What Laguna Hills homeowners say

Our bill doubled and the floor was warm in one spot. They found the slab leak fast, dried the cabinets and tile in place, and set up the reroute. No jackhammering the whole house.

Lorelei P. · Indian Creek · June 2026

Explained every step and showed me the moisture numbers. The slab was actually dry when they finished, not just dry on the surface.

  • Note where the floor feels warm or where flooring has lifted.
  • Check your water meter with everything off to confirm a hidden leak.
  • Shut the main if water is pooling or the bill has spiked.
  • Keep the area clear so we can set leak detection.
  • Call and let our restoration team find the leak and dry the slab.

How it works

How we handle slab leak water damage in Laguna Hills

1

Confirm and locate

We verify the leak with meter and electronic detection and pinpoint it under the slab without opening the whole floor.

2

Stop and extract

We stop the flow, extract any standing water, and protect cabinets and built-ins.

3

Dry the slab

We dry the slab, subfloor, and cabinet bases with mat systems and air movers to a verified reading.

4

Coordinate the fix

We coordinate the repipe or reroute and document everything for your insurance carrier.

A slab leak is a supply line leaking in or under the concrete slab your Laguna Hills home sits on. It rarely floods all at once. Instead it warms the floor, drives up the water bill, and quietly soaks the slab, cabinets, and flooring until it is found.

Why slab leaks are a Saddleback Valley problem

Much of Laguna Hills was built in the 1970s and 1980s on slab-on-grade foundations with copper supply lines. Decades of hard water corrode that copper from the inside, and slab movement stresses the lines, so a pinhole leak under the floor is one of the most common losses we run here.

  • A warm spot on the floor over a hot-water line
  • Running water you can hear with everything shut off
  • A water bill that climbs for no clear reason
  • Flooring that lifts, cups, or loosens

Warm floor or a water bill that jumped? It may be a slab leak. Call and we confirm it and dry the slab. A crew is on-site in 30 to 75 minutes.

Locate precisely, dry thoroughly, save what we can

We confirm the leak with a meter test and pinpoint it with electronic detection, so the repair reaches just the failed section instead of the whole floor. Then our restoration crews dry the slab, subfloor, and cabinet bases with mat systems to a verified reading. The EPA Fix a Leak resources show how a hidden leak adds up, and the University of California ANR resources cover home water use worth reviewing after a repipe.

Test your meter for a hidden leak

Shut off every fixture and appliance, then watch your water meter for 20 minutes. If the dial still moves, water is going somewhere it should not, often into the slab. That simple check has saved our Laguna Hills neighbors thousands.

How do I know if I have a slab leak?

Common signs are a warm spot on the floor, the sound of running water with everything off, a spike in the water bill, or lifting and cupping flooring. A meter test with all water off confirms it.

Do you break up the whole slab?

No. We locate the leak precisely with electronic detection so the plumber can access just the failed section, often with a reroute, rather than jackhammering the entire floor.

Can you save my cabinets and flooring?

Often, if we reach it before the materials sit wet too long. We dry cabinet bases and flooring in place with mat systems where we can, and only remove what cannot be saved.

Why are slab leaks common in Laguna Hills?

Many homes here were built in the 1970s and 1980s on a slab with copper supply lines. Hard water corrodes that copper from the inside over decades, so slab leaks are a common Saddleback Valley loss.

Is a slab leak covered by insurance?

Policies vary. The water damage from a sudden slab leak is often covered even when the pipe repair is not. We document the loss and work with your carrier so you know where you stand.

How long does drying a slab take?

A slab holds moisture, so it often takes several days of monitored drying. We dry to a target reading and confirm with a meter rather than guessing.
