What should I expect to be included on the labor end of installation of a single pre-hung front entry door in stucco? i.e. My first proposal includes: "Remove existing wood door and install owner;s door into opening. Secure with tapcons into existing block opening. Add jamb extensions to door along with new casing. Putty,prep and painting of jamb and door by others. Caulk exterior jamb at new stucco surface with white urethane caulking." ALSO: The threshold on the new pre-hung door is 3/4" shorter than my current threshold; 1.5" shorter, if you include the exterior molding strip. The 3rd pic down shows a pencil mark where the new threshold would reach, if I keep the new pre-hung door flush with walls on the inside. The 1st installer says I have 2 options but either way, I will lose the exterior molding strip & not be able to replace it: 1) Keep the new pre-hung door flush with walls on the inside & fill in the gap left in the front with more stucco, which means I have to hire a stucco guy. 2) Push the new pre-hung door forward to stucco and then add strips of wood on the inside to make it flush with the walls. All helpful thoughts & opinions are greatly appreciated, Thanks!
