When drying water damaged walls you have to know what you're working with. Always address health and safety issues first that’s number one priority. What kind of materials are we trying to dry and how wet is the material? Majority of the time real wood dries in 2 days, as drywall typically takes 3 days.
Extraction, air movers and a dehumidifier is key. Number of equipment would depend on what’s wet, how much is wet, and how wet is it. Response time, Category of water and amount depends on if your walls are able to be saved. What type of insulation is inside the wall cavity makes a difference as to whether the wall can be dried in place or needs to be removed. If there is fiber glass insulation in the wall, those walls typically can be dried in place unless water has penetrated from above and crushed the insulation down. Walls with blown in insulation can’t be dried in place and the affected wall will need to be removed along with the affected insulation.
