A casement window is a good choice when a room needs ventilation. It opens on its side at the turn of a crank, so it's easier to operate than lifting a traditional double-hung window. We've often installed a casement in small bathroom makeovers because the window's narrow shape takes up so little wall space but allows opening and closing with relative ease.

Casement windows are made of wood or vinyl, and they come in a variety of sizes and shapes. Like any good window, a casement closes tightly and prevents air infiltration, with the bonus feature of a foldaway handle that won't interfere with shades or blinds. You'll find them at home centers, lumberyards and window companies.

A window company will charge $678 to replace an old window with a new, good quality 2-by-4 foot wooden casement style window. That includes labor and material and assumes the new window is the same size as the existing one and it will fit into the rough opening so it's a direct replacement. If enlarging or decreasing the opening is needed, the carpentry work on the interior and exterior will increase the cost.

You can buy the unit for $365 and install it yourself, pocketing a 46 percent saving. You'll need carpentry skills and tools; it will take several hours to remove the old window and prepare the opening for the new one. Installation involves positioning and securing the new unit in the opening, finishing it with trim and molding both on the interior wall and on the exterior siding of the house.
