I dunno the single pane windows on my 100 year old house also have seals around them that let water through. They really need to be fixed or replaced.
1500 is not much if you compare it with any tech device upgrade cycle.

The seal between the pane and the wood is usually glazing. If that’s failing, you need to replace it. You can buy glazing putty at a big box store, and see how to do it on YouTube. With a little practice, it’s about ten minutes/window. $15 in materials will do a dozen or so.
If it’s leaking between the wood, you need to caulk. That’s $3-$13 in materials/tools (depending on if you already have the gun) and a couple minutes labor.
You may also need some flashing over the top to direct the water away from the pane. This is slightly more complicated. Probably $30 and an hour or so.
If you don’t want to learn these skills, a handyman should be up to any of them.
Multi pane windows also need to be flashed and caulked, just like your single pane. The only piece that I mentioned that is different is the glazing. Glazing can be replaced, the interior seal on a multi-pane window cannot
... however, I do prefer the modern ones, myself. Energy loss through single-pane windows is no joke.
