Replacement window costs vary widely, from $200 for a cheap DIY project all the way up to $4,000+ for a custom, professionally-installed window. It all depends on multiple factors, like the style of window (casement, double hung, slider, etc), frame material (should you go with cheap vinyl or more expensive fiberglass?), and labor costs (DIY or professional).

If you want to replace or add windows to your home, single hung windows are a popular choice. But are they the right fit for every room in your house?

When you think of the archetypal window, the image that comes to mind is probably the double-hung window. These windows are the most popular in America because they're simple, offer great airflow, and go with virtually any style, from classic to contemporary.
