I agree, that's why you are getting water where it shouldn't be. Bad Installation.

Remove the shutters. They don't fit the window when you do it.

That installation was never finished. There needed to be a proper curved flashing. I would replace the window. Never shutters on a bow window.

I would do a proper flat window install and all the issues will be solved and no shutters either.

All great suggestions, thank you. I inderstand about the shutters. My concern is if the brick is brighter underneath the shutters after 45 years.

I'm thinking out loud here -

A flat window won't work because the brick at the bottom follows the curve of the window.

A replacent window would still be flat on top.

I'm okay with proper curved flashing though the hubby thinks it will look stupid because we have 4 foot eaves.

Without shutters, would tge window look good without trim?

It looks like something was removed from the top of that window. Any window that projects from the exterior wall needs some sort of "roof" or flashing system to shed water away and seal it. There's nothing that i see that says the window needs to be replaced as it does that the top part needs to simply be finished. Beverely showed a nice example of what could/should be done, but there are other ways as well. It would not look "stupid" to do that, it would look normal and proper.... As far as a flat window, I was going to say the same about the curved brick at the bottom. That handcuffs you there.

HomeSealed, what are the other ways to address the top of the window?

is there a company that still makes a multi-panel blow window?

@tdemonti, it needs to be addressed with something that extends down from the brick (integrated/flashed into it) and then slopes down and directs any water over and away from the window. That example above shows metal roofing style panels, but it could be done with shingles, or a variety of materials. Sometimes material can extend vertically up to the soffit to accomplish this as well. That is actually more common that a "roof" when under an eave like this, although you seem to have a larger than normal gap from soffit to the top of that window unit-- unless the photo is deceiving. See something like this:

Obviously that is a bay with a larger projection, but something similar could be accomplished.

As far as your other question regarding "multi-panel bow windows", they certainly are made, although not quote in that same style as yours which is custom built in place as opposed to a pre-assembled unit. You can find bows from 3 to 6 panels. The closest that you would come to your exact look would be a 4 panel bow with true divided lites, I believe that Marvin makes something like that, I'm sure others do as well.

I'm going to sleep on this a few days. Thank you all so much.

@HomeSealed Exteriors, LLC I slept in it : ) and discussed with the hubby. We will likely go with refinishing the wood window and flashing above as Beverly indicates. One more question, though. Do you know if a couple of panes from the existing window be made to open?

Pretty window with good solutions proposed above. It's not made to open. If you want additional ventilation, you could install a screen door in the summer where the front door's storm door is now.
