Exhaust Fans For Basement Bathrooms - There are numerous ways to help prevent moisture damage issues in a basement. The first rule of thumb isn't a dirt basements. Although these are less common in this day in age, it's good to point out this dirt floors not only 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 in the bottom point of the ground.
With no floor drain, any water that's spilled inside can't escape. 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 may be a issue. 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 from humidity.
The easiest way to control humidity would be to exhaust water vapor produced in the home to the exterior. Indications of high humidity comprise condensation on walls, pipes or other surfaces as well a general sense of moisture from the atmosphere, dampness, and odors. Many times, the humidity is going to be brought on by exposing the basement to outside air (open windows), using wet laundry hung to dry from the basement, keeping firewood from the basement, and/or a dryer vent that exhausts indoors.
To reduce humidity, there are numerous things that a homeowner can do: install energy-efficient windows, insulate walls and cold water pipes, prefinished flooring if at all possible, run dryer vents to exhaust straight out and do not dry laundry or firewood on your basement. In summer, use a portable dehumidifier or air conditioning to reduce humidity. In warm, humid weather, maintain basement windows shut. Run the furnace fan continuously to circulate home air. The real key to maintaining basement humidity would be to keep them well ventilated and to keep extra moisture from the basement.
