Hidden Leak Warning Signs & What to Do in Fremont
Hidden water leaks in Fremont 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.
Five clues you may have a hidden leak:
1. Water meter movement even when all fixtures are closed.
2. Unexplained spikes on your water bill despite normal use.
3. Hissing sounds behind walls or near fixtures when water is off.
4. Warm spots on floors or damp carpet over slab areas.
5. Stains on ceilings or bubbling paint along walls.
Why leaks happen:
- Worn angle stops, supply lines, and toilet fill valves.
- Over‑pressurized systems without a working PRV or expansion tank.
- Old galvanized piping rusting from the inside out.
- Improperly crimped PEX fittings or degraded rubber washers.
Our step‑by‑step approach:
Step 1: Confirm with pressure testing or tracer gas for small, silent leaks.
Step 2: Restore finishes neatly and verify with a final pressure test.
Step 3: Isolate lines to narrow the suspect branch without opening walls.
Step 4: Acoustic listen and thermal scan to triangulate the leak position.
Step 5: Open a small access point and make a clean, permanent repair.
Prevention plan for peace of mind:
- Install leak alarms under sinks, behind washers, and near water heaters.
- Schedule an annual whole‑home plumbing check to catch small issues early.
- Keep water pressure in spec with a functional pressure‑reducing valve (PRV).
- Replace old angle stops and braided supplies proactively.

full wall.
