Water leaks can damage drywall, flooring, cabinets and framing long before the source becomes obvious. ONG Plumbing & Heating provides professional leak detection and plumbing repair for homes and small businesses in Bethlehem, Allentown, Easton and surrounding Lehigh Valley communities.
Whether you notice a dripping fixture, a wet ceiling, a sudden increase in water use or moisture around a pipe, we can trace the problem and recommend the right repair.
Finding the source early can reduce the risk of mold, structural damage and expensive restoration work.
We start by identifying where the water is coming from and whether the problem is isolated to a fixture, fitting or section of piping. Once the cause is confirmed, we explain the repair options before work begins.
For active leaks, shut off the nearest fixture valve or the main water supply if it can be done safely, then contact us for service.
Plumbing leaks can begin at fixtures, valves, fittings, appliance connections, water heaters, or sections of supply piping. Some are obvious, such as water dripping under a sink. Others remain hidden until you notice a stain on the ceiling, a damp cabinet, warped flooring, or an unexplained increase in water use.
We inspect the symptoms and the surrounding plumbing before recommending a repair. A stain below a bathroom does not always mean the pipe directly above it is leaking; water can travel along framing or piping before it becomes visible. Careful diagnosis helps avoid unnecessary demolition and replacement of parts that are not actually failing.
Common residential leak sources include shutoff valves, faucet connections, toilet supply lines, water heater connections, pipe joints, exposed copper or PEX piping, and drain fittings. If the leak is connected to a bathroom fixture, our shower and bathtub plumbing service may also be relevant.
Not every leak produces a visible puddle. Warning signs can include bubbling paint, darkened drywall, recurring musty odors, damp flooring, reduced water pressure, or the sound of water moving when no fixture is in use. A water meter that continues to move when all fixtures are off can also suggest that water is escaping somewhere in the plumbing system.
Hidden leaks deserve attention because even a small amount of water can damage drywall, insulation, flooring, cabinets, and framing over time. Moisture can also create conditions that support mold growth. The goal is to find and stop the plumbing source before restoration work begins.
If water is actively spreading, shut off the nearest fixture valve or the main water supply if you can do so safely. For urgent problems, see our emergency plumbing page.
The correct repair depends on what failed. A leaking shutoff valve may need replacement. A loose or damaged fitting may require a new section of piping. A fixture connection may need to be rebuilt, while an older section of pipe may be better replaced than repeatedly patched.
We explain the condition we find and the practical repair options before work begins. When access through a wall or ceiling is necessary, we try to keep the opening limited to the area needed to reach the plumbing. Plumbing repair and finish restoration are separate scopes, so drywall, paint, tile, cabinetry, or flooring repair may require another trade depending on the project.
For underground or exterior pipe problems that cannot be reached from inside, our plumbing excavation service may be appropriate.
Routine attention to visible plumbing can prevent many larger problems. Check under sinks periodically, look around toilets and water heaters for moisture, and pay attention to valves that are corroded or difficult to operate. Older flexible supply lines, damaged shutoff valves, and heavily corroded fittings should not be ignored simply because they are not leaking today.
Water pressure also matters. Excessively high pressure can put unnecessary stress on fixtures, valves, and appliance connections. If you notice frequent leaks throughout the house or pressure that seems unusually strong, the overall plumbing pressure may need evaluation.
Homeowners in Bethlehem, Allentown, Easton, and nearby Lehigh Valley communities can request a plumbing quote if they are seeing signs of a leak or want a problem evaluated before it gets worse.
Can you find a leak behind a wall?
We can evaluate the plumbing and visible symptoms to narrow the likely source. The amount of access needed depends on the location and type of leak.
Should I shut off my water before you arrive?
If there is an active leak causing damage and you can safely reach the appropriate valve, shutting off the fixture or main supply can help limit additional water damage.
Do you repair leaking valves and supply lines?
Yes. These are common plumbing repairs.
Does a ceiling stain always mean a pipe is leaking?
No. The source can be plumbing, a fixture, drainage, or another building component. Diagnosis is important before repairs begin.
