Fixing wood rot on a window bumpout
I want to fix some rotting wood around a window bumpout and I'm having a hard time visualizing how this is framed.

Can I remove the rotted out bottom beam or do I need to remove the window first? Do I need to just start tearing at it or do I need to support it with some jacks and 4x4s?

...or do I just replace the exterior trim/caulk, patch the rotted hole/drywall and forget about the beam altogether...? :thumbsup:

Sorry if this is a total newbie question, I've never worked on one of these and couldn't find something similar online. Closest ones I found had brackets underneath and the roof was framed separately (not connected to the eaves like mine is) although I'm not sure that would really matter.

Thanks in advance!!

Two main reason the wood rotted is the bottom piece of trim sticks out to far so waters getting in under it, and cheap metal framed window that may form condensation on the frame.

Well yeah, the caulk is cracked and water gets in. (never mind that they caulked over rotten trim) the palm tree also hadn't been pruned in a long time and several fronds were funneling water onto the area...

So how do I fix the wood?

Looks like the PO screwed you pretty good on this attempt at DIY.Caulk would be putting a bandaid on a severed arm. That's pretty much a tearout and replace it all. It wasn't done correctly from the beginning. OSB simply isn't an exterior grade material, and it doesn't look like there's any flashing either. You need a better quality window, and the correct flashing. And a better gutter above. All of that is combining to give you what you've got, and it all needs to be fixed. It's a pretty big job for a beginner DIYer as well. This is something you might want to get a pro in there to do.

Yeah, i see what you mean about the flashing... I guess that's what turned a rotten trim issue into a structural one?

What's wrong with the quality of the window?

Can I remove the window, replace rotten wood, flash, replace window and put on the trim? Just trying to get an idea of whats involved when you say tear it out and start over. (this window was part of the original floorplan and approx 1/3 houses in the subdivision have them)
