Supply line burst in a wall
Water runs down inside the wall cavity and out at the baseboard, so the first sign may be a damp floor along one wall. Meters find how high the wetness goes, and the wall is opened at the point readings turn dry.
Water extraction and drying after a supply line splits in a wall, attic or ceiling, with the pipe repair left to a plumber.

After a pipe bursts, shut off the main water valve first, then call. The crew removes standing water, finds hidden moisture in walls and ceilings with meters, cuts out what cannot dry and sets drying equipment. A licensed plumber repairs the pipe. Phones are answered 24/7, and a crew is dispatched as fast as one is available.
A split supply line is one of the fastest ways to flood a house. A half-inch line under normal household pressure can put out a great deal of water in a short time, and in a slab-on-grade home that water cannot drain downward. It spreads across the floor, runs into the base of every wall it touches and, if the pipe is in the attic, comes down through the ceiling and light fixtures.
This page is about the water that comes after the burst: extraction, finding the moisture you cannot see, removing materials that will not dry, and drying the structure to a measured goal. Replacing the pipe, the fitting or the shut-off valve is plumbing work for a licensed plumber, and it should happen before or alongside drying so the leak is actually stopped.
Bursts come from several causes. Freezing is one, and the frozen pipe water damage page covers the thaw. Others are old fittings, failed connectors, high water pressure and corrosion. The cleanup work looks much the same whatever the cause.
Do not stand in water near outlets, appliances or a power strip, and do not touch a sagging ceiling or walk under one. Keep children and pets out of the room until the water is cut off and the ceiling has been checked.
Burst pipe jobs are priced by how many rooms and how much material the water reached. A single wet room costs far less than a leak that ran for hours through an attic and two floors.
| Job | Typical range | What it includes |
|---|---|---|
| Category 1 (clean water) mitigation, one room or small area | $1,200–$4,000 | Extraction, drying setup and monitoring |
| Standing water extraction, per sq ft | $1.00–$3.50 | Depends on depth and flooring |
| Air mover, per unit per day | $25–$50 | A room often needs several |
| Ceiling water damage repair, one section | $500–$1,800 | Includes texture and paint |
| Wet attic insulation removal and replacement, per sq ft | $1.50–$4.00 | When the burst was in the attic |
These are estimates for the south Dallas-Fort Worth area in 2026, not a quote. The crew confirms your price on site, you approve the emergency stage before work starts, and repairs after drying are quoted separately. The plumber bills for the pipe repair.
Water runs down inside the wall cavity and out at the baseboard, so the first sign may be a damp floor along one wall. Meters find how high the wetness goes, and the wall is opened at the point readings turn dry.
Water soaks insulation, then the drywall, then drips through light fixtures and vents. Many Texas homes have lines and equipment in the attic, so a burst there can reach several rooms below. The ceiling water damage page covers the drying from above.
A braided hose or a connector can give way while the house is empty. The flow is steady and the water Category 1 at first, but the hours pass fast and the amount can be large. See the appliance leak water damage page for that case.

