A burst pipe, a failed supply hose, or water suddenly pouring where it shouldn't — the first minutes decide how bad this gets. Most water damage isn't caused by the initial leak; it's caused by the 30 minutes of inaction while everyone figures out what to do. Memorize this sequence now, while everything is dry.
Minutes 0–2: Where is my main water shutoff, and how do I turn it off fast?
The single most important thing in your home is knowing where the main shutoff valve is before you need it. It's usually where the water line enters the house — garage wall, utility closet, or near the water heater — or at the meter box by the street. A gate valve turns with a round handle (several full turns clockwise to close); a ball valve has a lever (quarter-turn so it's perpendicular to the pipe). Go there now — figuratively — and make sure every adult in the household knows the location and how it operates. If the leak is clearly from one fixture (a toilet supply line, a sink hose), its individual shutoff valve under the fixture is faster than the main. Turn the water off first, ask questions later.
Electricity first: water near an outlet — what do I do?
Water and electricity together can kill. Treat this as the top safety priority. If water is dripping near outlets, switches, light fixtures, or the electrical panel, do not touch any of it — not the water, not the switch, not a wet appliance. If you can reach the breaker box via a completely dry path, cut power to the affected area; if the path isn't dry or you're unsure, don't risk it — leave the area and call an electrician. Never stand in standing water to operate electrical equipment. Once the area is electrically safe, then deal with the water. This order is non-negotiable.
What counts as a real plumbing emergency?
Not every leak needs a 2 a.m. response, and knowing the difference saves panic. Act immediately for: active flooding that the shutoff hasn't stopped, sewage backing up into the home, water pouring through a ceiling (which can collapse under the weight — stay out from under a sagging, bulging ceiling), or no water at all combined with freezing risk. Can wait until morning (with the water off and the area contained): a slow drip from a fixture, a small contained leak under a sink with a bucket under it, or a damp spot that's stable. When in doubt, shut the water off and call — a professional can triage by phone.
Should I document the damage before cleanup?
Yes — quickly, and without delaying mitigation. Take phone photos and video of the leak source, the water's path, and every damaged area before you start mopping up; capture wide shots for context and close-ups of damage. Save receipts for any emergency spending (fans, dehumidifiers, plumber visits). Insurers want to see the damage as discovered, but they also expect you to mitigate promptly — document first, then start drying. Move valuables, lift furniture onto blocks or foil, and get air circulating. The first 24–48 hours determine whether damp drywall dries out or becomes a mold problem.
What NOT to do
A short list of common mistakes: don't use a household vacuum on standing water (electrocution risk — that's what wet/dry vacs are for, used only when electrically safe); don't ignore a sagging ceiling — waterlogged drywall is heavy and can collapse without warning, so keep people and pets clear and don't poke at the bulge to "let it drain"; don't crank the heat to maximum hoping to "dry it fast," which can warp wood and feed mold in hidden cavities; and don't delay calling because it's the middle of the night — that's exactly what 24/7 service exists for.
What to do next
Once the water is off and the area is safe, the question becomes where exactly did it come from — especially if the source isn't obvious.
