- A spike in your water bill without added usage
- Water stains or bubbling paint
- Low water pressure throughout your home
- Musty odors or a mildew smell in one area

Our Advanced Leak Detection Methods
At Lynch Plumbing, we use cutting-edge technology to locate every pipe leak with precision, from dripping faucets to major underground leaks like sewer leaks. We provide advanced leak detection services for all property types throughout the San Fernando Valley, Los Angeles County, and Ventura County.
Infrared Cameras
We use infrared thermal imaging to detect differences in temperature caused by moisture behind walls or under floors. This method is fast and ideal for initial assessments.
Benefit: Rapid identification with no property disruption.
Acoustic Leak Detection
Highly sensitive microphones listen for the sound of escaping water inside your plumbing. The loudest signal marks the location of the leak.
Benefit: Accurate pinpointing of the leak for faster leak repair.
Gas Tracer Technology
We inject a non-toxic gas blend into the pipeline. A sensor then detects where the gas escapes, revealing the exact leak location—even in noisy or hard-to-access areas.
Benefit: Reliable detection with minimal digging or damage.
Preventing Water Damage From Leaks
Having your plumbing checked regularly and getting water leak repair early on is important to preventing future plumbing issues and water damage.
Delaying leak repair services can cause:
- Mold growth
- Rotting drywall or framing
- Foundation cracks from slab leaks
- Insurance claims denied due to negligence
- Higher home repair costs down the line
Routine inspections from a San Fernando plumber are especially important in older homes and commercial buildings. A small leak can easily turn into thousands of dollars in property damage if left unchecked.


Residential vs. Commercial Leak Detection
We provide leak detection services for homes, retail shops, apartments, HOAs, offices, and industrial sites across Los Angeles and Ventura County.
Our team adapts leak detection and repair methods to suit the setting.
Examples include:
- Slab leak detection without breaking flooring
- Tracing drain lines in apartment complexes
- Quiet emergency leak detection in busy office buildings
- Safe, non-invasive service for residential properties
A good San Fernando plumber should understand the structure and materials of your space. Our team has this expertise and uses specialized techniques for each job, from a leaky faucet at home to a leaky toilet in a commercial restroom.

If You Suspect a Leak, Quick Repairs Prevent Serious Damage
Delaying action on a water leak can result in major structural problems, health hazards, and high repair costs. A leak behind your walls, beneath your slab, or along your drain lines can cause extensive property damage. The longer it goes unaddressed, the more expensive the outcome is likely to be.
Over time, unchecked leaks can lead to:
- Burst pipes and indoor flooding
- Mold and mildew affecting air quality (and potentially your health)
- Foundation damage caused by slab leaks
- Unsanitary conditions from sewer leaks
- Thousands of gallons of wasted water and rising water bills
If you suspect you might have a leak somewhere in your home or business plumbing, contact us immediately for emergency services. Our San Fernando plumbers respond quickly to prevent damage, reduce repair costs, and restore your plumbing.
