replacing aluminum windows with new constr vinyl in stucco
I have bought two vinyl windows to replace the two aluminum windows in my bathroom. My house is of stucco construction, all my interior sheetrock is removed, and nominally the old and new windows are the same size.
The reason is to replace plain glass with obscured glass. The new windows are not replacement type, but are new construction.
I'm unsure how far back to remove the stucco - I would only need to remove an inch or two to remove the old window, but I'm wondering about making the new installation water tight.
Any advice on how much stucco to remove, and the best procedure for water tightness appreciated!
Oh, I'm in California so not much rain and no snow/ice if that matters.
