Update, the leak returned. We were out this weekend and it rained all day saturday into sunday and by the afternoon on Saturday, I once again noticed the slight drip, drip, drip out from under the window over the sink, down the wall onto the counter top. I just kept a rag under it until we left and when I got home, I got up on a tall bucket and looked along the top of the window, there is clearly a breach in the seal. I will be pulling the window and re-doing the seal and replacing the window this week sometime. I really hope this is the final solution. Water leaks stress me out.
I guess I could just patch that spot with some sealant, but I would rather pull the whole window and redo the entire seal and make sure it is done right.
What do you guys think:
