Casement window installation costs

Casement windows, also known as crank windows, cost $300 to $700 for the window alone, plus another $100 to $500 for installation labor. Casement windows are hinged at the sides and open to the left or right using a crank. Most swing outward, depending on the space available.

Factor Average cost
Materials $300 – $700
Labor $100 – $500
Total cost $400 – $1,200

Factors that affect the total cost to replace casement windows include:

  • Labor costs – Window installation labor costs $100 to $500 per window with two installers spending about one hour per window on the ground floor. Labor costs per window may be less when installing a larger number of windows at the same time.

  • Window size – Larger windows cost more to purchase and require additional crew members to install, increasing labor costs

  • Window type – Single-frame casement windows are the least expensive, while picture windows with casement flankers are the costliest since they include three windows in total.

  • Window frame material – Windows manufactured using vinyl inside and out are the cheapest, while wooden interiors with aluminum or composite exteriors are the most expensive.

  • Window location – Windows placed high up on the wall are more costly to install due to added costs for scaffolding. Windows obstructed by kitchen or bath fixtures also take longer to install, increasing labor costs.

  • Performance grade ratings – Windows with a higher Performance Grade (PG) are more costly and offer better soundproofing and protection against wind.

  • Insulating – To prevent air leaks around the windows, weather stripping costs $5 to 10 per window with professional installation.

Window types

Casement windows come in several designs, depending on the ventilation you need. Single-frame casements offer a smaller opening than double-frame casements that open from the middle with no center stile. Egress casements are designed to be large enough for a person to fit through.

Casement window cost by type
Type Average installed cost per window Details
Single-frame casement $350 – $550

One pane is set into a frame with a hinge on one side. The window uses a crank to swing out and open.

Double-frame casement $725 – $950

Also called a French casement, this style features two casement sashes set side-by-side. Each has a hinge along the outer side.

Egress casement $750 – $3,750

Designed similarly to a single frame, these are found at the basement ground level and used as an escape from the home in an emergency.

Picture window with casement flankers $700 – $1,300

A center picture window is flanked by casement windows on each side for ventilation.

Frame materials

Window frames are made from several different materials with varying costs. Vinyl windows are budget-friendly at $200 to $750 per window installed but look cheap compared to wood windows. Wood frames are more expensive at $300 to $2,000 per window installed and offer a timeless, high-end look.

Glass type and treatments

The price of a casement window varies depending on the number of glass panes, coating types, and whether they include gas insulators. The lowest prices are for single-pane glass using a less expensive frame, while the highest prices include more expensive glass, coatings, gas insulation, and more costly frame choices.

Casement window cost by glass type
Glass type Average installed cost Details
Single pane $250 – $900 With only one layer of glass or glazing, these windows are commonly used in garages or sheds.
Double-pane cost $300 – $1,100 Most common windows with two panes of glass with an insulative air pocket between the panes
Triple-pane cost $400 – $1,500 Most energy-efficient windows with two air pockets created between three panes of glass
Reflective coating $325 – $1,000 Tinted windows to decrease heat transfer and reduce glare
Low-E coating $350 – $1,300 Features a thin coating of metallic oxide to decrease the window's emissivity or energy loss
Argon gas-filled $475 – $1,350 The space between the glass panes is filled with Argon, which is 6 times denser than air.
Krypton gas-filled $625 – $1,700 The space between the glass panes is filled with Krypton, which is 12 times denser than air, or about twice as effective as Argon.

Casement window FAQs

What is a casement window?

Casement windows are hinged on one side and typically swing outward to open. They are most often operated by a hand crank, but some may be pushed open and pulled closed. Casement windows offer a wide view and good ventilation.

What is the difference between casement and sash windows?

The main difference between casement and sash windows is how they open. Sash windows slide within the frame to open vertically or horizontally. Casement windows crank to open outwards in most cases.

Are casement windows secure?

Casement windows do not offer as much security as other window types. The windows rely on hinges for security, which can rust and lose strength over time. Also, large casement egress windows allow enough room for an intruder to crawl through to access the home.

What are the disadvantages of casement windows? {#dis|

Casement windows come in a variety of designs, sizes, and materials and work well in areas where you cannot easily push a window sash up. However, they do have a few disadvantages, including:

  • They don't work well with window screens or storm windows.

  • They may not be as secure as other window types.

  • They require high-quality hardware, which increases costs.

Getting estimates from window installers

Here are some recommendations to help you choose the best window installer near you:

  • Look for licensed, bonded, and insured window installers in business for 5+ years.

  • Pick from installers with excellent online reviews on HomeGuide and Google.

  • Get multiple estimates with the same window material, glass type, and coatings for an accurate cost comparison.

  • Don't settle for the lowest-cost estimate. Also consider the quality of workmanship.

  • Request a written quote, contract, and warranty before paying a deposit.

  • Work out a payment plan with the final payment due when the work is complete.

Questions to ask

Narrow down the numerous window installers available on HomeGuide by asking these important questions:

  • How long have you been installing casement windows?

  • Do you recommend a particular window brand or material for my installation?

  • How long will the window replacement take?

  • Does the estimate include removing and disposing of my old windows?

  • What financing do you offer?

  • What warranty is included for the windows and labor?
