In this guide to purchasing casement windows, we’ll cover:
Replacing a casement window yourself might be tempting, but in most cases, it’s well worth the money to have a professional complete the work for you. This is especially true since the average price to replace a casement window is around $750, which isn’t terribly expensive. Most homeowners pay between $450 and $1,200 for this service.
In this guide to choosing and installing casement windows, we’ll discuss what casement windows are, the pros and cons of this style of window, and average prices. We’ll also go over cost factors that can affect your price, how to save money in the process, and more.
Casement windows are a style of operable windows. In most cases, the window sash is taller than it is wide. The sash is hinged on the side and opens like a book. Most casement windows have a crank inside that allows you to open and close the sash.
Casement windows can be installed as single windows, but they’re more often seen in groups of two, three, four, or more. They are components of bay windows and bow windows in many cases.
Casement windows are most common in living rooms, although they can technically be installed in any room in your home.
Double-hung windows and casement windows are two of the most common styles of windows in homes in the U.S., but it’s easy to tell the difference between the two.
Double-hung windows have two sashes — a top sash and a bottom sash — that slide independently of one another and often tilt inward for easy cleaning. Casement windows have just one sash that is hinged on the side and opens outward like a book.

Casement windows are one of the most popular window types and for good reason. They provide quite a few benefits over other styles, which we’ll explain briefly below.
Of course, casement windows aren’t perfect, and there are some downsides to installing them in your home. We’ll briefly discuss the primary drawbacks of this type of window below.
As mentioned above, the average cost to replace a casement window is around $750, which is higher than the overall average replacement cost of $600. Most property owners spend between $450 and $1,200 to replace a single casement window, and prices can easily fall outside of this range.
The number of casement windows you’re replacing, the window frame material, glass type, and hardware options can all affect your costs and bring your total well over $1,200. The size of the window also plays an important role in your total.
The price range for casement windows is so wide in part because the material costs can vary quite a lot. Below, we’ll outline the most significant factors that affect your material prices.
The other significant portion of the replacement price for a casement window is for labor. Just like with the material charges, labor costs can vary based on a few factors. We’ll discuss these briefly below.
As mentioned above, casement window styles are generally composed of multiples in a set. The number you choose dictates how costly your window or set of windows will be. We’ll include some average prices for the different styles in the table below.
Type of Casement Window | Typical Replacement Price (Per Window) |
Single Casement Window | $750 |
Double Casement Window | $1,300 |
Triple Casement Window | $2,000 |
Quadruple Casement Window | $2,500 |
Double Casement Window with Picture Window in the Middle | $2,000 |
Casement windows don’t come in as many standard sizes as most others, as the hinges and hardware often limit how wide they can be. However, they still come in a few options. We’ll provide some average pricing by size below.
Size of Casement Window | Typical Replacement Price (Per Window) |
19” x 16” | $450 |
19” x 29” | $500 |

38” x 78” | $1,200 |
When it comes to buying casement windows, you can purchase them from a window manufacturer — like Andersen or Pella — or from a home improvement store or major retailers like Home Depot or Lowe’s. Each comes with some pros and cons.
Buying from a manufacturer costs a bit more, on average, but you more often get higher-quality windows. Manufacturers often couple installation with the window, so you typically get a better warranty. You can also order custom sizes, shapes, and colors. Going with a manufacturer is the best route in most cases.
Buying from a retailer means you can choose to install your window as a DIY project. You also won’t have to wait for the construction process or for delivery, which can take weeks. You will also have more choices in terms of brands and styles.
The brand of the casement window you choose to install in your home will affect the overall quality of the product, the durability, and, most importantly, the coverage included. Therefore, brands can swing the price up or down, irrespective of other window options. We’ll include some average prices for the most popular brands below.
Brand of Casement Window | Typical Replacement Price (Per Window) |
American Craftsman | $450 |
Andersen | $850 |
Certainteed | $1,000 |
Harvey | $1,200 |
Hy-Lite | $800 |
Jeld-Wen | $750 |
Marvin | $900 |
Milgard | $950 |
Pella | $800 |
Reliabilt | $650 |
Simonton | $800 |
Replacing casement windows can get quite expensive, especially if you’re replacing multiple windows at once. Thankfully, there are a few things you can do to keep your expenditure to a minimum.
First, you can choose budget-friendly window materials. It’s best to balance efficiency and up-front cost for the best long-term results. Some of these options include:
Another way to save when replacing casement windows is to look for optimal times to buy. This can mean waiting until the off-season or waiting for holidays when some manufacturers offer discounts and deals on replacement.
Finally, you can save some money per window by replacing all of the windows in your home at once. You will, of course, pay more up-front, but most installers will give a discount on multi-window replacement projects. Doing this will also have the most positive effect on your home’s efficiency, so you could enjoy more savings on your energy bills as well.
Calculating your replacement cost and how much you need to budget for your window project overall can be a little intimidating. The formula below should help guide you through the process and you can customize it for your specific window needs.
(Frame Cost + Glass Cost + Labor Costs + Glass Coatings + Window Accessories) x Brand Coefficient = Total Casement Window Replacement Cost
Total Casement Window Replacement Cost (from above) x 0.95 (discount factor) x number of windows in your home = Total Cost to Replace All Home Windows At Once
If we assume you’re replacing an average-sized casement window, forego add-ons, and want to go with a Milgard window, your calculation should look something like this:
($450 + $150 + $150 + $0 + $0) = $750 x 1.3 = $975 for a single Milgard casement window
($450 + $150 + $150 + $0 + $0) = $750 x 1.3 = $975 x 0.95 x 10 windows = $9,262.50 for 10 windows
Casement windows are a bit on the expensive side, not only because they tend to be bigger than other common styles but also because they have more complex hardware. They require high-quality cranks, gears, and hinges to support the full weight of the window sash.
For comparison, the average casement window replacement costs around $750, while a double-hung costs around $600, and a single-hung averages around $450.
The installation process for a casement window is similar to that of other styles. About half the time — around a half-hour to an hour — will be spent removing the old window, and an additional half-hour to an hour will be spent installing the new window.
This process can be complicated by installation on the second floor or by the need to reframe the window opening for a different size casement window. In both of these cases, the process can take much longer.
You should also keep in mind that ordering casement windows from a manufacturer can lead to weeks of delay due to the manufacturing process and delivery.
Casement windows are somewhat secure, but they don’t offer as much security as most other window types. Casement windows rely on hinges and gears for security, and these components can rust and lose strength with age.
Most other styles of window — including double-hung windows, single-hung windows, awning windows and picture windows, or fixed windows — offer a higher level of security.
