Hidden water leaks

Hidden water leaks behind walls & in ceilings, found without the demolition

Stains, bubbling paint, a musty smell or the sound of running water usually mean a leak inside a wall or ceiling. We find the exact location so only a small area needs to be opened.

Short answer: You don't need to open up walls to find a hidden leak. Leak Seekers uses non-invasive equipment to locate leaks inside walls and ceilings, so your plumber opens only the spot that needs repair.

Signs of a leak behind a wall

  • Water stains, discoloration or bubbling paint on walls or ceilings
  • Soft or warped drywall or baseboards
  • A musty smell or new mold and mildew growth
  • The sound of running or dripping water when nothing is on
  • A higher water bill with no change in use

Why it matters

Leaks inside walls and ceilings can run for a long time before anything shows. By then, insulation, framing and drywall may be soaked and mold may already be growing. Locating the exact source quickly limits that damage and the cost of repair.

How we locate leaks inside walls

Depending on the situation, that can include acoustic listening equipment that hears water escaping a pressurized line, thermal imaging that shows temperature changes caused by moisture, moisture meters, line tracing to map where pipes run, and pressure testing to isolate which line is losing water.

Rather than cutting exploratory holes, we narrow the leak down from the outside and mark the location. Your plumber can then open a small, precise area for the repair.

Questions

Questions about leaks behind walls

How do you find a leak behind a wall without opening it?

We use non-invasive detection tools to locate the leak from outside the wall. Depending on the situation, that can include acoustic listening equipment that hears water escaping a pressurized line, thermal imaging that shows temperature changes caused by moisture, moisture meters, line tracing to map where pipes run, and pressure testing to isolate which line is losing water.

Is a ceiling stain always a plumbing leak?

Not always. Ceiling stains can come from plumbing, air-conditioning condensate or the roof. Locating the actual source keeps you from repairing the wrong thing.

Can a leak behind a wall cause mold?

Yes. Ongoing moisture inside walls is a common cause of mold and mildew, which is why it is important to find and fix the leak quickly.
