Leak Detection in Gilroy
Find & Fix Hidden Water Leaks Fast
Worried about a hidden water leak in your Gilroy home? Drain & Water provides professional leak detection and repair services using advanced, non-invasive technology. Serving Gilroy and South Santa Clara County 24/7.
What Is a Water Leak?
Why Should Gilroy Homeowners Care?
A water leak occurs when water escapes from your plumbing system through cracks, corrosion, loose fittings, or damaged pipe joints. Leaks can happen anywhere — in your water supply lines, beneath your foundation (known as a slab leak), inside walls, or underground in your yard. Even a small, pinhole-sized leak can waste hundreds of gallons of water per month and lead to mold growth, structural weakening, and inflated water bills.
For Gilroy homeowners, water leaks are especially concerning because many homes in the area were built across several decades — from mid-century developments to newer communities like Harvest Park and Eagle Ridge. Older galvanized steel and copper pipes are prone to corrosion over time, while shifting soils in the Santa Clara Valley can stress underground water lines. Recognizing and addressing leaks early is the single most effective way to prevent costly water damage and protect your home’s value.
Pro Tip: If your water meter continues to spin when all fixtures are turned off, you likely have a hidden leak. Check your meter before and after a two-hour window with no water use — any movement confirms a leak somewhere in your system.
Did You Know
A single dripping faucet wasting one drip per second can waste more than 3,000 gallons per year—enough water to take over 180 showers—and in drought-prone Gilroy, every drop counts toward conserving our precious water resources.
Unexplained spike in your water bill
Unexplained increase in your water bill — A sudden spike without a change in usage is one of the most reliable indicators of a hidden leak.
Sound of running water when all fixtures are off
Sound of running water when all fixtures are off — If you hear water flowing through pipes when nothing is in use, a leak is likely present.
Warm or hot spots on your floor
Warm or damp spots on floors — Especially on concrete slab foundations, warm patches may indicate a hot water slab leak beneath your home.
Damp, soft, or discolored spots on walls, ceilings, or floors
Water stains, bubbling paint, or warped flooring often signal a leak behind the surface.
Musty or mildew odors
Mold, mildew, or musty odors — Persistent moisture behind walls or under flooring creates the perfect environment for mold growth.
Unusually lush or soggy patches in your yard
Wet or soggy patches in your yard — Unexplained green patches or standing water in your landscape may signal an underground pipe leak.
Low water pressure
Low water pressure — A leak in your main water line can reduce pressure throughout the house.
Cracks in your foundation or flooring
Prolonged slab leaks can erode the soil beneath your foundation, leading to shifting and cracking.
Warning Signs You May Have a Hidden Water Leak in Your Gilroy Home
Not every leak announces itself with a dramatic burst pipe. Many water leaks are silent and hidden, making early detection critical. Here are the most common signs Gilroy homeowners should watch for.
Pro Tip: Walk your property monthly and look for unusually green or lush patches of grass — this often indicates a leaking underground water or sewer line feeding that area.
If you notice any of these signs, don’t wait. Contact Drain & Water for a professional leak detection assessment before the damage spreads. For more warning signs, read our guide on 7 Early Warning Signs You Might Have a Hidden Leak.
Expert Water Leak Detection Services
Our Leak Repair Services in Gilroy, CA
Once we’ve located your leak, Drain & Water offers a full range of repair solutions tailored to the type and severity of the problem:
Pipe Lining (CIPP)
Cured-in-place pipe lining creates a new pipe inside your existing damaged pipe, sealing leaks and preventing future corrosion without excavation.
Slab Leak Repair
Slab leaks are common in Gilroy homes built on concrete foundations. We use non-invasive techniques to access and repair the leak with minimal disruption to your flooring.
Pipe Bursting
For severely damaged water or sewer lines, pipe bursting replaces the old pipe by pulling a new one through the existing path — no trenching required.
Drain Repair
Leaking drain lines can cause water damage and sewage issues. We repair and replace damaged drain pipes using trenchless and traditional methods.
Repiping
If your Gilroy home has aging galvanized or polybutylene pipes with recurring leaks, a full or partial repipe may be the most cost-effective long-term solution. Learn about PEX vs. copper piping options.
Water Leak Repair
From minor pipe joint repairs to full section replacements, we fix leaks in supply lines, fixtures, and connections throughout your home.

