A mystery water bill in New Hyde Park usually ends at one of two places: a running fixture or a buried leak. We rule out the easy stuff first, toilets, irrigation, the water heater relief valve, then bring out the listening equipment and cameras until the leak has nowhere left to hide. Every Leak & Slab Detection visit ends with evidence: readings, photos, and a marked location, not a shrug and a guess.

Call (833) 834-1087 and describe the symptom: the bill spike, the warm floor spot, the sound of running water, the damp baseboard. We will ask about the meter test and schedule a detection visit. On site we pressure-test zones first to isolate the leaking section, then pinpoint with acoustic and thermal equipment, mark the spot, and quote the repair before anything is opened.

How leak detection works

Wall and ceiling leaks follow different rules from slab leaks. A supply-line leak inside a wall wets drywall from the inside out, so the visible stain sits below the actual breach as water runs down framing. Moisture meters map the wet area’s boundaries, and the wettest reading, not the stain’s center, marks the search zone. Thermal imaging sees the cooled area where evaporation is active. Then a small, surgical opening confirms and exposes the failed fitting or pipe section. The key discipline is opening once, in the right place, which is why we measure before we cut. In New Hyde Park homes with Long Island construction styles, knowing where lines typically run through framing versus slab saves real time.

Signs you need leak detection in New Hyde Park

  • A water meter that moves with everything in the house turned off.
  • Mildew smells or mold growth on a ground-floor wall.
  • Low water pressure that appeared gradually across the house.
  • An outdoor spigot or pool line splits after the first hard freeze.
  • Toilets and tubs drain slowly at the same time.

What’s included

  • Acoustic leak listening with ground microphones
  • Thermal imaging surveys of slabs and walls
  • Pressure testing to isolate the leaking zone
  • Slab leak pinpointing before any concrete is cut
  • Sewer camera inspection where drain leaks are suspected

Long Island: how local conditions affect leak detection

High water table makes leak detection on Long Island a two-question job: is water coming in, or is water getting out? A damp basement corner in a New Hyde Park home can be groundwater seeping through the foundation just as easily as a leaking supply line. The meter test settles it — with all fixtures off, a spinning meter proves pressurized water is escaping the system, while a still meter points to seepage, grading, or drainage problems instead of plumbing.

Freeze-thaw cycles create the Island’s signature hidden leak: micro-splits in copper or PEX fittings that open under pressure and nearly close when the line relaxes, leaking intermittently for months. Pressure testing individual zones catches what visual inspection misses, and acoustic listening picks up the faint hiss of a pinhole that only weeps under full pressure. Intermittent damp spots that never quite dry are the classic symptom. These are the leaks that evade a casual look, and they are exactly why a structured zone-by-zone pressure test belongs in every Island leak investigation.

Where slabs exist — garages, additions, and slab-on-grade sections — thermal imaging earns its keep. A hot-water line leaking under concrete paints a warm plume on the slab surface that the camera reads clearly, while acoustic correlation triangulates cold-line leaks between two sensor points. For New Hyde Park homeowners, pinpointing the leak to a square foot before the saw touches concrete is the difference between a tidy repair and a demolished room. Once located, the repair typically needs only a small, clean opening — one reason Island homeowners are urged to call for detection before they start breaking concrete themselves.

What affects the cost of leak detection in New Hyde Park

Access drives labor on leak repairs more than the pipe itself. A leak under an open garage slab is straightforward; the same leak under a finished kitchen with stone tile means careful removal, protection, and restoration of expensive finishes. Wall leaks behind tile showers or built-ins take similar care. We price the access honestly: the protection, the surgical opening, and the restoration to a paint-ready or tile-ready state. The pipe repair in the middle is often the quickest part of the job.

  • What sits above the leak: flooring type and finishes
  • Protection and dust control during the work
  • Surgical opening size versus exploratory demolition
  • Restoration to finished condition

Common questions

What does leak detection cost?

The detection visit is flat-rate and includes the full investigation plus a written report. The repair is quoted separately once we know what and where the problem is.

Can you detect leaks in walls too?

Yes. Moisture mapping and thermal imaging trace wall and ceiling leaks to their source, and we open surgically once, in the right place.

My water bill doubled but I see no leak. Now what?

Do the meter test: everything off, watch the leak indicator. If it moves, call (833) 834-1087. Hidden leaks show on the bill weeks before they show anywhere else.

What is the warm spot on my floor?

Almost always a hot-water slab leak: escaping hot water warms the concrete above it. Thermal imaging confirms it in minutes.

Why do my drains slow down all at once?

In New Hyde Park homes, several fixtures slowing together usually points to the shared sewer lateral rather than one drain. Roots enter through joints in older clay pipe, and sandy groundwater keeps the soil loose enough for shifts that crack joints further. A camera inspection shows exactly where the intrusion sits.
