Before you sign
What to ask a New York City contractor first
- 01
Is the detection charge separate from the repair, and does it still apply if no leak is ultimately located?
- 02
How large an opening in floor, wall or slab is expected, because minimising access limits the later restoration work?
- 03
For a slab leak, is a spot repair through the concrete or an overhead reroute proposed, and why that choice?
Before anyone touches a pipe
Verify the licence. It takes two minutes.
- Who licenses the work: New York City Department of Buildings (DOB), the largest of New York's municipal plumbing licensing authorities; New York has no state-level plumbing licence together with the local jurisdiction.
- Who pulls the permit: NYC Department of Buildings (DOB) — the licensed contractor, never the homeowner.
- What to ask for: the licence number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Leak Detection in New York City — common questions
How do I know if I have a hidden leak?
The simplest test: turn off every fixture and appliance that uses water, then watch the water meter's low-flow indicator for 15–20 minutes. Any movement means water is leaving the system somewhere. That test does not tell you where — it tells you that detection is worth paying for.
Is a slab leak an emergency?
It is urgent rather than instantaneous. A slab leak will keep eroding fill under the foundation and driving up the bill for as long as it runs, so it should be located quickly — but you generally have hours to days, not minutes, unless water is entering the living space.
Will detection damage my floor?
Modern detection is designed to avoid that: the point of acoustic, thermal and tracer-gas equipment is to make one small opening instead of several exploratory ones. Ask the contractor what restoration is and is not included before work starts.
Do I need a permit for plumbing work in New York City?
Permits in New York City are issued by NYC Department of Buildings (DOB). As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
Is PlumberNewYork a plumbing company?
No. Independent licensed professionals perform and contract the work directly with you. PlumberNewYork routes the request and links every page to the official New York licence register.
Does PlumberNewYork charge homeowners anything?
No. PlumberNewYork may be compensated by a partner when a homeowner connects with a professional through the site. That never changes what the contractor charges for the job.
Does calling create any obligation to hire?
None. A call or a callback request is a conversation, not a contract. Scope, timing and price are only agreed if you decide to proceed with the professional handling New York City.
Are night and weekend calls handled differently in New York City?
Requests route around the clock, but most contractors price after-hours work differently. Ask for the after-hours rate and a committed arrival window before agreeing to a dispatch.
