Casement Window Cost for Install & Replacement

Casement window prices included in our table below reflect your options for style, size and materials when ordering windows. The cost of casement windows and installation can be compared with other types using our guides to Double-hung windows, Sliding windows and other popular windows.

Casement Window Features and Options

A casement window is a single-sash window that cranks out, and both left-opening and right-opening windows are available. The screen is on the inside of the window. Casement windows are produced for new construction and for replacement windows in good, better and best grades.

There are two ways to buy casement windows:

Standard windows are built in a range of common sizes in ½” to 1” increments and sold online and by local and national home improvement stores. Regional brands and all major window brands including Pella, Andersen, Alside, Jeld-Wen, Simonton, Marvin and Milgard produce standard casement windows in one or two materials, and color and feature options are limited. The quality is usually in the good-to-better range.

Custom windows are not built until ordered by the customer in the exact sizes required. Materials available are vinyl, fiberglass, composite, wood and vinyl-clad wood. The range of options is much larger than for standard windows, and the quality of the various custom casement window lines is in the better-to-best range. Custom windows are produced in many series by all top local and national brands. Once the windows are ordered with the help of a sales agent or a website program, the windows take four to ten weeks to build and deliver.

Here is an overview of your casement window features and options for custom-ordered windows. Again, fewer options are available for standard or “off the shelf” windows.

  • Materials – Window frames are built with vinyl ($-$$$), wood composite ($$-$$$), fiberglass ($$-$$$) several species of wood ($$-$$$$) and wood with vinyl-clad or aluminum-clad exteriors ($$$-$$$$).
  • Colors and Finishes – Vinyl and fiberglass windows may be produced in several colors depending on the manufacturer. Composite, wood finishes and clad exteriors offer many more colors. Wood windows can also be ordered unfinished or primed and then stained or painted once installed. Note, though, that if you plan to have the windows stained or painted by a professional, it will cost much more than if the process is completed at the factory. You’ll only save money if you finish the windows yourself, and it will only look good if you have excellent skills.
  • Locks and other hardware – Finishes with variations of each include white, brown, silver, gold, bronze and brass.
  • Glass, Grilles and Screens – The glass package is often called the glazing, and your options include single, double and triple pane, insulated Low-E glass, packages designed for your climate – some Energy Star rated, tinted and textured glass, tempered and shatterproof glass. Grilles come in many styles including grille placement between glass panes for easier maintenance. Screens are produced in various styles and colors.

Then range for most standard and custom casement windows is:

  • Width: 13.5” to 36”
  • Height: 17.5” to 72”

Two windows in a single frame or two moving windows and a fixed center window in a single frame can double or triple the width.

Pros and Cons of Casement Windows

Casement windows are very attractive, and they offer full-window ventilation. Because the windows crank shut, the seal is tight, energy-efficient and weatherproof. If the screen is removed, a minor hassle, the windows can be washed from inside. Some series of casement windows have semi-removable sashes that allow cleaning the outside from inside the house too. Otherwise, the windows can be opened and easily washed from outside.

For disadvantages, casement windows are more expensive than single-hung and double-hung windows of the same quality because the mechanics of a casement window must be excellent quality. In time, the cranks might need to be replaced. These windows are easier to break into too. Casement window size is limited because the entire weight of the sash must to be supported without bulking bracing.

We’ve itemized casement window costs based on the available materials and grades for the window and the cost of installation. These prices are for single windows; window systems built with a frame and two casement windows or frame, two casement windows and a center fixed window cost 75% to 150% for the window and up to 100% more for installation.

Factors that Affect Casement Window Costs

The factors covered above – frame material, size, quality and whether the window is standard or custom – are the major determinants of cost. Replacement windows cost more to install than windows in new construction. Beyond these factors, there are two factors you can control.

Window manufacturers and installers have the best pricing in early spring and late fall where winters are very cold. In milder climates, windows can be installed in winter, and that’s a good time to find deals. On the other hand, when installers are busiest, window installation prices are highest.

Who you hire to install windows will affect cost. A handyman service is the cheapest route, but if the job is done poorly, it will end up costing money to repair or replace the windows or through higher energy costs if the windows don’t fit properly. On the other hand, if a general contractor arranges installation, you will be charged a premium for the GC’s services. The best method for saving on quality windows and installation is to request estimates from several licensed window companies that know they are competing for the work.
