Stop Hidden Water Damage in San Leandro — Licensed Leak Detection & Repair

In San Leandro, small leaks rarely stay small. A pinhole in a copper line can soak drywall, warp flooring, and
invite mold long before a puddle appears. Our licensed team uses non‑invasive diagnostics to find the source
quickly and repair it cleanly.

Hillside lots and longer plumbing runs can mask leaks until surfaces show damage.

Remodeled kitchens and baths deserve shut‑offs that actually shut off — we test every valve.

Five clues you may have a hidden leak:

1. Unexplained spikes on your water bill despite normal use.

2. Stains on ceilings or bubbling paint along walls.

3. Warm spots on floors or damp carpet over slab areas.

4. Hissing sounds behind walls or near fixtures when water is off.

5. Mildew odors or persistent humidity in specific rooms.

Why leaks happen:

- Aging copper with pinhole corrosion from water chemistry.

- Over‑pressurized systems without a working PRV or expansion tank.

- Old galvanized piping rusting from the inside out.

- Slab movement and soil conditions stressing buried pipes.

Our step‑by‑step approach:

Step 1: Isolate lines to narrow the suspect branch without opening walls.

Step 2: Confirm with pressure testing or tracer gas for small, silent leaks.

Step 3: Restore finishes neatly and verify with a final pressure test.

Step 4: Open a small access point and make a clean, permanent repair.

Step 5: Acoustic listen and thermal scan to triangulate the leak position.

Prevention plan for peace of mind:

- Schedule an annual whole‑home plumbing check to catch small issues early.

- Keep water pressure in spec with a functional pressure‑reducing valve (PRV).

- Replace old angle stops and braided supplies proactively.

- Know where your main shut‑off is and make sure it turns easily.
