### How much drywall do I need to remove after a flood?
The amount of drywall to be removed after a flood depends on the severity of the damage. Generally, if the drywall is saturated with water or has started to rot, it should be removed and replaced.
**Determining the extent of the damage:**
* **Visual inspection:** Look for signs of water stains, discoloration, or bulging.
* **Moisture meter:** Use a moisture meter to measure the moisture content of the drywall. If the reading is above 16%, the drywall is likely damaged.
* **Probe the drywall:** Gently probe the drywall with a screwdriver or knife. If it feels soft or crumbly, it is probably damaged.
**Removing the damaged drywall:**
* **Safety first:** Wear gloves, a mask, and eye protection. Turn off the electricity before cutting into the drywall.
* **Cut the drywall:** Use a utility knife to cut around the damaged area, leaving a clean edge.
* **Remove the drywall:** Carefully remove the damaged drywall and dispose of it properly.
* **Clean the area:** Clean the area behind the drywall to remove any mold or debris.
**Determining the replacement drywall:**
* **Measure the area:** Measure the width and height of the damaged area to determine how much drywall is needed.
* **Choose the right type of drywall:** There are different types of drywall available, such as moisture-resistant and fire-resistant. Choose the appropriate type based on the location of the damage.
* **Cut and install the new drywall:** Cut the new drywall to size and install it using drywall screws or nails.
