Complete Mold Guide

Mold thrives in damp, dark environments with poor air circulation. Common areas include:

• Bathrooms and shower areas
• Basements and crawl spaces
• Attics with roof leaks
• Around windows and doors
• HVAC systems and ductwork
• Kitchen areas with high humidity

Mold appears in various colors and patterns. Visual signs include:

• Black or dark green — often toxic species like Stachybotrys
• White or gray — early-stage growth or Aspergillus
• Orange or pink — less common but still concerning
• Fuzzy or slimy texture — active growth requiring immediate attention
• Musty odor — often precedes visible growth

Don't ignore small spots—mold spreads rapidly when conditions are favorable. Our AI Photo Scan can instantly identify the species and risk level from just a photo.

Prevention is always cheaper than remediation:

• Keep humidity below 50% using dehumidifiers
• Ensure proper ventilation in bathrooms and kitchens
• Fix water leaks immediately
• Use exhaust fans during showers
• Inspect roof regularly for damage
• Clean gutters and downspouts
• Use mold-resistant paint and materials
