Expert Leak Detection and Water Leak Repair in Los Gatos, CA

Understanding Hidden Plumbing Leaks in Los Gatos Homes

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 supply lines, drain pipes, slab foundations, behind walls, or underground in your yard. Some leaks are immediately visible, like a dripping faucet or a pooling puddle under a sink. But the most dangerous leaks are the ones you can’t see.

Hidden water leaks can silently waste thousands of gallons of water each year. According to the EPA, the average household leak can waste nearly 10,000 gallons of water annually. In Los Gatos, where many homes were built in the mid-20th century or earlier, aging copper pipes, galvanized steel lines, and shifting soil conditions make hidden leaks especially common. Left unaddressed, even a small leak can lead to mold growth, structural damage, foundation cracks, and skyrocketing water bills.

Pro Tip: Check your water meter when all fixtures are off. If the dial is still moving, you likely have a hidden leak somewhere in your system. This simple test takes less than five minutes and can save you thousands in water damage repairs.

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 Santa Clara, every drop counts toward conserving our precious water resources.

Signs You May Have a Water Leak in Your Los Gatos Property

Catching a water leak early is the key to avoiding costly damage. Here are the most common warning signs Los Gatos homeowners should watch for:

Unexplained Water Bill Increases

If your usage habits haven’t changed but your bill has jumped, a hidden leak is a likely culprit.

Low Water Pressure

A sudden drop in water pressure throughout your home can signal a break or leak in your main water line.

Water Stains on Walls, Ceilings, or Floors

Discoloration, bubbling paint, or warped drywall often means water is traveling through your home’s structure.

Mold or Mildew Growth

Persistent moisture from a hidden leak creates the perfect environment for mold, which poses serious health risks.

Musty or Damp Odors

A persistent musty smell, especially in bathrooms, under sinks, or in crawl spaces, often points to a slow, hidden leak.

Foundation Cracks or Shifting

Prolonged slab leaks can erode soil and compromise your home’s structural integrity.

Sound of Running Water

Hearing water moving through walls or floors when no fixtures are in use is a red flag.

Water Meter Activity

Turn off all water-using appliances and fixtures, then check your water meter. If the meter continues to register water usage, you have a leak somewhere in your system.

Pooling Water in Yard

Unusually green grass or waterlogged soil in one area of your yard may indicate an underground pipe or irrigation leak.

 

Pro Tip: Mold can begin growing within 24–48 hours of water exposure. If you notice a musty smell in any room, don’t wait — call Drain & Water at (408) 564-0580 for immediate leak detection.

Our Leak Repair Services in Los Gatos, CA

Once we’ve identified the source and location of your leak, Drain & Water provides comprehensive repair solutions tailored to your property and situation:

Slab Leak Repair

We specialize in detecting and repairing leaks beneath concrete slab foundations using minimally invasive techniques that protect your home’s structure and flooring. Learn more about slab leak services

Trenchless Repair Options

For certain applications, we can utilize trenchless technologies that minimize excavation and preserve your landscaping and hardscaping. 

Pipe Relining (CIPP)

Our cured-in-place pipe lining creates a new pipe within your existing pipe, sealing leaks and extending the life of your plumbing without excavation. Learn about CIPP pipe lining.

Pipe Bursting

For severely damaged or collapsed pipes, pipe bursting allows us to replace old pipes with new ones using minimal digging. See pipe bursting details

Water Line Replacement

From pinhole leaks in copper pipes to full water line replacements, we restore your water supply using trenchless methods whenever possible. Explore water line services.

Emergency Leak Repair

Emergency Leak Repair is available 24/7 for urgent situations. When a pipe bursts or a major leak threatens your home, our rapid response team arrives quickly to stop the water flow, minimize damage, and implement temporary or permanent repairs.

Pro Tip: If you suspect a slab leak, don’t delay. Water pooling beneath your foundation can cause soil erosion and structural settling that becomes exponentially more expensive to repair over time. Call (408) 564-0580 immediately.

  2. Describe Your Concern — Tell us what you’re experiencing — high water bills, wet spots, sounds of running water, or anything else that seems off.
  3. Schedule Your Appointment — We’ll set up a convenient time to visit your Los Gatos home. Same-day and emergency appointments are available.
  4. Get a Thorough Inspection — Our licensed technicians arrive fully equipped with advanced detection tools to locate the source of your leak.

