There are three windows on this unit. None of them stayed open. Two glass panes had holes.
After some astronomical bids to replace these windows, I took on the challenge of repair. Most commercial window parts are not found in major big box home improvement stores. Granted, the basic parts are there for common windows. But, windows which have been around for a while….good luck with that.
My search found a few window and glass specific stores. Some will sell parts only to contractors while others turn up their noses at people who ask too many questions. But with a little persistence and gentle humor I coaxed an old timer to assist me in figuring out the parts needed. Parts in hand and two sheets of glass, this repair was not as dreaded as initially thought. Savings of over $1000! Now all three windows will stay up on their own and are leak free.
