Finished Basement Contractors Pittsburgh - There are several approaches to help avoid moisture damage problems at a basement. The first rule of thumb isn't a dirt basements. Although these are somewhat less common in this day in age, it is a good idea to point out that dirt flooring not just hold a large amount of moisture but also can give off a number of gases. When building a basement, make certain that you've got a floor drain with a trap installed in the lowest point of the ground.
Without a floor drain, any water that is spilled inside cannot escape. Sump pumps are usually used where flood due to a high water table may be a problem. In addition, waterproof the outside of the base walls and put in a perimeter drainage system. An often overlooked problem in basements is moisture that comes from humidity.
The simplest way to control humidity would be to exhaust water vapor generated in the house to the outside. Indications of high humidity comprise condensation on walls, pipes or other surfaces as well a general awareness of moisture in the atmosphere, dampness, and smells. Often, the humidity will be caused by exposing the basement to external air (open windows), using wet laundry hung to dry in the basement, keeping firewood in the basement, or a drier vent that exhausts inside.
In summer, use a portable air conditioner or air conditioning to decrease humidity. In warm, humid weather, maintain basement windows closed. Run the furnace fan continuously to circulate house air. The real key to keeping basement humidity would be to keep them well ventilated and keep additional moisture from the basement.
