A ceiling leak is a symptom, and the job starts with finding the cause. In two-story Naples homes the source is often a bathroom above: a toilet seal, a shower pan, a tub drain or a supply line. In single-story homes it is usually an attic air handler, a water heater in the attic or a roof problem. In condos it is very often the unit above. Water travels along joists, trusses and slabs before it drips, so the stain is not always under the source.
Where ceiling leaks come from
- Toilet wax rings, shower pans and tub drains in upstairs bathrooms
- Supply lines to upstairs sinks, toilets and washers
- Air handler overflows in the attic, covered on the AC condensate page
- Water heaters in attics or upstairs closets
- Roof and flashing leaks, covered on the roof leak page
Tracing and opening the ceiling safely
The tech who does the walkthrough uses thermal imaging and moisture meters to follow the water back toward its source and to map how far the ceiling is wet. A sagging ceiling holds a surprising weight of water, so crews relieve it under control rather than letting it fall. Wet drywall that has lost strength comes out; sound drywall with a small wet area can often be dried in place with air movers, a dehumidifier and a small access hole. Insulation above the wet area is checked and removed if soaked.
Stay out from under a bulge
A bulging or sagging ceiling can fail without warning. Keep people and pets out from under it and turn off ceiling fans and lights in that area.
Plaster, popcorn texture and older ceilings
Older Naples homes may have plaster or textured ceilings, and texture applied before the 1980s can contain asbestos. That material should be tested before it is disturbed, which the EPA asbestos pages explain. The Consumer Product Safety Commission covers home safety hazards more broadly.
