DIY Mold Removal: When It’s Okay

When to Call a Professional

If the mold covers a large area, it’s time to call in the experts. Mold that has penetrated the drywall or is growing on the back is a serious issue. You might also need professional help if you’ve had a major water event, like a flood. Trying to clean extensive mold yourself can be dangerous and ineffective.
