Steps:

1. Score the window molding with a matte knife. Remove molding with a hammer and pry bar.

2. Remove the storm window from the outside of the house, followed by the windows glass pane. Unscrew and remove the frame. If the window being removed is a replacement window, take the old wooden window frame out so that the remaining gap can be framed.

3. If the existing studs of the wall are inset, you may need to insert a trimmed-to-size 2x4 as these pieces will act as nailers, filling up the gaps so a new frame can be attached.

4. Create the frame by measuring and cutting out 2x4s and nailing them into place (figure A). Once the frame is constructed, cut a sheet of plywood to cover the opening of the old window and nail from the exterior.

5. To avoid drafts, gently insert fiberglass insulation around the old opening. Keep in mind insulation needs a certain amount of airspace around its fibers in order to work properly, so do not to pack it in too tightly. Cover entire area with protective plastic to act as a vapor barrier.

Constructing the Frame and Installing Drywall

Materials:

top plates
base plates
measuring tape
studs
chop saw
framing nailer
nail gun
measuring tape
drywall
1-5/8" screws

Steps:

1. Attach top and base plates to the existing ceiling and floor. Building codes dictate studs must be 16 inches on center, meaning the center of each stud is placed 16 inches apart (figure B). As with many old houses, the walls and ceiling may not be square, so measure out each stud separately to ensure correct length and subsequent fit.

2. Use a chop saw to cut the studs to size, fit into place, level, and attach with a framing nailer to the top and base plates, shooting nails in at an angle.

3. Measure and cut the drywall to length and use screws to attach to studs. Make custom cuts as necessary to ensure a clean fit. Stagger the joints of the drywall to help strengthen it and achieve a more professional finished look.

Tip: Leave a 1/2-inch gap between the floor and the bottom of the drywall to allow for the natural expansion and contraction of the drywall through the seasons.
