Pipe insulation inside the walls can actually make a noticeable difference, but only if it’s done right and reaches all the vulnerable spots. I had to open up a wall during a remodel and added thick foam sleeves—haven’t had a freeze-up there since, even when it hit single digits. The drip trick is hit or miss for me too; feels wasteful, plus it doesn’t always get the coldest pipes. If you’ve got access, targeting those hidden runs with proper insulation is worth the hassle... though yeah, with old plumbing, sometimes you’re just rolling the dice.
I hear you on the insulation making a difference, but I’ve always wondered—does it actually help with noise too, or is that just wishful thinking? I swear my kitchen pipes sound like a haunted house in winter. Anyone ever notice a change after insulating, or is it just about the freeze protection?
Insulation does help with noise, but it's not a cure-all. It dampens some of the clanging and banging, especially if the pipes knock against wood or metal. If your pipes are really loud, though, it might be more about how they're secured—or not. Sometimes it's worth checking the hangers or brackets too.

That’s a good point about the brackets. I’ve seen a lot of older places where the original pipe supports have just loosened up over time, especially after a cold winter. Has anyone noticed if temperature swings make the noise worse? I always wonder if the expansion and contraction in the colder months is what starts those pipes rattling in the first place. Or maybe it’s just age catching up with the fittings...
I think you’re spot on about the expansion and contraction being a big culprit. In my old place, every winter without fail, those pipes would start banging around like they were haunted. Drove me nuts until I finally crawled under the house and realized half the brackets were just dangling there, barely holding on. Cold snaps definitely seem to make it worse—metal shrinks, wood contracts, and suddenly there’s all this movement where things used to be snug.
I’d argue it’s not just age, though. Even newer installations can get noisy if the supports weren’t installed with enough give for expansion. Some folks wrap their pipes in foam or rubber sleeves to cut down on the rattle, but honestly, if the brackets themselves are loose or missing, that’s just a band-aid. It’s worth actually checking each support point, especially in spots you don’t see every day.
One thing I’d add—don’t ignore weird noises or assume it’s “just old pipes.” Sometimes that racket is a warning sign for something more serious, like a loose joint that could eventually leak. I’ve seen people put off fixing a little noise and end up with water damage because they didn’t want to crawl into a tight spot or thought it was just seasonal settling.
If you’re not comfortable poking around or you find something that looks sketchy, it’s better to call someone in than risk a bigger mess down the line. Safety first—water damage is no joke, and neither is slipping on an icy crawlspace floor just to tighten a bracket.
