Trace
the outline of the brick molding onto the siding. If you have vinyl or
metal siding, be sure to enlarge the outline to make room for the extra
trim moldings required by these types of sidings. Remove the door unit
after finishing the outline. |
4. Cut the siding along the outline, just down to but not into the sheathing, using a circular saw. Stop just short of the corners to prevent damage to the siding. Finish the cuts at the corners with a sharp wood chisel. When you're cutting, be cautious of kickback, hidden nails, and wiring. Always wear safety goggles. |

Cut 8-inch-wide strips of building paper
and slide them between the siding and sheathing at the top and sides of
the opening to shield framing members from moisture. Bend the paper around
the framing members and staple it in place. |
6. To provide an added moisture barrier, cut a piece of drip edge to fit the width of the rough opening, then slide it between the siding and the building paper at the top of the opening. Do not nail the drip edge. |
