Garden window installation cost factors
Garden windows cost $700 to $3,000 for the unit alone, plus $300 to $1,000 for labor and installation supplies. Installing a new garden window is more complex than other window installations and takes 1 to 2 days. Replacement garden windows take less time since the hole and support structures are already there.
| Factor | Average cost |
|---|---|
| Window / materials | $700 – $3,000 |
| Labor & installation supplies | $300 – $1,000 |
| Total installed cost | $1,000 – $4,000 |
Factors that affect the cost of garden window installation include:
Labor rates:
Window installers charge $40 to $65 per hour.
Handyman rates are $50 to $80 per hour.
Contractor rates are $50 to $150 per hour when replacing windows as part of a larger home remodel project.
Size & depth – Larger and deeper garden windows cost $1,000 to $4,000 installed. Smaller, shallow windows cost $700 to $900 and are easier to install and require less support.
Location & accessibility – Upper floor installations take longer and cost more. Kitchen garden windows are usually smaller and cheaper to install.
Frame material – Aluminum and vinyl frames are cheaper than wood and fiberglass frames.
New vs. replacement – Replacing a window is cheaper since the framing, windowsill, and trim can be reused. New installation costs up to 50% more to create a new opening in the wall and add structural support.
Time of year – Seasonal deals and promotions are available in winter, which is considered off-season for window replacement.
Travel / delivery fees – Rural locations may incur added travel and delivery fees for garden windows.
Permits – Building permits cost $50 to $300 for small jobs like replacing windows.

Garden window customizations
There are many upgrades available to improve the energy efficiency and functionality of a garden window, including:
Glass panes – Single-pane windows are poorly insulated and not ideal for use in most homes. Double- and triple-pane glass improves the energy efficiency of the window.
Double-pane windows cost $400 to $2,000 installed.
Triple-pane windows cost $450 to $3,000 installed.
Glass insulation:
Low-emissivity (low-E) glass increases window prices by 10% to 15% for a thin coating of metal that reflects infrared light, keeping the heat in during the winter and out during the summer.
Argon gas filler increases the cost of a window by $30 to $40 when added to the space between panes to better insulate the window and prevent frost buildup during cold weather.
Window tinting costs $6 to $15 per square foot for a thin film of tint added to reduce heat and glare, block UV rays, and add some privacy.
Weatherstripping costs $5 to 10 per window with installation.
Fixed vs. operable:
Fixed windows are cheaper and better sealed for energy efficiency.
Operational or moving garden windows with side vents cost an average of $200 to $800 more per window, depending on the window size.
Shelf & shelf material – Adding glass shelving costs $20 to $30 for small windows and up to $300 for larger windows. Laminate or wood shelves are also available as an upgrade.
Greenhouse window cost vs. bay window
A greenhouse window is a box with a glass roof and sides that extend from the wall at 90-degree angles. Most garden or greenhouse windows are small and installed above the kitchen sink for convenience and easy clean-up.
In contrast, a bay window costs $2,000 to $6,000 for a three-sectioned window that protrudes outward at a gentle 45-degree angle, with a roof that is an extension of the house. Bay windows are much larger and often have room for a window seat.
Garden window pros and cons
Garden windows are a great place to grow plants, herbs, and vegetables without the hassles of an outdoor garden. The 4 glass panes bring in more sunlight than a standard window and provide great cross-ventilation with the side panels cranked open.
