How Upstairs Sink Leak Into Ceiling Cleanup Works in Ontario

1. Extract water beneath the fixture

   The crew removes standing water from the lower room before it reaches more flooring and trim. The plumber handles the upstairs source.

2. Trace moisture across the ceiling

   A moisture meter finds wet pockets around a ceiling seam and nearby trim. The crew follows that measured path into the lower room.

3. Open material that traps water

   A sealed ceiling can hold water against joists. The technician creates access where readings and material condition show it is needed.

4. Dry the structure and verify readings

   The last step is a moisture check, not a visual guess. The technician saves the readings before the ceiling is closed and finished.

What to Do Before the Crew Arrives

The painted surface may look dry while water sits above it. A technician checks the hidden assembly before deciding the dry-out is complete.

• Stop running the upstairs sink until the plumber fixes the leak.
• Close the fixture valve only from a dry, safe position.
• Keep stored cleaners away from children if the cabinet is wet.
• Avoid wet lights and bowed ceiling sections downstairs.
