1. Place the screen from your new window kit against the wall where you want to install the window and pencil in a rough outline (figure A).

2. Cut hole in drywall with a circular saw, pry out the drywall and take a look at what you're going to have to deal with in the wall (figure B). Remove insulation and any metal strapping.

3. In this case, the installation was complicated by an old stud that bisected the area and had to be removed. Plus the next stud was too far away, meaning Harrison had to construct a support frame for the window.

4. Check for existing wiring, then develop a plan to install the necessary support without disturbing the wiring.

6. Measure and cut 2x4s for the rough sill. Make support by sandwiching two 2x4s together with screws. Pre-drill angled holes through the ends where the new support will attach to existing studs. Fit support into place, check with a level and attach with screws (figure D).

7. Continue until you've created and installed a header board, side support for window and cripple studs to tie in the header at the top (figure E). Use sandwiched 2x4s for the header, but turn them so the edge faces downward to lessen the chance the header will bow under weight.

8. Check window to see if it fits the rough opening. This is a good place to take a break and finish the next day, if desired

9. Reinforce frame with more 2x4s. Next, use a long (12-inch or so) drill bit to drill holes through from the inside to the outside at each of the corners of your window opening (figure F).

10. Outside, use a 2x4 as a straight edge and connect the four dots, marking where you'll need to cut for the window (figure G).

11. Set the circular saw so it cuts through the wall, then just cut out the opening (figure H). Use the reciprocating saw to cut out the corners.

12. Fit window in place and mark the siding along the flanges. Set the circular saw just deep enough to cut through the siding and cut the rough opening for your window.

13. Check the window with a level, along the bottom and sides, to make sure it is both level and plumb. If so, secure it with roofing nails (figure I).

14. Cut new siding pieces and attach using galvanized nails. Run a bead of caulk along the new siding pieces and the window frame (figure J). Trim out the inside and you're done.
