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.
Make the room as airtight as possible by taping plastic sheeting over doorways and windows. Fire up the equipment, keep a close eye on the dehumidifier's collection well, and regularly check progress with your moisture meter. On average, it takes three days to completely dry wet drywall.

You may ask yourself, “Does water damaged drywall need to be replaced?” But more often than not – the answer is yes! Wet and mold-filled wet walls will lose its structural integrity. Its insulation between your home's studs means an unhealthy and dangerous living space.
The structural integrity of the wall has simply taken too much damage and is compromised. If you measured the moisture of the drywall and received a reading of higher than 1% a replacement is needed.
Walls made of drywall or sheetrock are very porous which makes them susceptible to mold as long as there is a constant level of humidity and moisture in the air. The wood particles on drywall provide a source of food for mold and traps moisture, which speeds up its growth.
The 48-72 hour window is critical to prevent mold growth as it usually takes 24 to 48 hours for mold to germinate and grow. Once fungus gets a hold on a drywall surface, it can be the breeding ground for thousands of spores and quickly spread in the air around the wall with every passing hour.
While small amounts of water damage may not seem like a big deal at first, mold and mildew can quickly grow on the drywall's damp areas. Mold can potentially cause severe health risks such as headaches, fatigue, and respiratory disease for anyone inside your home.
If your drywall is absorbing moisture, you might notice the dark, spotty stains that indicate mold growth. You may see some fuzzy growth, or irregular spots ranging in color from brown or black to green and even pink. Or, you might notice bubbling or peeling paint, which indicates water damage as well as possible mold.

Yes, mold growth can occur even after a leak has been fixed.

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.
Any water leak carries the risk of mold growth, but that doesn't necessarily mean that mold growth is certain. The chance of mold depends on many factors, such as the severity of water damage, how quickly it was cleaned up and dried, and the extent of surfaces affected.
mildew and mold will develop within 24-48 hours of water exposure. Even worse, it will continue to grow until steps are taken to eliminate the source of moisture, and effectively deal with the mold problem.
Exposure to damp and moldy environments may cause a variety of health effects, or none at all. Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin.
But some are deadly, such as toxic black mold. Toxic black mold can release spores as it feeds on common household materials such as drywall, carpet, insulation, or sub-flooring that have been exposed to moisture.
Black mold thrives on water and porous material like drywall or wood which commonly mix in areas like ceilings, basements, and crawl spaces.
