Slab Leak Repair for St. Augustine homes

Galvanized and patchwork piping in older homes, replaced with small, careful wall openings.

A slab leak is a leak in a water line running under or through the concrete foundation. Hot water lines are the most common culprit, because heat and movement wear the pipe where it rubs against concrete.

What we see in St. Augustine

Why slab leak repair in St. Augustine is a little different.

Older foundations, careful work

Older St. Augustine homes may have mixed foundations and older pipe. We choose the least invasive repair for the structure.

Unexplained water bills

A rental with a rising water bill and no visible leak is a classic slab leak case. We find it fast.

Repeated slab leaks

If an older St. Augustine home has had more than one slab leak, the pipes under the floor are likely aging. Rerouting or repiping overhead prevents the next one.

The owner on every job

Marian handles your slab leak repair from the first call to the cleanup. No subcontractors and no call center.

Signs of a slab leak

Warm spots on the floor

A hot water line leaking under tile or wood can make one area noticeably warm.

Water bill jumps

Usage climbs even though your habits haven’t changed.

Sound of running water

Hissing or running water when every fixture is off.

Damp flooring or baseboards

Wet carpet, lifting floors or musty smells near a wall.

Our approach

  1. Confirm & locate

    Meter and pressure tests confirm the leak, then we pinpoint it.

  2. Explain options

    Reroute, spot repair or repipe, explained before any work starts.

  3. Repair

    The fix is completed and the line is pressure-tested.

  4. Document

    Photos and an invoice for your records and your insurance claim, if you file one.
