The short answer
Stop the Water Source First
Before you dry anything, find where the water came from and stop it. Turn off the water supply if a pipe leaked, or fix the leak if you can. If the water came from outside, like during heavy rain, check for roof or window issues. Acting quickly helps prevent more damage.
If you live in Daytona Beach, keep your shutoff valve location written down. In a humid climate, moisture lingers longer, so drying needs to be thorough. Once the water is off, you can start the drying process without worrying about new water soaking in.
Remove Wet Baseboards and Furniture
Pull furniture away from the wet wall and remove any baseboards or trim that are soaked. Baseboards often trap moisture against the drywall, slowing the drying process. Set them aside to dry separately if they are still in good shape.
Check the wall for soft spots, bubbling paint, or sagging. If the drywall feels spongy or crumbles when pressed, removal may be needed. If it feels solid, you can proceed with drying. Move rugs and other items away from the area to let air circulate.
- Turn off electricity to the room if water is near outlets or switches.
- Open windows if the outdoor air is drier than indoor air.
- Use a moisture meter to track the wall's dampness over time.
- Point fans at the wall, not just at the floor.
- Run a dehumidifier continuously for several days.
- Check the wall daily for signs of mold or worsening damage.
Set Up Fans and Dehumidifiers
Place high-velocity fans so they blow air across the wet wall surface. Aim them slightly downward to push moisture out of the wall cavity. For a deeper dry, you may need to drill small holes near the base or top of the wall to let air enter the space behind the drywall.
Run a dehumidifier in the room to pull moisture from the air. Keep the room closed off from the rest of the house to concentrate the drying effort. Check the humidity level with a hygrometer; a reading below 50 percent is a good target.
Know When to Remove the Wall
Removal is necessary if the drywall becomes soft, crumbles, or shows dark stains that spread. Mold can grow inside a wet wall within a couple of days, especially in a warm, humid climate. If you smell a musty odor, that is a warning sign.
If the water was contaminated, like from a sewer backup or flood, removal is safer because porous materials cannot be fully cleaned. For clean water that is dried quickly, the wall may survive. When in doubt, a water damage inspection can tell you how deep the moisture went.
- Soft spots that indent when pressed.
- Sagging or bulging sections of drywall.
- Peeling paint or wallpaper that bubbles.
- A musty smell that does not go away.
- Visible mold growth on the surface.
- Water that has soaked into insulation.

How long does it take to dry a wet wall without removing it?
Drying can take several days, depending on how wet the wall is and the airflow. With fans and a dehumidifier running constantly, a mildly damp wall may dry in two to three days. Heavily soaked walls can take a week or longer.
Can I dry a wet wall with a hair dryer?
A hair dryer is not powerful enough for a whole wall. It only heats a small area and can push moisture deeper. Use large fans and a dehumidifier instead, which move more air and remove humidity from the room.
What if the wall is wet behind wallpaper?
Wallpaper traps moisture, so you may need to peel it back or remove it to let the wall dry. If the wallpaper is bubbled or peeling, it will likely need to be stripped. Check the drywall underneath for softness before deciding to keep it.
