These costs include the purchase of the window only, and professional installation costs vary depending on a variety of factors, including but not limited to the complexity of the job, the location of the property, and the materials used.

Single-Frame Casement Window

Considering a replacement single-frame casement window for your home? You should expect to pay $360 – $540 (window only, no labor and installation). This single-frame casement window works with a crank handle and holds a glass panel. The window can be hinged left or right and can open inward or outward.

Double-Frame Casement Window

Double-frame casement windows, also called French casement windows, has two windows and operates on the same design premise as French doors, which allows them to swing inward and outward together.  If you are excited about this type of window, then expect to pay $730 – $960 (window only, no labor and installation).

Egress Casement Window

An egress casement window is designed similarly to a single-frame casement window, but its primary purpose is to be used as an escape from the home in an emergency, like a fire. Having an egress casement window installed costs between $750 and $3,750 (window only). 

Egress casement windows are found at the basement ground level, and the window size must be large enough to accommodate a human being squeezing through them. 

Picture Window with Casement Flankers

A picture window with casement flankers is a combination of three windows in one area of the home: one picture window and two casement windows that “flank” each side of the picture window. If you are considering this option, the price range for a basic picture window is $760 – $1,030 (window only). A basic single-frame casement flanker costs $360 – $540 (per unit only). Remember, you’ll need two.

A picture window is a single-pane fixed window that allows for lots of light and provides a clear, unobstructed view but has no airflow (breeze). A window air conditioner could not be used in this window configuration.

24 in. x 48 in.$350 – $510
24 in. x 60 in.$420 – $440
30 in. x 36 in.$280 – $390

Larger and custom windows require a larger budget. The chart above shows the most common sizes available. In this case, size does matter for your wallet. 

Frame Materials 

The chart above reflects a 24 in. x 32 in. replacement casement window with five different frame material costs. Keep in mind that the costs in the table do not include professional installation. 

Vinyl Casement Windows

Vinyl casement windows are quite popular with homeowners because they are readily available and relatively budget-friendly.  A replacement vinyl casement window will range between $170 – $780 (window only). While vinyl is energy-efficient and does not rot or warp if it gets damaged, touch-up paint won’t work. 

Wood Casement Windows

Historically, wood has been used in the building industry for centuries for its elegance and classic look. However, with elegance comes a more expensive price tag. If you are investigating pricing to achieve that look, then consider paying $260 – $1,660 (window only). Wood requires maintenance due to peeling and warping, but it can be painted and is available in standard and custom sizes.

Aluminum Casement Windows

Aluminum wasn’t always a “go-to” window option in the past, but it has come a long way. If you are considering an aluminum casement window for its light weight and rust resistance, expect to spend between $190 and $1,180 (window only). Aluminum will corrode over time, but corrosive-resistant paint will protect any vulnerable spots. If you live in a coastal area, remember salt air is a corrosive agent and will disintegrate metal, paint, and finishes. 

Fiberglass Casement Windows

Fiberglass is a new player in the window world but an old standby in the boating world. Fiberglass is a plastic material with glass fibers embedded throughout. It does come with a higher price tag, so expect to pay in the range of $400 to $1,520 (window only). Homeowners are now choosing this material for its wood-like appearance, durability, and long lifespan. 

Composite Casement Windows

Composite is created by combining wood fibers and PVC polymers in a chemical process. The result is a strong, pliable product that is easy to maintain and is long-lasting. Composite can be “finished” to mimic the look of stone and metal materials at a fraction of the weight. The composite window’s price range is around $340 to $1,180 per unit.

Glass Coatings

Reflective Coating$230 – $500
Low-E Coating$250 – $840
Spectrally Selective Coating$350 – $500

Reflective Coating

  • The average cost of a casement window with a reflective coating is $230 – $500.
  • A thin layer of metallic or metallic oxide coating on one side of the glass to make a mirror-like appearance
  • Reduces glare and decreases heat transfer
  • Offers privacy and improves the window’s energy efficiency. 
  • This type of coating, in most circumstances, will eliminate the need for blinds or curtains. 

Low-E Coating

  • The average cost of a low-e coated window is $250 – $840.
  • Very thin layers of metallic oxide coat the glass and decrease its emissivity
  • The “E” stands for emissivity, which allows the coating material to radiate energy
  • Low-e glass retains heat during the winter and reflects the sun’s rays during the summer

Spectrally Selective Coating

  • The average cost of a spectrally selective coated casement window is $350 – $500.
  • Spectrally selective coatings are a type of Low-E coating (thin layers of metallic oxide that coat the glass and help radiate energy)
  • Used chiefly in hot climates, keeps the AC in and reduces cooling costs

Gas-Filled Windows

Argon Gas$380 – $850
Krypton Gas$530 – $1,190
Argon and krypton gas are both denser than air, so filling air spaces between window panes with these gasses slows heat transfer even further.

Argon Gas

  • The average argon gas-filled casement window cost is $380 – $850.
  • One requirement for using argon gas –  there needs to be at least one half-inch space between panes
  • Argon is cheaper than krypton gas

Krypton Gas

  • The average krypton gas-filled casement window cost is $530 – $1,190.
  • Denser than argon, it is also used to fill the spaces between panes in double or triple-pane windows
  • One requirement for using krypton gas –  there needs to be  one quarter-inch of space between panes

Insert Replacement vs. Full-Frame Replacement

A full frame replacement is when existing windows are removed down to the studs and a new window is installed. If deterioration has occurred over time, then the exterior trim,  interior trim, and siding might have to be removed. The price range for a full-frame replacement is $600 – $2,500 per window (without including the product and warranty). 

An insert replacement is when a new window is installed within the existing frame. The old sash, hardware, and covers are removed and replaced, preserving the existing interior and exterior trim. If you are looking for a less extensive installation and typically lower cost, then insert replacements range between $250 – $500 (without the product and the warranty).

Installation Cost for Replacement Casement Windows by Location

If you are a city dweller, your costs will probably be higher because of the higher cost of labor. Once on the job, installers must deal with logistical issues like parking, congestion in crowded streets, and stricter permit processes.
