Basement Exhaust Fan - There are numerous ways to help prevent moisture damage problems in a basement. The very first rule of thumb isn't a dirt basements. Though these are less prevalent in this day in age, it's a good idea to point out this dirt floors not just hold a large amount of moisture but also can give off a variety of gases. When building a basement, make sure you have a floor drain with a trap installed at the bottom point of the floor.
Without a floor drain, any water that is spilled inside cannot escape. If necessary, install a sump pump and ensure that the sump cover is tightly sealed. Sump pumps are often used where flooding due to a high water table might be a problem. Additionally, waterproof the exterior of the base walls and put in a perimeter drainage system. An often overlooked problem in bathrooms is moisture that comes out of humidity.
The simplest way to control humidity would be to exhaust water vapor produced in the house to the exterior. Signs of high humidity comprise condensation on windows, pipes or other surfaces as well a general sense of moisture in the atmosphere, dampness, and smells. Often, the humidity is going to be brought on by exposing the basement to outside air (open windows), using wet laundry hung to dry in the basement, keeping firewood in the basement, or a drier vent that exhausts inside.
To decrease humidity, there are numerous things a homeowner can do: install energy-efficient windows, insulate walls and cold water pipes, prefinished flooring if at all possible, run drier vents to exhaust directly outside and do not dry laundry or firewood in your basement. In warm, humid weather, maintain basement windows shut. Run the furnace fan continuously to circulate house air. The key to keeping basement humidity low would be to keep them well ventilated and to keep extra moisture out of the basement.
