Slab Leak Detection & Repair

A slab leak is the most expensive plumbing problem you can ignore. We use acoustic listening, pressure testing, and line tracing to narrow the leak location. Locating manifolds helps us plan access and minimize unnecessary drywall damage before recommending repair or rerouting.

  • Warm spots on the floor, running water sounds, or a spiking water bill
  • Foundation-safe access with minimal concrete removal
  • Post-repair pressure verification before we leave

How we diagnose

Acoustic listening, pressure testing, line tracing, and locating manifolds help identify the affected line and plan access without opening walls unnecessarily.

How we fix it

A targeted accessible pipe repair or a planned reroute, followed by pressure testing. We explain required floor or wall openings before work begins.

Why it matters

Why slab leak detection & repair is worth doing right

A leak under your foundation never stays small. Water escaping beneath the slab erodes soil, can shift the foundation, encourages mold, and quietly runs up your water bill. Because the pipe is buried, guessing is expensive — accurate detection matters more here than almost anywhere else in plumbing. Finding the exact spot first means a smaller repair, less demolition, and a fix that actually holds.

How we get it done

  1. 1

    Confirm the leak exists

    We rule out fixtures, irrigation, and other sources, then pressure-test the system to verify a buried line is actually losing water before anyone talks about opening the floor.

  2. 2

    Pinpoint the location

    Acoustic listening helps narrow the leak location, pressure testing identifies the affected supply, and line tracing maps the route. Locating manifolds helps us isolate connected lines and choose access points that minimize unnecessary drywall damage.

  3. 3

    Repair or reroute

    For an isolated break, a targeted repair through a small opening may be best. For a line with a history of failures, rerouting around the slab avoids cutting concrete entirely. We walk you through both options with pricing before work begins.

Signs you need slab leak detection & repair

Confirm a leak before opening the floor

A high bill or damp floor alone does not prove a slab leak. Fixture leaks, irrigation, and other supply problems should be considered too. Pressure testing and leak-location methods help determine whether a buried water line is involved and where access may be needed.

Compare access and rerouting options

A targeted repair may make sense for an isolated break. Rerouting or replacing a section can be worth discussing when access is difficult or the line has a history of failures. The best option depends on pipe condition, layout, and the disruption each approach would cause.

Before we arrive

Note when you first noticed the symptoms and gather recent water bills if available. If you suspect a leak, you may need to shut off the main water supply to limit damage. Only operate an accessible shutoff if it is safe; do not force a stuck valve or enter water near electrical equipment. Call us for guidance while you wait.

Preventing it next time

Investigate unexplained changes in water use early. Have abnormal supply pressure evaluated, and keep a record of previous buried-line repairs to help spot a pattern.

FAQ

Common questions

Does a slab leak always require breaking concrete?

Not always. Depending on the layout, a line may be rerouted rather than accessed through the slab. Diagnosis comes first so the practical options can be compared.

Will homeowners insurance cover a slab leak?

Coverage varies by policy and cause. Ask your insurer about resulting damage, leak access, and pipe repair separately; do not assume they are covered together.

Can a warm floor confirm a hot-water leak?

It is a warning sign, not a diagnosis. Testing is needed to distinguish a leaking hot-water line from other heat or moisture sources.
