Bay Window Cost

How Much Does a Bay Window Cost?

	Low Price: Window Starts $800-$2,000; Can Run $2,500-$7,000
	Average Price: Usually Runs $1,500-$8,000 Installed

A bay or bow window lets in daylight and creates the illusion of a larger room. Both styles protrude outward from the exterior wall, adding a unique architecture feature, and many have a small window seat indoors, creating a cozy place to admire the view. A bay or bow window can be an esthetically pleasing way to replace a small window with a larger, more panoramic one without appearing out of place on an older home.

Typical costs:

• The cost for just the bay or bow window (without installation) starts around $800-$2,000 for a standard version but can run $2,500-$7,000 for a larger or a custom model. The price will depend on the size and the materials used. Vinyl is long-lasting and more economical, but not everyone likes the look of vinyl as compared to the more traditional wood.
• With professional installation the average cost can jump to anywhere $1,500-$8,000, depending on the cost of the window and the complexity of the installation. It usually costs more if the installer has to create an opening or enlarge the opening from the pervious window. A New Jersey homeowner[1] received quotes ranging from $2,800-$3,700 for complete installation of a bay window.

What should be included:

• A bay window has three windows fastened together ("mulled") at the factory, usually at an angle of either 30 or 45 degrees. The center window is similar to a small picture window, and the two side windows will usually open for ventilation. A bow window has four or more windows -- five is typical -- creating a more circular appearance than the somewhat boxy bay window. A window manufacturer illustrates[2] the two types.
• TurtleSoft.com estimates that installation[3] of an 8-foot bay window takes two skilled workers an average of 1.5-2 hours, with a little help from an unskilled worker. Installation requires cutting (or enlarging) an opening, and suspending the window from the wall so it's structurally sound. Most bay or bow windows are made of wood or vinyl, come with insulated double-pane windows, and standard widths range from 3-1/2 to 10-1/2 feet. ThisOldHouse.com provides an overview[4] of the various options and describes the installation of a second-story bay window[5] .

• Adding a copper roof on a bay window looks sharp but can cost another $1,500-$3,500 or more.
• Pre-drawn plans[6] for a bay window addition are available online for $40-$50.

• Major manufacturers of bay or boy windows include Andersen[7] , Jeld-Wen, Milgard[8] and Pella. These companies provide referrals to local suppliers or dealers.
• Generally, installing a bay or bow window is not considered an average do-it-yourself project, and most experts recommend hiring someone with experience installing bay windows, especially if the existing window opening needs to be enlarged or if a new opening must be created. If installation is not included in your purchase price, ask for contractor referrals from friends or family, or at the local hardware store.
