If you want fresh herbs and flowering plants all year long, and want to replace a window, consider a garden window. It’s a bump-out unit with a shelf and insulated glass top and sides that allow light, air and sunshine inside. The units are designed to replace a standard size window, and most are designed with a screen so they can be opened for fresh air.

You’ll find these units at home centers, lumberyards and window companies. When you’re shopping for a greenhouse window have a good idea of how much shelf space you’ll need. Some units have shelves that can be removed or adjusted to different heights, so determine the amount of display space you’ll need and you’ll be able to find a window that’s perfect for your room.

To remove an existing window in a house with vinyl, wood or aluminum siding and replace it with a 3-foot by 4-foot vinyl garden window, a contractor will charge $1,430, which includes labor and material. The cost will be considerably more if it’s a brick house. If you have carpentry experience and tools, you can do the job for $975, the cost of the garden window, and save 31 percent. The cost to finish off the exterior and interior trim around the window, which will vary depending on what’s there, is not included.

The carpentry involved in the project includes removing the old window without damaging the interior walls and exterior siding, and squaring up and framing the opening for the new unit. While the installation is straightforward, more finish carpentry skills are needed to install interior woodwork and trim out the siding.
