Common wood types include oak, mahogany, walnut, ash, and cedar.^[8]

Aluminum

Aluminum windows are strong and lightweight, making them suitable for large windows. However, they are not as energy-efficient as other materials. The average cost for aluminum windows is $501 per window.^[1]

• Pros: Strong, lightweight, and resistant to bending and warping.
• Cons: Not very energy-efficient, prone to corrosion, and less aesthetically pleasing.

Fiberglass

Fiberglass windows are durable, energy-efficient, and low-maintenance but tend to be more expensive. Expect to pay around $529 per window for fiberglass.^[1]

• Pros: Energy-efficient, customizable, low-maintenance, and long-lasting.
• Cons: Higher cost compared to vinyl and aluminum, and fewer color and design options.

Composite

Composite windows blend wood fibers and polymers for added durability and weather resistance. Composite windows are low-maintenance and energy-efficient, but quality can vary by manufacturer. Composite windows cost around $655 per window. ^[1]

• Pros: Durable, energy-efficient, low-maintenance, and resemble the look of wood.
• Cons: Higher price, and quality varies by manufacturer.

Window Styles and Their Costs

The style of window also significantly impacts the overall cost. Here are some common window styles and their average prices:

• Double-Hung Windows: These windows have two sashes that slide vertically, offering good ventilation and easy cleaning. Double-hung windows typically cost between $150 and $650 per window.^[6]
• Single-Hung Windows: Similar to double-hung windows, but only the bottom sash is operable. Single-hung windows range from $100 to $400.^[6]
• Casement Windows: Hinged on the side and crank open outward, providing excellent ventilation and a tight seal when closed. Casement windows cost from $150 to $1,000.^[6]
• Awning Windows: Hinged at the top and open outward, allowing ventilation even during light rain. Awning windows average around $429 per window.^[1]
• Sliding Windows: Feature one or more sashes that slide horizontally. Sliding windows range from $150-$800.^[6]
• Picture Windows: Fixed windows that do not open, designed to provide a clear view and maximize natural light. Picture windows cost from $65-$700.^[6]
• Bay Windows: Consist of three or more windows that project outward from the wall, creating a bay inside the room. Bay windows are more expensive, typically costing between $3,000 and $5,000.^[4]

Energy-Efficient Windows: Features and Costs

Investing in energy-efficient windows can significantly reduce your energy bills and improve your home's comfort. Key features that contribute to energy efficiency include:

• Double-Pane and Triple-Pane Glass: Double-pane windows have two layers of glass with an insulating space between them, while triple-pane windows have three layers. Triple-pane windows offer superior insulation and noise reduction but cost more. Double-pane windows typically cost between $150 and $1,290, while triple-pane windows range from $400 to $3,540.^[9] According to some sources, triple-pane windows cost 10-15% more than double-pane windows.^[16]
• Low-E Coatings: Low-emissivity (Low-E) coatings are microscopically thin, transparent coatings that reduce heat transfer through the glass. Low-E glass can add $150 to $300 per window.^[14] The cost for Low-E glass installations ranges from $350 to $850 per window.^[25]
• Gas Fills: Filling the space between the glass panes with argon or krypton gas further insulates the window. Gas-filled glass can add $200 to $350 per window.^[14]

Replacing single-pane windows with ENERGY STAR-certified windows can save you $101–$583 per year in energy costs.^[9]

Installation Costs and Considerations

Installation costs can vary depending on the complexity of the job, the type of window, and your location. Here are some factors to consider:

• Labor Costs: Professional installation typically costs between $70 and $150 per window.^[3] Some contractors charge an hourly rate, which can range from $55 to $65.^[8]
• Full Frame vs. Insert Installation: Full frame replacements, which involve removing the entire window unit, are more expensive than insert installations, which only replace the window sash and frame.
• Home Age and Condition: Older homes may have non-standard window sizes or structural issues that require more labor and increase costs.
• Permits: You may need a permit to replace your windows, which can cost $50 to $100 per window.^[7]
• Accessibility: Windows on upper floors or in hard-to-reach areas can increase labor costs.^[7]

It's important to get multiple quotes from different contractors to ensure you're getting a fair price.^{[2, 8]}
