A slab leak in Alpine is a water line leaking in or under a home's concrete floor. Padre Dam Municipal Water District serves the central-western part of Alpine, and much of the surrounding area relies on private wells or small water systems, but the piping inside the house is the owner's either way. Call the number on this page to be connected with a local plumber in Alpine.

Signs to look for
- On district water, the meter keeps turning when nothing is in use
- On a well, the pump starts or the pressure tank cycles with every tap closed
- A warm or damp area in the floor, often near the water heater
- Flooring that lifts, buckles or feels soft in one spot
- A musty smell in a room with no visible water
- Hot water that runs out sooner than it used to
Rule out a running toilet, a dripping hose bib and irrigation lines before deciding it's the slab.
Alpine conditions
Alpine is an unincorporated East County community, and its water setup is unusual. The County's Alpine Community Plan Update notes that Padre Dam serves only the central-western part of the plan area; about 81 percent of the area by land relies on private wells or small water systems. That changes how a leak is spotted. Homes on district water can use the meter test, while homes on a well have to watch the pump and pressure tank instead. A pump that runs to keep up with a hidden leak also wears faster.
Alpine's median home was built around 1986, and about 38 percent predate 1980. Copper buried in a slab for decades can wear through at rub points, and newer homes can still fail at fittings. Some older houses sit on raised foundations, where a leak shows in the crawl space instead. Higher East County elevations also bring colder winter nights than the coast, which matters more for exposed pipes than for lines under a slab.
What affects cost
- Time to isolate and locate the leak
- Spot repair through the slab versus a reroute above it
- Flooring to open and restore
- Condition of the rest of the buried piping
- On a well, any pump or pressure tank wear from constant running
- Permits, which go through the County for unincorporated areas
