Burst and leaking pipe water damage in Las Vegas
Burst pipe water damage starts at the main shutoff, which LVVWD says is usually in the front yard near the sewer riser cap, in the garage or at the home's manifold.

Shut it off, then call
Water from a pressurized line keeps coming until the valve closes. LVVWD tells customers the main shutoff is usually in the front yard near the sewer riser cap, in the garage or at the home's manifold system. Find it before you need it. LVVWD also says the pipes from the meter to the home are the owner's to repair, while a leak in the street goes to LVVWD Customer Care at (702) 870-4194.
Freeze is rare, so look at the other causes
NOAA normals show about 10.7 nights a year at or below 32F at the airport. A frozen pipe is possible on an exposed outdoor line, but it is not the main cause here. Leaks at fittings, supply lines to sinks and toilets, and water heaters are far more common indoor sources. LVVWD rates the water at about 16 grains per gallon, very hard, and scale builds in fixtures and heaters over time.
Opening walls the careful way
We read the wall with a moisture meter before cutting. Where drywall is wet above the drying target, a strip at the bottom comes out so air can reach the cavity. Where it reads dry, it stays. That keeps the rebuild small. The plumber's repair usually needs a permit for concealed piping. The City of Las Vegas lists water piping replacement on its online permits list. Homes in unincorporated Clark County or North Las Vegas use their own permit offices.
The first hour
| Clock | Action | Why |
|---|---|---|
| 0 min | Get people out of the water | Do not walk or drive through moving water. Ready.gov says six inches of moving water can knock you down and one foot can sweep a car away. |
| 2 min | Stop the source if you safely can | For a pipe, close the main shutoff. LVVWD says it is usually in the front yard near the sewer riser cap, in the garage or at the home's manifold. |
| 5 min | Keep away from wet power | Ready.gov says not to touch electrical equipment that is wet or while you stand in water. Leave the breaker panel alone if the floor around it is wet. |
| 10 min | Call or text (702) 602-9420 | Tell us where the water came from, which rooms are wet and whether it came in from outside. That decides the crew and the gear. |
| 15 min | Photograph everything before it moves | Wide shots of each room, close shots of the water line on walls, and the source. Your insurer will ask for these. |
| 30 min | Lift and separate | Move rugs, boxes and furniture off wet floors. Put foil or wood blocks under furniture legs that must stay. |
| 45 min | Treat flood water as dirty | Floodwater can be contaminated, per Ready.gov. Wear gloves and boots. Keep children and pets out. |
| 60 min | Start the 48 hour clock | EPA says to dry water damaged areas and items within 24 to 48 hours to prevent mold growth. Extraction and drying should start inside that window. |
