Timers are a gamble, especially in those old crawlspaces where the wind just finds every crack. I’ve had pipes freeze solid in less than an hour during a cold snap, even with insulation. Sometimes I wonder if it’s worth trying to outsmart the weather or just pay the extra on the bill and sleep easier.
Foam wrap’s my go-to for spots where people mess around too. Had one tenant who thought the wool was some kind of pest nest and yanked it all off—came home to a little flood. Foam’s not perfect, but at least it doesn’t freak folks out.
Marking insulation... yeah, tape never lasts. I’ve used zip ties with tags, but honestly, your screwdriver trick is probably more reliable. Not pretty, but neither is crawling under there twice in one winter.
And vents—man, you’re right about that. One open vent can undo hours of work. I’ve started shoving old towels in them when I’m desperate. Not exactly code, but it works in a pinch...
I hear you on the foam—seems like the only thing people don’t rip off or poke at. But I still can’t shake the feeling that all this patching and improvising is just a losing battle against the cold. Ever tried those heated cables? I’m skeptical they’re worth the hassle, but some swear by them. Wonder if it’s really better than just cranking the heat and calling it a day...
Heated cables are a mixed bag, honestly. They do work if you install them right and keep an eye on 'em, but they’re not set-and-forget. I’ve seen more than a few get fried or just plain stop working after a season or two. If your pipes are in a crawlspace or somewhere really exposed, they can help, but you still need insulation—cables alone won’t cut it. Cranking the heat works for some setups but that can get expensive fast, especially if you’re trying to warm up dead space just to keep pipes safe. I usually tell folks: layer your defenses—foam first, then maybe cables if you’ve got chronic freeze spots. Otherwise, you’re just paying a lot for Band-Aids every winter.

Yeah, that’s pretty much the way I see it too. Heated cables can be helpful, but they’re not magic. I’ve seen folks rely on them and skip insulation, and it never ends well. Insulation is cheap insurance, honestly.
I’d add—if you’re going to use cables, double check the manufacturer’s install instructions. I’ve noticed a lot of failures come from stuff like overlapping cables or using the wrong extension cords. And if you’re in a spot with rodents, those things love chewing on cables for some reason... learned that the hard way.
Cranking the heat just to protect a pipe feels like overkill unless you’ve got no other choice. Layering up protection makes sense, especially if you’re in an older house where the crawlspace isn’t sealed up great.
Anyway, good advice overall. There’s no single fix that works for everyone, but combining a few strategies seems to keep things running smoother.
One thing I’d add—if you’re using heat cables, make sure you’ve got a GFCI outlet. I’ve seen too many setups where folks just plug them into whatever’s handy, and that’s asking for trouble if there’s moisture around. Also, don’t forget to check those foam sleeves every year. They get brittle or chewed up faster than you’d think, especially in crawlspaces. I’m with you on not cranking the thermostat just for pipes... feels wasteful unless it’s a real emergency. Layering insulation and cables is usually enough if you stay on top of maintenance.
