🚨 Signs of a Slab Leak
  • Warm spot on your floor
  • Water sounds with everything off
  • Sudden bill spike
  • Cracked tile or shifting flooring
  • High-usage alert from your water utility

What Is a Slab Leak?

A slab leak is a break or pinhole failure in the water supply or drain lines running beneath your concrete foundation. Hot water lines fail more often — the constant heat stress, combined with soil movement and pipe age, causes copper to thin and crack from the inside.

The water escapes under the slab and either evaporates upward through the concrete (raising your bill) or migrates along the foundation (causing a wet spot to appear on your floor). Because there is no visible pipe above ground, many homeowners don't know they have one until their utility bill doubles.

Why You Shouldn't Wait

Slab leaks erode soil beneath your foundation. That erosion creates voids. Those voids allow your foundation to shift and crack. A slab leak that runs undetected for 6 months causes structural damage that costs far more to repair than the leak itself.

Detection fee applied toward repair when booked same day. Repair pricing quoted after detection — before any concrete is touched.

Meter Test

Shut off all water inside. Go to your meter. If the triangle or dial is turning — that's water leaving the system. Underground or slab leak confirmed.

How We Find Slab Leaks Without Demolition

Acoustic Listening

Electronic amplifiers pick up the sound signature of pressurized water escaping through the crack — through 4–6 inches of concrete. We hear the exact location without breaking a single square foot of floor first.

Thermal Imaging

Hot water escaping beneath the slab creates a temperature differential visible to an infrared camera. We scan your floor and see exactly where the heat signature concentrates — the leak point.

Pressure Isolation

We shut off individual line sections and pressure-test each one. A pressure drop in an isolated section confirms a failure in that specific run — no guesswork about which line is involved.

Tracer Dye

For drain line verification, non-toxic dye introduced into the drain confirms whether the leak is supply-side or drain-side — important distinction for repair method and cost.

Slab Leak Repair Options

After we locate the leak precisely, you get three repair options depending on pipe condition, leak location, and your property.

Targeted Saw-Cut Access

We cut a precise opening above the confirmed leak location — often 12–18 inches — expose the pipe, and repair or replace the failed section. Concrete is then restored. Best for single-point failures in newer pipes.

Pipe Rerouting (Tunneling)

For older pipes with multiple failure risks, tunneling under the slab or rerouting through walls above the slab avoids future concrete access entirely. One-time solution that eliminates recurrence risk.

Epoxy Pipe Lining

A structural epoxy liner is introduced through existing pipe ends, coating the interior and sealing small failures. Non-invasive — no concrete removal. Best for pipes with wall thinning rather than a single catastrophic break.

Slab Leak FAQ

The meter test tells you a leak exists but not where. Slab leaks often show with warm spots on floors, sounds of running water inside, or moisture appearing at floor level. Underground service line leaks (between the meter and your foundation) often show as wet yard patches or no symptoms at all. We determine which during the site visit.
No. We locate the exact point first using acoustic and thermal equipment. The only concrete removed is directly above the confirmed leak — typically a small targeted opening. No exploratory saw cutting.
Many homeowner policies cover the cost of accessing the pipe (concrete cutting, restoration) but not the pipe repair itself. Some cover damage caused by the leak (flooring, subfloor). We provide full documentation — detection report, repair invoice, and photos — for your insurance claim.
A warm spot on the floor is one of the strongest indicators of a hot-water slab leak. Thermal imaging confirms it within minutes of arrival. Other causes (radiant heating, ductwork) are ruled out during the same scan.
