Hello,
The previous owner of my house built my 36x50 steel siding pole barn in 2004, and installed two metal-framed windows (36x48, I think). 2x4 framing was nailed between the girts inside, then 2x4s nailed on edge beside that, to frame the rough opening. The windows were nailed through the flange to the lumber. The whole shop was then wrapped in vinyl-faced fiberglass.
I don't know if the owner knew the windows were leaking but at some point he nailed Luan to the girts under the windows. I removed the Luan and the fiberglass wrap when I framed the walls so I could insulate and finish the interior.
That's when I noticed the wood was soft under the windows, and when it rained there ws water trickling down the inside of the siding.
The sill under one window was rotten, and the girt under both windows were rotting out. I cut out the rot, which didn't extend very far beyond the windows, and removed the sill as well.
The window is wrapped in dark brown metal trim on the outside, forming a gutter around the windows that also seems to act as flashing? That seems okay except there's a small gap where the corners of said metal. I think water is running down the gap between the white window and the brown trim, and dripping through that gap between the bottom and side of that metal.
The first photo is the outside of the building showing the brown trim and the white window.
The second shot shows the inside. The white window has the brown trim on the side and bottom but they don't meet in the corner. The gommed-on caulk was an "oh ****" post-leak-discovery patch since we've had quite a bit of rain this summer.
So, what's the right way to fix this? Is sealing it with silicone on the inside sufficient? Outside? Do I need to remove the window and re-do the metal (and how do I do that? I've not worked with sheet metal trim before). Something else?
All thoughts are appreciated.
