Overview of Garden Window Installation
A garden window is essentially a miniature greenhouse built into a window frame and extending out from the home where it can get lots of sunshine.
Most are made up of four glass walls and a vinyl, aluminum, or wood frame.
Garden windows are especially popular above a kitchen sink or countertop where the plants growing in them can be enjoyed while working on food prep or cleanup. This is because greenhouse windows are often used for growing herbs indoors, and the kitchen is the most convenient spot to have fresh herbs ready to harvest!
Why choose a garden window?
Here are four advantages of garden windows:
Natural Light – Garden windows offer exceptional natural light, because the top and side panels are all made of glass.
Beauty – Greenhouse windows give natural beauty a place to grown. Whether you add herbs, houseplants, or decorative objects to the window, it is sure to be a mood-boosting feature of the house.
Ventilation – If you choose a garden window with operable panels, opening the sides will provide great ventilation to your home. The side panels will create a cross-breeze so that you can maximize the fresh air.
Miniature Greenhouse – Garden windows have thick glass that allows the sun to warm your home without letting inside air escape to the outdoors. Greenhouse windows help your indoor plants to thrive by providing maximum sunlight with a stable climate.

Garden Window Cost Factors
What is the overall cost for a fully-installed garden window?
Below is a list of factors that will affect the total cost of your project.
- Size – Garden windows can significantly vary in size, and the size of your window will have a big impact on the cost. As you can guess, a small garden window will be less expensive than a big one.
- Material – The frame material on your garden window will affect the cost of the project. If you choose a budget-friendly material like vinyl, the overall cost of your project will be less. If you’re going for a more elegant style and choose wood frames, be prepared for a higher price and more involved upkeep.
- Installation – The way you choose to do your garden window installation will be a big factor in the cost of the project. If you hire a local contractor, it will probably be a cheaper installation price than if you hire a high-end window company to do the installation. If you’re ambitious enough to do the installation yourself, the only installation cost will be the price of materials like trim, insulation, and power tools.
- Operable vs. Non-Operable – Garden windows that can be opened and closed will cost more than windows that are inoperable.
- Glass – Garden windows with special glass will be more expensive than the most simple units. If you prioritize eco-friendliness, make sure to get glass that is Energy Star Rated. If you live in an area with severe storms, you may be interested in impact-resistant glass.
Greenhouse Window Costs by Material
The frame material is a major factor in garden window cost. Here are installed prices for common garden windows by material.
- Wood Garden Windows – $2,800 to $4,000. Wood is the premium material for any window. Almost all wood garden windows are clad on the outside – meaning the bare wood is covered – by either vinyl or aluminum material.
- Vinyl Garden Windows – $1,900 to $3,100. Vinyl is the top choice for garden windows because it is structurally strong, offers low maintenance and is more affordable than wood.
- Aluminum Garden Windows – $1,400 to $2,600. Aluminum is lightweight and strong, but insulation is poor. An aluminum garden window is best suited to mild climates – definitely not a good fit in a cold climate where the chill might damage plants and raise your heating costs.
Some major window brands like Pella, Milgard, Harvey and Andersen’s box casement window are available, according to Home Advisor. Look at specialty brands too like Solar Innovations.
Permits, Inspection, Related Costs and Installation Time
Permits and Inspection Cost
- $0 – $200 | If you are replacing an existing window with a garden window, you do not need a permit. Make sure you’re familiar with your local regulations though, because you still need to comply with window safety regulations during a replacement project. If you are installing a garden window that involves constructing a new window opening and structural changes to the framing, you will probably need a permit, which costs around $200.
Related Costs and Installation Time
1 – 2 Days | If you are planning to install the garden window yourself, the project will probably take about two days to complete. If you are hiring a professional installer, they should complete the project within a day.
Costs of Related Projects
While you’re at it, why not take a look at some other projects related to garden windows that you can do around the house? Here is a list of some fun outdoor projects with their cost estimate:
Window Replacement – We’ve prepared cost estimates, or Business Finance News, for all major window types including single-hung, double-hung, casement, fixed windows and even skylights.
Yard Cleanup – Especially in the spring or fall, yard cleanup is a must! If you’re doing this project yourself and need to rent some tools for the job, it will probably cost you about $200. If you hire landscaping professionals to get the job done, it will probably cost $500 – $700, though big jobs can cost twice that. This includes cleanup up dead leaves and branches, trimming trees and shrubs, mowing and edging the lawn, spreading fertilizer and grass seed, cleaning gutters, etc.
An Exterior Makeover – Adding a greenhouse window is often done in conjunction with painting the exterior of the house or replacing vinyl siding. Painting averages around $1.50 per square foot of wall space. Siding starts with vinyl at about $4.50 per square foot and costs closer to $10 per square foot for genuine cedar siding. Complement the new siding with a section of stone veneer for an exceptional upgrade.
DIY or Hire a Pro?
Once you’ve decided on a garden window, the only decision left is about installation. Should you hire a professional or do it yourself? You’ll save in the neighborhood of $500 to $1,000 by our data – Window Price Guide agrees with a top installation cost of about $1,000.
Garden window installation isn’t as simple as a regular window. It requires a bit more skill, a second (or third) set of hands due to their size and weight – and it is even more important to do it correctly. A poorly installed garden window that has gaps or unsealed spots will allow water to seep in and cause damage. Air passing in and out will also cause higher energy costs.
If you have the time and patience to learn this skill, installing a garden window yourself might be the right move for you!
If you would rather get the window installed as soon as possible, without any hitches, it’s probably best to hire a professional for this one.
