LEAK DETECTION

Find the Source of Unexplained Water

Water stains, damp flooring, a wet yard, or a water meter that keeps moving can point to a plumbing leak. NexGen investigates leaks inside the home and underground outside, narrows down the likely source, and explains what should happen next.

POSSIBLE LEAK SIGNS

What are you noticing?

You do not need to know where the leak started before you call. Tell us what you are seeing, hearing, or noticing, and we will begin by checking the most likely sources.

Inside Your Home

  • Water stains on a ceiling or wall
  • Damp drywall, cabinets, carpet, or flooring
  • Water collecting below a sink, toilet, tub, or appliance
  • A warm spot on the floor
  • A musty odor or moisture that keeps returning
  • The sound of running water when fixtures are off
  • A higher water bill without an obvious reason
  • Water meter movement when no water should be running

Outside Your Home

  • A soggy or muddy area that does not dry
  • Standing water without recent rain
  • Water bubbling up through the soil
  • One area of grass growing faster or appearing greener
  • Soft, sinking, or washed-out ground
  • Water collecting near the foundation or water meter
  • Water moving toward the sidewalk or street
  • A suspected underground water-service-line leak

The place where water becomes visible is not always where the plumbing leak began.

HOW WE INVESTIGATE

We narrow down the source before recommending where to open or repair

Leak detection is a process of following the available evidence. We begin with accessible plumbing and visible conditions before recommending additional testing, access, or excavation.

  1. Start with when and where the water appears

    We ask where the moisture, damage, sound, or unusual water use was first noticed. We also determine whether it is constant or only appears when a specific fixture, appliance, or area is being used.

  2. Check the nearby accessible plumbing

    The technician inspects nearby fixtures, shutoff valves, supply connections, drains, exposed piping, appliance connections, and other accessible plumbing that could be related to the problem.

  3. Separate the possible sources

    When appropriate, fixtures or water sources are checked individually to determine what changes the condition. Meter activity, water-use patterns, visible moisture, pressure concerns, and yard conditions may help narrow down whether the source is inside, concealed, or underground.

  4. Explain what the evidence supports

    We explain what can be confirmed, what the likely source appears to be, and whether repair, additional testing, limited access, or excavation is the practical next step.

Some leaks can be confirmed quickly. Others require additional investigation because the piping is concealed, underground, or affected by more than one possible water source.

TYPES OF LEAKS

Not every plumbing leak reveals itself the same way

Some leaks are visible at the failed connection. Others remain hidden until water reaches a wall, ceiling, floor, cabinet, or area of the yard.

Visible Leaks

A visible leak may come from a faucet connection, toilet supply, shutoff valve, exposed pipe, appliance connection, or another accessible plumbing component. When the source is visible and reachable, diagnosis and repair may be possible during the same visit.

Hidden Leaks

A hidden leak may be located inside a wall, above a ceiling, below flooring, behind a cabinet, or beneath another finished surface. Water can follow framing, piping, gravity, or openings before appearing somewhere else.

Underground Leaks

An underground leak may involve the water-service line or other buried water piping outside the home. The visible wet area may not sit directly above the damaged section because water can move through soil and follow the slope of the property.

The wet spot shows where the water became visible. It does not always identify where the leak started.

WHY THE SOURCE CAN BE HARD TO FIND

Water often travels before you see it

A plumbing leak does not always drip straight down from the failed pipe. Water may follow framing, piping, cabinets, concrete, flooring, or the slope of the soil before it becomes visible. A ceiling stain may begin several feet away. Water below a sink may come from a fixture above. A wet area in the yard may appear downhill from the damaged water line.

Ceiling stains

Water can travel across framing or piping before reaching the ceiling below.

Wet flooring

Moisture may move beneath flooring and appear beyond the room where the leak began.

Cabinet moisture

Water can follow supply lines, drain piping, or the back of a cabinet before collecting at the bottom.

Wet yard conditions

Underground water may follow soft soil, utility trenches, or the natural slope of the property before surfacing.

ACCESS AND TESTING

We do not recommend opening finished surfaces or digging without a reason

The first checks should focus on accessible fixtures, valves, connections, exposed piping, water-use patterns, meter activity, and visible property conditions. Opening a wall, ceiling, floor, cabinet, or section of the yard should only be recommended when the available evidence supports that next step.

We begin with the least invasive checks available

  • Inspect visible moisture and surrounding conditions
  • Check nearby fixtures, valves, connections, and exposed piping
  • Determine whether the issue changes when specific plumbing is used
  • Review meter activity or unusual water-use patterns when appropriate
  • Inspect the visible path of an underground service line and affected yard area

Additional access may be needed when

  • The likely source is behind a finished surface
  • The leak cannot be confirmed from accessible areas
  • The affected piping is below flooring or concrete
  • The suspected water line is underground
  • The repair cannot be completed without reaching the damaged piping

Before recommending an opening or excavation, we explain why the access is needed and what that access is expected to confirm or make reachable.

DETECTION AND REPAIR

Finding the leak and repairing it may be one visit or two

The next step depends on where the leak is located, whether the piping is accessible, and what is required to reach the damaged area.

Visible and accessible leak

When the failed connection or piping can be seen and reached, the technician may be able to confirm the source and offer a repair during the same visit.

Hidden indoor leak

When the likely source is behind a wall, ceiling, cabinet, or floor, limited access or additional testing may be needed before the repair can be completed.

Underground leak

When the suspected leak involves buried water piping, the source may need to be narrowed down before excavation and repair work can be properly planned.

We explain what has been confirmed, what remains uncertain, and what the next recommended step is before additional work begins.

Information that can help us investigate

Questions

Helpful answers before you call

How do I know whether I actually have a plumbing leak?

Possible signs include unexplained moisture, recurring water stains, a musty odor, the sound of running water, unusual meter activity, a higher water bill, or wet yard conditions. An inspection is needed to determine whether plumbing is the likely source.

Why did my water bill suddenly increase?

A higher bill can be caused by increased household use, a running toilet, a leaking fixture, a damaged water line, or another source of water loss. Checking fixtures and meter activity can help narrow down whether a plumbing leak may be involved.

Can you investigate leaks inside walls or below floors?

Yes. The investigation begins with accessible plumbing and visible conditions. When the evidence points to concealed piping, additional testing or limited access may be recommended and explained before work proceeds.

Can you investigate an underground leak in my yard?

Yes. Wet ground, standing water, unusual grass growth, meter activity, or water surfacing near the service-line path may point to an underground plumbing leak. Additional testing or excavation may be needed before the damaged section can be confirmed and repaired.

Can water appear far away from where the leak started?

Yes. Water can follow framing, piping, flooring, concrete, soil, or the slope of the property before becoming visible. The wet area is an important clue, but it does not always identify the exact source.

Will my wall, floor, ceiling, or yard have to be opened?

Not always. Accessible plumbing and visible conditions should be checked first. If the likely source is concealed or underground, additional access may be needed. The reason for that access should be explained before it is recommended.

Can the leak be repaired during the same visit?

Some visible and accessible leaks can be diagnosed and repaired during the same visit. Hidden or underground leaks may require additional testing, access, excavation, or a separate repair scope after the source has been narrowed down.

Should I call NexGen about a non-urgent leak concern?

Yes. Call for non-urgent leak concerns, active flooding, rapidly spreading water, sewage backups, or any condition that may cause property damage. For a possible gas concern, leave the area and follow the emergency safety instructions first.

Tell us where you are seeing the water.

Whether the concern is inside your home or outside in the yard, NexGen will investigate the available evidence, narrow down the likely source, and explain the practical next step.
