Know what to look for

Common signs of a hidden plumbing leak

Leaks can travel along framing, pipes, cabinets, and flooring before becoming visible. The wet spot is not always directly below the source.

  • Water stains that grow or return
  • Damp cabinets, walls, flooring, or baseboards
  • The sound of running or dripping water with fixtures off
  • Unexpected water use or a meter that continues moving
  • Musty odors near plumbing walls or wet materials
  • Low pressure or recurring wet areas without an obvious source
What to do now

A hidden leak usually leaves clues.

The goal is to describe the evidence clearly: where moisture appears, when it changes, and whether the leak is active right now.

  1. 01

    If water is actively spreading, shut off the affected fixture or main supply when it is safe to do so.

  2. 02

    Photograph visible stains, bubbling paint, wet flooring, or meter readings that may help document the problem.

  3. 03

    Avoid opening walls or ceilings when electrical wiring or other hazards may be present.

Frequently asked questions

Leak Detection questions

General answers before you choose a local service page.

How do I know whether I have a hidden water leak?

Recurring stains, unexplained dampness, running-water sounds, unexpected water use, and moisture that appears when a fixture runs are common clues.

Can the visible wet spot be far from the actual leak?

Yes. Water can travel along pipes, framing, flooring, and other materials before it becomes visible.

Should I open the wall to look for the leak?

Not when you are unsure what is behind the surface. Wiring, pipes, and other hazards may be present, and unnecessary demolition can make the repair larger.

Can a leaking toilet raise my water use?

Yes. Some toilet leaks run continuously without putting water on the floor. Changes in usage and meter movement can help identify the problem.

What should I include in the request?

Describe where moisture appears, when it started, whether it changes when fixtures are used, and whether water is actively spreading.
