Bought our home last year and our bay window screens pop out every storm. Curious is I should replace the plungers on The sides and or add two more plungers?

Looking at your photos, it appears that you have an Andersen window. However your screen does not look like a genuine Andersen screen. With that being said, installing a few more pull pins like our 70-009 (or 70-008, depending on size) could help. I would just make sure the pull pins you now have are actually engaging on the sides of the window frame.
