Ceiling stains mean water is traveling — usually from a bathroom or appliance above, or a roof leak. The visible stain is the smallest part of the job: the real scope is the wet cavity above it. Small contained ceiling jobs often land between $500 and $2,500; if the leak ran long enough to saturate insulation and framing, $2,500–$6,000+ is common. And a sagging ceiling is a safety issue — water is pooled above it.
| Scope | Typical range | Notes |
|---|---|---|
| Stain sealing + repaint | $200–$600 | Only appropriate after the source is fixed AND the cavity is confirmed dry. |
| Drywall cut-out + replace | $300–$1,200 | Typical for a single affected section with insulation replacement. |
| Full section rebuild | $1,500–$4,000+ | Multiple joist bays, saturated insulation, mold treatment. |
| Source repair (roof/plumbing) | separate line item | Roof leak repair or plumbing fix is quoted separately from the ceiling restoration. |
Only after the leak is fixed and the area is verified dry with a moisture meter. Painting over a wet or moldy cavity seals the problem in and guarantees it comes back worse.
Yes — it means water weight is pooled above the drywall, which can collapse without warning. Stay out of the room and call a professional. Don't poke it to 'drain' it yourself.
Water travels along joists and pipes, so the stain is rarely directly under the source. Pros use moisture meters and infrared to trace it. Common sources: supply lines, drain lines, shower pans, and roof penetrations above.
