Absolutely, that kind of savings is a game-changer. I remember when I finally sealed the drafts around my old house's doors and windows, the difference in my heating bill was startling. It took me a Saturday afternoon with some weatherstripping and caulk, but the payoff lasted all winter. There's a real satisfaction in looking at a lower utility bill knowing you directly caused it. It makes you wonder what other simple fixes we've been overlooking because they seem too technical. Now I'm tempted to check my attic this weekend, thanks for the motivation.
