Spotting dark growth on your bathroom ceiling or basement wall can send any homeowner into a panic. Not all dark spots are created equal.

Mildew typically grows flat against surfaces like tile grout window sills or painted walls. It appears as powdery or fluffy spots that are usually white gray or light yellow. When you touch mildew it often smears or wipes away easily with a damp cloth. Mold on the other hand grows in a three-dimensional pattern. It can be fuzzy slimy or even leathery in texture and comes in a wider range of colors including black green red or blue. Mold penetrates porous materials like drywall wood and carpet padding making it much harder to remove completely.
Growth patterns also differ significantly. Mildew spreads outward in a flat even layer across a surface. Mold grows upward and outward in irregular patches or spots that can quickly expand in size.
