Cleanup and drying after a supply line lets go, from copper pinholes in older Phoenix homes to split fittings in attics and exterior walls.

A burst supply line releases water under pressure until the main valve is closed, so the cleanup covers extraction, opening wet walls and drying the structure. Phoenix Water Damage Restoration answers calls 24/7 across Phoenix and Maricopa County and dispatches a crew as fast as one is available; a licensed plumber repairs the pipe itself.
Close the main shut-off valve first, then call. A pressurized line keeps delivering water for as long as it is open, which is why a pipe that fails while a family is at work does more damage than the same pipe failing on a Saturday morning. If the break is under a sink or behind a toilet, the angle stop there is quicker.
Pipes in this city mostly fail for slow reasons. They fail because the water running through them is very hard and the metal around them has been in service for decades, or because heat and sun have worked on a line in an attic, a garage or an exterior wall for thirty summers.
Two trades are needed and they work best in parallel. A licensed plumber repairs or replaces the failed section. The crew handles the water: extraction, removing wet pad and baseboard, opening wall cavities where readings call for it, and drying until the framing and drywall are back to normal.
Because the failure mode is corrosion and age. Phoenix tap water is classed very hard, and decades of mineral scale on the inside of copper tubing leave thin spots that open as pinholes. Heat on attic and exterior lines, plus fittings that outlast their seals, account for most of the rest.
Water here is often described as among the hardest supplied to any large US city. The City of Phoenix Water Services publishes an annual water quality report, which is the place to look up what is actually coming out of your tap rather than taking a number from a softener advert.
Age does the other half of the work. A house finished in 1958 has supply lines approaching seventy years of service, and the fittings, valves and angle stops in it are the original ones unless somebody has been through and replaced them. Soil movement over caliche and clay is also blamed for stressing lines run under a slab.
Shut the main valve to the house first, because that stops every line at once. If the break is clearly at one fixture, the angle stop beside that fixture is quicker. Open a low faucet afterward to drain the remaining pressure, and leave electrical work alone unless the panel is dry.
Find your main valve on a calm day and make sure it actually turns, before you need it in a hurry. Valves that have not moved in twenty years seize, and a stiff valve discovered during an emergency wastes the minutes that matter most.
A water heater is a special case: if the burst is on the hot side or at the heater itself, shut its cold inlet valve and switch off its gas or breaker before draining anything, so the burner or element is not left firing into an empty tank.
A licensed plumber repairs or replaces the pipe, valve or fitting. The restoration crew extracts the water, opens and dries the wet structure, cleans what the water touched and documents the loss. Those are separate invoices, and the two jobs run at the same time rather than one after the other.
If the repair needs a wall or a ceiling opened, that opening is often the same one drying needs, so tell both parties what the other is doing. The crew can close valves, cap a line and start extraction before the plumber arrives, which keeps the drying clock from running while you wait for an appointment.
When a burst line has been quietly leaking first, check for mold on the back of the drywall and inside the cavity. Mold inspection is a moisture-mapped look at a known water source, not a random air sample.
Drywall often can, if it was clean water and drying starts quickly: the sheet is opened at the base, the cavity is ventilated and the board dries in place. Wet fibreglass or blown-in insulation is normally removed, because it holds water against the framing and loses its performance anyway.
The decision comes from readings, not habit. Drywall that reads near a dry reference after a day of airflow stays; drywall that has delaminated, crumbles at the paper or sat in gray water comes out. Keeping a wet sheet to save a few dollars is how a clean-water job becomes a mold job in September.
Baseboard is cheap to replace and almost always comes off anyway, because removing it is the easiest way to get air into the bottom of a wall cavity.
Shut the main valve before you investigate, and never touch a ceiling that is sagging or holding water, because a loaded drywall sheet comes down in one piece. Keep off wet floors near outlets or appliances, and call (833) 490-5225 rather than reaching into a wall to find the break.
The crew confirms the main or the nearest stop is closed and pressure is off, then photographs the break and the wet area before anything is touched. If the pipe is still leaking, you are told exactly what to tell your plumber so the repair is scheduled first.
A pressurized break throws water sideways and upward, so meters and a thermal camera are run over the wall above and either side of the break, the ceiling below it and the cavity behind it. Insulation inside an exterior wall holds water long after the surface dries.
Water comes up off the floor, then baseboard is pulled and the drywall is cut where readings require it, commonly a flood cut a couple of feet up the wall. Wet insulation comes out, because insulation that stays wet keeps the framing wet.
Air movers push air through the open cavity while a dehumidifier takes the moisture out of the room, and drying mats handle a tile or wood floor over the slab. Readings are repeated at the same marked points each visit, so progress is visible rather than assumed.
