A garden window is a box that protrudes from your home’s exterior wall, similar to a bay window but smaller. It has glass panes on the front, sides, and top, allowing maximum light. Homeowners typically use it as an indoor garden for their houseplants. Many top window brands offer these beautiful and functional windows to complement your interior decor. The average garden window costs $1,500–$5,000, with an average of $3,000. Read on for details about cost factors and installation.

What Are The Benefits of Garden Windows?

Garden windows are a bit like mini greenhouses for your indoor plants, so they’re sometimes called greenhouse windows. They’re typically located over the kitchen sink, but you can add one wherever you want. Here are some benefits of installing a garden window.

  • Improved aesthetics: Garden windows are attractive and allow a better outdoor view.
  • Increased natural light: You’ll benefit from the extra light a garden window allows in.
  • Indoor gardening: A garden window offers the sunniest possible spot for indoor plants, such as succulents, that need direct sunlight. You could even grow an herb garden in the kitchen.
  • Ventilation: Operable garden windows can improve indoor airflow.

What Factors Affect Garden Window Cost?

The primary factors that affect garden window costs are the window’s size, operability, and frame material.

  • Window size: Larger windows require more materials and labor, increasing costs.
  • Frame material: Aluminum, fiberglass, wood, and vinyl frames all have different price points. 
  • Fixed versus operable: Garden windows that open cost more.

Cost by Window Size

Garden windows are usually fairly large to allow for several shelves of plants. As you might expect, larger windows cost more. They also require more labor, framing, and hardware to install.

Cost by Frame Material

Replacement window costs vary based on the material used in the frame, and garden windows are no different. An aluminum garden window is the least expensive, but it’s a poor insulator and can only be used in mild climates. Fiberglass and vinyl garden windows are the most common since they’re low-maintenance and durable but still affordable. Wooden frames provide a classic look, but they’re costly and require frequent refinishing. Here are some cost ranges by frame material for a 36-by-48-inch garden window.

Cost by Fixed vs. Operable

A garden window can be made entirely of fixed panels that don’t open. If you prefer more ventilation, the garden window’s back panel can slide open. You can also use awning or casement windows, which swing open on hinges, as top or side panels. Keep in mind that windows with moving parts cost more to install and are more prone to leaks.

$600–$1,800

$900–$3,300

Operable

$900–$2,000

$1,200–$3,500

Labor Cost

Your project’s labor cost is partly determined by the installation’s difficulty. Larger, more complex windows take longer to install and thus cost more. It could be as low as $300 to install a small, fixed garden window or as high as $1,500 for a larger, operable window.

Additional Garden Window Cost Considerations

Here are some other cost considerations to keep in mind when installing a garden window.

Window Brand

Different window brands charge different amounts. Most window companies offer several choices, from budget windows to high-end options. Here are some sample garden window prices for medium-sized windows.

$800–$2,200

Milgard

$800–$2,700

Simonton

Glass Pane Type

Garden windows come in a few different glass types. You’ll get more insulation from double- and triple-paned windows, as well as windows with nonreactive gasses or special glazes in the panes. 

Most new windows are double-paned for better energy efficiency. The space between the panes prevents heat from being transferred indoors in summer and outdoors in winter, allowing your HVAC system to work more efficiently. Triple-paned windows provide even more insulation, but can substantially increase the price.
The glass can be treated to increase insulation or block harmful radiation. Low-emissivity, or low-e, coatings block both UV radiation and some infrared light wavelengths, improving insulation and protecting your home’s interior from sun damage and fading. Other spectrally selective coatings reflect certain portions of the light spectrum, blocking heat without interfering with visibility.
In energy-efficient glass, the space between window panes is typically filled with a nonreactive gas that further protects against heat transfer. This gas is most commonly argon, which is sealed between the panes and lowers the window’s thermal conductivity (or how much heat can get through). Krypton is an even more effective insulating gas, but it’s harder to find and a bit more expensive.

Here’s what some 36–by-48-inch garden windows cost based on glass type.

Customizations

You may pay more if you choose to customize some of your garden window aspects, such as opting for a nonstandard size or shape. Other options, such as frame color or window sill decorations, may also cost more. Most homeowners add wooden or glass shelves to their garden windows. These typically cost $20–$30 each.

DIY vs. Professional Garden Windows

Garden window installation is fairly complex, so it’s usually best to hire a professional window contractor.

Professional Garden Windows

If you need to cut an entirely new window hole, hiring a pro is the way to go. Cutting into your wall alters your home’s structure, and professional contractors know how to do this safely. They’ll also be able to install your new garden window securely so there are no water or air leaks. Doing it yourself risks water damage, pest infestation, or reduced home energy efficiency. If you’re not confident with your do-it-yourself (DIY) skills, it’s better to hire a window contractor and pay the labor costs.

DIY Garden Windows

Replacing an existing window with a same-sized garden window may be doable for an experienced DIYer. In addition to the actual window, you’ll need a drill, jigsaw, plywood, window well cover, and extra molding. When removing the old window and fitting the garden window to the opening, you must thoroughly seal all cracks and joins to prevent leaks. You can save on labor costs with a DIY garden window installation, but you may have to pay for costly repairs later on if you don’t complete the job correctly.


How To Hire a Pro

Take the following steps when searching for a professional window contractor.

  • Find out how long the contractor has been in business and whether they have specific experience installing garden windows.
  • Look for a pro with a regular contractor’s license, as most states don’t require contractors to have a specific license for window installation.
  • Hire only a bonded and insured contractor. 
  • Check the window company’s Better Business Bureau rating and accreditation status as well as customer reviews or references.
  • Ask your window installer about a workmanship warranty. Most new windows come with a limited manufacturer warranty.
  • Get estimates from at least three different contractors before making your choice.

Even if you hire a professional window contractor, you can save some money on garden windows with the following tips.
Smaller windows cost less for materials and labor, so consider the smallest size that’s still appealing to you. Check out our window sizing tips for more information.
Standard sizes and shapes cost less than custom options, as do plain, fixed windows with fewer decorations and moving parts.
Hire window installers in the off-season—usually winter—to minimize installation fees.
Ask the contractors if there’s anything you can do, such as preparation or cleanup, that will help reduce labor costs.
Balance up-front price with long-term quality. For example, vinyl windows typically cost less but may need replacement sooner.

Our Conclusion

Installing a garden window is a simple way to increase natural light and create an indoor gardening spot without extensive construction. Although they’re more expensive to install than regular windows, you can save some money by tackling the project in the off-season and choosing a standard size. You may be surprised at how much a garden window brightens up the kitchen or other rooms in your house.
