Foam sleeves are decent, but they're not always a guaranteed fix—especially if your pipes are in a tricky spot. Last winter, I had pipes running along an exterior wall in a bathroom addition. Did the foam sleeve thing, kept cabinets open, even ran a trickle of water overnight...still woke up to frozen pipes after one particularly brutal night.
Ended up pulling drywall and finding out the insulation behind the pipes was practically nonexistent (thanks, previous homeowner 🙄). Once I added proper insulation behind the pipe itself, things improved dramatically. Foam sleeves alone won't do much if the wall cavity is poorly insulated or drafty.
Bottom line:
- Foam sleeves help but aren't foolproof.
- Check what's behind your walls if freezing keeps happening.
- Sometimes you gotta bite the bullet and fix it right instead of relying on quick fixes every winter.
"Foam sleeves alone won't do much if the wall cavity is poorly insulated or drafty."
Exactly. Foam sleeves are just a band-aid if the insulation behind is garbage. Also worth checking for air leaks around outlets or fixtures—those sneaky drafts can freeze pipes faster than you'd think.

Yeah, learned that one the hard way a few winters back. Had a pipe freeze solid behind an outlet in the laundry room. Thought I was good with just foam sleeves, but turns out there was a nasty draft coming through the electrical box. Ended up having to rip out drywall and reinsulate properly. Lesson learned: foam sleeves help, but they're no substitute for sealing up those hidden drafts...
Foam sleeves definitely aren't foolproof, but honestly, tearing out drywall isn't always necessary. I've had good luck using spray foam insulation around electrical boxes—just gotta be careful not to overdo it. A thin bead around the edges usually seals things up nicely without the hassle of major repairs. Might save someone else from a weekend drywall project...

Wish I'd read this a few months ago. Last winter, I noticed some cold drafts around my kitchen sink plumbing. Being new to homeownership, I panicked a bit and assumed the worst—thought I'd have to rip out half the wall. Ended up calling my dad, who laughed and told me to calm down. He suggested spray foam insulation too, but warned me about going easy with it. Of course, I didn't listen and went a little trigger-happy with the foam can... ended up with a huge mess that took hours to clean off my cabinets and pipes.
Lesson learned: less is definitely more when it comes to spray foam. But hey, at least the drafts stopped, and I avoided tearing out drywall. Next time I'll remember your advice about keeping it thin around the edges.
