How to Spot & Stop Water Leaks in Union City Homes

Hidden water leaks in Union 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.

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.

Five clues you may have a hidden leak:

1. Stains on ceilings or bubbling paint along walls.

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

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

4. Mildew odors or persistent humidity in specific rooms.

5. Water meter movement even when all fixtures are closed.

Why leaks happen:

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

- Aging copper with pinhole corrosion from water chemistry.

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

- Old galvanized piping rusting from the inside out.

Our step‑by‑step approach:

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

Step 2: Restore finishes neatly and verify with a final pressure test.

Step 3: Confirm with pressure testing or tracer gas for small, silent leaks.

Step 4: Isolate lines to narrow the suspect branch without opening walls.

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.

- 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.
