Supply-line leak under or in the slab
A pressurized hot or cold line leaks into the slab or soil beneath it. These tend to be steady and can wet a large area, so the crew often finds moisture in rooms far from the source.

Slab Leaks
Slab Leak Water Damage: what it covers
Quick answer
A slab leak is a plumbing leak in or beneath a home's concrete slab. A licensed plumber locates and repairs it. The crew deals with the water it released: mapping moisture, drying flooring, cabinets and wall bases, and cleaning up. Celina Water Damage Restoration answers 24/7 for Collin County and nearby towns, and you approve the estimate before work starts.
Most homes in Celina and the towns around it are built on concrete slabs, not over basements or crawl spaces. That is common across North Texas, where the clay soil is too unstable for basements, and many of the slabs are post-tensioned. It also means the plumbing for a kitchen, bath or laundry can run in or just beneath the slab, where a leak is invisible for a long time.
A slab leak does not always flood a room. More often it shows up quietly: a warm spot on the floor, a water bill that climbs, laminate that starts to lift near a wall, or a musty smell with no visible source. By the time anyone sees water, it may have been soaking the slab edge, the subfloor and the bottom of the walls for weeks.
This page explains what the restoration side of a slab leak looks like, what the plumber does and how the two jobs fit together. For the warning signs in a recent house, see the slab leak signs guide, and for the soil side of the story, the blackland clay guide.

