Old Basement Renos - There are numerous ways to help avoid moisture damage problems at a basement. The very first rule of thumb isn't a dirt basements. Although these are somewhat less prevalent in this day in age, it's a good idea to point out this dirt flooring not just hold a huge amount of moisture but also can give off a number of gases. When constructing a basement, make certain that you have a floor drain using a trap installed in 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 because of a high water table may be a problem. In addition, 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 house to the exterior. Indications of high humidity comprise condensation on walls, pipes or other surfaces as well a general sense of moisture in the air, dampness, and smells. 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, keeping firewood in the basement, or a dryer vent that exhausts inside.
In hot, humid weather, keep basement windows closed. The real key to keeping basement humidity would be to keep them well ventilated and to keep extra moisture from the basement.
