Water Damage Lake Forest

A rising water bill. A musty smell with no obvious source. A warm spot on the tile floor. These are the moments homeowners call us not because they've found a leak, but because they suspect one and can't find it. That's exactly what leak detection is for.

We use a combination of tools rather than relying on any single method: thermal imaging cameras that reveal temperature differences where water is present behind a surface, moisture meters that measure water content directly in drywall, flooring, and framing, and acoustic detection equipment that listens for the distinct sound of water escaping under pressure through a pinhole or fitting.

The goal is always the same: find the leak's exact location before anyone opens a wall or cuts into a slab. Guessing wrong means unnecessary demolition, more repair cost, and more time with the leak still running.

Signs You May Have a Hidden Leak

  • A water bill that's risen with no change in household usage
  • The water meter still moving with every fixture in the house off
  • A warm or damp spot on flooring with no visible water
  • A musty smell with no obvious source
  • The sound of running water when nothing is turned on

Our Leak Detection Process

  1. 1

    Interview and inspect

    We start by asking what you've noticed — sound, smell, a bill change, a visible spot — since that narrows down where to focus.

  2. 2

    Scan with thermal imaging

    A thermal camera surveys walls, ceilings, and floors for temperature anomalies consistent with moisture.

  3. 3

    Confirm with moisture meters

    Readings confirm whether a thermal anomaly is actually wet, ruling out false positives from sunlight or HVAC ducting.

  4. 4

    Pinpoint with acoustic equipment

    For pressurized lines and suspected slab leaks, acoustic listening narrows the leak to a small, specific area before any opening is made.

When to Call for Leak Detection

Not every situation needs detection equipment — an obvious burst pipe doesn't require a search. But a rising water bill with no explanation, a persistent musty smell, an unexplained warm spot on flooring, or the sound of running water when everything's off are all classic signs of a leak that's hiding, often related to a slab leak or a pinhole leak in aging copper plumbing.

What's Included in Our Leak Detection Services

A leak detection visit is built to find the exact source before anyone opens a wall, not to guess and hope.

  • An interview about what you've noticed — sound, smell, a bill change, a visible spot
  • A full thermal imaging scan of walls, ceilings, and floors
  • Moisture meter confirmation of any thermal anomaly found
  • Acoustic detection for pressurized lines and suspected slab leaks
  • A clear report on the leak's location before any opening is made

What Affects Leak Detection Cost

Detection cost depends on how much of the home needs to be scanned and what equipment the situation calls for. Factors include:

  • Whether the search covers one room or the whole house
  • Whether acoustic detection is needed for a suspected slab leak
  • Access — a leak behind finished walls takes longer to pinpoint than an exposed area
  • Whether detection is a standalone visit or part of an active water damage call

Frequently Asked Questions

Answers to the questions Lake Forest homeowners ask us most about leak detection.

How accurate is thermal imaging for finding leaks?
Very accurate as one part of a combined approach — thermal imaging shows where temperature is different, which we then confirm with moisture meters before assuming it's water. Using thermal imaging alone can produce false positives from sunlight, ducting, or insulation gaps.
Can you find a leak under my slab without breaking up the floor?
In most cases, yes. Acoustic detection can pinpoint a slab leak's location to a small area, so only that section needs to be opened rather than searching blindly.
What if you can't find a leak but I know something's wrong?
That's rare with a combined-method approach, but if readings are inconclusive, we'll say so honestly rather than recommend unnecessary opening of walls or flooring.
Do you charge separately for leak detection?
We'll walk you through the scope and cost before starting. If we're already on-site for a related water damage call, detection is often included as part of finding the source. Ask us about a free inspection to start.
How soon should I schedule leak detection after noticing a rising water bill?
As soon as you notice it. A leak that's been running for a month is more expensive to fix than one caught in the first week, since more water means more time spreading through flooring, framing, or under the slab.

A pipe burst while we were on vacation. I called from out of state and they took over completely — extraction, drying, and the rebuild. Came home to a house that looked untouched.

Our upstairs neighbor's leak came through our condo ceiling. They handled the HOA paperwork and the repair, and were respectful of our home the entire time.
Priya M.

Found mold behind our bathroom wall after a slow leak. They contained it, removed it, and fixed the moisture problem so it wouldn't come back. Very thorough.
