Yesterday I started a job, and it is in a older part of town. The homeowner knows that a lot of the stuff done, was not to code, and was done wrong. There were some pretty weird things done, and frankly doing them wrong is sometimes even harder than doing them right. But he just replaced 5 windows from Pella, and they claim to be the best out there. They are the premier window supplier in the country, and this is how they left the job. 
They told him that if you wanted it more filled in we left you another tube of foam.... geee thanks. There is a half inch gap all the way around the window filled with foam that is exposed. He asked me what we could do for it, and I said "We can call Pella and tell them to get their butts out here and fix this crap. " It amazes me what people are willing to accept as finish work from people. Especially when you pay like 5 thousand for windows.
