Factors That Affect the Cost of Window Replacement

Whether your vinyl or wood-framed windows are approaching the end of their life or you are updating the architectural look of your existing home, you will eventually need to replace your windows. While window installation is often a comprehensive and time-consuming process, finding a reliable contractor to perform the work, from assisting with the design selection to carrying out the post-installation cleanup, ensures that you will have the best replacement windows for your home.

As you compare replacement windows from various companies, it is important to take note of the differences in price points. Here are factors that influence the total cost of window replacement.

Installation Type

When homeowners decide to replace their old drafty windows, they usually come across two main types of installation: full-frame installation and retrofit installation. 

With a full-frame installation, old windows get removed completely, down to the surrounding studs that frame them. This technique allows installers to discover problems with rotted wood or moisture and come up with long-term solutions to address them. Most custom-made windows come with brand-new jambs, interior trim, and exterior brick molding. On average, a full-frame installation costs 10 to 15 percent more than a retrofit installation.

With a retrofit installation, new windows get fitted into existing frames. Jambs, which form the sides of a window frame, also remain untouched. Generally, aluminum capping is applied on the exterior to cover up rather than replace the existing brickmold. Windows that are severely damaged or too old to restore often require a complete tear-out. A retrofit window installation will not resolve most moisture-related issues like warping or rotting as it is merely a cosmetic fix.

Number of Windows

When determining the total cost of window replacement, one of the first things to consider is the number of windows you want to replace. You may need to swap out just one window or several units, depending on the age and condition of the windows. After getting a clear idea of how many windows you need to purchase, the process of budgeting becomes more straightforward.

For one to five windows, the approximate price range is $1,500 to $4,200. If you need to replace at least six to 10 windows, you may need to fork over roughly $5,000 to $8,000. However, these estimates are also directly influenced by other factors, such as the quality of materials used and the size of the units.

Materials Used

The materials you select heavily impact the quality of the final product, including its performance and longevity. The average cost of vinyl-clad windows is typically lower than the market price of aluminum and wood windows. The good news is that modern-day vinyl windows tend to be high-performance, thanks to smart manufacturing techniques that have resulted in sleek lines with easy-care finishes. Vinyl is often insulated with foam, making them extremely energy-efficient. It does not corrode and is resistant to ultraviolet light. Similar to vinyl, aluminum is strong, durable, low-maintenance, and low-cost. It is usually insulated to fend off moisture buildup and heat transfer. Another popular option on the market is fiberglass windows. The material can replicate the look of high-end products like real wood but without their high-maintenance features. Fiberglass can be painted to match the style of the home exterior, is rot-resistant, and is an excellent insulator. It can cost up to 25 percent more than conventional vinyl window replacement units.

Size of the Windows

The size of existing openings in your walls will dictate what size of windows you choose. For a small window, the price range you will be looking at is $450 to $1,500. A medium window can cost anywhere from $620 to $2,800, while a large-sized window averages from $1,150 to $2,400.

Location Within the House

The location where the window will be installed is another important factor. For example, a window in the living room will have greater square footage than a window in the bathroom. A bedroom window, on the other hand, will require an opening mechanism, whereas a window located in the hallway may be a basic inoperable picture window. When calculating how the location affects the cost of replacement windows, consider the unit in the living room to be sized as 100 percent. The kitchen window will then be about 60 percent of that, while a medium-sized bedroom window will be roughly 33 percent.

Location (House or Apartment)

Where you live can also affect the cost of window replacement. Do you need to install windows in a house you own or in an apartment you rent? A house may have more windows to replace, but an apartment may not be that accessible. If you have an apartment located on the first level, the window contractor may not charge you additional fees. If it is on the second floor or higher, the process of installing your Direct windows may impose more challenges and require specialized equipment.

Double-Pane or Triple-Pane Windows

There is no doubt that triple-pane windows will cost more than double-pane windows. You may think that triple-pane windows are strictly the better option since they are advertised as up to 20 percent more energy-efficient than double-pane units, potentially bringing you more savings in the long run. However, it largely depends on your specific area and energy needs. Some window specialists even say that double-pane windows offer the best value for your money due to their easier installation and lower cost.

When choosing your replacement windows, switch your focus from the panes and to other energy-saving characteristics of the windows, such as gas fill types, low-E coatings, and frame materials.

Window Styles

When it is time to replace your old shabby windows, you have an opportunity to choose a new product that introduces better functionality to your living space. For instance, if a window opening overlooks a deck, you can pick a window style that does not open into traffic areas like a slider that glides back and forth. For your kitchen, choose an awning window that you can crank open to catch the cool breeze and let in airflow. To improve the level of security in your home, look for Direct windows with solidly constructed locking mechanisms. 

Here is a list of some of the most popular window styles in residential spaces:

• A double-hung window also referred to as a double-sash window, has two operable sashes that slide up and down.
• An awning window has a sash attached across the top and opens outward with a crank. It is horizontal and provides wide views of the outdoors.
• A casement window hinges at the side and opens outward to the left or right. It is the classic vertical window commonly used in places where maximum ventilation is desired, such as the kitchen or bathroom.
• A picture window is a large and fixed-pane window often found in the living room. Made without glazing bars, it frames the outdoors without any obstructions.
• A sliding window, also called a gliding window, has sashes that slide back and forth rather than up and down like traditional windows. It is similar to a double-hung window, just turned on its side.
• A custom window is specially designed and built to a home’s opening. Since custom windows are not mass-produced, you have greater control over the material, hardware, color, and style.
