A slab leak in Gilbert means a water line under or inside the home's concrete foundation has started leaking. The Town of Gilbert supplies the water, while the plumbing past the meter, including any line buried in the slab, is the owner's responsibility. Call the number on this page to be connected with a local plumber in Gilbert.

What the first visit looks like
Your call is routed to an independent plumber who serves Gilbert. Expect questions about what the meter did with the water off, where the floor felt warm or damp, and whether the problem seems tied to hot water. On site, the plumber usually shuts the house down, isolates the hot and cold sides, and pressure tests each one to prove which line is losing water. Only then do listening equipment and sometimes a thermal camera come out to narrow the spot. You get a recommendation before any concrete is cut.
Cost factors
- How long it takes to isolate and pinpoint the leak
- Whether the fix is a spot repair through the slab or a reroute through walls and attic
- What sits on top of the leak: carpet, tile, wood or a kitchen island
- Pipe material and whether more of the buried line looks worn
- Drying and repair of any wet drywall or cabinetry
- Permit requirements, which the Town's One Stop Shop can answer
Gilbert homes and water
Gilbert is a young town by Valley standards: the median home was built around 2003, and only about 4 percent of houses predate 1980. That doesn't make slab leaks impossible. Buried copper in early-2000s homes can still develop pinholes where it rubs gravel, and plastic lines can fail at a fitting or a spot nicked during construction. The Heritage District and other older pockets can have older plumbing.
Town water is a blend of surface water and groundwater from Town wells, treated with ozone and chlorine. Gilbert's service line inventory reported no known lead or galvanized lines needing replacement. For questions about water at the meter, Public Works is at 480-503-6400; for permit questions, the Development Services One Stop Shop is at 480-503-6700.
Before the plumber arrives
- Find the main shutoff and confirm it closes fully
- Clear access to the water heater, the main shutoff and the meter box
- Note any warm or damp spots with tape so they're easy to show
- Turn off irrigation and any pool autofill so the meter reads only the house
- Pull the last few water bills to show when usage jumped
