Installing a Garden Window

Gardening, Kitchen, Punch!, Windows & Doors December 30, 2009 Sonia


Just because the temperatures are turning colder, there’s no reason to say farewell to your garden—just move it indoors. Adding a bumpout Garden Window to your home allows you to grow herbs and plants throughout the year. Not a gardener? Don’t worry, these cozy windows make the perfect napping area for the family cat or a showpieces site for displaying collectibles.


One of the best places to locate a Garden Window is in a kitchen. Oftentimes builders install a hard-to-reach double hung window over a kitchen sink. Because they can be difficult to operate in that location, homeowners don’t gain ventilation in the kitchen area. With operating casement sidelites that easily crank open to allow in air the Garden Window solves that problem.


Simonton Windows offers a Garden Window that’s easy to install as a do-it-yourself project and adds value to the home.



Measure Twice—Order Once

This simple installation project starts by gaining measurements of the rough opening so that you can order the Garden Window. If you’re replacing the existing window, take off the window’s casing trim. Then measure the top, middle and bottom of the opening from side-to-side and top-to-bottom. Also, measure the opening diagonally to ensure the area is square.


For a Garden Window, deduct 1/2″ in width and 1/2″h in height when ordering the unit. This will ensure a properly sized unit to fit your area. Next, measure the finished surfaces from the exterior to the interior wall using a combination square. You want to determine the maximum jamb depth to make sure the proper unit is ordered.

You’ll want t o note in your order if the window is for a new construction or a remodeling project. If you are ordering for a new construction option, flashing flanges come standard. If you’re installing this unit as a replacement unit, the flashing flanges may be ordered as an option if you believe you’ll need them for the project.


When placing the order with Simonton, make certain to specify if you want a white, oak or birch finish on the interior of the unit. You may also order an optional insulated sea board to place at the bottom of the unit which will help increase the R value of the window for cold climates. Instructions will arrive with the sat board for easy assembly and installation.



Inspecting the Window

After placing the window order and receiving the unit, carefully inspect the Garden Window. If you’re installing this unit as a replacement window, make sure to do this before removing the existing window. Double-check the dimensions of the unit to make sure they match up accurately with the dimensions ordered for the window.


Make certain you have received 12 screws with screw covers. You should also receive two brackets and a tempered glass shelf for the window. If you ordered the flashing flange, make sure you received the trim piece that will snap in at the top of the exterior of the unit to help prevent water infiltration.


If the checklist for your Garden Window comes up good, then move forwards and remove the existing window right down to the rough opening caused by rot before fitting the new window in place.


Dry Fitting the Unit

From the outside of the home, place a sturdy jack stand directly below the exterior of the rough opening. Make sure the stand is level with the bottom sill of the rough opening so that it can support the unit during installation.


Have two people dry fit the window into the opening, using the jack stand to help steady the unit. While one person remains outside, have another person go inside. Double-check to make sure the operable sidelites are fully operational and can easily open while the unit is dry fitted into the home.
