Thanks for the tips. I’ve done a couple of them, and ought to revisit some cracks in mortar between blocks in the basement.
I oughta plastic over a bunch of my windows. All my second floor windows are old and drafty.
I wonder how the heat transfer of a cinder block wall compares to that of an insulated wood framed house. My house it entirely block construction. Great if the big bad wolf ever gives me shit, but I’m thinking not so good for heat retention.
