Our Process For Water Leak Detection
Initial Leak Symptoms Check
We begin by listening to what you are noticing. This may include a dripping sound, wet carpet, warm flooring, ceiling stains, mold smell, pooling water, or a water meter that keeps moving when all fixtures are off. These signs help us decide where to test first and how urgent the leak may be.
Plumbing System Inspection
Next, we inspect accessible plumbing areas such as sinks, toilets, tubs, showers, water heaters, hose bibs, shutoff valves, crawl spaces, and exposed pipes. Many leaks are caused by loose fittings, worn supply lines, cracked drain connections, toilet seals, corroded copper, or aging pipes. If the leak is visible, we can usually identify it quickly.
Pressure And Meter Testing
If the leak is hidden, we may use pressure testing and meter checks to confirm whether the water supply system is losing pressure. This helps separate a pressurized water line leak from a drain leak, fixture leak, irrigation issue, or appliance leak. This step is important because it prevents unnecessary wall or floor openings.
Non-Invasive Leak Location
For leaks behind walls, ceilings, flooring, or concrete slabs, the goal is to narrow the problem area before any repair begins. Depending on the situation, technicians may use moisture detection, sound-based testing, thermal indicators, and controlled fixture testing. The purpose is simple: locate the leak with as little disruption as possible.
Clear Repair Options
Once the leak source is found, we explain what caused it, how serious it is, and what repair options make sense. Some leaks only require a fixture repair or pipe fitting replacement. Others may need wall access, pipe rerouting, slab leak repair, or water-damaged material removal.
If you are searching for San Jose leak detection and plumbing help, our team can inspect the issue, give straightforward pricing, and help protect your property from further water damage.
Cost Of Water Leak Detection In San Jose
Water leak detection in San Jose usually starts around $125 to $250 for a basic inspection when the leak is easy to access, such as under a sink, near a toilet, around a water heater, or at an exposed pipe. If the leak is hidden behind drywall, under flooring, or above a ceiling, most homeowners should expect a range of $250 to $500 because the technician needs more testing time and diagnostic tools.
For slab leak detection, pricing is often higher. A realistic range is $350 to $700, depending on the size of the property, pipe layout, noise conditions, and how hard the leak is to isolate. Emergency after-hours visits can add another $100 to $250 to the bill.
Detection and repair are usually priced separately. For example, finding the leak may cost $225, but fixing a small exposed pipe leak may add $150 to $450. A wall pipe repair can commonly run $400 to $1,200, depending on access and material. Slab leak repairs can be much more expensive if concrete cutting, rerouting, or flooring removal is needed.
The best way to control cost is to call early. A small leak found quickly is usually far cheaper than waiting until drywall, cabinets, subflooring, or foundation areas are damaged.

FAQ'S About Water Leak Detection
How do I know if I have a hidden water leak?
Common signs include high water bills, damp floors, wall stains, mold smell, low water pressure, running meter movement, or water sounds when fixtures are off.
Can a plumber find a leak without opening the wall?
Yes. Many leaks can be narrowed down with moisture testing, pressure testing, meter checks, sound detection, and fixture isolation before opening walls.
How much does water leak detection cost in San Jose?
Most leak detection visits cost about $125 to $500. Slab leak detection can cost $350 to $700 or more depending on complexity.
Is leak detection included with the repair?
Not always. Detection and repair are often separate charges, but some companies may apply part of the diagnostic fee toward the repair.
What causes hidden water leaks?
Common causes include aging pipes, loose fittings, cracked supply lines, slab movement, corrosion, high water pressure, worn seals, and poor installation.
Is a slab leak an emergency?
Yes, it can be. A slab leak can damage flooring, concrete, walls, and foundations if it is not found and repaired quickly.
Why is my water bill high but I see no leak?
The leak may be underground, under the slab, inside a wall, in an irrigation line, or caused by a running toilet or faulty fixture.
Can leak detection find ceiling leaks?
Yes. Ceiling leaks can often be traced to upstairs bathrooms, drain lines, roof-related plumbing penetrations, or supply pipes above the ceiling.
Should I shut off my water before the plumber arrives?
If water is actively leaking or causing damage, shut off the main water valve. If the leak is minor, leave the area visible for inspection.
