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

In Foster City, 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.

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

Watch for these warning signs:

- Efflorescence or damp lines on foundation walls.

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

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

- Unexplained spikes on your water bill despite normal use.

- Stains on ceilings or bubbling paint along walls.

Why leaks happen:

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

- Old galvanized piping rusting from the inside out.

- Aging copper with pinhole corrosion from water chemistry.

- Slab movement and soil conditions stressing buried pipes.

Our step‑by‑step approach:

Step 1: Acoustic listen and thermal scan to triangulate the leak position.

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

Prevention plan for peace of mind:

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

- 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.

Case snapshot (Foster City): A homeowner noticed a warm floor patch near the hallway. Thermal imaging
confirmed a hot‑side slab leak. We isolated the run, performed a clean access repair, and verified with a
pressure hold — all in one day.

Expect tidy work, labeled shut‑offs, and a walkthrough before we leave. If you’re seeing signs of a leak in
