A pipe let go and there is water on the floor. Shut the water supply off, confirm the electricity in that area is safe, then photograph the room before you move anything. Those three moves, in that order, decide more about what this loss costs than any drying equipment that arrives later, for reasons the water damage restoration page covers in full. What follows is the order to work in during the first hour, written for the person standing there in wet shoes without a plan.
Shut the water off, even before you find the break
Close the supply first. In a commercial building the main is typically near where the service enters: a mechanical room, a back closet, or the wall on the street side. In older building stock here it sits in a basement corner behind stored material, which is why the time to find it is in the fall and not while it is spraying.
With a frozen line, two things are worth knowing. The break is not necessarily where the ice is. Freezing water expands and drives pressure along the pipe toward a closed faucet, so the split happens at the weak point somewhere in between, which can be in a different room from the frozen stretch. And a frozen pipe can hold while it is still frozen, because the ice plugs its own split. The water arrives when the space warms, which is why the discovery and the cold snap are rarely the same day.
Once the supply is closed, open the lowest faucets on that line to drain what is left in the pipes and take the pressure off. If the failure is on a heating line rather than a domestic line, shut the boiler down as well, instead of letting it keep pushing water into the leak.
Is it safe to walk in?
Not until you know where the water is relative to the electricity. If water is touching outlets, cords, power strips, a panel or equipment that is still energized, stay out and cut power from somewhere you can reach while standing on dry ground. If getting to the breaker panel means walking through water, or if the panel itself is wet, do not do it. Have the utility or an electrician shut it down instead.
Other reasons to stay out: a ceiling that is sagging or visibly holding weight, water that came from a drain or smells like it did, and any space where you cannot see the floor. Wet floors turn slick before they look dangerous, and a wet stair tread is worse than a wet floor.
Photograph everything before you move a single thing
Take the pictures while the room is still exactly as you found it. Nobody who arrives later can photograph what you are looking at right now, and once the mop bucket comes out that view is gone.
Shoot wide first, so each room is identifiable, then move in close. Get the water line on the wall and on furniture legs, the source if you can see it, the ceiling if the water came from above, whatever was sitting on the floor, and the flooring in the doorways where water crossed into other rooms. Take video as well, walking the space and saying out loud what you are looking at. Do not delete the ugly frames.
Keep the failed section of pipe or the failed fitting if it comes out. Photograph model and serial numbers on affected equipment while they are still readable. Write down the time you found the water and the time the supply went off, because a claim file cannot do much with roughly Tuesday.
Get the standing water off, then get air moving
Standing water does damage every minute it sits, so getting it off the floor is the first physical work. On hard floors, a squeegee toward a floor drain and a wet vacuum move water out of the building, while a mop mostly relocates it. On carpet, a shop vacuum takes what is on the surface and no more, so treat it as a stopgap rather than as the extraction. Pulling water back out of carpet, pad and subfloor is a separate job with separate equipment.
Then air. Open interior doors, pull furniture away from wet walls, and run whatever fans the building has. Keep the heat on. Cold materials give up moisture reluctantly, so turning the thermostat down during a winter loss works against the drying and puts the rest of the plumbing at risk of freezing too.
Two cautions. Do not run the building HVAC if water reached ductwork or a return, and do not push wet air into dry parts of the building.
What to move and what to leave alone
Move what is being ruined right now or is about to ruin something else. Leave what needs to be seen, documented or handled with equipment you do not have on hand.
- Move cardboard boxes, paper files and stored records off the wet floor first. Cardboard wicks quickly and a soaked box tears apart when you lift it.
- Move area rugs off wet hardwood, vinyl or carpet. Backing and dye can transfer into the floor beneath, and that stain does not come out.
- Get furniture legs off wet carpet, or put foil or blocks under them, so metal feet do not rust and finished wood does not bleed.
- Unplug and move anything with a cord sitting in water, but only after that circuit is confirmed dead.
- Leave wall to wall carpet in place. Pulling it up stretches it and can cost you the chance of saving it.
- Leave vinyl plank, sheet flooring and tile alone. What is trapped underneath decides whether it stays, and that gets measured rather than guessed.
- Leave sagging ceiling tile and bulging drywall alone. Poking a bulge empties it onto whoever poked it.
- Leave wet contents out of the dumpster until they are photographed and listed. Items nobody recorded are hard to claim.
Who to call, and in what order
Source first, drying second, insurer third.
The first call goes to whoever can stop and repair the source: your plumber, or building maintenance if the building has staff. If you lease, the landlord or property manager gets that same call at the same time, since the shell of the building is their responsibility while the contents are typically yours.
The second call goes to a water removal and drying contractor. You are not asking for a price over the phone. You are giving them enough to send the right people and equipment rather than guessing: the source, the rough extent, and the floor and wall materials involved.
The third call is your carrier, to open the claim, and you want the photographs already taken before you make it. The fourth is to anyone downstream, because water goes down. In a multi tenant building or an apartment, tell the tenant below before they find their own ceiling, and tell the neighbor sharing a wet wall while it is still a courtesy.
What the first hour cannot do, and where to go next
It cannot tell you whether the wall cavity is dry. Surfaces dry first and go on looking dry while the material behind them is still wet, which is a question for meters rather than for feel. It also cannot tell you what is salvageable, which depends on what the water was and how long it sat.
What the first hour does is preserve options: stop the water, make the space safe, document it, remove what is standing, move air, make the calls. Skip the documentation and one of those options is gone permanently.
