Windows play a crucial role in any home’s functionality, weather protection, and energy efficiency. But over time, they may require replacement due to various factors like drafts, leaks, sudden hikes in energy bills, loud exterior noises, structural issues, cracked or broken panes, and more. One may also wish to upgrade to more efficient windows for enhanced insulation, security, and aesthetics. The cost of window replacement varies depending on the frame and window types chosen.

Cost of an average window replacement
So, one might ask, “How much does the average window replacement cost?”. The average cost to replace windows is around $700 per unit, but it can fluctuate significantly. Several factors, such as the type of window frame chosen, the glass material, the specific style of the window, and any additional features or customization, influence the variation. Additionally, geographic location, the complexity of the installation process, and the selected brand can further impact the overall cost.

Window replacement estimates by frame material

• Fiberglass
  Fiberglass window frames are known for their durability and energy efficiency. They are highly insulating, designed to withstand extreme weather conditions, and are usually immune to warping, rotting, and expanding. They are slightly costlier than the other types of frame materials, but they are relatively low-maintenance and eco-friendly. The average range of fiberglass per window is from $700 to $1,400.
• Composite
  Composite window frames blend materials like polyvinyl chloride polymers, wood, and aluminum. This results in frames that combine the strengths of different materials and are relatively resistant to weather, decay, and insects. Composite windows mimic the look of wood and offer a versatile aesthetic appeal. The window replacement cost of composite frames ranges from $400 to $1,500.
• Wood
  Wood window frames add a timeless charm to any home and instantly enhance the overall feel of the space with their natural beauty. Wood frames are customizable but require consistent maintenance to prevent warping, rotting, and damage due to insects. The cost of wood frames varies widely, ranging from $250 to $1,800 per window, offering flexibility in budget considerations.
• Vinyl
  Vinyl window frames are known for their sturdiness and affordability. They require virtually no maintenance. They are resistant to moisture and insects, and they also provide decent insulation. They are among the most cost-effective window frames. The replacement cost with vinyl frames typically ranges between $150 and $900, with an average of about $375 per window.
• Aluminum
  Aluminum window frames are known for their cost-effectiveness, low maintenance, and strength. They are lightweight and resistant to corrosion. Aluminum frames are better suited for large windows and have various modern designs. However, they lack natural insulation and may require additional insulation barriers within the frame. They are also less energy-efficient than other materials. The cost of aluminum frames ranges from $80 to $800 per window, making them a practical choice for those prioritizing affordability.
