The short answer
Start with Water Removal
Begin by removing any standing water from the floor and the wall surface. Use a wet vacuum or towels to soak up puddles. The sooner you remove the water, the less it soaks into the drywall. In Rowlett, spring storms can bring sudden water into a home, so acting fast matters.
Once the surface is dry to the touch, check for soft spots. Press gently on the wall with your hand. If it feels spongy or crumbles, that part of the sheetrock is damaged. You can cut out those sections with a utility knife, but leave the rest in place for drying.
- Use a wet vacuum for large puddles
- Wipe walls with dry towels
- Cut away sagging or crumbling areas
- Remove baseboards to let air behind them
- Open wall cavities if insulation is wet
Increase Airflow and Dehumidify
After removing the water, set up fans to blow across the wet wall. Point them at the surface, not just into the room. Open windows and doors if the outdoor humidity is low. A dehumidifier helps pull moisture from the air and the wall, speeding up the drying process.
Run the fans and dehumidifier for at least 48 hours, or until the wall feels dry to the touch. In a humid climate, drying can take longer. If you have a moisture meter, use it to check the drywall. A reading above 15 percent means it is still wet and needs more time.
When to Cut Out the Sheetrock
You do not always need to tear out wet sheetrock. If the water was clean and the wall dried within a few days, it may be fine. But if the drywall stays wet for more than a few days, mold can grow inside. Mold in the wall is a health risk and often means you should replace the affected sections.
Cut out any drywall that has visible mold, a musty smell, or that has been wet for more than 48 hours. Remove the entire wet section, going at least 12 inches beyond the water stain. This gives you a clean edge for patching. Dispose of the wet drywall properly, as it can be heavy and messy.
- Visible mold or musty odor
- Wet for more than 48 hours
- Swollen or crumbling edges
- Stains that darken or spread
- Insulation behind the wall is soaked
Drying Without Tearing Out
For minor water exposure, you can dry sheetrock in place. Use a dehumidifier and fans for several days. Keep the room warm to speed evaporation. Check the wall daily for any new soft spots or discoloration. If the wall dries without issues, you can paint over it after it is fully dry.
But drying in place only works if the water was clean and the drywall is not saturated. If the water came from a sewer or flood, the sheetrock should be removed because it can hold contaminants. Also, if the wall has multiple layers, drying may not reach the inner layer. In that case, replacement is safer.
Know When to Call the Pros
Some water damage is too big for a homeowner to handle alone. If the water came from a pipe leak behind the wall, you may need a plumber to fix the source first. If the drywall is heavily damaged or mold is present, local water damage pros can help with structural drying and dehumidification.
The pros use industrial fans and dehumidifiers that dry walls faster than household equipment. They also have moisture meters to confirm the wall is dry. If you are unsure whether your sheetrock can be saved, a water damage inspection can tell you the extent of the damage. Policies vary, and your insurer decides what is covered.

How long does it take to dry sheetrock?
It depends on how wet the drywall is and the humidity level. With fans and a dehumidifier, a lightly wet wall can dry in 2 to 3 days. Heavily saturated drywall may take a week or more. If it stays wet longer, mold can grow, so consider cutting it out.
Can I speed up drying with a heater?
A heater can help, but use it carefully. High heat can cause the drywall to crack or the paper to peel. Keep the temperature moderate and use fans to circulate air. A dehumidifier is more effective at pulling moisture from the wall than heat alone.
What if the sheetrock has mold after drying?
If you see mold, the drywall should be removed. Mold can grow inside the wall even if the surface looks dry. Cut out the affected area and replace it. Wear gloves and a mask while handling moldy drywall. If the mold covers a large area, call a mold professional for safe removal.
