Why suggest vinyl when I'm looking for wooden storms?
Vinyl doesn't have a good track record that I'm aware of and can't be repaired easily. Some of the entire windows I need to replace in the house are plastic/vinyl ones, supposed to be the best on the market at the time. They are in far worse condition than the original 118 year old windows they thought they were improving on for more than just 10 or so years.
Besides, vinyl just looks terrible on old Victorian houses. Many people have commented on how I'm so lucky to have most of the original windows in the house. When I looked at houses before buying this one, I pretty much eliminated all the houses that had newly installed (read cheap) vinyl ones. Definitely hurts the resale value big time unless the house is just being used as a rental.
The well frame pictured looks a lot worse than it is. It's the best picture I have on my computer, though. I've had some good success on cleaning up and repairing the other wells. Definitely yes on the treated lumber, though.
If you look at the picture again, you should be able to see that the entire window is above ground. The well just doesn't make sense and would look like a redneck solution to a problem that doesn't exist.