Once the wood, drywall and slab match a dry reference taken elsewhere in your house, the cut-out is rebuilt: new drywall, tape, texture match, paint and baseboard. That rebuild is quoted separately, and in Arizona it generally calls for a contractor licensed by the Registrar of Contractors.
Very hard water leaves mineral scale inside copper tubing, and over decades thin spots open as weeping pinholes that can let go all at once. Houses from the 1950s and 1960s are the usual ones, and a pinhole that has been weeping quietly often leaves a stain before it floods.
The connection is weaker than the pipe. Soldered elbows, threaded adapters, washer and dishwasher supply connections, toilet angle stops and the plastic crimp fittings in newer PEX systems all fail at the joint, often as a clean split that empties fast.
Summer attics get far hotter than the rooms below, and lines on a garage wall, a roof run to a cooler or an unshaded exterior wall take direct sun for months. Heat and ultraviolet light harden plastic fittings and seals, and a line that has been cycling at that temperature for years splits without warning.
A burst-line job is priced on the wet footprint plus the wall work: how much drywall has to be cut and how many days the cavity needs. The pipe repair itself comes from your plumber on a separate invoice, and is not included in anything below.
| Job | Typical range | What it includes |
|---|---|---|
| Category 1 clean-water mitigation (per sq ft) | $3.00-$4.00 | A per-square-foot range reported by Phoenix-area cost guides for supply-line water |
| Category 1 mitigation, one room or small area | $1,200-$4,000 | A single-room break found quickly: extraction, drying and monitoring |
| Structural drying for one room (3-5 days, equipment and monitoring) | $800-$2,500 | Air movers, dehumidifier and daily readings while the cavity dries |
| Flood cut: remove wet drywall 2-4 ft up (per linear ft of wall) | $3-$8 | Cutting, removing wet insulation and bagging the debris |
| Drywall replacement: hang, tape, texture, paint (per sq ft) | $3-$7 | Quoted after drying, when the final cut-out size is known |
| Antimicrobial application (per sq ft) | $0.50-$2.00 | Applied to framing and surfaces where the water sat before drying starts |
Read these as a starting point for Phoenix jobs in 2026 rather than a quote: they are the ranges a crew plans around, and your number depends on the wet footprint it actually measures. The emergency stage is approved before work begins and rebuild work is priced afterward.
If it's an emergency, call now. For non-urgent burst pipe water damage, send the form and we'll call you back.
The pre-war districts need a gentler approach. In Coronado's 1920s bungalows and the Spanish Colonial and Tudor Revival houses around Encanto-Palmcroft and Willo, walls are plaster and lath rather than drywall, so a leak travels along the lath and the repair is a plaster patch, not a quick cut-and-screw. Those houses may also carry asbestos in old joint compound and lead paint, so an opening gets checked before it is cut.
Post-war slab neighborhoods supply the classic pinhole call. Maryvale, begun by John F. Long in 1954, along with Alhambra, Sunnyslope's 1950s homes, central Mesa and the post-war streets Tempe surveyed from 1945 to 1960, were built with copper that has now spent decades carrying very hard water.
Newer subdivisions fail differently. In Laveen, Ahwatukee and northwest Chandler, supply lines are often PEX with crimp fittings, run through attics that bake all summer, and the upstairs baths and laundries of two-story plans sit directly over bedrooms and ceilings, so a split fitting shows as a stained ceiling rather than a wet floor.

A slab leak is a break in a water line inside or beneath the concrete floor.
Close the main shut-off valve, then open the lowest faucet in the house to drop the remaining pressure. Get people and pets off the wet floor if it has reached an outlet or an appliance, photograph the room, and call for a plumber and extraction. Do not try to patch a pressurized line.
Yes, because a wall is harder to dry than a floor. Water sits in the insulation and against the bottom plate where no airflow reaches it, and a sealed wet cavity in a warm house is the most likely place for mold to start. One opened, metered and dried cavity is much cheaper than rebuilding a wall later.
That is a question for a licensed plumber, who can look at pipe condition, water pressure and how many pinholes you have already had. Some Valley homeowners choose a partial repipe after a second failure. It is not restoration work, and nobody should push you into it while your floor is wet.
A supply line that burst without warning is the classic example of sudden and accidental damage, which standard policies often cover, while a line that had been weeping for months may be treated as seepage and excluded. Your insurer decides under your policy; the crew gives you readings, photos and a materials list to submit.
Because the meter says otherwise. Paint and texture hide moisture well, and the insulation and bottom plate behind the sheet can be soaked while the painted face feels dry. Every cut is marked, explained and photographed first, and the opening is kept to what the readings justify.
Until the framing, drywall edges and floor match a dry reference reading, which commonly means three to five days of equipment for a single room and longer where tile, a mortar bed or plaster is involved. Painting over damp material traps the moisture and the patch fails later.
