Burst Pipe? Here Is Exactly What to Do in the First Hour

A burst pipe just turned your home into a clock, and what you do in the next hour matters more than what you do the rest of the week. Most guides you will find hand you a list of causes and a shrug. After 27 years running emergency water calls across El Cajon and East County, here is what we actually tell homeowners on the phone before we roll a truck: there is a fixed sequence for the first 60 minutes, and there is a clear point where DIY stops and you need a plumber and extraction crew. Olympia Services is a licensed California contractor (Lic. 1044933), insured, and available 24/7, so read this, run the sequence, then call and we will handle the part you should not.

Move fast and move in order. A half-inch supply line under pressure can push out several gallons a minute, so every minute the main stays open is more water in your walls and floor. Do not stop to bail or mop first. Stopping the source comes before everything else, and the steps below are the exact order we walk people through while we are en route.

That last point is where homeowners lose the most money without realizing it. You can absolutely handle steps one through five yourself. What you cannot do with a shop vac and a box fan is dry the water that has already wicked into the subfloor, the wall cavity, and the framing. That is where emergency water extraction gets standing water out fast, because our truck-mounted equipment pulls water out of materials a household vac never reaches, and it does it before the 24-to-48-hour window when mold starts.

Your home has two shut-offs that matter, and you want to know where both are before you ever need them. The interior main is usually a valve where the water line enters the house: in San Diego and East County homes that is often in the garage, in a utility closet, or on an exterior wall near the water heater. Turn it clockwise until it stops. The second is the street-side meter valve, out at the curb in a concrete or plastic box, which you turn with a meter key or a crescent wrench when the interior valve is stuck or missing.

Go find both valves today, while nothing is wrong. Turn the interior main a quarter turn to confirm it actually moves, then open it back up. Tag the meter box so a house-sitter or your teenager could shut it in the dark. The single most common thing we hear on emergency calls is that nobody in the house knew where the shut-off was, and the water ran for 20 extra minutes while they searched.

If water is already standing across your floor, the priority shifts from stopping the source to getting the water out and the structure dry, fast. Standing water does not sit still and wait. It wicks up into drywall, spreads along the subfloor, and soaks into framing within hours, and every hour it sits is more material you have to replace instead of dry. The honest gate is this: if the water is more than a thin surface film, or it has reached carpet, walls, or cabinets, you are past what a mop and fans will fix.

When you are on the right-hand side of that table, our crew handles the full arc: our plumbers repair the burst line and pressure-test the system so it does not fail again, and the extraction and drying crew maps the moisture, sets air movers and dehumidifiers, and monitors it until the framing reads dry. And when the break is hidden, water showing up two rooms away from where the pipe actually failed, we run leak detection to find the burst behind the wall instead of opening up drywall on a guess.

Two questions come up on almost every call, both about cost and coverage. Here are the straight answers.
