Mold From Water Leaks
Leaking water doesn't just happen when something big like a pipe bursts. Something as simple as a dripping faucet going unnoticed for months can cause a leak. While the water damage won't always be apparent. It can still cause mold to grow inside walls or under flooring.
Some mold spores can germinate after just 12 hours of drywall being in wet conditions. How to prevent mold? The only way to prevent mold infestation in drywall following a water damage incident is to dry it within 48 hours after water intrusion.
Use fans to move air around the damp walls. Also use dehumidifiers, which can help remove moisture from the air and walls. Professionals use tools like moisture meters, infrared imaging devices, dehumidifiers and heavy-duty fans. That ensures the walls are truly dry before further repair, painting or refinishing.
Respiratory protection should be worn when removing drywall as some older drywall joint compound contains asbestos. If the water level was less than 2½ feet, the wall material should be removed to a height of 4 feet to facilitate reinstallation of full sheets of drywall.

Extensive water damage is obvious to see. 'Look out for large holes, leaks or sagging in the ceiling, says Adam Graham, construction analyst at Fixr. In this case, the ceiling would need to be fully replaced, including structural elements such as beams'.
Musty Smell

Spray With Cleaning Solution
Use a mixture of water, vinegar and baking soda to spray the moldy spots. Spray the area once or twice so it gets covered but not so much that it drips. Once it's wet you can use a toothbrush or a scrub brush to scrub away any discolorations and mold.
