A Comcast tech came to our 3-unit building, ran a new cable into the utility room, and pulled out the seal that was there before, leaving it open as we're getting cold and wet for fall.
What should I fill this gap with? Is what was there before just some generic exterior silicone caulk? I'm wary to use polyurethane foam I don't want to "glue" everything shut, and caulk can kinda be removed without much destruction. I have some window/door/siding/trim caulk, but I don't know if there's something better to fill the giant gap (or just glob it in there...)
