Leak detection and water leak repair across Manhattan
Manhattan leak detection is almost always a leak between apartments, with a managing agent, two owners and sometimes an insurance adjuster waiting for an answer. In co-ops and condos from the Upper East Side to Tribeca we test every fixture in the unit above, the risers and the drains, and deliver a written finding with photos that says whether it is the apartment, a riser or the building. Pre-war buildings on the Upper West Side, in Harlem and in Washington Heights have original brass and galvanized piping that fails in the walls; we find it with pressure testing and thermal imaging and open one access panel.
Manhattan is one bridge or tunnel away from our Greenpoint shop. We know the freight-elevator hours, the certificate-of-insurance paperwork and the alternate-side parking that make or break a Manhattan service call.

Questions from Manhattan
Who finds water leaks near me in Manhattan?
GW Mechanical Corp finds hidden leaks in Manhattan 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 Manhattan 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 Manhattan 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 Manhattan the same day?
Yes. An active leak causing damage is treated as an emergency, 24/7.
