Two years ago I had a master suite addition put on my house, new stucco.  A final color coat was applied to the whole house, not just the addition, for a consistent look.  Unfortunately, the final color coat ended up being a disaster as I don't think the mixture was adequately stirred resulting in terribly inconsistent color.  At this point I really need to fix the problem before planting shrubs, which will make future access more difficult.

Questions:

1. Any recommendations on a good stucco person that can fix my problem?
2. Is a traditional stucco color coat the way to go, or something synthetic?
3. Are there other good options for dealing with the color problem (paint) that will last?

I'd also take a recommendation on someone to build/repair block walls.

Thanks!
