A hidden leak can run for weeks before you see it. By then it may have soaked a subfloor, stained a ceiling or raised your water bill. Guessing means opening walls in the wrong place. Leak detection finds the source first, so the repair is smaller.

Signs you need leak detection

Hidden leaks leave clues. You may notice one of these long before you see water.

  • If your use has not changed but the bill has, water may be leaking out of sight.
  • Turn off all taps and appliances. A moving meter dial means water is escaping somewhere.
  • A warm patch on tile or concrete can mean a hot water line is leaking under the slab.
  • Hissing or dripping when nothing is on often means a leak in a wall or floor.
  • Moisture from a leaking line can stain ceilings, lift paint or soften drywall.
  • New cracks or damp areas on a concrete floor can come from a leak in the pipe below.

Our leak detection work

  • Working through a wall access opening behind a shower valve.
  • A wall opened to reach the supply lines and fittings behind it.
  • A small, clean access cut to repair a supply line inside the wall.
  • A tidy access hole to reach a copper line, keeping the wall opening small.
  • A new copper section in an opened wall after a leak repair.

    With everything off, we check the meter to confirm water is escaping.
  2. Scan without damage

    We mark the spot, explain what we found and give you an upfront, flat-rate price for the repair.
  4. Repair or reroute

Hidden Leaks in South Sound Homes

Crawlspaces are common in older South Sound homes, and a slow drip there can go unseen. Lakewood has many mid-century homes, and Federal Way has many from the 1960s to 1980s. A hard freeze can split an exposed pipe and leave a hidden leak behind.

Many homes on South Hill and in Bonney Lake were built from the 1980s onward. Some sit on concrete slabs, where a leak may show up as a warm floor or a high bill, not a puddle. Rain-soaked yards can also hide a buried line leak until the bill arrives.

  • Crawlspaces are common in older homes, where slow leaks go unseen.
  • Cold snaps put crawlspace and exterior-wall pipes at risk of splitting.
  • Wet winter soil can hide a buried line leak.

Common Questions

How do plumbers find a hidden leak in Tacoma without tearing up walls?

Rooter-Man Plumbing of Tacoma uses non-invasive leak detection, including thermal imaging. A thermal camera shows temperature changes where water is soaking a wall or floor. Along with meter checks and listening for the leak, it helps us find the spot. Then we open only what we need.

What is a slab leak, and how do I know if I have one?

A slab leak is a leak in a water pipe under a concrete floor. Signs include a warm spot on the floor, the sound of running water, damp patches or a water bill that jumps. We confirm it with non-invasive tools before any concrete is opened.

Why is my water bill suddenly high in Pierce County?

If your use has not changed, a hidden leak is a common cause. Check toilets for running water first. Then turn off every tap and watch the meter. If it still moves, call us. We find the leak and price the repair before any work begins.

Frequently Asked Questions

Not to find the leak. We use thermal imaging and other non-invasive methods to locate it first. Once we know the spot, the repair may need a small opening to reach the pipe. Your price, given before work begins, explains what will be opened.

Yes. Many leaks can be fixed the same day, with an upfront, flat-rate price first. If your pipes are failing in many places, we may suggest a repipe. If the leak is in the buried line from the meter, we may suggest a water line replacement.

A thermal camera shows temperature, not water itself. Wet areas often read cooler, and a leaking hot water line reads warmer. That pattern helps us trace a leak through drywall, tile or concrete. We pair it with meter checks and other tests.

If you see water spreading or hear a burst pipe, yes. Shut off the main valve and call us. Phones are answered 24/7 by a real person. For a slow leak, leave the water on until we check the meter, since that test needs water in the lines.

It depends on the size of your home and how hidden the leak is. Our $49 diagnostic fee is waived when you approve the repair. After we find the leak, you get an upfront, flat-rate price with parts and labor included, before work begins.

Yes. A leak in the buried water line can show up as a soggy patch, a sinking spot or a high bill with no wet spot at all. We check the meter and trace the line to find the leak. If the line is worn out, we can price a replacement.
