Seven signs, and the first one pays for the detection visit by itself:
!Your water bill jumps with no usage change.
The most common first symptom. Homeowners say the same thing: "the water bill creeped up over the months." Then it jumps.
!The sound of running water when every tap is off.
Stand still in the quiet house. Water moving with nothing running means water escaping somewhere.
!Damp or discolored patches on walls or ceilings.
Yellow edges, soft spots, paint bubbling. The leak is behind that patch.
!A musty smell that air freshener doesn't fix.
Mold starts in 24 to 48 hours on wet drywall (EPA). A damp smell is a wet wall.
!A warm spot on a slab floor.
Hot water line leaking under the concrete. Bare feet find it first.
!Your water meter moves with everything shut off.
The two hour test: read the meter, turn everything off, wait two hours, read it again. If it moved, you have a leak. No equipment needed.
!Low water pressure that came on gradually.
A leak upstream steals pressure a little at a time. You adjust to it until someone mentions the shower is weak.
A leak you can't see is still costing you every day. Hidden water leak detection in Hempstead finds it before the bill does. On your bill and in your walls. Catching it early is the entire point of leak detection Hempstead NY.
Why Hidden Leaks Are Common in Hempstead Village
More than half of the village's housing stock was built before 1960 (U.S. Census Bureau, ACS 2024; the median home went up in 1958), and the pipes are the same age. Galvanized supply lines rust from the inside and develop pinholes that multiply. A seventy year old line is at the end of its life. Copper isn't immune either: pinholes from water chemistry show up in aging copper across the village.
Slab on grade sections and finished basements hide leaks until the damage spreads. You don't see the wet concrete under the carpet. You see the bill, or the smell, or the stain months later.
The seasonal pattern matters here. February freezes crack old joints; March thaw reveals the damage. The thaw week is when leak detection Hempstead NY calls peak in this village.
Two family homes add another wrinkle: one meter, two households, and nobody sure whose usage jumped. When the bill spikes in a two family, the first question is the tenant's shower. The second question is the pipe in the wall. The meter test settles the first. Our test settles the second.
And the ownership line, because it affects your bill: the Village Code puts the water service line from the curb stop to the meter on the owner. A leak on your side of the curb stop is your water bill until it's found. The longer it runs, the more you pay the water department for water you never used.

The system gets isolated.
Shutoff by shutoff, the search narrows: supply side, drain side, or the service line from the curb.
Non invasive locate.
Hempstead acoustic leak detection starts with listening for the hiss of escaping water, like a stethoscope for your pipes. Thermal imaging finds temperature differences in walls and floors. Tracer gas leak detection on Long Island finds the stubborn ones: harmless gas goes in the line, and the detector sniffs where it escapes. Moisture meters map how far the water has spread.
The spot gets marked and you see the evidence.
The pinpoint, the readings, the thermal image. Then one small access cut, typically about 8 by 8 inches. Not a demolished wall. Not exploratory holes in three rooms.

What a Month of Waiting Actually Costs
Homeowners ask why a diagnostic visit is worth paying for when the leak has not flooded anything yet. Run the leak math. A crack just 1/8 of an inch wide leaks 250 or more gallons a day. Over a month that is roughly 7,500 gallons you paid the water department for and never used, and that is the small bill.
The bigger bill is what the water does on its way out. Wet drywall grows mold in 24 to 48 hours. A slow leak behind a bathroom wall quietly rots framing, swells flooring, and turns a one section repair into a contractor project. Water damage claims average about $15,400 for a reason: the damage, not the pipe, is what costs money.
That is the real comparison. Detection at $150 to $400, quoted in writing, against another month of meter spin plus damage spreading where you cannot see it. Finding the leak early is not the expensive option. It is the cheap one, and the written report with photos is what makes the insurance conversation go your way if the leak already left a mark. Worth knowing for slab leaks specifically: insurance usually splits the bill three ways. Breaking the concrete to reach the pipe is typically covered as tear-out. The water damage to your floors and walls is typically covered as ensuing loss. The pipe repair itself is usually on you. That is why our invoice itemizes detection, access, and pipe repair as separate lines instead of one lump sum.
