Ceiling Water Damage Repair Cost Calculator
Estimate repair cost for a stained, soft or sagging ceiling.
Estimates use typical industry ranges and published methods. They are not a quote. An on-site moisture inspection sets the actual scope.
What's usually above a stained ceiling
- Upstairs bathrooms — failed toilet wax rings, tub drain leaks, and shower pan failures drip slowly for months before the stain appears.
- HVAC in the attic — most Mesquite two-stories and many single-stories keep the air handler in the attic. A clogged condensate drain overflows the pan right onto the ceiling below, especially in peak summer.
- Roof penetrations — around vents, flashing and valleys after hail or wind events. See roof leaks.
- Attic water heaters — a leaking tank or relief valve fills the drain pan and overflows. See water heater leaks.
- Pipes — supply lines routed through the attic, vulnerable in freezes.
If the ceiling is actively bulging
Put a bucket under it and relieve the water with a small screwdriver hole at the low point of the bulge. A ceiling that drains slowly through a small hole is repairable; one that collapses under water weight takes the insulation and sometimes light fixtures with it. Keep people and pets out from underneath, and turn off power to any light fixture in the wet area.
Why you dry the cavity before painting the stain
Painting over a water stain without opening and drying the cavity traps moisture against drywall paper and framing — the exact recipe for mold growth you can't see. Proper repair: locate and fix the source, open or dry the cavity (often from above via the attic), verify with a moisture meter, then patch, texture and paint.
Ceiling repair: what it costs
| Situation | Typical repair | Typical range |
|---|---|---|
| Dry stain, firm drywall | Stain-blocking primer, paint | $150 – $400 |
| Soft or bubbling area | Cut out, patch, texture | $300 – $1,000 |
| Sagging or collapsed | Replace drywall, dry framing, insulation | $500 – $2,500+ |
Matching texture (knockdown, orange peel or popcorn) and repainting the full ceiling so the patch disappears add to the cost. The calculator above adds those for you.
