I get the appeal of those foam gaskets—super cheap, quick to install, and they do help with drafts around outlets. But honestly, I’ve found their impact is pretty limited if the wall cavity itself isn’t insulated well. I once spent a weekend popping those into every outlet and switch, only to realize the real cold spots were coming from uninsulated rim joists and attic bypasses. If you’re tackling an old house, I’d put air sealing and proper insulation higher on the list than just relying on the little fixes. Those gaskets are more like the cherry on top, not the sundae.

That’s exactly it. I once spent hours sticking those foam jobbies everywhere, feeling like a home efficiency ninja, and then realized my attic was basically an open window. Lesson learned: get the big leaks first, or you’re just rearranging deck chairs on the Titanic.
Couldn’t agree more about prioritizing the big stuff. I got a little carried away with weatherstripping every window and door, but then found out my crawlspace vents were wide open—kind of embarrassing, honestly. It’s tempting to focus on the details because they feel manageable, but the real gains come from tackling those major gaps first. Once the attic and crawlspace were sealed up, all those little foam pieces finally started making a difference. It’s like building a puzzle—you need the border before you fill in the middle.
I hear you on the crawlspace vents—been there myself. My house is from 1912, and I swear it’s got more secret air leaks than a sieve. I spent weeks fussing over every window sash, but then realized the attic hatch was basically a wind tunnel. Once I tackled that, the drafts dropped off big time. It’s funny how the “little” stuff only works after you handle the big offenders first... kind of like trying to mop up a flood with a sponge before turning off the tap.
You nailed it with the “turn off the tap” analogy. I see people obsess over caulking every tiny crack, but if you’ve got a gaping hole in the attic or crawlspace, it’s like bailing water with a thimble. I’ve flipped a few old houses and it’s always the same—folks get hung up on window film or door sweeps, but then you pop your head into the attic and there’s daylight streaming through gaps around the hatch or chimney chase.
Honestly, I think most of the insulation guides out there make it sound way more complicated than it is. You don’t need to chase every draft until you’ve handled the big stuff—attic, crawlspace, rim joists. Once those are sealed up, all the little fixes actually start to matter. Otherwise, you’re just spinning your wheels.
Funny thing, I once spent a weekend sealing up every outlet and switch plate in a 1920s bungalow. Didn’t notice much difference until I finally insulated the attic hatch with some rigid foam and weatherstripping. After that? Whole house felt tighter overnight. Sometimes it’s just about prioritizing what’ll give you the biggest bang for your buck.
Anyway, sounds like you’re on the right track. Old houses are stubborn, but once you get those main leaks under control, everything else falls into place a lot easier. Don’t sweat chasing perfection—just focus on the heavy hitters first.
