Stop Hidden Water Damage in Daly City — Licensed Leak Detection & Repair

Hidden water leaks in Daly City are costly because they travel silently through walls and slabs. We combine
technology and craftsmanship to locate the problem precisely and stop the damage before it spreads.

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.

Watch for these warning signs:

- Soft drywall, swollen baseboards, or warped flooring.

- Efflorescence or damp lines on foundation walls.

- Mildew odors or persistent humidity in specific rooms.

- Stains on ceilings or bubbling paint along walls.

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

Why leaks happen:

- Old galvanized piping rusting from the inside out.

- Improperly crimped PEX fittings or degraded rubber washers.

- Slab movement and soil conditions stressing buried pipes.

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

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: 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:

- 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.

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