Trusted San Bruno Water Leak Detection Pros — Find It, Fix It, Prevent It

Hidden water leaks in San Bruno 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.

Townhomes and condos with shared walls need clean, low‑impact detection techniques.

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

Five clues you may have a hidden leak:

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

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

3. Stains on ceilings or bubbling paint along walls.

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

5. Mildew odors or persistent humidity in specific rooms.

Why leaks happen:

- Improperly crimped PEX fittings or degraded rubber washers.

- Slab movement and soil conditions stressing buried pipes.

- Old galvanized piping rusting from the inside out.

- Aging copper with pinhole corrosion from water chemistry.

Our step‑by‑step approach:

Step 1: Restore finishes neatly and verify with a final pressure test.

Step 2: Open a small access point and make a clean, permanent repair.

Step 3: Acoustic listen and thermal scan to triangulate the leak position.

Step 4: Confirm with pressure testing or tracer gas for small, silent leaks.

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

Prevention plan for peace of mind:

- Replace old angle stops and braided supplies proactively.

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

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

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