Casement Window Replacement Cost

Your windows and doors are the main areas that allow heat and cold to come in and out of your home. If the house isn’t well-insulated, this will drive up your energy bill.

Old windows don’t provide much energy efficiency, which is one of the main reasons homeowners look for window replacements. You want your new windows to perform well AND look stylish, right? 

Casement window replacement costs generally won’t stretch your budget more than other windows, and they have some great features and advantages.

Casement Window Replacement Features

Casement windows are extremely popular – both in newly built homes, and as window replacements in older homes. But there are all kinds of window styles on the market, each of them with their own perks. What makes casement replacement windows stand out from the crowd? 

Window design: Casement windows have a large pane of glass with no obstruction in the middle of the window, like picture windows. Unlike picture windows, though, casement windows can be opened for ventilation. They also allow for escape in case of emergencies, so they double up as egress windows.

Complex, high-end window styles, like bay windows, make use of three or more casement windows arranged in a box shape.

Casement sash opening: Casement window sashes open outwards like a door, with hinges on one side of the window frame. They can also open from the top in an awning style, or from the bottom in a hopper style.  

Casement windows use a crank handle to open, and a casement stay that allows them to remain in a fixed position. While this kind of opening allows for great ventilation, it also means that the weight of the sash can bend the hinges out of shape over time.

Position: Casement windows open outwards, so they’re not suitable for window spaces that look out onto a patio or walkway. You should also consider which side of your casement window should be hinged, so you can open the window fairly wide without channeling too much wind into the room.

Ventilation: When a casement window is open, it acts as a “windcatcher”, that directs breezes into your home. This allows for a very pleasant environment if you like lots of fresh air. However, this won’t work too well in high winds – there’s a risk of damaging the window frame and hinges from excessive pressure.

Insulation: Unlike double-hung windows, which slide on a track and risk letting air through, casement windows lock tightly into the frame. A tighter seal on your window means you get a higher energy efficiency rating.

Window treatments: Casement windows aren’t suitable for some types of curtains and blinds. The crank handle could get in the way, or the arrangement could be blown around excessively when the window is open. Consider carefully whether your favorite window and décor styling will fit on new casement windows. 

Pros and Cons of Casement Window Replacements

Casement windows are a popular option, but they might not work in every home. Weigh up the pros and cons carefully before signing on the dotted line!


  • Casement windows are extremely energy efficient.
  • They open very wide and allow for excellent airflow.
  • Casement windows suit contemporary-style homes well.
  • They are relatively affordable – unless they are used in high-end window styles, like bay windows.
  • Hinged casement windows are much easier to open than single or double-hung windows.
  • They are very secure – an intruder would have to break the glass to gain entry, as opposed to forcing open the sash.


  • Casement window replacements are large and will take the brunt of high winds – they’re not suitable for areas that get lots of storms.
  • They won’t fit next to walkways or patios, as they will intrude into the space.
  • It’s more difficult to add certain shutters, screens or curtain treatments to casement windows – pick your décor wisely.

Casement Replacement Window Costs

Casement windows are available in various materials. As they are usually exterior facing, they have to be secure, attractive, and have top-notch weather sealing properties.

These factors can push up the prices – but you can expect a good return on investment with lower energy bills and higher property value.

Here is an overview of various types of windows and their basic material costs.

Labor costs are around $250 depending on your area, and the scope of the replacement project. Don’t forget the cost to remove and dispose of the existing window – it will be around $40.

Type of Window Full Frame Replacement Cost
Casement $245 - $750
Double-hung $300 - $700
Picture $385 - $800
Sliding $450 - $1,300


Casement window replacement costs are offset by their superior energy efficiency. When they are fitted well, there is very little chance of escaping air.  

Casement windows have great ventilation, and they look modern and stylish, but you’ll have to consider their positioning in your home. They are not suitable for every window space.
