Slab Leak Repair · Orange County & South Bay

There's a leak under your floor. We'll fix it with the least demolition possible.

There are two honest ways to fix a slab leak: open a small area of concrete and repair the pipe, or abandon that section and reroute the line. We quote both, explain the trade-offs, and restore what we open.

What's going on

What we're repairing and why it failed

  1. 01Pinholed copperHard water thins the pipe from within. The hot line goes first because heat accelerates it.
  2. 02Abrasion in the slabPipe cast into concrete rubs with every thermal expansion cycle until it wears through.
  3. 03Stressed jointsSoil movement common in Orange County and the South Bay pulls on rigid connections until one fails.
Honest options

We diagnose first, then you choose

A spot repair is less expensive and keeps the system as designed, but it leaves the rest of the under-slab pipe in place. A reroute abandons that run overhead, costs more up front, and means this section can never leak again. We give you both numbers.

Spot repair under the slab

Best for a first leak with otherwise sound piping. Lower cost, one small opening, restored after.

Overhead reroute

Best for repeat leaks, aging copper, or when the leak sits under flooring you don't want opened.

How a visit goes

From located leak to repaired and pressure-tested

  1. 01

    Confirm the location

    We verify the marked spot before opening anything, so the opening is where the leak is.

  2. 02

    Written scope both ways

    Spot repair and reroute prices, including patching and restoration. You choose.

  3. 03

    Do the repair

    Floors protected and dust contained. Concrete opened only as far as the repair needs, or the new line run overhead.

  4. 04

    Test, patch, verify

    Pressure tested, concrete patched and floor restored to the agreed scope, and we confirm the bill has stopped climbing.

What it costs

You'll see the number before we start

Slab repairs are quoted in writing with restoration spelled out. What drives the price:

  • Depth and location of the leak, and what flooring sits above it.
  • Spot repair versus reroute, which changes both labor and materials.
  • How much patching and floor restoration is included.
  • Pipe material and whether adjacent sections should be replaced while open.
They gave us the choice between repairing under the slab and rerouting, explained both honestly, and did the work exactly as quoted.

FAQ

Questions we get on the phone

For a first leak with sound piping, repairing the spot is usually the better value. If you've had one before, or the copper is old and thin, rerouting overhead ends the problem for that run instead of buying a few years.
