The housing itself shapes the job. Canal-front homes along Highway 106 from 1940s cabins to substantial 1990s and 2000s rebuilds, hillside homes in Union Ridge and Vuecrest from the 1970s onward, and a mix of manufactured and custom homes on the uplands. A high share of second homes and retirees. It is about 50 minutes from Port Orchard, west on Highway 3 to Belfair and then Highway 106 along the South Shore of Hood Canal to Union, a run we make often enough to know the roads, the water districts and the quirks of the housing.
Why leak detection & repair is a little different in Union
Crawlspaces in Union are damp much of the year, which makes condensation on cold water lines look exactly like a leak dripping onto the insulation. We check the meter and the pipe before quoting anything, because insulating a sweating line is a far smaller job than a repair nobody needs.
The ground is the other half of the story. The south shore of the Great Bend, with a narrow shoreline bench, Highway 106 running along it, and steep bluffs and benches rising behind. Thin soil over glacial deposits on the slopes, and a water table at the surface along the shoreline in winter.
Local conditions that affect leak detection & repair in Union
In Union specifically, one issue comes up more than most: Well pressure tanks and switches on upland properties
Waterfront and hillside homes in Union tend to have long, complicated supply runs with more joints and more places to fail. Our pressure-and-listen method works regardless of how the pipe was routed, and it keeps the number of access holes to one.
Ask a Union homeowner what goes wrong with plumbing here and you will usually hear a version of this: Scale on tankless and tank heaters from mineral-rich groundwater
Many Union homes have original copper supply lines that are now old enough to pinhole, especially on the hot side and anywhere the copper touches steel or a grounding clamp. One pinhole is a repair; the second or third within a year is a sign the system is ready for a repipe, and we price both so you can choose.

Signs Union homeowners call us for leak detection & repair
Worth a call
- A ceiling or wall stain that returns after being painted
- The water meter moves with every fixture in the house turned off
- A warm spot on a concrete or tile floor with no radiant heat
- The water heater runs or cycles when nobody is using hot water
- A musty smell in a closet, under a sink or in the crawlspace

Leak Detection & Repair questions from Union
Will you have to cut several holes in my walls?
Our goal is one. We locate the leak before opening anything, and the access cut is sized to the repair. We leave a clean square opening that is easy for a drywall contractor to patch.
Do you handle slab leaks in Union?
Yes. We locate them with hot-side isolation, thermal imaging and listening equipment, then repair through the slab or reroute the line above the floor, whichever makes sense for the house. Both options are priced.
Can you help with my insurance claim for a leak in Union?
We document the leak with photos before and after the repair and describe the cause clearly on the invoice. Many Union customers have used that documentation for claims. We do not handle restoration or drying, but we refer you to companies that do.
My Union crawlspace is wet. Is that a leak?
It might be, but in Mason County it is often groundwater or condensation. We check the meter, inspect the pipes and run the drains to tell the difference, and we recommend a sump pump or drainage fix if the water is coming from the ground.
What is a slab leak and how do you repair one?
A leak in a water line running in or under a concrete floor. We locate it with hot-side isolation, thermal imaging and listening, then either open the slab at that spot for a direct repair or reroute the line above the floor. For homes that have had more than one slab leak, we usually recommend rerouting or repiping the hot side.
Freezing pump houses, iron-stained well water and septic effluent pumps are everyday work for us in Mason County. Union jobs rarely surprise us.
