All home builders will use a window manufacturer to build windows to the exact size and shape required. If you just need to replace glass in a window try Jerry's all around glass in Arlington. If you need a new window custom sized for your desired opening, you can try Nix doors and trim, or BMC design center on Camp Bowie in ft Worth. Hope this helps.
We can install windows and we can perform custom trim carpenter work around a window opening, but we do not build windows. I would suggest contacting Andersen Windows or Pella Windows to build the window you desire. Please let us know if we can send you some contacts