Common Leak Detection Technologies Used in Los Gatos Homes

Modern leak detection has come a long way from the days of guesswork and excavation. At Drain & Water, we use a combination of advanced technologies to locate leaks with pinpoint accuracy — all while keeping your property intact. 

Video Camera Pipe Inspection

A high-definition camera is fed through your plumbing system to visually identify cracks, corrosion, root intrusion, and active leaks inside drain and sewer lines. This is one of our core diagnostic tools and is offered as a free inspection for homeowners.

Electronic Leak Detection

Sensitive acoustic equipment amplifies the sound of water escaping from pipes, allowing our technicians to hear leaks hidden underground or behind walls without any demolition. 

Thermal Imaging

Infrared cameras detect temperature variations caused by moisture, revealing hidden leaks behind drywall, under flooring, and in ceilings that are invisible to the naked eye.

Slab Leak Diagnostics

For homes built on concrete slab foundations — common throughout Los Gatos — we use specialized equipment to detect leaks beneath the slab without breaking through concrete.

Moisture Meters

Handheld moisture detection devices help us confirm the presence and extent of water intrusion in building materials like drywall, wood framing, and flooring.

Pressure Testing

We pressurize sections of your plumbing system to identify weak points and confirm the presence and location of leaks in water supply lines.

Pro Tip: If your Los Gatos home was built before 1970, it likely has galvanized or older copper pipes that are more susceptible to corrosion and pinhole leaks. Proactive leak detection every few years can catch problems before they cause serious damage. Ask us about our repiping services if your pipes are nearing end of life.

Why Choose Drain & Water for Leak Detection and Repair in Los Gatos?

  • Local & Family-Owned — Based in San Jose, we know Los Gatos homes inside and out — from 1800s-era historic properties to contemporary hillside developments.
  • 24/7 Emergency Service — Leaks don’t wait for business hours, and neither do we. Our team is available around the clock for urgent situations.
  • Industry-Leading Warranties — We stand behind our work with limited lifetime warranties on qualifying repairs.

  • Free Video Camera Inspections — We offer complimentary video camera inspections for drain lines to homeowners, giving you a clear picture of what’s happening inside your pipes.

Pro Tip: When hiring a leak detection company, always verify their contractor’s license and ask whether they use non-invasive detection methods. Invasive techniques can cause additional damage and increase your total repair costs. You can verify Drain & Water’s license here.

Frequently Asked Questions About Leak Detection in Los Gatos, CA

How do I know if I have a hidden water leak in my Los Gatos home?
Common indicators include unexplained increases in your water bill, the sound of running water when all fixtures are off, and musty odors or mold growth in areas without obvious moisture. You can also check your water meter — if it’s moving when no water is being used, you likely have a leak. Drain & Water offers professional diagnostic inspections to confirm and locate hidden leaks.

How much does leak detection cost in Los Gatos?
The cost of leak detection varies depending on the complexity of your plumbing system and the suspected location of the leak. Drain & Water provides transparent, upfront pricing before any work begins. We also offer financing through Wisetack to make the process affordable for every homeowner.

Can you detect leaks without tearing up my floors or yard?
Absolutely. Drain & Water specializes in non-invasive leak detection using video camera inspections, electronic acoustic equipment, and thermal imaging. Our exclusive TrenchFree™ technology allows us to locate and repair leaks with minimal disruption to your property — no unnecessary digging or demolition.

How long does a typical leak detection appointment take?
Most leak detection appointments are completed within one to three hours, depending on the size of your property and the complexity of the plumbing system. Slab leak diagnostics or multi-story homes may take slightly longer. Our technicians work efficiently to minimize disruption to your day.

Are slab leaks common in Los Gatos homes?
Yes. Many Los Gatos homes are built on concrete slab foundations with copper water lines running beneath them. Over time, soil shifting, corrosion, and the region’s seismic activity can cause these pipes to develop leaks. Drain & Water has extensive experience with slab leak detection and repair throughout Los Gatos.

What should I do if I suspect a water leak emergency?
Shut off your main water valve immediately to prevent further damage, then call Drain & Water at (408) 564-0580. We offer 24/7 emergency service and can dispatch a technician to your Los Gatos home right away. Acting quickly can save you thousands in water damage restoration costs.
