Water Leak Detection Services in Lacey, WA
On the southern tip of Puget Sound, Lacey combines established neighborhoods and commercial properties with lakes, parks, and carefully maintained landscapes. Simply Leak Detection helps Lacey homeowners, businesses, property managers, and plumbers pinpoint hidden water leaks without unnecessary excavation or demolition.
Lacey has a diverse mix of residential properties, and concealed leaks can develop inside walls, beneath slabs, or along buried water lines before the source becomes visible. We combine extensive field experience with acoustic sensors, thermal imaging, tracer gas, and other non-invasive methods selected for the pipe material and conditions.
The city's lawns, gardens, parks, office properties, golf courses, hotels, and retail spaces often depend on extensive irrigation and plumbing systems. We locate leaks in residential and commercial systems accurately so repair work can stay focused and disruption to landscaping, tenants, customers, and daily operations can be minimized.
We also work closely with plumbers and contractors serving Lacey. Every locate ends with documented findings and a clearly marked location, giving the repair team a professional record and a precise place to begin.
A water leak in a managed property has a way of becoming everyone's problem fast - a stained ceiling two floors down, a water shutoff that displaces tenants, and a plumber who needs to open walls before knowing where to look. For property owners and managers in the area, that sequence is expensive and avoidable.
Simply Leak Detection locates the source precisely before anything opens. Whether the loss is in a supply riser, under a slab, or feeding a specific tenant unit, we isolate the system, use non-invasive acoustic and thermal instruments, and deliver findings the same day - with photos and exact coordinates your plumber and insurer can act on immediately.
We work directly with property managers, HOA boards, and building owners across the greater Seattle area. Discreet scheduling, no tenant disruption beyond a brief pressure test, and a written summary of findings included with every invoice make the repair conversation straightforward.
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.

Underground & Irrigation Leak Detection
A buried water line doesn't announce itself. Whether it's the service line running from the meter to your foundation, a mainline crossing the property, or an irrigation zone that hasn't shown up on a bill yet, underground leaks share one inconvenient trait: they run quietly until the damage is visible or the water loss becomes impossible to ignore. Our underground leak detection work covers all of it - from city-side service connections through to the sprinkler manifold at the back of the yard. See our underground leak detection and irrigation leak detection service pages for more detail.
Irrigation and sprinkler systems are among the most commonly overlooked underground leak sources because the affected zones aren't under constant observation. A cracked mainline between the backflow preventer and the valve manifold can run continuously - not just during irrigation cycles - adding thousands of gallons of loss before a water bill flags it. Signs include zones that stay wet between cycles, a controller that cycles normally but loses pressure at the heads, or a meter that keeps moving when everything is supposed to be off.
Underground water pipe leaks are located primarily through acoustics; we typically also use a safe nitrogen/hydrogen tracer-gas blend as additional confirmation of the leak location. We mark the exact leak point, typically within a foot, so the repair is a targeted dig rather than a trench across the lawn. Your landscaping stays intact until the repair contractor needs to open it, and only where they need to.
Slab Leak Detection & Foundation Leak Locating
A slab leak - a break or pinhole failure in a supply or drain line embedded in or running beneath your concrete foundation - is one of the more stressful water problems a homeowner can face. The water often appears far from the source, migrating along the path of least resistance until it surfaces under flooring, at a baseboard, or on the wall opposite the actual pipe. Combining years of experience with high-end equipment including acoustic sensors, thermal cameras, utility locators, and more - we are able to zero in on the exact location of the leak.
Hot-water supply lines are the most common slab leak culprit. They expand and contract with every cycle, and over years that movement creates friction wear against the concrete that eventually opens a pinhole. Post-tension slabs - common in Western Washington construction from the 1980s onward - add complexity because the reinforcing cables have to be respected during any repair planning. We document the position so the repair crew can work from a clear, precise target.
The same non-invasive detection process extends to residential plumbing throughout the home - in-wall supply lines, under-tile hot-water runs, and leaks that present above grade but originate below it. Whether the source is above the slab or beneath it, we locate it without guesswork.
For multi-family properties and HOAs, speed of identification is everything - the longer the source is unknown, the more units, common areas, and building systems are exposed to ongoing water damage. The same precision approach we bring to slab leak detection under a single-family home applies just as directly to a multi-story building with four risers and twelve units.
In both cases, accuracy at the locate stage directly controls the cost of the repair stage. An exact location means one precise opening, one targeted repair, and a written summary of findings included with every invoice that closes the insurance loop cleanly. Guesswork means multiple openings, extended timelines, and conversations nobody wants to have.
Common questions from Lacey customers
Almost certainly, yes. Many water leaks - especially underground supply-line leaks and slab leaks - produce no visible wet spot at the surface, or the water emerges far from the actual break. A water bill that climbs without a change in usage, or a meter that keeps spinning when every fixture is off, are more reliable early indicators than visible moisture.
Turn off every water fixture inside and outside the house, including ice makers, humidifiers, and automatic appliances. Note the meter reading, wait 15–30 minutes without using any water, then check it again. If the meter has moved, water is escaping somewhere in your system. That's a good time to call us.
No. Our detection equipment - acoustic sensors, thermal cameras, and tracer gas probes - works entirely from the surface. We don't cut, core, or excavate anything during the locate. The only thing that gets opened is what your plumber opens to make the repair, and because we've marked the exact spot, that opening is as small as possible.
Every invoice includes a written summary of findings with photos showing the exact location. You take that summary to your plumber, who can schedule and price the repair accurately. We don't do repairs ourselves - which means we have no incentive to overstate the problem or expand the scope.
We provide clear pricing before any work begins - no surprise fees. Detection costs vary based on property type and leak complexity, but the investment is typically a fraction of what a missed or misidentified leak would add to the repair bill. Call us for a specific quote.
