In Fontana, a slab leak is a water supply line leaking under the concrete floor of the house, and the repair is a private job on the owner's side. Water service is split among several providers, with Fontana Water Company the main one, so check your bill for who handles the meter. Call the number on this page to be connected with a local plumber in Fontana.
How the call and first visit go
You are connected with an independent plumber who serves Fontana. On the phone, expect questions about the meter, the location of any warm or wet area, and whether hot water seems affected. On site, the usual sequence is to shut off every fixture, separate the hot and cold systems, and pressure test each. Acoustic listening equipment then narrows the leak, and a thermal camera helps when the hot line is the culprit. Only after the spot is narrowed down does anyone talk about cutting the slab.
What moves the cost
- How quiet the leak is. A small cold-side leak under thick concrete takes longer to find than a hot line that shows on a thermal camera.
- Fix in place or reroute. Opening the floor at one spot versus running new pipe overhead through the attic or walls.
- What is on top. Tile, stone and engineered wood cost more to open and patch than carpet.
- Collateral damage. Soaked drywall, baseboards or cabinets add drying and repair.
- Permit and inspection through the City of Fontana Building & Safety, which takes applications online through Build Fontana or at the counter.
Fontana water and housing
Fontana's median home was built around 1989, per census survey figures via city-stats.com. A lot of the buried pipe is now thirty-plus years old, and older parts of town have some that is older still. Copper fails at rub points and old joints; plastic lines can fail at fittings.
The water provider depends on the address. Fontana Water Company is the main provider, and Cucamonga Valley Water District, West Valley Water District, Marygold Mutual and Crawford Canyon Mutual serve defined areas. The city suggests calling Fontana Water Company first if you are unsure. One practical note from that company: the angle stop and meter valve belong to the water company, so customers should shut water off at their own gate valve instead.
Before the plumber arrives
- Read the meter, wait an hour with no water use, and read it again
- Locate your own gate valve so you can stop the flow if things get worse
- Move rugs and furniture off the warm or damp area
- Photograph any staining or lifted flooring for your files and insurer
