RainWater intrusion around large window frame through outside stucco wall.
 

Can anyone recommend a company/person that you have had a positive repair experience within regard to rainwater leaking inside around a window frame. Looking for an expert in this area. Thanks.

I cannot recommend an expert as i usually do my own repairs, but you might check the weep holes or slots on the lower outside lip. I have seen these get clogged and then water can backup and come inside.
