New and Replacement Basement Window Considerations
When a window becomes a hinderance to a basement rather than a welcome source of light, it may be time to consider its replacement.

Basement windows are a welcome source of light within an otherwise dark space. But when a basement window becomes cracked or rotted as a result of years of use, it may be necessary to consider replacing the unit.
Functionality is important when choosing a new basement window. Make sure that windows are easily cleaned and lock out exterior moisture, a common problem in basements. You may also want to consider triple-paned windows, a more energy efficient window choice that will reduce the cost of heating and air conditioning a basement.
Once you have chosen a window that suits your needs, it is crucial that you measure an exact fit for your basement window space. A poorly fitted window will allow for water seepage and air drafts – two qualities that don't agree with any living space. If there are any gaps around the edges of the basement window, fill the space with caulking.
Window insulation is also important to the installation of a basement window. Insulation will reduce the loss of heat that is common through basement windows, making the space more energy efficient.
If there is a steel window well on your home's exterior, you may want to consider replacing it with a plastic window well that is less sensitive to temperature elements. This will also help the productivity of your replacement window.
