Slab Leak Detection in Fontana, CA

A warm spot on the floor, the sound of running water when every faucet is off, or a water bill that jumps for no reason can all point to a slab leak, a leak in the water line running under your home’s concrete foundation. Most Fontana homes are built on slabs, and Drain Edge Rooter helps homeowners find and fix these leaks from our shop at 619 E South St in neighboring Rialto.

We are a licensed California C-36 plumbing contractor (#1078977), owned by Isaiah Infante. Our goal is to find the leak precisely so the repair is as small and affordable as possible.

Signs of a slab leak in your Fontana home

  • Warm or hot spots on tile or flooring, often from a hot water line
  • The sound of running water when nothing is on
  • Your water meter keeps moving with all fixtures off
  • Damp carpet, warped wood floors, or mildew smell without an obvious source
  • New cracks in flooring or baseboards that seem damp
  • Low water pressure or a water heater that runs constantly

Quick check: turn off every faucet and appliance, then watch the water meter for 15 minutes. If it moves, call (909) 927-3194.

Why slab leaks happen in Fontana

Fontana grew fast from the 1980s through the 2000s, and many tracts in North Fontana, near Sierra Avenue, and along the Baseline and Citrus corridors have copper supply lines under the slab. Fontana’s hard water slowly wears copper from the inside, and expansive soil moves the slab through wet and dry seasons. Pipes rubbing against concrete or gravel can wear through. Older homes in South Fontana and near the Jurupa Hills may also have galvanized or older copper lines near the end of their life.

How we find and fix slab leaks

  1. Confirm the leak. We isolate hot and cold lines and use pressure testing to confirm there is a leak under the slab.
  2. Pinpoint the spot. Using acoustic listening equipment and line tracing, we locate the leak before anyone breaks concrete.
  3. Choose the repair. Options include a spot repair through a small opening in the slab, or rerouting the line through walls or the attic when the pipe has multiple weak spots. We explain the trade-offs and the price before starting.
  4. Test and restore. We pressure-test the repair and leave the work area clean.

Fontana slab leak FAQ

Will you have to tear up my whole floor?

No. Pinpointing the leak first means any opening is small and targeted. A reroute can avoid breaking concrete altogether.

Is a slab leak an emergency?

A large leak can damage floors and the foundation quickly, so call as soon as you notice signs. If water is visibly spreading, shut off the main valve and see our emergency plumber in Fontana page.

Does homeowners insurance cover slab leaks?

Coverage varies. Many policies cover access and resulting damage but not the pipe itself. We can document what we find to help with your claim.

Many Fontana homes sit on concrete slabs with copper supply lines underneath, and slab leaks are common as that copper ages.
