I live in Minnesota and I have experience with Hurd vinyl clad double hung windows. My windows are 10 years old and need some minor parts. Corners for the storm windows, springs and guides for the sash. My local hardware store and glass repair places were unable to locate the parts. Hurd told me to check with the suppliers listed in their web site. The suppliers told me they no longer carried the parts. Hurd keeps telling me they can't help and they ignore my emails.
