I have a walk out basement/garage. Half the house is underground and other side is not. It is brick on lower level and vinyl siding on upper part. They used extra wide starter strip on my vinyl siding and over the years and wind blowing on it it has bent the starter strip out away from the house. I am working on finishing my basement and I kept getting a cold breeze and this is where the air is from. It has pulled away from the brick probably 1/2". Any idea of what I can use to seal up this gap? The only thing I can come up with is silicone but it is too cold for that now. Any ideas?
