Water Leak Detection & Repair in Berkeley — Fast, Non‑Invasive, Guaranteed

In Berkeley, 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.

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

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

Five clues you may have a hidden leak:

1. Stains on ceilings or bubbling paint along walls.

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

3. Soft drywall, swollen baseboards, or warped flooring.

4. Water meter movement even when all fixtures are closed.

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

Why leaks happen:

- Old galvanized piping rusting from the inside out.

- Improperly crimped PEX fittings or degraded rubber washers.

- Worn angle stops, supply lines, and toilet fill valves.

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

Our step‑by‑step approach:

Step 1: Confirm with pressure testing or tracer gas for small, silent leaks.

Step 2: Acoustic listen and thermal scan to triangulate the leak position.

Step 3: Open a small access point and make a clean, permanent repair.

Step 4: Restore finishes neatly and verify with a final pressure test.

Step 5: Isolate lines to narrow the suspect branch without opening walls.

Prevention plan for peace of mind:

- Install leak alarms under sinks, behind washers, and near water heaters.

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

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

- Replace old angle stops and braided supplies proactively.

Recent job in Berkeley: Repeated meter movement with fixtures off pointed to a pinhole behind the laundry. A
small access panel let us repair the copper and install new shut‑offs, saving the client from tearing out a
full wall.

Expect tidy work, labeled shut‑offs, and a walkthrough before we leave. If you’re seeing signs of a leak in
Berkeley, acting early prevents bigger repairs later.
