When should I test for mold?

There are really only 3 situations when a mold test is necessary:

1. You get sick inside your home with flu-like symptoms and don’t know why

2. After a mold remediation and cleanup to make sure it’s all gone

3. The home you’re buying smells damp and musty, but you don’t see any mold (it might be hiding above ceilings and inside walls)
