Plumbing Leak Detection & Repair in NYC

Find and fix plumbing leaks in NYC homes and buildings — pipes, fixtures, valves and leaks into the apartment below. Licensed Master Plumber, upfront pricing.

Leaks in New York City apartments and buildings rarely stay your problem alone — water travels into the unit below, into walls and into ceilings. I&I Plumbing tracks down where the water is really coming from and repairs it at the source instead of patching the symptom.

We repair leaking supply lines, drain pipes, valves and fixtures, and we're experienced with the older piping in pre-war buildings where one fix can expose the next weak spot. You'll know what we found and what it costs before we fix it.

Questions

Water is coming through my ceiling from upstairs — can you help?

Yes. We'll coordinate with the upstairs unit or building management to find the source and repair it. If water is actively pouring, shut off the water to the unit if you can and call us.

Do you open walls to find leaks?

Only as much as needed. We start by tracing the water and testing lines, then open the smallest area required to reach the leak.

Will my landlord or building need to be involved?

For leaks in building pipes or risers, usually yes. We regularly work with supers and property managers to get access and approvals.
