The envelope is one system. Treat it that way.

Why these go together

Water hits the wall, runs down the surface and is supposed to leave through the gutter. Paint is what stops the wall drinking any of it.

Repaint over failed stucco and you have bought two years. Do it in one scope and it lasts.

The prep nobody sees

Exterior finishes in Los Angeles fail from ultraviolet at the top of the wall and moisture at the bottom. Both are prep problems before they are paint problems, so prep is priced as part of the job.
