Water Damaged Ceiling: How to dry and repair your ceiling to prevent mold

Water damage often happens to ceilings from a roof, water pipe, or air conditioning leak in the attic crawl space area.

When water leaks onto the wood rafters and drywall below, it can cause serious damage to your ceiling and walls.

Drywall is porous and will absorb water like a sponge, even after a very short amount of time.

The longer you wait to dry it out, the more likely it will cause mold growth and further problems.

The best way to repair your ceiling is to dry out the area as quickly as possible.

With drywall, the best route is usually to cut out the affected areas and dry the wall cavities with fans and a dehumidifier.

If your in a situation with a water-damaged ceiling, here are some tips for drying and repairing it:

Step 1: Safety

Make sure the area is safe. If there’s any chance that the ceiling could collapse from the weight of water on top of it, make sure no one uses the room until it’s completely dry and stable again.

Turn off the electricity or gas to prevent an electrical fire or explosion due to a damaged pipe. You should also turn off any ventilation systems in the house, such as fans and vents.

Step 2: Stop source of leaks

If there is a leak in your home, it could be coming from pipes, a roof, or even appliances such as dishwashers, washing machines or refrigerators.

If you do find a leak, then you need to fix it as soon as possible.

You can also simply turn off the water supply and contact a plumber for assistance with fixing the underlying issue.

Step 3: Remove furniture and other items

Remove any wet materials in your home that are not damaged by water, such as furniture and carpeting, so they do not absorb more moisture from the wet walls or ceiling. You can place them in another room.

Step 4: Cut out wet drywall

Wet drywall should be cut out because of the risk of mold and it is also standard protocol in the restoration industry.

Make sure you put plastic or a drop cloth below the area that needs to be cut out.

You will need a good ladder, multi-tool, drywall saw or box blade to cut the drywall.

You want to cut out all the wet drywall. If you have a moisture meter, use that or you can start cutting the area you know is wet and then proceed until you can see that it is not water damaged anymore.

It is a good idea to make the cuts as clean as possible so the repairs are easier.

Step 5: Dry Out Your Ceiling

Next, you want to remove all excess moisture from your ceiling area by using fans and dehumidifiers.

Fans will circulate air and help evaporate moisture from the surface of the wood, while dehumidifiers draw moisture out of the air using refrigeration technology.

You can rent them from many Home Depot stores if they have them in your area.

This will help prevent additional damage to your walls or floors while drying out the area.  It can take several days (3-4) to properly dry before you want to make repairs.

Step 6: Removing or Preventing Mold

Mold and mildew are two common problems that occur when there is standing water in an area for too long of a period of time.

If there is a little mold then you can most likely remove it yourself if you use the proper tools and safety protocols. But if there is a lot or you have health issues, I do not recommend that you attempt to do this yourself because of the dangers involved.

If there is no mold, you should also spray the wall cavity with a good antimicrobial spray to prevent it from growing in the future. This will help ensure, along with the drying methods listed to stop mold from growing.

Step 7: Repair the Ceiling

If you are not too handy or familiar with repairing drywall, then repairing them will be difficult. I do not recommend it because your ceilings are a main feature in your home and if you perform a bad repair, it may look terrible.

You may need to hire someone who specializes in drywall repairs to come out and give you an estimate.

If you cannot afford to hire anyone, then there are many great videos on Youtube like this one below that shows you how it’s done.
