Trying to determine manufacturer for window warranty

Hello there!

Thanks for reaching out to us. We don't know who manufactured your window, unfortunately. If you're looking for replacement hardware, we may be able to help. We would just have to see photos of the part(s) in question to compare to our inventory. 

Oh I see. We don't sell replacement windows, sadly. I am very sorry that we aren't able to assist with determining the manufacturer; please let us know if you have any other hardware questions.
