Trusted Walnut Creek Water Leak Detection Pros — Find It, Fix It, Prevent It

In Walnut Creek, 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.

Older bungalows and mid‑century homes benefit from proactive valve and supply line upgrades.

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

Watch for these warning signs:

- Water meter movement even when all fixtures are closed.

- Efflorescence or damp lines on foundation walls.

- Unexplained spikes on your water bill despite normal use.

- Mildew odors or persistent humidity in specific rooms.

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

Why leaks happen:

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

- Old galvanized piping rusting from the inside out.

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

- Slab movement and soil conditions stressing buried pipes.

How we find the exact source without guesswork:

- Tracer gas for ultra‑small leaks where water noise is minimal.

- Pressure testing of isolated branches to confirm breaks without demolition.

- Acoustic listening to locate pressurized leaks behind walls and under slabs.

- Borescope or camera inspection to distinguish supply leaks from drain issues.

Prevention plan for peace of mind:

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

- Replace old angle stops and braided supplies proactively.

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

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