Thank you both so much for your insights and suggestions. Becky, that CSIA website is great and I have a couple of chimney folks that I will call. And I might just try to replace the cord and weights myself, being very careful to get the trim off.

Newfsmith, I have a 900 SF house, single story, with 11 windows. I also have plenty of room for storing out of season storms and screens in the basement. I think that most of the windows will be fine with some scraping and repainting. Two will need to be rebuilt, and I'll have a pro do that. I've arranged for a visit by a window person who specializes in historic windows. I think he'll be way over my budget for all of the windows, but I want to know what my options are. He might be able to do the two that need to be rebuilt.

We have several well-stocked architectural salvage places in Richmond full of windows, storm windows and screens. I've been there for other things and have perused the windows, but now that I'm in window-mode, I'll go back for a more serious look-see. Thanks for reminding me!
