1. Draw lines down the exterior wall, directly below the edges of the window to have a guide to cut by. Start demolition from the outside in order to check for any electrical wiring or other obstructions.


2. If cutting through vinyl siding, place the circular saw blade on backwards to prevent excessive damage. Cut through the siding, following the lines drawn on the wall.


3. Remove the vinyl siding and any insulation or wood siding underneath.

4. Once the studs are exposed, check for any electrical wiring or other obstructions.


5. Remove the window casing and window from the wall using the prybar and hammer.


6. Using a reciprocating saw, cut along the studs all the way down to the floor.


7. Remove the remaining wall.

8. Measure dimensions of the opening and cut 2x4s to build a frame that will hold the door. Nail all the frame pieces with a nail gun into the sides of the opening.

11. Put a frame up on the outside as well, using materials to match your house.

12. If necessary, build steps to lead up to the door. Measure the step tread in order to figure out the spacing of the pre-cut stringers. Once determined, nail the stringers into the wall for support.
