Leak Detection Plumbers in Brooklyn, NY
A stain on the ceiling shows where water landed. Where it started is another matter, since water runs along joists and pipes before it drops. In a Brooklyn row house the source might be a pipe, a tub, a toilet, a radiator line or the roof. In an apartment building it is often the unit upstairs, which adds a neighbor and a super to the job. Rain is the other suspect. A stain that shows up after storms and never after showers is a roof, a parapet or a window, and we will say so instead of opening pipes that are fine.

How Our Plumbers Find a Hidden Water Leak
Signs of a Hidden Leak
The water bill jumps with no change in use. The small leak dial on the meter turns with every faucet closed. Paint bubbles, a baseboard swells, a closet smells like a wet basement. One warm stripe on the floor points to a hot water line. Start with the toilets - a silent tank leak is the most common cause of a high bill, and it is toilet repair, which costs far less than opening a wall.
Supply Leak or Drain Leak
This is the question that saves the most plaster. A supply pipe is under pressure and leaks around the clock. A drain leaks only when someone uses the fixture above. So we ask: does the stain grow overnight, or after showers? Tubs leak at the overflow gasket. Showers leak through failed grout and pans. Toilets leak at the floor seal. In winter, a stain that appears only when the heat runs is a steam or hot water pipe, and that is boiler repair territory.

Leak Detection Tools and Tests
Acoustic gear hears water escaping a pressurized pipe through tile and concrete. A thermal camera shows hot lines and wet patches as temperature differences. A moisture meter maps how far the water has traveled. We isolate branches with valves and watch a gauge to find which one loses pressure. Dye in a tub or shower pan confirms a drain leak in minutes.
Underground and Service Line Leaks
A hiss at the front wall with every fixture off points to the water service line. So does a wet spot on the sidewalk that never dries. That pipe runs from the city main to the meter, and DEP holds the owner responsible for all of it. Once the leak is found, the fix is pipe repair. A leak already coming through the ceiling needs an emergency plumber first.
