Silverline Basement Hopper Windows - There are several approaches to help avoid moisture damage problems at a basement. The very first rule of thumb is no dirt basements. Although these are less common in this day in age, it is good to point out this dirt flooring not only hold a huge 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 lowest point of the ground.
Without a floor drain, any water that's spilled inside cannot escape. If needed, install a sump pump and make sure that the sump cover is tightly sealed. Sump pumps are usually used where flood due to a high water table might be a issue. Additionally, waterproof the exterior of the base walls and put in a perimeter drainage system. A frequently overlooked problem in bathrooms is moisture that comes out of humidity.
The easiest way to control humidity would be to exhaust water vapor generated in the house to the exterior. Indications of high humidity comprise condensation on windows, pipes or other surfaces as well a general awareness of moisture in the air, dampness, and odors. Often, the humidity will be brought on by exposing the basement to external air (open windows), having wet laundry hung to dry in the basement, storing firewood in the basement, and/or a dryer vent that exhausts indoors.
In summer, use a portable dehumidifier or air conditioning to reduce humidity. In hot, humid weather, keep basement windows shut. Run the furnace fan continuously to circulate house air. The real key to keeping basement humidity low would be to keep them well ventilated and to keep additional moisture out of the basement.
