How to Remove Mold from Drywall

How to remove mold from drywall

Mold on drywall isn’t just unsightly—it can affect your air quality, health, and peace of mind. While small patches may seem easy to clean, mold can release mycotoxins and spores that spread through your HVAC system, contaminating other areas of your home. Let’s walk through how to clean it properly—and when to call in the pros.


🛠️ Step-by-Step Mold Removal from Drywall


✅ Step 1: Fix the Moisture Source

Before cleaning, address the cause of mold growth.
💧 Common culprits: leaks, humidity, poor ventilation.
🛁 Example: Install an exhaust fan if mold is growing on bathroom walls.


✅ Step 2: Use White Vinegar (Not Bleach!)

Spray white vinegar generously on the affected area.
⏱️ Let it sit for
5–15 minutes to penetrate the surface.
🚫 Avoid bleach—it can worsen air quality and damage drywall. Also, it doesn't kill mold, it makes it worse!


✅ Step 3: Wipe & Retreat

🧽 Wipe the mold away with a clean cloth.

💨 Let it dry completely. Using a dehumidifier will speed up the process.
🔁 Reapply vinegar to the same spot and surrounding areas to ensure full coverage.


✅ Step 4: Prime & Paint

🎨 Use Kilz or  Zinsser   primer to seal the area.
🖌️ Once dry, repaint with your preferred color for a fresh finish.



⚠️ Important Safety Notes

  • ❌ Never clean mold patches larger than 10 square feet yourself.
  • 🧬 Disturbing mold releases spores that can spread through your home.
  • 🫁 Exposure to mold spores may cause respiratory issues, especially in children, seniors, and those with allergies.
  • 🛑 DIY fixes often fail when mold is covered up instead of removed—leading to recurring growth.
