Water Leak Detection Services in Shelton, WA
Finding a hidden water leak starts with separating the visible symptom from the place where the water is actually escaping. Our leak detection service in Shelton is designed to locate the problem while leaving finished surfaces intact.
Water leaks don't follow a convenient timeline in Western Washington. A supply line installed decades ago under a concrete slab behaves differently than PEX run through a new subdivision - and neither one announces itself politely. What they share is that the longer they go undetected, the more expensive they become.
Simply Leak Detection has been locating water leaks across the Puget Sound region and Western Washington since 2010. In that time we've located more than 10,000 leaks in homes and commercial properties of every age, construction type, and pipe material - with a 4.9-star rating earned one accurate, non-invasive inspection at a time.
We bring the same equipment and the same standard to every job: acoustic sensors, thermal imaging, tracer gas where needed, and a written summary of findings with photos included with every invoice. No guessing. No oversized repair scope.
Signs you might have a hidden leak
We're most often called in when a plumber has already looked and can't find it - but if you're experiencing any of the following, you don't need to wait that long.
Unexplained spike in your water bill
If your bill jumped without a change in usage habits, water is going somewhere it shouldn't - possibly underground or inside a wall.
Water meter moving when everything is off
Turn off every fixture and appliance, then watch your meter. Any movement - even a slow crawl - confirms water is actively leaving the system somewhere.
Soggy yard patches or zones that stay wet
Sections of lawn or landscaping that are consistently wetter than the rest - especially when the irrigation hasn't recently run - often point to a buried line failure.
Well pump running excessively
If you notice your well pump frequently cycling on (by hearing it, seeing an indicator light, or noticing a high electric bill) when no water is in use, you may have a leak.
Low or inconsistent water pressure
A supply line losing water before it reaches your fixtures will often show up first as pressure that drops or fluctuates for no clear reason.
Sound of running water with nothing on
Hissing, trickling, or rushing water sounds when every tap and appliance is off is a classic indicator of a pressurized leak somewhere in the system.
Warm or hot spots on your floors
A hot-water supply line failing beneath a concrete slab radiates heat upward. Warm patches on tile or hardwood floors are a common early sign of a slab leak.
Wet patches on walls, ceilings, or floors
Moisture that appears without an obvious source - no recent rain, no spill - usually means water is migrating from a hidden pipe failure nearby.
Musty smell, mold, or mildew without a visible cause
Persistent musty odors or mold growth in an area that never gets wet from normal use often traces back to a slow, long-running leak behind or beneath the surface.
Foundation cracks, settling, or uneven floors
Long-running slab leaks erode the soil beneath a foundation. New cracks in concrete or drywall, doors that stick, or floors that feel uneven can all follow from that movement.
Rotten egg or sulfur smell in your house
That distinct sulfur odor is added to natural gas specifically so you'll notice it. A smell near a gas line, appliance, or in your house warrants immediate investigation.
Your plumber said to call a leak detection specialist
Plumbers refer to us when a leak won't reveal itself to standard diagnostics. If yours suggested a specialist, that's exactly what we do.

Underground Water Leak & Sprinkler Line Detection
Underground leaks are a broad category - buried service lines, mainlines, irrigation circuits, and in some cases gas distribution lines running through a property - and they share a common problem: the only way to know exactly where the loss is occurring is with specialized detection equipment. We handle the full range, from locating a single break in a half-inch residential supply line to mapping and testing a multi-zone commercial irrigation system across several acres. See our underground leak detection and irrigation leak detection service pages for more detail.
Commercial irrigation systems - multi-zone controllers, backflow prevention assemblies, and valve manifolds - operate under enough pressure that a single failed valve or cracked mainline can waste thousands of gallons before anyone notices. Property managers, HOAs, and landscaping contractors call us when a zone stops performing, a meter shows unexplained loss, or an irrigation contractor has traced the problem as far as their own equipment can reach. For properties without existing as-builts, we map the line first, then locate the leak - delivering a marked repair point and a written summary of findings included with every invoice that your contractor can work from directly.
Residential sprinkler systems get the same treatment. If it runs underground and it's losing water, we can find where - without turning your yard into a trench to do it.
Leak Detection Inside the Home
Leaks inside the home are often the most disruptive to find - not because the water is hard to detect once damage appears, but because knowing where it originated without opening walls is the challenge. A wet spot on a ceiling could be a supply line in the wall above, a slow drain connection, or condensation from an HVAC line. Our residential leak detection service is built to pinpoint the source before anything gets cut open.
We use acoustic listening equipment and thermal imaging to trace active leaks inside walls, under flooring, and in ceilings without exploratory demolition. The result is a precise location - not a square-foot target area - so the plumber making the repair knows exactly where to open and nothing else gets disturbed.
If the source turns out to be under the foundation rather than inside the wall, the approach shifts to slab leak detection - but the goal is the same: one location, one repair, one written summary of findings. Both services can often be confirmed or ruled out in a single visit.
Commercial properties face a particular challenge: a leak that's a shared concern often becomes no one's priority until damage spreads to a second tenant or a second floor. Our commercial leak detection service is built for exactly that situation - including work on water main leaks serving large-diameter underground lines that feed entire buildings or campuses.
In commercial settings we coordinate around operational hours, schedule in phases when the building requires it, and deliver a written summary of findings with every invoice the same day so the repair can be scoped and approved without delay. The goal is always the smallest necessary disruption and the most accurate possible locate - the two objectives reinforce each other.
Common questions from Shelton customers
Yes. Non-invasive detection is the whole point. We use acoustic sensors, thermal cameras, and tracer gas - none of which require opening walls, shutting off water to occupied units beyond a brief pressure test, or issuing disruption notices to tenants. We schedule around operational hours when needed.
We isolate the building's water system by floor, riser, or tenant zone using valve and pressure tests, then use acoustic and thermal instruments to follow the leak signal to its source. In many cases we can narrow it to the specific floor and line segment on the first visit.
Yes, regularly. We understand that managed properties have different billing, reporting, and scheduling requirements than residential calls, and we accommodate that. We can coordinate with on-site staff, report to property management directly, and schedule in phases when the property requires it.
We try to accommodate urgency - an active, high-volume leak is a different conversation than a slow, monitored loss. Call us with the details and we'll give you a realistic scheduling window. For situations that can't wait, we make every effort to respond the same day.
Our written summary of findings, included with every invoice, documents the leak source and location with photos. Most insurance adjusters and contractors accept it as part of the claim package. In our experience, the summary provides what is needed to establish the source, scope the repair, and support the claim.
