Mold vs. Mildew: What's the Difference?
Mildew and mold are both fungi, but they behave — and require attention — differently.
Mildew
Mildew grows on flat surfaces, appears white, gray, or yellow, and stays powdery or downy. It usually cleans up with a surface product.
Mold
Mold penetrates surfaces, grows in colonies, and can appear black, green, brown, or fuzzy. It often signals a deeper moisture problem and may require professional evaluation.
When to test
If growth returns after cleaning, spreads, or is accompanied by musty odors, professional testing helps identify the species and locate the moisture source.

Frequently Asked Questions
When should I call a professional mold inspector?+

Do you offer inspections outside of business hours?+
Yes — Platinum Mold Testing is available 24 hours a day, 7 days a week for emergencies and scheduling flexibility.
