  • increased energy savings - up to 12% per year
  • get up to 75-80% return on investment of the initial window replacement costs
  • boost the home's resale value by 3.5-4.5%
  • enhance comfort and aesthetics in a home
  • increase the amount of natural light flooding the rooms
  • revive the house's peace and quiet by blocking out external sounds
  • reduce condensation
  • reduce the number of units needed to heat or cool the rooms

How to calculate the costs by window frame materials?

Window frames serve as a structural base and play a crucial role in the long-lasting operation of your windows. That's why it is essential to start with choosing the frame and then move to select the right glass panes.

Below you'll find information about key types of window frame materials, their pros, cons, and average costs.

Vinyl window frames

Replacement cost per window

$230 to $650


Vinyl window frames are among the most popular and affordable materials offering high value. They're made of polyvinyl chloride and protect a house from heat and moisture. Besides, they require no painting and are available in different designs, so you may select the option that best fits the architectural layout of your house.


Vinyl window frames have a limited color range, and they are not as durable and robust as aluminum, wood, or fiberglass.

Aluminum window frames

Replacement cost per window

$175 to $420


Aluminum windows work best for those who first put frames’ strength and durability. They are lightweight, long-lasting, and resistant to wear and tear. Moreover, they are offered in various modern designs and are not prone to mold and rot.


Aluminum windows are poor for holding heat if compared to other frame materials. Without proper thermal treatment, they can affect the temperature inside, putting extra strain on the HVAC system. On top of that, aluminum is prone to corrosion.

Fiberglass window frames

Replacement cost per window

$800 to $1.250


Modern fiberglass windows are durable, strong, and easy to maintain. They're resistant to extreme temperature, can be painted in any color, and ensure excellent energy efficiency.


Fiberglass is costly compared to more affordable frame materials.

Wooden window frames

Replacement cost per window

$325 to $750


Classic wooden windows highlight the beauty of your house. They are durable, green, provide a great variety of wood species to choose from, and serve as excellent insulators. This material is best for replacing antique windows.


Wooden frames are pretty expensive in comparison to fiberglass or vinyl ones. They are subject to moisture damage and require regular maintenance.

Composite window frames

Replacement cost per window

$550 to $975


These window frames mimic wood but are left non-vulnerable to deterioration as their inner layer is covered with aluminum or vinyl. Composite frames have thermal properties and structural strength similar to natural wood. They're energy-efficient and offer long service life with little to no maintenance.


A homeowner will have to spend a pretty penny on this type of window frame. DIY installation is not possible.

How to determine installation costs by window type?

Having decided to replace your old windows, you may have numerous options to select from. Not to get confused, make sure to consider two key factors that influence the cost of new windows:

  • window design
  • window frame material

Window designs vary from single-hung, arched, jalousie, circle, and picture options to the casement, skylight, sliding, bow, egress, and bay ones, to name a few. While choosing the right type, think about the following:

  • How often are you going to open the window?
  • Where will the window be placed?
  • What function will the window perform?

Once you decide on a suitable window design, you may need to calculate approximate installation costs by window type. While the price for a simple single-hung window is quite affordable ($250 per one unit installation), the cost of a sliding window may reach $1.250 to install.

Labor costs to a window installation start from $39 per hour. The more non-standard your window type is, the higher your installation costs will be since the process will take more time and require highly qualified specialists.
