In Part 1 of this how-to, you demolished a set of windows to create an entryway to an outdoor area such as a porch or patio. Now, you are ready to remove the surrounding wall studs, install the new door, and finish the exterior in the project area. This phase of the project takes one weekend and costs between $1,000 and $2,500.
You will need:
Step 1: Remove the housing wrap to determine where the wall sheeting ends. If this stops at your floor, make vertical cuts in the middle of it with the reciprocating saw. Cut through nails on each side and remove each of the sections. Trim the excess sheeting and drywall and ensure that the lines are even down to your sub-floor.
Step 2: To accommodate your new entryway, you must frame the bottom and top of the opening. Install a 2×4 plate across your sub-floor and frame down your top header with two 2x4s. This will lower the opening to correspond with the new door dimensions.
Step 3: To bring the 2x4s flush with the remaining framing, add a plywood strip to the face of them.
Step 4: Apply silicone caulk to the face of the door opening and on the bottom plate. Have someone help you set the door into place. Check for level and plumb. If the door is not level, use shims to level it.
Step 5: Use ten-penny finish nails to secure the new door to the door frame, nailing through the molding into the house stud framework.
Step 6: Dress out the overhead area by adding a ripped 1×4 as trim for the plywood.
Step 7: If the exterior of the home is brick, finish the area around the door by setting new bricks, applying some mortar, and dressing the joints. The mortar color will look different initially but after it is fully cured, it will blend in with the existing mortar.
