What Causes Leaks — and How We Fix Them in Belmont
Hidden water leaks in Belmont 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.
Townhomes and condos with shared walls need clean, low‑impact detection techniques.
Five clues you may have a hidden leak:
1. Warm spots on floors or damp carpet over slab areas.
2. Water meter movement even when all fixtures are closed.
3. Hissing sounds behind walls or near fixtures when water is off.
4. Soft drywall, swollen baseboards, or warped flooring.
5. Mildew odors or persistent humidity in specific rooms.
Why leaks happen:
- Slab movement and soil conditions stressing buried pipes.
- Over‑pressurized systems without a working PRV or expansion tank.
- Improperly crimped PEX fittings or degraded rubber washers.
- Worn angle stops, supply lines, and toilet fill valves.
How we find the exact source without guesswork:
- Borescope or camera inspection to distinguish supply leaks from drain issues.
- Acoustic listening to locate pressurized leaks behind walls and under slabs.
- Thermal imaging to find temperature anomalies around hot‑water lines.
- Tracer gas for ultra‑small leaks where water noise is minimal.
Prevention plan for peace of mind:
- Replace old angle stops and braided supplies proactively.
- Keep water pressure in spec with a functional pressure‑reducing valve (PRV).
- Install leak alarms under sinks, behind washers, and near water heaters.
- Know where your main shut‑off is and make sure it turns easily.
Case snapshot (Belmont): 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.
