subject: Replacing An Existing Window With Garden Windows [print this page] Garden windows are a pleasant alternative to an old basic window. A real plus to garden windows is that they come pre-assembled. Each has a headboard, side joints, and a seat board. Before installing, remove the existing window and its sash.
Cut some 2" by 4" studs to the height of the bottom edge of the widow unit, and put side. Next, place the inner edge of the garden windows on the sill, and tilt the unit in until it's at least halfway in; this way the sill will support the unit's weight. Now use the studs to support the garden windows as you move the unit out to its proper position.
Use a level to get the windows level and plumb, and hold the unit with shims. Then use 10d or 12d finish nails to gently secure the unit. On the outside, set one of the braces under the unit with the long leg against the wall, and drill holes into the wall. You want to hit the wall stud - if it's a wooden wall. If you have to shift the brace over a bit, try to insure that it'll be symmetrical with the other braces. Depending on the size of the unit, you may have several braces to install. Attach the brace to the wall and then to the unit's underside, and then move on to the next one.
After the braces are in place, run sealant around the exterior edge and remove the temporary stud support. Then slip insulation into the spaces around the unit and install the trim work on the sides. You then fill the screw holes with wood putty, sand them down, and paint with stain or an oil based paint.
