In two-family houses and co-op buildings, a leak you can't see can show up as a stain in the apartment below or a water bill that suddenly jumps. Instead of opening walls at random, we locate the leak first with acoustic and thermal equipment, then make a small, targeted repair.
If the source is a fixture, our toilet and faucet repair team fixes it on the same visit. Active leaks into a neighbor's unit get emergency dispatch, which is common in the co-ops of Jackson Heights and Sunnyside.
When to call for leak detection
- Your water bill rose without any change in use
- Brown stains or bubbling paint on ceilings or walls
- You hear water running when nothing is on
- A floor feels warm or damp in one spot
- Musty odors or mold near a bathroom or kitchen
What happens on the visit
- Pinpoint the leak without tearing into walls.
- Show you where it is and what the repair involves.
- Flat price, then a clean repair through a small opening.
- Pressure-test to confirm the leak is gone.
How is leak detection priced?
You get one flat, written price after we diagnose the problem. These factors have the biggest effect on it:
- Detection method — acoustic, thermal or pressure testing
- Location: behind tile, under a floor or in a shared riser
- How much finish has to be opened and restored
- Whether multiple leaks or failing pipe sections turn up
Tips to avoid the next repair
- Read the water meter with everything off — movement means a leak
- Replace sink and toilet supply lines every 5–8 years
- Re-caulk tubs and showers when caulk cracks
- Keep an eye on ceilings below bathrooms

Leak Detection FAQ
Do you have to break the tile?
Only where the leak is. Locating it first keeps the opening as small as possible.
Can you help with a leak coming from the upstairs unit?
Yes. We trace it to its source and can write up what we found for the owner, board or insurer.
Do you fix radiator pipe leaks?
Yes — see our boiler repair service for heating pipes and valves.
