Windows fogged - what are my options?
I have 36yr old casement windows on my Wisconsin home. The only marking I can read is between the window pane, which says Crestpane, I think. Just about all of the windows facing the south side and west side are fogged and with what looks to be dirty calcification between the panes too. The windows are all wood, which seems to be in good condition.
I've started to do some research on windows, and I'm just not sure what my options are to fix or replace. I'd like to keep the cost down, so I'm wondering if just the double pane glass can be replaced? I'm fairly handy, so I'm also wondering if the installation is something I might be able to do on my own.
I appreciate any thoughts and advice you might have.
