Your water bill jumped with no explanation
A sudden spike in your water bill — with no change in usage — is one of the most reliable early signs of a hidden leak. Even a slow drip from a pinhole leak in a supply line can waste thousands of gallons a month.
You hear water running when everything is off
Turn off every tap and appliance in your home. If you can still hear water moving through the walls or floor, or if your water meter is still spinning, you have an active leak somewhere in your system.
Wet spots, staining, or bubbling on walls or ceilings
Water stains that grow, paint that bubbles or peels, or drywall that feels soft to the touch all point to a pipe leaking behind the surface. The visible damage is almost always smaller than the actual wet area behind it.
Musty smell with no visible source
Mold begins growing within 24 to 48 hours of water contact with organic material. A persistent musty smell — especially in a bathroom, kitchen, or basement — often means water has been leaking inside a wall or under a floor long enough for mold to develop.
Low water pressure throughout the house
A sudden drop in water pressure that affects multiple fixtures at once often means a supply line is leaking or has partially burst somewhere between the street and your home.
Warm or wet spots on the floor
A hot water line leaking under a concrete slab or subfloor creates warm patches on the floor surface directly above it. Soft or spongy flooring in a bathroom or kitchen with no obvious spill is a red flag.
A burst pipe — water actively spraying or flooding
Shut off your main water valve immediately. It is typically located in the basement, near the water meter, or under the sink where the main line enters the home. Then call us. This is our top priority call and we respond immediately.
We use professional acoustic listening equipment that picks up the sound of water escaping from pipes through walls, floors, and concrete — without opening anything up first. This is how we pinpoint the exact location of a hidden leak before doing any work, which means we only open the wall or floor exactly where we need to. No exploratory demolition, no unnecessary damage to your home.
Infrared thermal cameras detect temperature differences in walls and floors caused by water movement. Cold water lines running behind drywall create a distinct thermal signature when leaking. This method is especially useful for slow leaks that don't make noise but are quietly damaging the structure around them.
When we suspect a leak in a supply line but can't pinpoint it acoustically, we isolate sections of your plumbing and test pressure drop. A line that loses pressure while isolated is confirmed as the source. This is precise, non-invasive, and conclusive.
A burst pipe is a plumbing emergency. We respond immediately, 24 hours a day. We stop the water, assess the full extent of the damage to the line, and repair or replace the affected section. We work on copper, CPVC, PEX, galvanized steel, and cast iron pipe — whatever your home has, we fix it. A burst pipe at 2 AM doesn't wait for business hours, see our emergency plumbing page for what to do right now.
For confirmed leaks in supply lines, drain lines, or fixture connections, we repair the damaged section directly. Depending on the pipe type, age, and condition, that may mean a section repair, a coupling replacement, or a short segment replacement. We tell you exactly what we found and what needs to be done before we start.
When a pipe has reached the end of its serviceable life — heavily corroded galvanized steel, chronically leaking copper with multiple pinhole leaks, or deteriorated supply lines — a targeted replacement or full repiping is the right solution. We assess whether a section replacement handles the problem or whether the full line needs to be replaced, and we give you an honest recommendation.
A slab leak is a water line leaking beneath a concrete foundation. They are serious — sustained water under a slab erodes soil, weakens the foundation, and can cause significant structural damage over time. Signs include warm spots on the floor, the sound of running water when everything is off, unexplained moisture along baseboards, and high water bills. We locate slab leaks without jackhammering the entire floor — precise electronic detection first, then minimal targeted access to make the repair.
If you smell gas — rotten egg odor, hissing sound near a gas line, dead grass or plants over a buried gas line — leave the building, don't use any electrical switches, and call us and Con Edison from outside. We locate and repair gas line leaks for residential properties in Astoria and Queens. Gas leaks are treated as immediate emergencies with no exceptions. For non-emergency gas line work, repairs, installs, or DOB violations, visit our gas line repair page.

The clearest signs are a water bill that jumped without explanation, the sound of running water when all taps are off, wet or stained walls and ceilings with no obvious source, musty odor in a room, or low water pressure across the house. If your water meter is spinning while everything in your home is off, you have an active leak.
We use electronic acoustic detection equipment and thermal imaging cameras that locate leaks through walls, floors, and concrete without opening anything first. Once we pinpoint the exact location, we make a single targeted access point to make the repair — not exploratory cuts across the room.
We treat burst pipes as emergency calls and respond immediately, 24 hours a day including nights, weekends, and holidays. For most Astoria and western Queens addresses, we can have a licensed plumber on site within 60 minutes.
Professional electronic leak detection in Queens typically runs $200 to $400. In many cases, when we detect the leak and perform the repair in the same visit, the detection cost is folded into the overall repair price. We'll confirm that when we quote you on-site.
The most common causes we see in Astoria and Queens are frozen pipes in winter months, severely corroded galvanized or cast iron pipes that fail under normal pressure, physical damage from construction or renovation work, and water hammer — repeated pressure shocks in the line from fast-closing valves. Old galvanized pipes that have been corroding for decades are by far the most common cause in the housing stock we work in throughout Queens.
A slab leak is a water supply or drain line leaking beneath your home's concrete foundation. It's serious because water under a slab erodes the soil beneath the concrete, weakens the foundation over time, and creates conditions for mold growth inside the slab itself. Left unaddressed, slab leaks cause structural damage that is far more expensive to fix than the plumbing repair. If you suspect one — warm floor, running water sound with everything off, high water bill — call us for a same-day assessment.
Yes — gas line leak detection and repair requires a licensed master plumber and that is what we send. If you smell gas, leave the building immediately, don't use any switches or open flames, and call us and Con Edison from outside. We treat gas calls as immediate emergencies.
