12 Types Of Replacement Windows (And Costs) That Homeowners Need To Know About

Do you want to change the look of your house’s exterior and the overall feel of it? Replacing old windows might just do the trick.

When you start looking for replacement windows, you might get overwhelmed with all the available options on the market. It’s important to find the right one since windows, when well-maintained, can last for decades. I, for one, don’t want to keep looking out a window I don’t like for years. Great view or not, windows can still have an effect on it.

To make it easier for you, I’ve collected different types of replacement windows and the costs of each so you won’t have to research them one by one. Continue reading to find out which one is best suited for your home.

Double-Hung Windows

One of the most popular types of replacement windows is a double-hung. It has an upper and lower sash, which is a part of a window that moves and holds the panes. Some people prefer this traditional window style because you can raise the bottom inside sash and lower the upper outside one. This will open up the top and bottom space of the window, which can help improve air circulation by allowing warm or stale air to leave and cool air to flow in.

I recommend using it in bathrooms since you can open the top sash to let the steam out. It is also safer for homes with children and pets since you can keep the lower sash closed while still getting proper ventilation by opening the upper sash. This type is best suited for openings that are tall and narrow.

Another reason people choose this classic window is because it’s easy to clean, both the window and outside it. Most sashes of double-hung windows can open fully and tilt inward, so you can reach out and clean the exterior surface, making it suitable for the second or third floor.

The average cost of double-hung windows is around $150 to $850. It would be more expensive if you get one with sashes that lean inward.

Single-Hung Windows

Single-hung windows have the same classic and traditional look as double-hung windows, but the main difference is the operable sashes. The only movable sash is the bottom one, which can also be tilted inward, depending on the model. Similar to double-hung windows, it will still be easy to clean the exterior surface and the window itself.

The benefits of the top sash being fixed are that it can keep the cold air out and prevent water from coming in when it’s raining. This also makes it more convenient to operate and clean the window. If you think that you’ll rarely open the top window, then a single-hung is better suited for your home. This type of replacement window is also recommended for larger rooms or window openings since it will be difficult to open or tilt the top sash.

Since they only have one operable sash, expect that they will also be less expensive than double-hung windows. This type costs around $100 to $450, with the higher range for models that have swingable sashes.

Sliding Windows

Another popular type of replacement window is the sliding window. If single- and double-hung windows move vertically, this type has one or two movable panels that slide horizontally along tracks. This makes it easy to open half of a two-lite sliding window or partially open the left and right side of a three-lite sliding window. 

Sliding windows are suitable for different architectural designs with its slim and elegant look. This type is suitable for openings that are wide and short, and for halls, walkways, decks, and rooms with narrow space. It is also recommended for bathrooms and kitchens since it allows you to have control over the ventilation.

The average cost of sliding windows is between $200 to $1,000, depending on the size and configuration. It will also be more expensive if the sashes can be tilted for easier cleaning.

Casement Windows

Also called crank windows, casement windows are like doors that have a hinge on one side, left or right, which allows them to pivot outward by using a handle. This makes it easy to open and provide good ventilation. Casement windows have a simple look, which can accommodate various architectural designs. Similar to double-hung windows, it is also recommended for window openings that are tall and narrow.

Crank windows are airtight and easy to clean, with the screen located inside. This makes it a suitable option for openings above the kitchen sink, and because it is also easier to operate than double- or single-hung windows. But these are not recommended for small rooms or areas such as patios or decks.

Some people also prefer casement windows since they provide an unobstructed and maximized view, and allow much-needed natural light into the room. It is also good for home security because it can only be opened from the inside using a crank, which also doubles as a lock. This mechanism also ensures that the window doesn't open or close during a windy day. The only downside is that you cannot install a window air conditioner with this type of replacement window. 

A casement window can land you between $170 and $1,000, depending on the size and framing material. It would also be more expensive if it has two openings, with each sash being hinged on the left and right.

Awning Windows

Awning windows are similar to casement windows but the difference is that the sash is hinged at the top. It tilts out from the bottom or opens outward which prevents rain from getting inside your home. This type of replacement window is suitable for openings that are wider and short.

It has a clean and simple look that can accommodate different architectural designs. It is also airtight and easy to clean, which also goes well above the kitchen sink. Some homeowners also pair this above the door or another window to provide better ventilation in that area. It is recommended to place it high up the wall since opening the sash takes up space, so you should also prevent placing it by the patio or sidewalk. 

