Water DamageCeiling Water Damage Repair Cost Calculator
A stained or sagging ceiling usually means a leak above — a roof, a pipe, or an upstairs bathroom. Enter the damaged ceiling area for a repair estimate.
Repairing a water-damaged ceiling typically costs $400–$1,500 for a localized area — roughly $10–$20 per square foot of affected ceiling once drywall, texture, and paint are included. Finding and fixing the leak above is a separate cost.
How this calculator works
We price the damaged ceiling area for drywall cut-out and replacement, then add a flat amount for matching texture and repainting. The estimate assumes the leak above has been found and stopped — that repair (roof or plumbing) is separate.
What changes the number
- Matching existing ceiling texture (popcorn, knockdown) adds labor.
- A sagging or collapsed section costs more than a simple stain.
- The leak source — roof vs plumbing — is a separate, sometimes larger, repair.
- Insulation above the ceiling may be wet and need replacing.
Ceiling water damage repair cost by damaged area
At the calculator’s default $9/sq ft plus $250 for paint and finishing. A single stained patch from an overflowing upstairs bath is the 10–25 sq ft case; a collapsed section under a long-running roof leak is the 100–200 sq ft case. These figures cover the ceiling itself — finding and fixing the leak above it is separate, and has to happen first.
| Affected area | Typical range | Midpoint estimate | All-in per sq ft |
|---|---|---|---|
| 10 sq ft | $272–$476 | $340 | $34.00 |
| 25 sq ft | $380–$665 | $475 | $19.00 |
| 50 sq ft | $560–$980 | $700 | $14.00 |
| 100 sq ft | $920–$1,610 | $1,150 | $11.50 |
| 200 sq ft | $1,640–$2,870 | $2,050 | $10.25 |
Frequently asked questions
How much does it cost to fix a water leak in the ceiling?
The ceiling repair itself is usually $400–$1,500 for a localized area (about $10–$20 per sq ft). Fixing the leak above — a roof or plumbing line — is a separate cost that can range from a small plumbing fix to a larger roof job, so find and stop the leak first.
Can I just paint over a water stain?
Only after the leak is fixed and the area is fully dry — and you’ll want a stain-blocking primer. If the drywall is soft or sagging, it needs replacing, not painting.
How do I know if ceiling water damage caused mold?
Persistent dark spots, a musty smell, or damage that’s been wet for more than a couple of days all point to possible mold above the ceiling.
How much does it cost to repair a water-damaged ceiling?
A single stain or soft patch of 10–25 square feet runs $270–$670; a 100 square foot damaged section $920–$1,610. At the default $9 per square foot plus finishing, 50 square feet is about $700. That is the ceiling only — the leak above it is a separate repair and has to be fixed first.
Should I repair or replace a water-damaged ceiling?
Repair the patch if the drywall is still firm and the stain is the only symptom. Replace the section if it sags, feels soft, has crumbling joint compound, or if the water sat for more than a couple of days — wet drywall loses strength permanently and painting over it hides a problem rather than fixing one.
Will a water stain on the ceiling come back through new paint?
Yes, unless you seal it first. Water stains bleed through latex paint no matter how many coats you apply — you need a stain-blocking shellac or oil-based primer over the dried stain before repainting. This is the single most common DIY ceiling mistake.
How long does a water-damaged ceiling take to dry?
Two to five days with air movement and a dehumidifier, longer if insulation above it got wet — wet insulation holds water against the drywall and usually has to come out. Do not close the ceiling up or repaint until a moisture meter reads normal, or you seal mold inside.
