Spray Foam Insulation Basement Walls Mike Holmes - There are several ways to help avoid moisture damage problems in a cellar. The very first rule of thumb is no dirt basements. Although these are less prevalent in this day in age, it is good to point out that dirt flooring not only hold a huge amount of moisture but can also give off a variety 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.

With no floor drain, any water that's spilled inside can't get out. Sump pumps are usually used where flood because of a high water table might be a problem. Additionally, waterproof the outside of the foundation walls and install a perimeter drainage system. A frequently overlooked problem in basements is moisture that comes out of humidity.


The simplest way to control humidity would be to exhaust water vapor generated in the home to the outside. Indications of high humidity include condensation on windows, pipes or other surfaces as well an overall sense of moisture in the atmosphere, 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 in the cellar, storing firewood in the cellar, and/or a dryer vent that exhausts inside.

To decrease humidity, there are several things a homeowner can perform: install energy-efficient windows, insulate walls and cold water pipes, insulate floors if at all possible, run dryer vents to exhaust directly out and don't dry laundry or firewood in your cellar. In summer, use a portable air conditioner or air conditioning to decrease humidity. In warm, humid weather, maintain cellar windows shut. Run the furnace fan continuously to circulate home air. The key to maintaining basement humidity would be to keep them well ventilated and to keep additional moisture out of the cellar.