The cost of awning windows is almost similar to casement windows, which range from $220 to $1,000. The price will also depend on the size and framing material.

Basement Hopper Window

Similar to casement and awning windows, basement hopper windows also have a hinge but it is placed at the bottom. This type opens from the top and inward, and as the name suggests, it is usually used in basements. It helps with airflow and can be placed low on the exterior wall since it opens inward and does not obstruct passersby. 

Basement hopper windows are less expensive than the two types, costing around $50 to $350.

Picture Windows

Picture windows are fixed which means they don’t have operable sashes. These are designed to provide maximized and unobstructed views. It’s called a picture window because it frames the view similar to a picture frame. This type of replacement window is best suited for rooms that don’t require ventilation since it is sealed airtight. It only allows natural light to enter the room and can offer a beautiful view of the outdoors.

Fixed windows come in all shapes and sizes. Some even have decorative glass accents, which are customized and more expensive. For example, an octagon-shaped accent window looks great over a table in the study room. These custom-shaped windows are perfect for hard-to-reach openings with natural light, which don’t require to be opened for ventilation.

Some homeowners opt to pair this stationary window with other types such as an awning on top. This will add a style variety and provide ventilation. There are also picture windows that are paired with side panels or a different window type placed on each side.

The average cost of picture windows is between $100 and $1,200. If you go for a single rectangular regular-sized panel, expect to spend around the lower range. But for unusual shapes or larger sizes, with some almost covering the entire wall, then the cost can go way beyond this range. 

Skylight Windows

Skylight windows are similar to picture windows but are mounted in the ceiling. It is like a light fixture during the day and a picture window for stars during the night. While skylights typically require a direct connection between the roof and the ceiling to be installed, there are tubular skylights that use a reflective tube to channel light from the attic. These are usually small and suited for narrow spaces such as bathrooms and hallways. There are also skylights with operable sashes to help with ventilation. 

This type of window can cost around $150 to $1,500, which can go higher for large, customized, or will require cutting and reinforcing joints.

Glass Block Windows

Similar to the skylight window, glass block windows can be fixed or operable but what makes it different is that it doesn’t provide a view. It is made out of individual blocks of thick and break-resistant glass sealed with mortar, which can be hard to see through. Even if one cannot see the view, it still allows natural light to seep into the room. This makes it suitable for rooms that require privacy such as a bathroom. 

Glass block windows cost around $100 to $1,100, depending on the size and thickness of the block.

Bay Windows

Bay windows are composed of three windows joined at an angle, usually a larger center window and smaller side panes, which makes it project out of the home. This adds more floor space inside, which can be turned into a window seat, cozy nook, or resting area where you can read a book or drink coffee while looking at the view. From the outside, bay windows are a visual focal point that adds more style to the home's exterior.

This type is a combination of different window styles. Most often, the middle window is a fixed or picture window while the ones on the side are casement or double-hung windows to provide ventilation. But bay windows are not limited to these options as the three panes are customizable, which allows different configurations.

Compared to other replacement window types, it’s expected that bay windows will be more expensive, given that it’s like three windows in one. The average cost of this type can range between $500 to $3,500, with customizable ones costing more than $10,000. Another reason it’s more expensive is because it requires additional framing and roofing. 

Bow Windows

Similar to bay windows, bow windows also create a projection and extend outward from a home. The main difference is that it comes with more than three window panes that are curved, creating a circular extension for the room. It is also a visually appealing focal point from the outside, while inside, a comfortable seating area when provided with some cushions on the ledge. But since they don’t project outward as far as bow windows do, there will be less room. In return, you will have a bigger window area with more natural light.

For the configuration, you can also use different window styles. Most often, bow windows use custom curved windows, usually the same size, to create the curving shape. These panes can be fixed or operable if the room requires excellent ventilation.

Because bow windows use more panes which are curved and usually customized, it is more expensive than bay windows. This type can cost around $1,000 to $4,300, and can also go up to $10,000 or more when fully customized.

Custom Windows

If you have an old home that doesn’t have standard window openings or prefer a unique window style, you can always get a custom window. This is also recommended if you haven’t found any of the replacement windows above suitable for your home. Of course, these would be more expensive given that it will be built based on your choice of size, shape, and frame angle. To give you an idea, the cost of custom windows usually start at $1,000. 

Another reason it is more expensive is because you will need a professional to install it.
