There are a lot of quality window and door brands out there. Some of the most customizable and exacting windows I’ve worked with were Marvin. When it comes to custom, they can build you just about anything.
I regularly use Hurd windows and doors as well. I feel they are one of the best value windows and doors that I’ve worked with, very good quality and good price. Also, they can do quite a bit of customization if you need.
As with most products though, your satisfaction will ultimately depend in large part with the vendor you choose. In many areas, there may be more than one vendor or distributor that carries a particular brand. Make sure you find a reputable and capable vendor that you feel comfortable working with. The choices and options available with windows and doors these days are almost endless. They should be willing to spend the time with you to educate you to what those options are, their benefits or shortcomings, and how those selections will directly affect your project.
