Finding the source above the ceiling
A ceiling leak with no rain behind it almost always comes from plumbing above: a failed shower pan, a toilet wax ring, a cracked drain or a supply line to a sink. In townhomes and stacked units the water often crosses into a neighbour's ceiling too.
The tech reads moisture in the ceiling below and the floor above, checks the bath with a thermal camera and narrows the source before anything is cut. A plumber repairs the leak, and the drying team handles the wet ceiling, joists and subfloor.
Opening the ceiling safely
- Sagging or water-filled drywall is drained and removed
- Light fixtures in the wet area stay off until checked
- Wet insulation in the joist bay comes out
- The subfloor above is dried from below through the opening

When water crosses into another unit, both sides need readings and photos. The moisture map shows where the water went and helps each owner and their insurers sort out the claim.
