Mold Following Previous Water Damage
When mold is discovered after a past water event, whether the original water was fully cleaned up recently or some time ago, mold remediation is generally treated as a distinct service from the original water damage cleanup.
Why this happens
Materials that were not fully dried, or areas that were not visible during the original cleanup (such as inside a wall cavity or under flooring), can allow mold to develop even after standing water has been removed.
What to check for
Visible discoloration, a musty odor, or discomfort in a previously affected area are worth noting. See the related article on how quickly mold can develop after water damage for general timing information.

Frequently Asked Questions
Why did mold appear after my water damage was cleaned up?
Materials that were not fully dried, or areas not visible during the original cleanup such as inside a wall cavity or under flooring, can allow mold to develop even after standing water has been removed.
Is mold remediation the same as water damage cleanup?
No. Water damage cleanup focuses on removing water and drying the property. Mold remediation focuses on containing and removing existing mold growth and addressing the moisture conditions that allowed it to develop. A property can need one without the other.
How long after water damage can mold still appear?
Mold can begin developing within roughly 24 to 48 hours in favorable conditions, but it may not become visible or noticeable for considerably longer if it develops inside a wall cavity, under flooring, or in another concealed area.
