Hi guys i am really thinking of buying this place, it is residential zone but sort of cottage. The last owner have put insulation in the walls and roof apparently but the floor still needs insulation blow in there i guess? You can see the single electric heater. Would insulating the crawl space down there do it? I guess get propane heaters? Also see the window, is single pane, i think i would replace this with high insulation factor. Any idea of the cost for this (ontario)? I want to live there year round but don't want to freeze me tail off. Should it then be warm enough for the winters ? It is close to the lake with strong wind.
