How to Repair Water Damaged Walls
1. Stop water from soaking into walls
You must stop water from getting into your walls before you can repair wetdrywall. To stop water from leaking or bursting pipes, turn off the water shutoff valve. There isn’t anything you can do to stop flooding.
The next step is to get rid of the water as fast as possible. The best way to quickly get rid of water is with a pump. A rental company can rent a water pump if you don’t own one.
You can use a dry-dry vacuum instead of a pump. It won’t work quite as fast, and could cause more damage. Be sure to empty the shop vacuum regularly, or it could overflow onto the floor.
You can also use towels or a bucket to remove the water. No matter what method you use, the goal is to get rid of as much water as possible as quickly as possible. You can’t save walls if it takes longer.
2. Throw Away Damaged Drywall
Throw away any items that are too damaged to be saved once the water has dried. You can throw away personal items and even parts of the wall. It’s best to remove drywall that is cracked, crumbling, or sagging. It can be dried if it is only damp.
Cut drywall that has been damaged by water at least 2 inches above the waterline. Additionally, you may need to replace damaged ceilings, flooring and cabinets, as well as damaged studs.

The fans will keep going until your house is dry. This will normally take between 12 to 24 hours if you have the right fans. With house fans, however, this could take up to five days.
4. Disinfect and Deodorize
After they have dried, disinfect the area and deodorize it. Mix one cup bleach to a gallon water. You can then wipe them with a rag, or spray them with water. Let them dry on the air.
Open windows to let fresh air circulate through the house. Sprinkle baking soda on the area and allow it to sit for at least 24 hours. You can then vacuum it up the next morning.
