Plumber locating an under-slab leak in a Littleton, CO home

Slab-on-grade homes across Littleton, Highlands Ranch and Douglas County sit on expansive clay (bentonite) soils that swell and shrink with moisture, stressing the copper and PEX lines cast into the slab. Combined with hard water, that is a recipe for pinhole leaks — and the sooner we find one, the smaller the repair.

Precise Location, Minimal Demolition

We isolate which line is leaking and pinpoint the spot with acoustic and pressure equipment before touching the slab. Locating the leak precisely is what keeps the repair small — a targeted access point instead of tearing up an entire floor.

Repair, Re-Route, or Re-Pipe

Depending on the pipe’s condition and the leak’s location, we spot-repair the failed section, re-route the line above the slab to bypass the problem, or — when a home has had multiple slab leaks — re-pipe to end the cycle. We explain the trade-offs honestly so you invest once, not repeatedly.

What a Slab Leak Repair Includes

The demolition is the expensive part of a slab leak, so everything we do is aimed at making the access as small as possible. We isolate the failing line, pinpoint the leak under the concrete, and present the honest choice between a spot repair, an above-slab re-route, or a re-pipe if the home has had repeat leaks — then we do the work and restore the area we opened.

  • Pressure isolation to confirm which line is leaking
  • Acoustic and electronic location of the leak under the slab
  • A clear repair recommendation: spot repair, re-route or re-pipe
  • Minimal-demolition access to the failed line
  • Repair, pressure test and restoration of the opened area

Our Slab Leak Process, Step by Step

A slab leak found early is a small repair; ignored, it undermines flooring and the foundation. Our process keeps it small.

  • 1. Confirm — verify the leak with a pressure test and meter check
  • 2. Isolate — determine whether it is the hot or cold line failing
  • 3. Pinpoint — locate the leak precisely so any access is targeted
  • 4. Advise — recommend spot repair, above-slab re-route, or re-pipe
  • 5. Repair & test — fix the line, pressure-test it and restore the floor

  • Licensed & insured, with honest repair-vs-repipe guidance
  • Up-front pricing and 480+ satisfied local customers

What Affects Slab Leak Pricing

Slab leaks vary more than most repairs because the access is the cost. Pinpointing the leak first, and re-routing above the slab where we can, is what keeps the job small; here are the factors that shape your written quote:

  • How accessible the leak is under the slab
  • Spot repair vs. re-route vs. whole re-pipe
  • Flooring type and restoration needs
  • Pipe material and overall condition
  • Extent of any existing water or floor damage
