The short answer
Assess the Damage First
Before you touch the ceiling, find and stop the water source. That could mean turning off a valve or patching a roof leak. If the ceiling is actively dripping, place a bucket underneath and wait for it to dry completely. Wet drywall is heavy and can collapse without warning.
Check the area for soft spots, sagging, or discoloration. Press gently around the stain with your hand. If the surface feels spongy or moves when you push, the drywall has lost its strength. A small, hard stain that has dried for several days is a different story and might be safe to refinish.
When DIY Is Risky
Cutting into a water-damaged ceiling exposes wires, pipes, and insulation. You might hit a live electrical line or a hidden leak. Water can also travel along joists, so the visible stain may be only part of the problem. If the ceiling is sagging, the entire section may need removal.
Mold can grow inside the wall cavity after a leak, even if you don't see it. Disturbing moldy drywall releases spores into your air. If you notice a musty smell or dark spots, that's a sign to stop and call in the pros. They have the tools to dry, disinfect, and rebuild safely.

Small Stain Repair Steps
For a small, dry stain, you can do the work yourself. First, scrape away loose paint and drywall compound with a putty knife. Then, apply a stain-blocking primer to seal the water mark and prevent it from bleeding through the new paint. Let that dry completely.
Next, fill any holes with joint compound and sand smooth. Apply a second coat of primer if needed. Finish with two coats of ceiling paint, using a roller for an even texture. This works only when the drywall is still solid and the leak has stopped permanently.
When to Call the Pros
If the ceiling is soft, sagging, or has a large area of damage, professional help is worth the cost. The pros will cut out the wet drywall, dry the framing, and treat any mold before installing new board. They also have the equipment to handle hidden moisture in the structure.
You should also call the pros if the leak came from a plumbing pipe or the ceiling is two stories up. Working overhead is tiring and dangerous. A professional can do the job faster and with less mess, and they can spot issues you might miss, like damaged insulation or corroded fasteners.
Cost and Insurance Factors
Repair costs vary widely. A simple stain repair might cost a few hundred dollars, while a full ceiling replacement can run into the thousands. The final price depends on the size of the damaged area, the cause of the leak, and how much drywall needs to be removed.
If the water damage came from a sudden event, like a burst pipe, your insurance may help. Check your policy to see what is covered. Policies vary, and your insurer decides what is covered. Document the damage with photos before any work begins, and keep receipts for materials you buy.

How long does a wet ceiling take to dry?
Drying time depends on the extent of the water and the air circulation in the room. A small stain might dry in a few days, but a soaked ceiling can take a week or more. Use fans and dehumidifiers to speed up the process. Do not paint over a wet spot.
Can I paint over a water stain?
You can paint over a dry stain after applying a stain-blocking primer. Regular paint will not hide the discoloration and the stain can bleed through. Clean the area first to remove any residue. If the stain is still damp or the ceiling is soft, painting will not fix the underlying problem.
What if the ceiling is sagging?
A sagging ceiling is a serious safety hazard. It means the drywall is saturated and could collapse at any time. Do not stand directly under it. Turn off the power to that room if wires are nearby, and call a professional to assess the situation. Do not attempt to push it back up.
