slab and walls to dry. Detection and repair are plumbing costs and are not included here.
| Job | Typical range | What it includes |
|---|---|---|
| Moderate job (several rooms, soaked carpet and walls) | $1,500–$3,500 | A leak that wet one wing of a house |
| Wet carpet pad removal and disposal (per sq ft) | $0.75–$2.00 | Pad over a slab leak stays wet and rarely dries in place |
| Structural drying for one room (3–5 days, equipment and monitoring) | $800–$2,500 | A slab can need more days than a wood floor |
| Category 1 (clean water) mitigation, per sq ft | $3–$4 | Typical for a pressurized supply line |
| Antimicrobial application (per sq ft) | $0.50–$2.00 | Used where water sat long enough to concern a technician |
These ranges set expectations and nothing more. Your technician confirms the figure on site, and the plumber's detection and repair are billed separately by the plumber.
Water from a pressurized line is clean when it leaves the pipe, though it can pick up contaminants as it soaks flooring and sits. It moves under flooring and into wall bases, and the meter keeps running until the line is shut off.
A leak on the hot side can warm the floor above it. That makes the slab feel warm, and the heat plus moisture can speed up damage to flooring adhesive and baseboard.
A break in a drain line under the slab carries wastewater, not clean water, so the cleanup follows contaminated-water rules. The sewage cleanup page explains what that involves.
Tell us what's happening and we'll tell you honestly whether it's a quick fix, and what slab leak water damage should cost.
Expansive clay soil swells when wet and shrinks when dry, and that movement is blamed for stressing lines under slabs. Foundation and leak-detection companies describe this pattern across Denton County, and plastic and copper lines both appear in their accounts. Poor installation, corrosion and old connections can also be factors.
The soil is not the same everywhere. Parts of Denton County are clay-rich, while the western side toward the Cross Timbers may be sandier. A plumber looking at your house is a better guide than a county-wide generalization.
No source tells us what pipe material lies under any particular street or subdivision, and this page does not guess. If you want to know what you have, ask the plumber who finds the leak.
The crew dries what the water reached: flooring, wall bases, baseboards and cabinet bases. It maps moisture with meters, removes materials that cannot dry in place and runs equipment until readings match a dry reference. It does not locate, break into or repair the leak, which is plumbing work.
Water under a slab can find its way up through expansion joints and the edges of the floor. It is rarely a single wet spot. A map of the readings shows whether the water is local or has traveled.
If cabinets have been standing in water, the crew checks the toe kick and the base. Cabinet boxes made of particleboard swell, and once they swell they rarely return to shape.
It depends on your policy. Texas policies often limit or exclude foundation damage caused by plumbing leaks, while water damage to the home may be treated differently. Ask your agent how your policy treats a leak under the slab. The crew's own readings, photos and inventory of removed items are given to you to share.
Two questions come up, and they are separate. One is the cost of the water damage to flooring and walls, and the other is the cost of reaching and fixing the pipe and any damage to the slab. Policies word these differently.
Get the answer from your insurer before you sign off on any work. A claim denial is not a verdict on whether your leak was real, and you can ask for the policy language in writing.
Sometimes for weeks. A small leak under a slab can wet the soil first and then work upward through joints, so floor damage may appear well after the leak began. A rising water bill is often the earliest sign. A plumber's test confirms the leak, and a moisture map shows how far water has traveled.
Because it is hidden, a slab leak often looks like several smaller problems: a damp baseboard, a musty closet, a floor that feels cool one week and warm the next. People often chase the symptoms before they suspect the pipe.
If you see two of the signs at once, shut the main valve for an hour and check the meter. A meter that stops is a strong hint the leak is on your side of the line.
The crew checks the meter and the fixtures to see whether water is still moving. If it is, a plumber is the next call, and the valve stays closed until that plumber arrives.
Moisture meters and a thermal camera show how far water has spread through flooring, wall bases and cabinets. A slab does not drain, so water moves sideways until it finds an edge.
Carpet pad, floating plank and underlayment that trap water against the slab are lifted. Tile is often left, with its edges and grout lines checked.
Air movers, dehumidifiers and sometimes directed air under cabinet toe kicks run while readings fall. Concrete dries slowly, so the visits continue until it matches the dry reference.
You are handed the photographs, the readings and an itemized list of what came out. Rebuilding is quoted after the plumber has repaired the line and the slab is dry.
Slab leaks are one of several kinds of water damage in Lewisville, not the main one. Attic heaters, air handlers and roof leaks bring water through ceilings, while this page is about water coming up from the floor. Many suburban houses here sit on slabs, and the pattern follows the foundation.
The dry-then-wet cycle of North Texas clay is the likely mechanism, and it is worth knowing. After a dry summer the soil shrinks, and a wet spring swells it again. Plumbers and foundation companies connect that movement to pipe stress, though no one can say which house it will happen to.
If your plumber recommends breaking into the slab, ask about permits and a foundation contractor's opinion before the work starts. The burst pipe water damage page describes the pipes that fail above the slab, which is a different problem with a different fix.

Whether a Texas homeowners policy covers water damage depends on the wording of your own policy, which only your insurer and agent can read for you.
A slab leak is a break in a pipe that runs under or inside a concrete slab.
A meter that moves with everything off, a warm floor patch and sound from under the floor point toward the slab. A plumber confirms with a pressure test or electronic detection, and the crew's moisture map can narrow the search.
No. Leak detection and repair are plumbing work. The crew maps where the water has gone, which can help the plumber, and then dries the damage.
Carpet pad and floating plank usually do, because they trap water on the slab. Tile and sealed hard surfaces are often left in place, though the edges and grout are checked.
Many people can, with the main valve closed and water used only as needed. A plumber may ask you to leave it off until the repair, and drying equipment will be noisy and warm.
It can, if materials stay wet. Drying fast and to a written goal limits that risk, and the mold inspection page explains what to do if you see growth.
A leak can stress soil under a slab, and soil movement can in turn crack a line. Whether your foundation needs attention is a question for a foundation contractor, not a restoration crew.
