A leak in a house is a problem. A leak in a tower is a problem with neighbors, an association, two insurers and a corridor full of people who want to know what is happening.
The first ten minutes matter more than anything a plumber does afterwards, and almost all of it is things you can do yourself.
1. Stop the water
Find your unit’s shut-off. In a condo it is almost always inside the unit — commonly behind an access panel near the water heater, in the laundry closet, or in the ceiling of a hallway closet.
Turn it clockwise until it stops. If it is stiff, use steady pressure rather than force; a valve that snaps is worse than a valve that is stuck.
If you cannot find it, use the local stop under the affected fixture — beneath the sink, behind the toilet. That isolates one fixture, which is often enough.
Find this valve today, not during an emergency. It takes two minutes and it is the single most valuable thing in this article.
2. Open the lowest faucet
Once the supply is off, open the lowest fixture in the unit. The pipes drain downwards into it rather than continuing to empty into your floor.
3. Tell building management immediately
This is the step people skip, and it is the one that limits the damage.
If water is heading into another unit, management can reach that unit when you cannot. They can also shut a riser, which you cannot. In most Miami towers they are also the gatekeeper for letting a contractor in at all — so telling them early starts two clocks at once.
4. Photograph everything before you clean up
Wide shots of the room, close shots of the source, and anything already damaged. Include a timestamp if your phone does not.
This is not about blame. It is that in a month, when responsibility and insurance are being sorted out, the only version of events that counts is the documented one. Cleaning first and photographing second destroys the evidence in the order you need it.
5. Then call a plumber, with a photo
Send a photograph of the leak and one of the pipework around it. That single step decides what goes on the van, and it is usually the difference between one visit and two.
Tell us the building at the same time. Whether the association needs a certificate of insurance, whether the service elevator has to be booked, whether there are restricted working hours — that is often what decides how fast anybody can actually reach you.
What counts as an emergency
- Water coming through a ceiling or running down a wall
- A supply pipe that has burst or is weeping under pressure
- A waste stack backing up into a bath, shower or floor drain
- A water heater leaking from the tank body
- Anything you cannot isolate with a local valve
What can wait until morning
A dripping faucet. A running toilet that is draining away safely. A slow drain that still clears. A water heater that has gone cold without leaking. These cost less in daylight, and nothing gets worse overnight.
The one thing to do today
Go and find your shut-off valve. Take a photo of where it is. Put it somewhere you will find it at two in the morning.
Every emergency plumber in Miami will tell you the same thing, and almost nobody does it until after the first flood.
Who pays, and why it is rarely obvious
Most condo water disputes in Miami are not about plumbing. They are about a boundary written into the declaration years before anyone involved moved in.
The usual division is that the association owns the common elements — the stacks, the risers, the mains running between units — and you own everything from the branch into your walls inward. Usual is not universal. Some declarations put the shut-off valve on your side and the tee behind it on theirs, which is precisely the joint most likely to fail.
Three practical consequences:
- Find out before you need to. Your declaration is a document you can read on a quiet evening. Doing it while water is coming through a ceiling is not reading; it is arguing.
- Damage and cause are separate questions. The association may own the pipe and still not own the ruined floor two units below. That is what the insurance is for, and the claim is much simpler when the cause was established in writing on the day.
- A plumber’s report is worth more than your account. A board asked to act on a description asks for evidence. A board handed a written cause and a photograph usually acts.
What to have ready before you call anyone
Keep these four things somewhere you can find them at two in the morning, because at two in the morning you will not find anything else:
- Where your unit’s shut-off is, and whether it actually turns.
- The building’s emergency number, not the office number.
- Your unit number as the building records it, which is not always the number on the door.
- A photograph of the meter or riser cabinet, so a plumber knows what they are coming to before they arrive.
Our emergency shut-off guide is a one-page version of that list, designed to be filled in and stuck inside a cabinet door.
