Anderson Basement Hopper Windows - There are several ways to help prevent moisture damage problems at a basement. The very first rule of thumb is no dirt basements. Though these are less prevalent in this day in age, it is a good idea to point out that dirt flooring not only hold a huge amount of moisture but can also give off a number of gases. When building a basement, make sure you have a floor drain with a trap installed at the bottom point of the floor.
With no floor drain, any water that is spilled inside cannot escape. If necessary, install a sump pump and make sure the sump cover is tightly sealed. Sump pumps are often used where flooding due to a high water table might be a issue. Additionally, waterproof the exterior of the foundation 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 is to exhaust water vapor generated in the house to the exterior. Signs of high humidity comprise condensation on walls, pipes or other surfaces as well an overall sense of moisture from the atmosphere, dampness, and smells. Many times, the humidity is going to be caused by exposing the basement to external air (open windows), having wet laundry hung to dry from the basement, storing firewood from the basement, and/or a dryer vent that exhausts inside.
In summer, use a portable dehumidifier or air conditioning to reduce humidity. In hot, humid weather, maintain basement windows shut. Run the furnace fan continuously to circulate house air. The key to keeping basement humidity is to keep them well ventilated and keep additional moisture out of the basement.