Common Leak Detection Technologies We Use in Gilroy
Modern leak detection goes far beyond guesswork. At Drain & Water, we use a combination of professional-grade technologies to pinpoint leaks accurately and non-invasively:
Acoustic Leak Detection
Sensitive listening devices amplify the sound of water escaping from pressurized pipes, even through concrete slabs and soil. This is one of the most effective methods for locating slab leaks in Gilroy homes.
Electronic Leak Detection
Specialized equipment measures pressure abnormalities and inconsistencies in your pipe system by sending signals through the plumbing. This helps our technicians zero in on the exact location of a breach.
Video Camera Inspection
A waterproof camera is fed through your plumbing lines to provide real-time video of the interior condition of your pipes, identifying cracks, corrosion, root intrusion, and joint failures.
Thermal Imaging
Infrared cameras detect temperature variations behind walls and under floors caused by leaking hot or cold water lines, revealing hidden moisture without any demolition.
Hydrostatic Pressure Testing
We isolate sections of your plumbing system and monitor pressure levels to determine whether a line is holding or losing water, helping narrow down the leak’s location.
Tracer Gas Detection
For particularly elusive leaks, a safe, non-toxic gas is introduced into the pipe. Sensitive detectors at the surface pinpoint exactly where the gas — and the leak — escapes.
Pro Tip: Not all leak detection companies use the same technology. Ask what equipment they’ll bring before scheduling. A company that relies on multiple methods — like Drain & Water — is far more likely to find the leak on the first visit.

Our Leak Detection Process in Gilroy
When you call Drain & Water for leak detection in Gilroy, here’s exactly what happens:
Step 1: Initial Consultation and Symptom Review
We start by listening. Our technician will ask about the symptoms you’ve noticed — high water bills, damp spots, sounds of running water — and review your home’s plumbing history and pipe materials.
Step 2: Visual Inspection
We examine accessible plumbing fixtures, connections, water heater, and visible pipes for obvious signs of leaks, corrosion, or moisture damage.
Step 3: Advanced Diagnostic Testing
Using acoustic sensors, thermal imaging, video camera inspection, and pressure testing, we systematically narrow down the leak’s exact location — whether it’s under your slab, behind a wall, or underground in your yard.
Step 4: Findings Report and Repair Recommendation
We walk you through what we found, show you camera footage when applicable, and provide a transparent repair recommendation with upfront pricing. No surprises.
Step 5: Professional Repair
With your approval, we proceed with the repair using the least invasive method possible — often leveraging our exclusive TrenchFree™ technology to preserve your property.
Step 6: Verification and Cleanup
After the repair, we re-test the system to confirm the leak is fully resolved, clean up the work area, and ensure everything is restored to its original condition.
Pro Tip: Before your technician arrives, locate your main water shut-off valve and your water meter. Knowing where these are speeds up the diagnostic process and can help you stop water flow in an emergency.

Frequently Asked Questions About Leak Detection in Gilroy, CA
How do I know if I have a hidden water leak in my Gilroy home?
The most common indicators include unexplained spikes in your water bill, the sound of running water when all fixtures are off, and damp or warm spots on your floors. If your water meter shows usage when nothing is running, that’s a strong confirmation. Learn more about hidden leak warning signs.
What is a slab leak and are Gilroy homes at risk?
A slab leak occurs when a water line beneath your concrete foundation develops a crack or hole. Many Gilroy homes are built on concrete slab foundations, making them susceptible to slab leaks caused by soil shifting, pipe corrosion, or poor original installation. Early detection is critical to preventing foundation damage.
How long does a professional leak detection service take?
Most residential leak detection inspections in Gilroy take between one and three hours, depending on the complexity of your plumbing system and the location of the leak. Drain & Water uses multiple diagnostic technologies to ensure accuracy, which can sometimes speed up the process significantly.
Will leak detection damage my property or landscaping?
No. Drain & Water uses non-invasive detection methods including acoustic sensors, thermal imaging, and video camera inspections. Our TrenchFree™ technology also allows us to perform many repairs without excavation, preserving your landscaping and hardscaping.
Can a small leak really cause serious damage?
Absolutely. Even a slow drip can waste over 10,000 gallons of water per year and create conditions for mold growth, wood rot, and foundation erosion. In Gilroy’s warm climate, moisture trapped behind walls or under slabs can accelerate mold development, posing health risks to your family.
Do you offer emergency leak detection services in Gilroy?
Yes. Drain & Water provides 24/7 emergency plumbing service. If you discover a burst pipe, active flooding, or a sudden loss of water pressure, call us immediately at (408) 564-0580 and we’ll dispatch a technician as quickly as possible.
What types of pipes are most prone to leaking in older Gilroy homes?
Galvanized steel pipes, commonly found in homes built before the 1970s, are highly prone to internal corrosion and leaks. Polybutylene pipes (used in the 1980s–1990s) are also known for premature failure. If your home has either material, consider a repiping consultation to prevent future leaks.
