Hi,
I live in a twin which is two houses, side by side. It's basicly row homes, in groups of twos. I work hard to insulate and maintain my house, but the neighbors rent and don't upkeep at all.
Our house has a finished basement and the neighbors is still a garage. The garage door is broken and lets all the cold air into their garage and is making it into our basement. If I pull off the tiles to my drop ceiling, I see the old ceiling to what was once a garage. If I poke a hole up into that ceiling, I feel tons of cold air.
How can I insulate between the houses? Anywhere in my house that is close to their open garage, I can feel the cold air coming in.
Thanks,
Al
