Leak detection and water leak repair across Staten Island
Staten Island leaks are house leaks, and many houses here are on slabs or have finished basements where a hidden leak does real damage before it shows. Slab leaks in Great Kills, Eltingville, New Dorp and Tottenville are located with acoustic equipment and either repaired at the spot or rerouted overhead, whichever disturbs less. Houses raised after Sandy sometimes have supply lines in the elevated crawlspace that freeze and split. A high water bill with the meter turning when everything is off is a service line leak under the yard, which we locate before digging.
We dispatch to Staten Island daily; the Verrazzano puts the North Shore 35 to 45 minutes from the shop, and we stage parts for South Shore calls so one trip finishes the job.

Questions from Staten Island
Who finds water leaks near me in Staten Island?
GW Mechanical Corp finds hidden leaks in Staten Island homes and apartments without tearing out walls, then repairs them in the same visit. Call 646-980-2411.
How do I know if I have a hidden water leak?
Check the water meter with everything off. If it moves, water is leaving somewhere. Stains, musty smells and a higher bill are the other signs.
Can you find a leak in Staten Island without opening walls?
Usually we narrow it to a small area first with isolation, pressure testing, dye tests, moisture meters, thermal imaging and acoustic equipment, then make one access opening in the right place.
My neighbor in Staten Island says I am leaking into their apartment. What now?
Call us. We test every fixture, supply line and drain in your unit and determine whether the leak is from your apartment, a riser or the building, with a written report and photos either way.
Do you do leak detection in Staten Island the same day?
Yes. An active leak causing damage is treated as an emergency, 24/7.
