No matter what the temperature is outside, a garden window creates a year-round growing season. It’s especially handy and attractive for growing fresh herbs or special flowering plants. A basic garden window is a bump-out unit with a shelf and features insulated glass on top and on the sides, and allows light, air and sunshine inside. The unit is designed to replace a standard size window, and most have a screen so they can be opened for fresh air. You’ll find these units sold at home centers, lumberyards, and window companies.
A contractor will charge $1,430, which includes labor and material. 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. The cost will be considerably more if the house is made of brick or it’s not a direct replacement of the same size opening, which necessitates carpentry work. If you have carpentry experience and tools, you can do the job for $975, the cost of the garden window, and save 32 percent. The cost to finish off the exterior and interior trim around the window will vary depending on the trim work required.
