Best caulk for interior windows?
Hello all. I live in the Washington DC area, and after this past winter's heavy snowstorms, I had water damage to the inside of my house -- a ice dam in my gutters caused water to back up and seep into the house through the frame around my replacement vinyl windows.
Everything's dry now, but the caulking around the windows is stained and cracked. Unfortunately, I don't have a good closeup picture of what I'm talking about, and my camera is broken at the moment -- but hopefully these pictures can give you an idea of the small cracks I'm referring to:
I am wondering what kind of caulk I should use to repair those cracks? Do I need to replace the old, stained caulk (and if so, how do I do that?) or can I caulk over what's already there?
Thanks so much in advance for any help you can lend!
