Assessing and Dealing with Water Damage Determining Drywall Removal Extent

Assessing the Need for Drywall Removal

Following a flood or other water incident, it’s crucial to assess the extent of damage and determine whether drywall needs to be removed. Here are some factors to consider:

  • Water Height: If the water reached above six inches, drywall should be removed from the baseboard to the highest point of water penetration.
  • Duration of Submersion: Drywall submerged for more than 24 hours should be removed, as it has likely absorbed too much moisture.
  • Type of Water: Contaminated water (e.g., sewage) requires immediate removal of affected drywall.
  • Mold Growth: Visible mold on drywall indicates it should be replaced to prevent health risks.
  • Material Degradation: Check for structural integrity. If drywall is soft, crumbling, or bubbling, it must be removed.

Estimating Drywall Removal Volume

To determine the amount of drywall to be removed, measure the affected area and calculate the square footage of drywall that needs to be replaced. Account for the height of the water and the need to remove drywall at least six inches above the waterline.

Drywall Removal Estimates
Flood Water Height Recommended Removal Height Removal Square Footage
6-12 inches 12 inches above waterline Measure affected area and multiply by 1.5
12-18 inches 18 inches above waterline Measure affected area and multiply by 2
Over 18 inches Remove all affected drywall Measure affected area

Additional Considerations

When removing drywall after water damage, be sure to:

  • Wear protective gear (e.g., mask, gloves)
  • Turn off electrical and water sources
  • Ventilate the area during and after removal
  • Dispose of removed drywall properly (e.g., landfill)
  • Inspect underlying framing for damage
