So I had a new retaining wall built for the walkout from my basement, and there is a small gap (about an inch) between between the door frame and the wall. Currently it is filled with spray foam that's about 20 years old.
Quite clearly this looks crap, and is a poor choice for winter proofing. My current plan is to remove the old spray foam and replace with fresh product, then apply a veneer of mortar between the wall and doorframe. Also thinking about putting some basic white trim over the exposed section.
So my question is, if this was your house what product(s) would you use and how would you trim the door? I'm in Ontario, Canada.
