Mold

Mold is a fungus that grows on damp surfaces and can cause health problems and material damage.

Why it matters

Mold needs moisture to grow. Controlling moisture through air sealing, ventilation, and leak repair prevents mold.

Where people get this wrong

Bleach does not always kill mold. Cleaning visible mold without fixing the moisture source allows it to return. Some mold is hidden in walls.

Real-world example

A musty smell appears in a bathroom. Black spots show up in the corners. The exhaust fan was not vented outside, and moisture built up.

Where this hits your build

This term shows up during construction and affects decisions that are hard to reverse once the work moves forward. Understanding it now saves time, money, and frustration later.

Most people do not just struggle with terms. They struggle with the decisions tied to them.
