Basement Windows With Dryer Vents - There are several ways to help prevent moisture damage issues in a cellar. The very first rule of thumb isn't a dirt basements. Though these are less common in this day in age, it is good to point out that dirt floors not only hold a huge amount of moisture but can also give off a number of gases. When constructing a cellar, make certain that you've got a floor drain with a trap installed at the bottom point of the floor.
Without a floor drain, any water that's spilled inside cannot get out. Sump pumps are usually used where flooding due to a high water table may be a problem. Additionally, waterproof the outside of the base walls and install a perimeter drainage system. An often overlooked problem in bathrooms is moisture that comes from humidity.
The simplest way to control humidity is to exhaust water vapor produced in the house to the outside. Indications of high humidity comprise condensation on walls, pipes or other surfaces as well a general sense of moisture from the air, dampness, and odors. Often, the humidity is going to be caused by exposing the cellar to outside air (open windows), having wet laundry hung to dry from the cellar, keeping firewood from the cellar, or a drier vent that exhausts inside.
In summer, use a portable air conditioner or air conditioning to reduce humidity. In warm, humid weather, keep cellar windows shut. The key to keeping basement humidity is to keep them well ventilated and keep extra moisture out of the cellar.
