Carson'S Bargain Basement - There are numerous ways to help avoid moisture damage problems in a basement. The very first rule of thumb is no dirt basements. Though these are less prevalent in this day in age, it is good to point out this dirt flooring not just hold a large amount of moisture but can also give off a number of gases. When building a basement, make sure you have a floor drain using a trap installed in the bottom point of the ground.
Without a floor drain, any water that is spilled inside can't get out. If necessary, install a sump pump and make sure the sump cover is tightly sealed. Sump pumps are often used where flooding because of a high water table might be a issue. In addition, waterproof the exterior of the base walls and put in a perimeter drainage system. An often overlooked problem in basements is moisture that comes from humidity.
The easiest way to control humidity would be to exhaust water vapor produced in the home to the exterior. Signs of high humidity include condensation on windows, pipes or other surfaces as well a general sense of moisture from the atmosphere, dampness, and odors. Many times, the humidity will be brought on by exposing the basement to external air (open windows), having wet laundry hung to dry from the basement, keeping firewood from the basement, or a drier vent that exhausts indoors.
To reduce humidity, there are numerous things that a homeowner can perform: install energy-efficient windows, insulate walls and cold water pipes, prefinished flooring if at all possible, run drier vents to exhaust directly out and do not dry laundry or firewood in your basement. In summer, use a portable air conditioner or air conditioning to reduce humidity. In hot, humid weather, maintain basement windows closed. The real key to keeping basement humidity low would be to keep them well ventilated and to keep additional moisture out of the basement.
