Your Neighborhood Plumbing Experts
At Plumbtree Plumbing & Rooter, we help homeowners locate plumbing leaks accurately and with minimal disruption. Even well-maintained homes can develop hidden leaks over time, especially in older plumbing systems common throughout San Jose.
Professional leak detection takes the guesswork out of the process. If you notice signs like rising water bills, unexplained moisture, or damp areas in your home, a licensed plumber can identify the source and clearly explain what’s happening before damage worsens.
Smart water shut-off systems are increasingly required by insurance providers and help prevent costly damage by automatically stopping water flow when a leak is detected. These systems also send real-time alerts and allow homeowners to remotely shut off water if an issue occurs while they’re away. A professional assessment can determine whether this added protection is the right fit and help reduce the risk of unexpected water damage.

Our Leak Detection Repair Services Offered in San Jose
Leak detection is not one-size-fits-all. The right method depends on where the leak is likely located, how active it is, and what your home’s plumbing system looks like. Our trained experts use a targeted approach designed to reduce unnecessary wall openings and demolition.
Depending on the situation, your leak detection service may include:
- Water meter verification testing to confirm hidden water use
- Fixture and supply line isolation to narrow down the leak zone
- Thermal imaging to identify temperature differences caused by moisture
- Electronic leak detection tools to help pinpoint concealed leaks
- Targeted pressure testing when the leak location is unclear
- Visual moisture evaluation in cabinets, walls, crawl spaces, and around slab edges
If you’re dealing with active damage, we prioritize containment and clear next steps first.
When a Leak Is Suspected, Fast Answers Matter
Leaks do not always show up as obvious standing water. Sometimes it’s a stain, a smell, a rising bill, or a soft spot that doesn’t make sense. When something feels off, the best move is to confirm what’s happening early.
We provide calm, reassuring guidance when:
- A leak is active and causing damage
- Water damage is spreading, but the source isn’t visible
- You suspect a leak and want answers before opening walls
- You need a professional assessment before choosing a repair plan

How We Locate Hidden Leaks in San Jose Homes
We focus on non-invasive diagnostic techniques first. In many cases, a careful process can narrow down the leak location without immediate demolition.
Our typical process includes:
- Locating the water meter and confirming baseline use
- Turning off indoor and outdoor water appliances and fixtures
- Performing water meter leak testing to confirm hidden usage
- Using thermal imaging to identify temperature differences where appropriate
- Using targeted testing to reduce unnecessary wall openings
The goal is accuracy first, not assumptions.
Slab, Foundation, and Underground Leak Detection
Slab leaks and underground water line leaks require careful evaluation. These scenarios are common in established San Jose neighborhoods, particularly in older homes with aging pipe materials.
We provide:
- Identification of slab leaks beneath concrete foundations
- Detection of underground and main water line leaks
- Assessment of soil saturation and risk factors
- Careful evaluation before any repair pathway is discussed
Locating Leaks Inside the Home and Around the Property
Leaks can hide in places homeowners don’t expect, including wall cavities, ceiling runs, crawl spaces, and yard lines.
We help locate:
- Leaks inside walls and ceilings
- Crawl space moisture and under-home leak concerns
- Yard and landscape leak sources
- Connection issues near fixtures or appliances
We focus on accurate location before access, so homeowners avoid unnecessary damage.
Why Older San Jose Homes Are More Vulnerable to Hidden Leaks
Many homes in San Jose were built before 1980, particularly in long-established neighborhoods such as Almaden Valley, Cambrian Park, Willow Glen, the Rose Garden area, and West San Jose. Older construction and aging pipe materials can allow leaks to develop gradually, spread quietly, and go unnoticed until damage appears.
Older homes are more vulnerable because:
- Aging pipe materials are more prone to corrosion and failure
- Older layouts can hide leaks behind walls, under floors, or below slabs
- Small leaks can spread unnoticed until staining, warping, or moisture concerns can develop
- Early detection helps prevent structural and mold-related damage
Signs You May Need Professional Leak Detection
Sudden increase in water bills
This often points to a hidden or underground leak. When the issue is on the hot water side of the system, homeowners may notice higher water and gas bills, and in some cases, warmth in the flooring near the affected area.
Water running when fixtures are off
May signal a main water line or slab leak. You may also hear dripping or water movement when no water is running.
Damp spots, mold smells, or visible water damage
Early signs of concealed leaks.
Reduced water pressure
This can result from leaks within the plumbing system, deteriorating pipes, or pressure-related issues. Excessive water pressure or a failing pressure regulator may also be contributing factors and should be evaluated during the inspection.
Changes in flooring or visible cracking near moisture areas
Possible indicators of long-term slab leaks.
Sewer backup
If backups are occurring alongside moisture or odors, it may indicate a deeper system issue that should be evaluated promptly.
How We Locate Water Leaks Before Any Repair
- Leak detection should never start with opening walls. It should start with precision.
- Precise leak location before repair
- Repairs prioritized over unnecessary pipe replacement
- Clear explanation of findings and options
- No pressure, no assumptions
Affordable Water Leak Detection & Repair You Can Trust
Affordable leak detection is not about shortcuts. It’s about accuracy that prevents costly guesswork.
- Targeted leak detection helps minimize unnecessary demolition by isolating the affected loop rather than the entire system
- In slab leak scenarios, additional evaluation of the looped piping and distribution manifold may be required to identify the source and determine viable reroute options
- Honest recommendations without upselling
- Repairs based on safety and system condition