Our process
How our slab leak water damage visit works
Shut off the water and confirm the signs
Close the main valve and see whether the meter stops. If it does, a leak in the house lines is likely. A plumber then confirms where, using leak-detection equipment that the crew does not carry.
Map the moisture
Meters and a thermal camera show where water has spread through flooring, cabinet bases and wall bottoms. The readings go to the plumber and, if you choose, to your insurer.
Remove standing water and wet materials
Pad and flooring that have soaked are lifted, and baseboards come off so wall bottoms can dry. Hard floors laid directly on the slab, such as tile, can often stay.
Coordinate with the plumber
Plumbing repairs may mean cutting the slab or rerouting the line through the attic or walls. Both can add water or dust, so the crew and the plumber need to agree on the order of work.
Dry the structure
Air movers and dehumidifiers run, sometimes with mats under flooring that can be saved. The slab itself dries slowly, so the crew re-checks readings until the floor and walls reach dry goal.
Clean up and plan repairs
Once the readings are good, the area is cleaned and the crew can describe what needs replacing. New flooring and drywall are quoted separately.
Cost
How much does slab leak water damage cost in Celina?
A slab leak comes with two bills: the plumber's, for finding and fixing the leak, and the restoration, for the water it released. The plumber's figures below are context only; the crew does not do that work.
| Job | Typical range | What it includes |
|---|---|---|
| Slab-leak detection (a plumber's job) | $150–$400 | Context only, not restoration work |
| Slab-leak repair (a plumber's job) | $2,500–$12,000 | Context only; extreme cases run higher |
| Drying and dehumidifying | $700–$2,000 | Equipment days and monitoring |
| Extraction plus drying, one room, significant loss | $1,500–$5,000 | Floor, cabinet base and wall bottoms |
| Extraction plus drying, several rooms or structural materials | $5,000–$15,000 or more | Leaks that went unnoticed for weeks |
These are typical ranges for the DFW area in 2026, not quotes. The crew confirms the restoration figure on site, and you approve it before work starts. Plumbing is quoted by the plumber.
How do I know it is a slab leak and not something else?
A meter that moves with all fixtures off, a warm spot on the floor, the sound of running water or flooring that lifts for no clear reason all point to a leak in the lines. Only a licensed plumber can confirm that the leak is in or under the slab.
A slab leak can be confused with a roof leak, an irrigation break near the foundation or a water heater problem. A crew's moisture map helps narrow it down, but pinpointing the leak in the slab needs a plumber's equipment.
If the moisture is greatest along one line or at one spot, tell the plumber. It can shorten the search.
Why do slab leaks happen on North Texas clay?
Expansive clay swells when wet and shrinks when dry, and that movement can stress lines under or in a slab. Corrosion and installation defects can also cause leaks. These are general regional patterns, not a reason any one house will leak, and a plumber has to determine the cause at your address.
The blackland soils around Celina move with the seasons. Plumbing that is cast into or laid beneath a slab moves with the ground, and fittings can fail where lines bend or enter the house.
Water that leaks into this soil can also change its moisture content, which is one reason a plumber may recommend a foundation check after a significant leak. That is a question for a foundation specialist, not for the restoration crew.
Does the plumber or the restoration crew come first?
Shut the water off first. Then call the plumber to find the leak and the restoration crew to remove water and start drying. They can work in parallel, but flooring removal and slab work should be coordinated so the plumber has access and drying is not repeated.
If the leak is repaired by rerouting the line through the attic or walls, the plumber may need to open drywall and ceilings. If it requires breaking the slab, the work is dusty and wet.
The crew can share its moisture readings and photos with the plumber, which can save a visit, and with your insurer, which can help a claim. Coverage is decided by your insurer, and many policies treat long-term leaks differently from sudden ones, so ask your agent before assuming.
Is a new home covered if the slab leaks?
It depends on your builder's written warranty and your insurance policy. Texas law describes a statutory minimum for builder warranties, including longer coverage for plumbing than for general workmanship, but each builder sets its own terms. Read your warranty, and call the builder as well as the insurer.
A leak in a newer home may be a warranty matter. Take photos, keep the meter reading and report the problem in writing, since many warranties have notice requirements.
See the builder warranty guide and the new construction water damage page for more, and remember that none of this is legal advice.
Options
Types and options for slab leak water damage
Drain-line leak in or under the slab
A drain line leaks only when water runs through it. The water may be gray or contaminated, which changes how porous materials are handled and may call for the steps on the sewage cleanup page.
Leak at a slab-edge penetration
Lines enter the house through the slab edge, and a leak there wets the wall base and the flooring at the perimeter. These may show up as a damp baseboard on an exterior wall.
Collin County
Why slab leak water damage is different in North Collin and Denton counties
Slab foundations are the norm across Celina, Prosper, McKinney and the towns between, and the blackland clay under them moves with the seasons. That is the backdrop for slab leaks here, and it is why a leak can go unnoticed: the water goes into the soil and the slab edge, not into a room you walk through.
Newer communities such as Light Farms, Windsong Ranch and Trinity Falls are young enough that some homes may still be under a builder's written warranty. If yours is, a slab leak is worth reporting to the builder in writing, in addition to your insurer. The warranty length is whatever your own paperwork says.
Weather affects the timing. A long dry spell in summer shrinks the clay, and heavy spring rain swells it again, so people often notice leaks after a change in weather. That is a pattern, not a rule, and it does not mean the weather caused your leak. If the water meter is moving, the leak needs a plumber regardless of the season.

FAQ
Slab Leak Water Damage FAQs
Can the restoration crew find the slab leak?
The crew can show where the moisture is, which helps narrow the search. Finding the exact leak in or under the slab and repairing it is plumbing work for a licensed plumber.
Will I have to replace my flooring?
Sometimes. Tile on the slab often survives, while laminate, vinyl plank and engineered wood that have soaked usually do not. The crew checks readings before deciding what can be dried in place.
How long does it take to dry a slab?
Concrete holds moisture, so the slab can take longer to dry than the materials above it. The crew re-checks readings and tells you when the floor is ready for new flooring.
Will my insurance pay for a slab leak?
That is decided by your insurer under your own policy. Many policies treat sudden leaks differently from long-term seepage, and some exclude certain slab-related costs. Ask your agent, and keep photos and readings.
Does a slab leak mean my foundation is failing?
Not necessarily. A leak can be a plumbing defect on its own. If you see cracks, sticking doors or sloping floors, a foundation specialist can say whether the soil or slab is moving.
What does cleanup cost without the plumber?
Drying and dehumidifying commonly run about $700 to $2,000 in the DFW area, with bigger losses costing more. The crew gives you a figure on site and you approve it before work begins.
