Here is an example what can happen when a small water damage is not address quickly. This was truly a small water leak. The pipe was repaired, but they didn't address the water.
As you can see, although there is not a huge amount of mold, the moldy material is in a very tough spot to work. Proper removal protocols will require containment barriers and negative pressure. Although the removal of materials was difficult, the rebuild was even worse! Multiple trade unions were involved, and lots of additional work is required to get this commercial building back "Like it never even happened."