Close the main water shut-off valve, then switch off the water heater if the leak is near it. Stay out of standing water near outlets and appliances, turn off power to the area only if you can reach the panel safely, move small valuables, and photograph the damage before anything is moved.
Know where your main valve is before you need it. In many Texas homes it is near the water meter at the curb or on an exterior wall, and a quarter-turn ball valve closes with a quarter turn of the lever. If it will not turn, call the city water department or a plumber.
Photos of the pipe, the wet areas and your belongings help your insurer. Take them first, and keep the wet items until the crew has seen them.
A moisture meter reads how much water sits inside drywall, wood and flooring, and thermal imaging shows cooler wet zones behind surfaces. The crew follows the readings out from the visible stain until they drop to a dry reference, so the opening in a wall or ceiling is only as large as the water is.
Water behaves in surprising ways. It runs down inside a wall, wicks upward through drywall and spreads under flooring far from the burst. A ceiling stain the size of a dinner plate can sit on top of a wet cavity several feet wide.
Readings are repeated every day of drying. If a spot rises or stays flat, the crew opens it up or adds equipment instead of closing it on a hope.
A standard homeowners policy often covers sudden and accidental water damage such as a burst pipe, but it usually does not cover long-term leaks or flood. Your insurer decides coverage under your own policy. Call your insurer early, keep photos and receipts, and ask your agent about deductibles.
The crew can document the damage for your claim with photos and moisture readings, but it cannot negotiate with your insurer or pay your deductible for you. Texas law keeps contractors out of the adjuster's role.
If you need help with a claim dispute, the Texas Department of Insurance and the Office of Public Insurance Counsel provide consumer help.
It can. The EPA advises drying water-damaged materials within 24 to 48 hours, but that is a guideline, not a deadline, and mold may have started in hidden spots even when surfaces dried in time. Fast drying lowers the risk without removing it, so the crew keeps checking cavities.
A burst inside a wall or attic is easy to catch late, because the first day passes while the water is still out of sight. If you smell mold or see growth after drying, ask the crew about next steps.
In Texas, mold assessment and mold removal are separate licensed jobs on larger projects, so the assessor and the remediator should be two different companies. See the mold remediation page for the rule.
Location drives the cost more than the pipe does. A split in an attic wets insulation and ceilings across several rooms, a line in a wall wets drywall and flooring along one side, and a supply hose at a fixture usually wets one room. The area wet and the drying days set the price, not the size of the burst.
That is why a phone description helps: which room, which floor, whether the water came through a ceiling and how long it ran. The crew explains the emergency-stage price on site before anything starts, and you can say yes or no.
Repairs such as drywall, texture, paint and flooring are priced after the readings show the structure is dry, since nobody can know what is salvageable on the first night.
Close the main valve, then look at whether the ceiling is sagging or water is near outlets. Turn off power to the area only if you can reach the panel safely, and stay out of rooms with water around electrical outlets.
Pumps and extractors pull water off the floor and out of carpet. Taking the water out first cuts the drying time for everything after it.
Moisture meters and thermal tools trace water into wall cavities, under cabinets and up from the floor. A burst in the attic often wets insulation and the ceiling for several feet around the visible stain.
Saturated carpet pad, swollen baseboard, wet attic insulation and sagging drywall are removed. Ceilings that hold water can fail, so they are opened in a controlled way instead of waiting.
Air movers and dehumidifiers run until readings reach a dry goal. You get moisture logs and photos for your insurer, and repairs are quoted after the structure is dry.
Most Mansfield-area homes are slab-on-grade, and plumbing often runs through the attic and interior walls as well as the slab. That puts a lot of water lines above living space, so a burst in the attic can ruin a ceiling and walls on the floor below before anything shows on the floor.
Mansfield went from 56,368 people in 2010 to 72,602 in 2020, so a large share of its housing is recent. Newer homes bring their own burst-pipe causes, such as connectors, upstairs laundry rooms and bathrooms, and plumbing run through exterior walls where a winter freeze can strike.
If your leak came from a hard freeze, the water often only shows when the ice thaws. That case is treated on the frozen pipe water damage page, which also covers the winter checklist for homes in Tarrant County and the south metroplex.

Air movers, dehumidifiers and moisture meters that dry the floors, wall cavities and ceilings water reached in Mansfield slab homes.
A slab leak is a pressurized water line leaking in or under a concrete foundation.
Before a hard freeze, insulate exposed pipes, let faucets drip and find your main shut-off.
A licensed plumber repairs the pipe. The restoration crew removes the water, dries the structure and cleans up. Having the plumber stop the leak first or at the same time keeps the drying from starting over.
Only as much as the readings call for. Water often wets drywall 2 to 4 feet up from the floor, and the crew cuts out to where the meters read dry. A small burst may need no cutting at all.
It starts as Category 1, from a sanitary source, but it can degrade as it sits in materials and warms. That is why speed matters. If it passed through dirty surfaces, it may be treated as Category 2.
Often 3 to 5 days for a room, longer when ceilings, insulation or heavy humidity are involved. The crew checks readings daily and stops when materials reach the dry goal.
Often not, but the noise of air movers and dehumidifiers is constant. If the water came through the ceiling, or the room is unsafe, staying elsewhere for a few days may be easier.
Phones are answered 24/7. A crew is dispatched as fast as one is available, with no promised arrival time. An after-hours fee may apply, and it is explained before work starts.
