Leak Detection in Brooklyn

Newer construction and converted co-ops along the waterfront and in neighborhoods like Williamsburg and DUMBO bring a different mix — tankless water heaters, PEX repiping, and combi boiler systems that require different diagnostic tools than a century-old steam system. When it comes to leak detection, that context shapes how we approach every job in Brooklyn — from the tools we bring to the diagnostic steps we take first.

Finding a leak in a Brooklyn rowhouse means dealing with party walls and plaster. Pipe runs inside walls shared with the house next door, so water appearing on your side regularly originates on theirs, and establishing which before anyone opens plaster saves a genuinely difficult conversation between neighbours. The other complication is that these houses have several floors of finished space below any given leak, so a slow seep can travel a long way before it surfaces as a stain.

Hidden leaks behind walls, under slabs, or within ceiling cavities are difficult to locate by guesswork alone. We use acoustic listening devices, moisture meters, and thermal imaging to pinpoint the source before recommending any repair. In Brooklyn specifically, we regularly see frozen exposed pipes in uninsulated cellar and garden-level units and original steam boilers approaching or past end of service life, both of which factor into how we diagnose and price leak detection calls in the area.
