Leak Detection in Everett, WA
Some leaks announce themselves. Others show up only as a water bill that's climbed for no reason you can point to, or a warm patch on the floor, or the sound of running water when every fixture in the house is off. For leak detection in Everett, WA, call (425) 845-0233 and describe what you're noticing. We'll connect you with a local plumber who has the tools to find a hidden leak without tearing the house apart to look for it.
Do this first: the water meter test
Before calling, there's a simple check you can do yourself that tells a plumber a lot. Make sure every fixture in the house is off, no dishwasher, no washing machine, nobody using a faucet, then find your water meter and note the reading, or watch the small leak indicator dial if your meter has one. Wait 30 minutes to an hour without using any water, then check it again.
If the reading has moved, or the leak indicator has spun, water is going somewhere in the system even with nothing turned on. That confirms an actual leak rather than just a high-usage month, and it's useful information to share with the plumber when you call.
Signs of a hidden leak
A water bill that's noticeably higher than a comparable month last year, with no obvious change in household water use, is one of the most common tip-offs. Beyond that, listen and look for the running-water sound when everything's off, a warm spot on an otherwise cool floor (a sign of a hot water line leaking under a slab), unexplained mold or musty smell in one area, or a section of flooring that's warping or discoloring for no visible reason. For more on ruling out other causes of a spike, see our page on why your water bill might be so high.

Slab leaks
A slab leak is a leak in a water line running under a concrete foundation, and it's one of the harder leaks to spot early because there's no visible pipe to check. Hot water line leaks are more common than cold, and often show up first as a warm patch on the floor in one specific area, since the concrete conducts the heat upward. Left alone, a slab leak can undermine the soil beneath the foundation over time and lead to cracking, which is why catching it early matters more than with most other leaks.
Pinpointing a slab leak without cutting into the floor generally means acoustic leak detection (listening equipment that picks up the sound of water escaping under pressure) combined with thermal imaging to spot temperature differences in the floor where hot water is escaping. Together they let a plumber narrow the leak down to a specific spot before any concrete gets cut.
Crawlspace and under-house leaks
A lot of Everett homes, particularly older ones and those on sloped lots, sit on crawlspace foundations rather than slabs, and a leak under the house behaves differently there. Wet or matted insulation, a musty smell coming up through floor registers, or visible standing water when you check the crawlspace access are all signs worth investigating. Western Washington's wet season, roughly October through April, makes this trickier, since crawlspaces naturally take on some moisture from groundwater and rain during that stretch anyway. A plumber can generally tell the difference between seasonal dampness and an actual pipe leak by looking at where the water is concentrated and whether it tracks back to a specific fitting or run of pipe.

How a plumber finds a leak without guessing
Acoustic leak detection is the main tool for locating a pressurized leak in an inaccessible line, whether that's under a slab, in a wall, or buried in the yard. The equipment listens for the specific sound signature water makes escaping a pipe under pressure and helps narrow the search to a small area rather than an entire wall or floor. Thermal imaging adds another layer of information by picking up temperature differences that a hot water leak creates, which is especially useful for slab leaks where the leak itself is hidden.
For an underground leak between the meter and the house, a plumber may also isolate sections of the line and re-test with the meter to narrow down which segment is losing water before digging anywhere.

Common questions
How much does leak detection cost in Everett?
It depends on the plumber, the type of leak, and whether acoustic equipment or thermal imaging is needed to locate it. Ask for a written estimate before the work starts, since the plumber sets the price, not us.
How do I know if I have a slab leak?
Common signs include a warm patch on the floor, a rising water bill with no clear cause, and the sound of running water when everything's off. The water meter test is a good first step, and a plumber can confirm it with acoustic or thermal equipment from there.
Can a leak under the house cause damage even if I don't see water?
Yes. A slab leak can erode soil under the foundation over time, and a crawlspace leak can rot wood framing and grow mold before it's ever visible from inside the house. That's part of why catching a leak early, even a small one, matters.
Will the plumber have to cut into my floor to find the leak?
Not necessarily. Acoustic leak detection and thermal imaging are generally used first to narrow the leak down to a specific area before any concrete or flooring is opened up, which keeps the repair more targeted.
My water bill went up but I can't find any leak, what now?
Run the meter test with every fixture off to confirm whether water is actually moving through the system unused. If it is, a plumber can help locate the source even if there's no visible sign of it yet.
How can I check that the plumber is properly registered?
Washington requires plumbing contractors to be registered with the Department of Labor & Industries and plumbers to hold an L&I plumbing certificate. You're welcome to ask for the registration number and verify it on L&I's Verify a Contractor tool.
