Where's the plaster stop?

Up close, you can see that the wood trim was installed completely wrong. The window was nailed to the sheathing, a layer of 30-lb felt was placed over the nail fin, the wood trim was not backprimed and was nailed directly over the felt. Then the stucco was brought up to the wood trim, touching it. There should be a metal stop bead between the stucco and the wood - otherwise the porous stucco just dumps moisture into the wood. Once the wood trim got wet enough (remember, it wasn't backprimed, so it soaked up the water like a sponge), it just held the water against the felt paper until it degraded the felt and rotted the OSB.

"On much older houses,the stucco always butted up to the trim.But it was always rough cedar,and it was always thought that when it was raining ,the moisture in the air would swell the cedar tight to the stucco.It may not sound like it is a good way to keep the water out,but I have patched 100's of older houses that look like new under the stucco and trim." --peewee, 10/01/05
