How pinhole leak damage is handled in Fontana
Walkthrough and moisture map
The tech who does the walkthrough finds the source and maps how far the water traveled, with thermal imaging and pinless meters.
Extraction
The extraction crew pulls standing water with truck-mounted extraction so it leaves the building instead of spreading to the next room.
Drying set to the room
The drying team sets air movers to each room's evaporation load and runs LGR dehumidifiers, desiccants for Class 4 materials.
Daily readings to dry
Most crews record readings daily and pull equipment once wet materials sit within 2 to 4 points of a dry reference.
Pinhole leaks are small holes that corrosion opens in copper pipe. They spray a fine mist or drip slowly, often inside a wall or ceiling where nobody sees them. Fontana's hard, mineral-heavy water and older copper plumbing make them a common find. The trouble is time: a slow leak that runs for weeks can turn clean water into a Category 2 loss with mold starting on the back of the drywall.
Clues a pinhole leak is inside the wall
- A small stain or bubble in paint that keeps growing
- A musty smell in one closet or bathroom
- Green or white crust on exposed copper at the water heater or under sinks
- Baseboards or cabinet bottoms swelling with no visible source

Get Fontana pinhole drying startedHow pinhole leak damage is found and dried
The tech who does the walkthrough scans the area with thermal imaging and pinless meters to trace the wet footprint, which is usually wider than the stain. A small inspection opening confirms the source for the plumber. Because the water ran for a while, the mitigation team checks the cavity for growth and treats it with an EPA-registered antimicrobial where needed. Wet insulation and damaged drywall come out, and the cavity dries with air movers and LGR dehumidifiers to the drying goal. The EPA mold guidance explains why the 24 to 48 hour window matters.
One pinhole often means more
When copper starts failing from the inside, other runs of the same age can follow. Plumbers often suggest a repipe after repeat leaks. Water under the floor points to a slab leak instead, and a sudden gush is handled as a burst pipe. The EPA Fix a Leak page shows how to check the meter for hidden leaks.

What causes pinhole leaks in copper pipes?
Corrosion from the inside, usually tied to water chemistry, water velocity and the age of the pipe. Hard, mineral-heavy water and older copper are both common in Fontana homes.
Is a pinhole leak an emergency?
It is urgent even when it is small, because the water has usually been running out of sight. Shut the nearest valve and get the area mapped before the wall grows mold.
Can the drywall be dried instead of replaced?
If the leak was caught early and the water is still clean, often yes. After weeks of dripping, the wet drywall and insulation are usually removed.
Will the smell go away after drying?
Once wet materials are removed or dried and any growth is treated, the musty smell goes with them. Air fresheners only hide it.
Does insurance cover pinhole leak damage?
Policies often treat long-term seepage differently from sudden damage, so how long the leak ran matters. Coverage depends on your policy, so it is worth checking with your own insurer.
Should I repipe after a pinhole leak?
That is a plumbing decision. Repeat pinholes in the same system are a common reason plumbers recommend it.
