A ceiling stain in the unit below
Water on a ceiling often comes from a pipe, fixture or drain in the unit above. But it can also come from a shared line in between.
Commercial Leak Detection in Orange, CA
A tenant calls about a stain on the ceiling. The unit above says it's dry. The building water bill is up, and nobody can say why. You need the source found, not a guess that opens walls in three units.
We find leaks in apartments, condos and business buildings across Orange. We trace the water back to the unit, the line and the spot, so the right pipe gets fixed and tenants stay in their homes.

Quick answer
How Are Leaks Found in Apartments and Commercial Buildings?
Commercial leak detection finds water leaks in buildings with many units or users, such as apartments, condos, offices and shops. Pros start with the water meter and the building's shut-off valves. They close off zones or units one at a time to narrow the leak down. Then moisture meters, thermal cameras and listening tools pinpoint the leak inside the right wall, ceiling or floor.
Why Leaks in Shared Buildings Are Harder to Trace
In a single home, water usually shows up near its source. In a building with many units, water travels. It runs along pipes, beams and floors, then shows up in a different unit, sometimes a floor below.
That's why we trace the building, not just the stain:
- Is it a supply leak? The meter and shut-off valves tell us if water is leaving the system.
- Which zone or unit? Closing valves one at a time narrows the leak to a section of the building.
- Which line? Shared lines and risers are tested along the path the water could take.
- Where exactly? Moisture, thermal and listening tools find the spot without opening every wall.
Our team is professional and experienced in this kind of work, and we explain each step to the property manager or owner as we go.

Warning signs
Signs of a Leak in Your Building
The building water bill jumps
If use hasn't changed but the bill has, water may be leaking where no one can see it.
The meter moves after hours
If the meter keeps turning when the building is closed or quiet, water is going somewhere.
Wet walls between units
Damp or stained shared walls can point to a pipe running between two units.
Water in hallways, garages or common areas
Water that shows up in a shared space may come from a supply line running above or beside it.
Musty smells or mold in more than one unit
Hidden water can spread across units before anyone sees a drip.

Common causes
What Causes Leaks in Commercial and Multi-Unit Buildings?
01
Shared supply lines and risers
One pipe can serve many units. A leak on that pipe can show up far from where it starts.
02
Worn fittings and connections
Buildings have many joints, valves and fixture connections. Each one is a place that can wear out.
03
High water pressure
Larger buildings often run higher pressure. Too much pressure strains pipes and joints.
04
Aging pipes
Older buildings may still have their first pipes, which can wear thin and leak over time.
05
Fixture and appliance leaks
Toilets, water heaters, washers and dishwashers in one unit can leak into the unit below.
Our process
How We Trace a Leak in Your Building
- 1
We talk with you first
Where is the water showing? Which units are near it? Where are the shut-off valves? This sets the plan.
- 2
We check the meter
With water use stopped where possible, the meter shows if water is leaving the system.
- 3
We narrow it by zone and unit
We close valves one area at a time to find the section of the building that's leaking.
- 4
We pinpoint the leak
Moisture meters map where water has spread. Thermal cameras show wet or warm spots. Listening tools find the sound of water escaping a pipe.
- 5
We keep tenants in mind
We work unit by unit, and only enter the units the search needs. It helps if the manager lets those tenants know ahead of time.
- 6
We mark it and explain the findings
We show you the source, the unit and the pipe. If you want, we can also take care of the repair.
Need to know which unit the leak is coming from? Call (714) 439-5275 or request a commercial leak inspection.
Equipment
Tools for Finding Leaks in Larger Buildings
Meter checks and pressure test gauges
They show if the system or one section of it is losing water.
Moisture meters
They map where water has spread across walls, ceilings and floors.
Thermal imaging cameras
They show wet or warm patterns that point to a hidden leak.
Acoustic listening devices
They pick up the sound of water leaving a pressurized pipe through walls and floors.
Pipe locators
They trace where shared lines run, so we follow the right path.
Why Trace the Source Before Opening Walls?
- Less disruption for tenants. Only the units the search needs are entered, and only the spot over the leak is opened.
- Fix the right pipe in the right unit. No repeat repairs when the real source is somewhere else.
- Protect common areas and other units. Hidden water spreads. Finding it early limits the damage.
- Clear answers for everyone. Owners, managers and tenants can see where the water came from.

FAQs
Commercial and Apartment Leak Questions
Still have a question? Call us any time at (714) 439-5275.
Can you find which unit the leak is coming from?
Yes. We close off units and lines one at a time and test each one. Then we pinpoint the leak inside the right unit.
Do tenants need to leave during testing?
Usually not. We only enter the units the search needs, and water is shut off only for short periods when testing calls for it.
Who should I call about a water leak in my apartment?
Tell your landlord or property manager first. They can call a leak detection company to trace the source.
How do you find a water leak in a commercial building?
We check the meter, close off zones one at a time, and use moisture, thermal and listening tools to pinpoint the leak.
Do you work with HOAs and property managers?
Yes. We work with owners, HOAs and managers, and explain the findings so everyone knows where the water came from.
How much does commercial leak detection cost?
It depends on the size of the building, the number of units involved, and how easy the lines are to reach. Call us and we'll explain what the inspection involves before you book.
How do I get ready for the visit?
Let tenants near the leak know about the visit, and have access ready for those units. Have the building's water bills and any notes on where water showed up. Know where the main and unit shut-offs are.
