A burst pipe needs two things in order: stop the water, then fix the failure properly. If you can reach your main shutoff, close it before anything else. When our technician arrives, usually 30 to 60 minutes after your call, we confirm the system is isolated, find the failed section in the wall, ceiling, garage or yard, and tell you what caused it. In the Las Vegas Valley that is more often age and material than frost. Polybutylene from the 1970s to early 1990s fails at its fittings, galvanized steel in older homes corrodes through from the inside, and exposed lines can still freeze on a cold night.
What failed decides the fix. A single split on otherwise sound copper or PEX is a section repair, and our trucks carry common parts so many repairs finish in one visit. A burst on polybutylene or corroded galvanized usually signals the rest of the system is near the same point, and we will say so plainly and show you the removed pipe so you can judge for yourself. If the loss is under the floor rather than behind a wall, Slab Leak Detection & Repair or Electronic Leak Detection locates it before anything is opened.
You get a written price before work starts, the repair is pressure tested before we leave, and we follow up afterwards. If the burst points to a failing system, a Whole-House Repipe may be the longer-term answer. For a burst at any hour, call (702) 438-3357.
