Who to Call When Your Basement Floods

When to call 911 instead of anyone else

Before any of the calls below, rule out a true emergency. If there is an immediate threat to life or safety, if the water is visibly interacting with electrical systems, sparking outlets, a submerged panel, or if you see structural damage or a real risk of collapse, that is a 911 call, not a basement flooding call. Get everyone out and call from a safe spot outside the house. Everything else in this guide assumes the basement is flooded but the situation is not that kind of emergency, and our Brooklyn restoration crew can walk you through the rest once it's safe.

Once life safety is not in question, the next step is figuring out which of four different people actually handles your situation, since a flooded Brooklyn basement can come from four completely different directions and each one has a different fix.

The electrician or your utility, if water is near the panel

Water and electricity are the first thing to check, before you decide anything else. If standing water is anywhere near your breaker panel, an outlet, or a plugged in appliance, do not walk into the basement to check it yourself. Call an electrician, or call your electric utility if you cannot safely tell whether the panel itself is affected. They can confirm the power is safely cut before anyone, including us, goes back down there to deal with the water.

This call has nothing to do with why the basement flooded. It exists purely to make the space safe to enter. Once power is confirmed off or the panel is confirmed dry, you move on to figuring out the actual source.

The plumber, if it is a supply line or your own sewer lateral

If the water is coming from inside your own plumbing, a burst supply pipe, a failed water heater, a washing machine hose, or a backup from your house's own sewer lateral line, that is a plumber's job. A licensed plumber can shut off the source, clear a clog in your own line, or replace whatever failed. Plumbers themselves draw exactly this line: if the flood is a plumbing problem inside your house, a plumber stops it at the source.

Here is the test that tells you it is your line and not the city's. If the backup only affects your house, and neighbors on the same block are not reporting the same thing, the problem is almost always on your side of the property line. Your own sewer lateral, the pipe that runs from your house to the street main, is your responsibility to fix, and a plumber is who does that.

The city, for a sewer main problem

Brooklyn runs on a combined sewer system in a lot of older neighborhoods, meaning stormwater and sewage share the same pipes. During a heavy rain event, that system can get overwhelmed, and when the main under the street backs up, it pushes water up into the lowest point it can find, which is usually your basement floor drain. If several houses on your block are dealing with the same backup at the same time, or if you can see water coming up out of the street or a catch basin, that points to the city's main, not your own line.

NYC's own emergency guidance is direct about this. Call 311 if your basement or street is flooded or the sewer is backing up into your home. You can also report it to NYC DEP, since they are the agency responsible for the sewer mains themselves. Reporting it does two things: it gets the underlying problem looked at, and it puts an official record on file, which matters later if you are dealing with insurance or a landlord dispute over what caused the damage.

Us, the water damage restoration company, for the actual cleanup

None of the calls above get the water out of your basement. An electrician makes it safe to enter. A plumber stops a supply line or clears your own lateral. The city addresses a main line backup. But the standing water, the soaked carpet, the wet drywall, and the clock running on mold growth are still sitting there after all three of those calls are made. That is where we come in.

We extract standing water, pull out what cannot be saved, and dry the structure itself, tracking moisture in the framing long after the puddle on the floor is gone. If the flooding involves sewage or backed up wastewater from either your own line or the city main, that changes how the cleanup has to be handled, since contaminated water needs different equipment and protocols than clean water from a burst supply line. That is sewage cleanup, and it is not a job for a wet vac from the garage.

For a basement full of clean or gray water from a sump pump failure, a supply line, or heavy rain seepage, that is basement flood cleanup, extraction and structural drying built for a full basement rather than a small spill. And if the situation is still unfolding, water actively rising, multiple rooms affected, or you just need someone on site fast, call for emergency water removal and we will get equipment moving toward you. Call (347) 853-8827 and describe what you are seeing. We will tell you honestly whether you need us, a plumber, the city, or some combination of the three.

Where insurance fits into all of this

Your insurance agent is not who stops the water, but they are worth calling early, ideally right after you have taken photos of the damage. Coverage usually depends on the source. A sudden pipe burst is often covered under a standard homeowners or renters policy, while water that enters from outside groundwater, a storm surge, or a city sewer backup frequently falls under separate flood insurance or a sewer backup rider, if you carry one. Photograph the standing water, the source if you can see it, and the damaged belongings before anything gets moved or thrown out, then call your agent to find out what your specific policy actually covers.
