So, I've always sort of dismissed some of our energy bills, because we have an old townhome with shitty windows. We keep the thermostat low in the winter, and I even reinsulated our attic last year, but we still have drafty windows, the floor is cold by our windows, and our energy bill isn't that much improved.
I'm looking at a lot of info about DIY home sealing. I think it might be wise to caulk between the frame and panes of each window pane, as I don't see any of that going on. And I could probably improve the seal of the front door. One thing I was noticing though, is in the basement, I looked at the ceiling space by our exterior walls. There is no insulation that I could see in the ceiling at ALL, including a space that seemed to be above the foundation, that stuck out a little bit toward the exterior wall.
So, DIY'ers, where can I learn about what to insulate and what not to? My google-fu is failing me here.
