The proposed procedure is to remove the exterior cladding of the building and do the work from the exterior of the building. An alternative approach has been proposed to do the work from the "Interior". I asked Donlaz Construction, the proposed contractor and Pella W indows, approved window manufacturer, to weigh in on this approach. In their attached letters, they have both covered this very well. I feel the bottom line is that, if work is done from interior, we can not solve all the problems with the exterior walls ofthe building. The fundamental problems with lack of drainage plain would remain. Replacing windows in existing openings would not solve window flashing problems. If stucco was cut out 8 to 12" azound windows, then windows could be flashed properly. Of course you would need to patch the stucco azound every window. ff work was done from the interior, we could repair all rotted wood members and we could also treat any mold present and after cutting out around windows we could get windows to drain properly. We could remove wet or deteriorated exterior fiberboazd sheathing between studs, but it would need to remain in front of studs. The deterioration and mold would be gone on the day work for that area is completed. But, because ofthe existing conshuction,deterioration and mold could reoccur at any time.