Spot Repair or Repipe
Leak detection Hempstead NY tells you where. This section tells you what the finding means.
One pinhole in accessible copper: repair the section. That's a normal fix.
Pinholes that keep appearing: copper pinholes multiply, and in our experience most under slab leaks eventually lead to a repipe. About tunneling: you will read online about digging a tunnel under the slab from outside. In Texas that works. Here it rarely does. Our frost footings run 36 to 42 inches deep, and Long Island sand caves into any horizontal hole you try to dig under a slab. An overhead reroute does the same job, no floor damage, at a fraction of the cost. Chasing them one at a time is the expensive option.
Galvanized at the end of its life: replacement beats chasing leaks one by one. Every repair disturbs the next section.
You get the risk explained, the pipe condition shown, and the decision is yours. The full breakdown lives on our repiping page. If the leak turns out to be a burst section, our burst pipe repair team handles the urgent version, and a straightforward plumbing leak repair in Hempstead Village is on the pipe repair page.
What to Do Right Now
Do the two hour meter test tonight. Turn everything off, read the meter, wait two hours, read it again. If it moved, you have a leak. That's free information.
Shortcut for slab leaks: most Village meters have a small leak triangle or star wheel under the lid. Turn everything off, then watch it. If that little triangle is spinning with every fixture shut, water is escaping somewhere. Now close the main house-side valve next to the meter. Triangle stops: the leak is inside your house or under the slab, call us. Still spinning: the problem is at the meter or the street side. Two minutes, no tools.
If water is actively spreading, shut the main and call. Don't wait for the test.
Take timestamped photos for your adjuster before anything gets moved. Wide shots and close ups. The documentation starts with you.
Don't start cutting drywall yourself. Every wrong hole is a repair you pay for twice: once for the hole, once for the patch. Let leak detection Hempstead NY make the one right hole instead.
What Your Neighbors Say
Rated 5.0 by your Hempstead neighbors.
Our water bill jumped and we had no clue why. They found the leak behind the bathroom wall with their camera gear. One small cut, done by dinner.
Two other companies wanted to open up half the ceiling. These guys pinpointed it to one spot. That saved us a fortune in drywall.
They checked the meter first and told me straight it might just be the toilet running. It was not, they found a slab leak, but I trusted them after that.
Thermal camera found the hot line leak under the kitchen floor in twenty minutes. The written report went to my insurance and the claim went through clean.
Recent Work in Hempstead Village
The Kitchen Floor That Felt Warm
A 1960s ranch with a slab on grade kitchen. The owners noticed a warm patch on the tile and a water bill that had crept up two months running. No stain, no puddle, nothing to point at. The two hour meter test moved, so water was escaping somewhere under the concrete.
Thermal imaging found the hot spot within one square of tile, and the acoustic gear confirmed the hiss under it. The detection was quoted in writing first, inside the $400 to $800 slab range. One access point through the slab, the failed hot water section cut out, and the line rerouted overhead so the kitchen floor never has to open again. The written report with photos went to the owners the same day, ready for their insurance file.
A hot line leaking under a slab does not stay small. Left another month, it would have kept soaking the slab and the subfloor around it. Water damage claims average about $15,400, and this one was caught while the repair was still one access point instead of a gutted kitchen.
The Tenant Got Blamed for a Pinhole
A two family home on one meter. The bill jumped and the landlord assumed the new tenant was running long showers. The tenant said otherwise, and the meter test settled it: the dial moved with every tap in both units shut off. Water was leaving through a pipe, not a showerhead.
Isolation testing narrowed it to the supply side, and acoustic listening pinned the leak to a pinhole in a copper run inside the shared bathroom wall. The visit was quoted in writing inside the $150 to $400 range before any work started. One 8 by 8 opening, the bad section replaced, pressure verified, and the wall patched the same visit.
The landlord had been quoted exploratory demolition in two rooms by another company. Instead there was one small cut and a documented cause for the high bill, which ended the argument with the tenant and stopped weeks of water running inside a wall, where mold starts in 24 to 48 hours.
