What We Do

How We Locate Slab Leaks

Our slab leak detection process is designed to narrow down the source of a hidden water leak before unnecessary demolition or repairs begin.

01

1. Initial Assessment

We start by reviewing the symptoms, water usage, affected areas, and other signs that may indicate a hidden leak beneath the slab.

  • Review visible signs and symptoms
  • Check water-use and pressure clues
  • Identify likely areas for further testing
02

2. Noninvasive Leak Testing

We use appropriate diagnostic methods to help narrow down the location of a suspected pressurized water leak while minimizing unnecessary access or demolition.

  • Pressure and system testing as appropriate
  • Acoustic and other diagnostic methods when appropriate
  • Targeted testing to narrow down the suspected leak area
03

3. Pinpoint the Suspected Source

Using the testing results, we work to isolate the suspected leak location and determine where access may be needed before repair work begins.

  • Narrow down the suspected leak location
  • Identify the affected plumbing line when possible
  • Reduce unnecessary exploratory demolition
04

4. Findings & Documentation

Once testing is complete, we explain what was found and provide clear documentation of the suspected leak location and relevant findings.

  • Clear explanation of testing results
  • Photos and documentation when applicable
  • Information to help determine appropriate next steps
05

5. Review Repair Options

If a slab leak is identified, we can discuss appropriate repair options based on the location, condition of the plumbing, access, and findings from the inspection.

  • Targeted repair when appropriate
  • Reroute or repipe options when appropriate
  • Clear explanation before repair work begins
06

6. Insurance Claim Documentation

When a slab leak involves a homeowner's insurance claim, clear documentation can help the homeowner and insurance professionals understand the source and findings.

  • Photos and inspection findings
  • Clear leak-detection documentation
  • Communication with insurance professionals when appropriate

Common Questions

Leak Detection FAQ

Answers to common questions about slab leak detection, testing, repairs, and insurance documentation in Corona, CA.

How do I know if I may have a slab leak?

Possible signs include an unexplained increase in your water bill, warm or damp flooring, the sound of running water when fixtures are off, moisture in unexpected areas, or a water meter that continues moving when no water is being used. Professional testing can help determine whether a hidden leak is present and narrow down its source.

Do you only locate leaks, or do you also repair them?

CLDS provides both leak detection and licensed plumbing repair services. If testing identifies a slab leak, we can explain the findings and discuss appropriate repair options based on the location of the leak, access, and condition of the plumbing.

Can you help when homeowner’s insurance is involved?

Yes. When a slab leak involves a homeowner's insurance claim, CLDS can provide relevant leak-detection findings, photos, documentation, and communication with insurance professionals when appropriate. Coverage decisions are made by your insurance carrier.

Can you tell me the cost over the phone?

We can discuss your situation by phone and explain the likely next steps. The exact cost of slab leak detection or repair can depend on the property, access, testing required, location of the suspected leak, and what is found during the inspection.

Can a slab leak be located without tearing up my floor?

In many cases, diagnostic testing can help narrow down the suspected location of a slab leak before demolition begins. The goal is to gather enough information to make any necessary access as targeted as reasonably possible.
