I have two stucco houses belonging to family members in PA to remediate that are relatively newly built (6 years) but poorly detailed.
Windows were set into framing without proper flashings, drip edges, and a drainage plane, and the stucco is 5/8" and comes right to the windows without a bead (a few windows have EZ Bead, most do not).
Water is leaking into the interior in two places and the source appears to be the windows. There are also high moisture readings in other spots on all walls.
I am trying to determine if there is a proper fix short of removing all the stucco, which one stucco contractor feels is required to properly address issues.
Several other subs feel that they can cut out around windows, install flashings, beads, and caulk, and then paint with an elastomeric paint (they both seem to like Behr). The claim the paint will last many decades and stop most problems.
I do not build with stucco and am therefore eager for advice, but if I was building from scratch I would certainly install new housewrap, a drainage plane, and have a thicker wall. It appears it will cost $70k more to remove all the stucco then to try and rework it.
I'm all for the less expensive rework approach if it makes for a reliable repair, but I worry you end up with a wall detail that is not ideal. I don't have experience to decide if this is an appropriate concern and wanted to hear what any of you who might have experienced this have to say.
