A basement can be dried out by opening the door(s) and turning on fans to circulate the air. A dehumidifier should then be used until to complete the job.
If there are damp objects like carpets, make sure to remove it. Then, set up several fans in the basement, don't forget to open the doors and windows so the air can circulate around and eventually dry it out.
The best way is to set up severals fans and open the windows and doors so the air can circulate and dryout the basement. Just let the fans run for a few hours.
Drying out a basement can be a time-consuming task, depending on how wet it is. One good way to begin is to put in a strong dehumidifier, and to let it run constantly in the basement.
You can keep the doors or windoes open in the area where the basement is wet. By allowing the air circulation the basement can be dried out. When the temperature is very hot it is very easy for drying but when there is dampness we can use the fan for drying.
