Types of Windows to Choose From

The type of windows you choose also impacts the final cost. Here are the different types of windows, their prices, and their benefits and disadvantages.


Casement Windows

Casement windows open outward and have large glass panes that provide plenty of light.

These windows are also ideal for homeowners who prefer energy-efficient windows. The only downside is the price — casement windows typically cost double, compared to affordable options such as double-hung windows.

Awning Windows

Awning windows also open outward and they open with the help of a crank. Awning windows are versatile and can be installed anywhere, even above the doors. These windows are also less expensive than many other window types.

Picture Windows

Picture windows don’t open and consist of large glass panes. They’re commonly installed on the center portion of a wall to provide a grand view. Picture windows are recommended for higher-story homes and rooms.

Keep in mind, these windows don’t offer the best energy efficiency. They’re also one of the priciest window types.

Double-Hung and Single-Hung Windows

These are the most common types of windows.

The only difference between the two is the sash — single-hung windows have one movable sash while double-hung windows have two. These windows look great in all buildings and homes and are easy to clean and maintain.

These are also some of the most affordable window types. The only downside is they don’t offer the best energy efficiency.

Jalousie Windows

Jalousie windows are the most inexpensive option. These windows consist of glass slats with metal clips and are easy to open and close.

While these windows are cheap, they’re not ideal for colder climates. They provide maximum airflow even when they’re closed, which will make your home extremely cold. They also offer less security.

They say the eyes are the windows to the soul, so are your windows the eyes of your home? Even if they aren’t, they play a powerful role in your curb appeal as well as your energy efficiency.

When those windows break, develop frame problems, or become outdated, it takes away from both the look and function of your home. You want to fix the problem as soon as possible, but is it in the budget?

The only way to find out is to get to know how much window repair and replacement windows cost in Denver, CO.

Common Types of Windows in Denver

Your window replacement and repair costs depend on many factors. The top one is the type of window you have. To know what you’re looking for, brush up on your terminology and learn about these popular types of windows.

Single-Hung Windows

You may not know it, but single-hung windows are the classic types of windows you often see in homes. These windows have a top pane and a bottom pane. The top pane is fixed in place and the bottom pane can move up and down to open and close the window.

The term “single-hung” comes from the fact that a single pane of the window has a track that allows it to move.

Double-Hung Windows

Single-hung and double-hung windows often look similar, but there is one difference. In a double-hung window, both panes can move up and down. This gives you more freedom because you can open the top or the bottom of the window.

Sliding Windows

The term seems a bit strange because most windows open by sliding. A true “sliding window,” though, is one in which the panes slide to the sides to open the window.

These windows could be similar to a single-pane or double-pane window turned to the side. In many cases, though, there are movable panes in the middle and fixed panes on the sides. You open the window by sliding the middle panes to the sides, so it opens in the center.

Casement Windows

Single-hung, double-hung, and sliding windows are all rather low-profile. In other words, they take up the same amount of space whether they’re open or closed. Casement windows are unique.

These types of windows are hinged on one side and they open outward like a door. Most have a crank at the bottom you can use to open and close the window as much as you choose.

Stationary Window

The windows above have all been unique because they open in different ways. What about windows that don’t open at all?

These are called stationary windows, and they can be economic ways to boost your natural light while maintaining a more solid seal.

Bay Windows

Bay windows are special because of their unique shape. These windows have three sides that create an arc-like shape.

There is a window in the middle with an angled window on each side. Altogether, a bay window is shaped like the top half of a hexagon. You’ll often see these windows along with a nook that protrudes from a house.

How Much Does Window Repair Cost in Denver, CO?

For some types of window damage, you don’t need a full replacement. Repair technicians may be able to fix problems like defects in the window frame or a broken pane.

In Denver, typical repairs range from $150 to $525. Of course, this will depend on the type of repair you need, because some are pricier than others.

How Much Do Replacement Windows Cost in Denver, CO?

While repairs sometimes work, there are other situations when you need to replace your window altogether. As you might expect, this will have a higher price tag because you’re getting a full new window.

In Denver, the average cost is around $650 per window. The range, however, spans from $200 up to $1800.

Why such a large variation? It all comes down to your needs and the choices you make along the way.

Factors That Affect Your Window Replacement Cost

There are multiple reasons your window replacement might cost far more or less than your neighbor’s replacement. All the factors below will play a part in your bill.

Window Quality

As you may expect, a higher-quality window will cost more. That will raise the price of your total project.

In some cases, though, high-quality windows can save you money too. The right ones can lower your energy bills and increase your home’s value. They might not be as expensive as they seem when you take those advantages into account.

Type of Window

All the window types we explained above have their own price points. For example, a large bay window will cost more to replace than a standard single-hung window. Double-hung windows tend to cost more than single-hung windows too.

In addition to their shape and mobility, windows differ in their frames. Some frames will make the window more expensive depending on the material they use, from wood to vinyl.

Installation Contractor

Your installation specialist is a critical part of your window replacement. You could splurge on a great replacement window but if the contractor doesn’t install it correctly, you’ll lose out on the security, energy efficiency, and other advantages it offers.

Your installer will also affect the price, though. If you hire a window contractor who has specialized skills, advanced equipment, and extensive experience, you can expect to pay more.


There are certain window sizes that are standardized and mass-produced. If your home’s window opening doesn’t fit any standard size, though, you’ll need to order a custom window. As you can expect, that will raise your price.

It’s important not to compromise on window size or say “good enough,” though. If a standard window is even half an inch too small, it makes it difficult or impossible for your installer to create a strong seal. Your attempt to save money could leave you with a drafty home for years.
