Pipe Heat Cables Saved Me One Winter
Had a client last January with an old farmhouse—pipes in the crawlspace, barely any insulation, and temps dropped overnight to single digits. Even with the insulation we added, there were a couple of spots we just couldn’t get to. Ended up running heat cables along those stretches. They’re not a cure-all, but honestly, they kept things from freezing up.
I do like the low-tech stuff—insulation, regular checks, making sure everyone in the house knows where the shut-off is. But I’ve seen too many folks get caught off guard by that one cold snap. The auto shut-offs are nice, sure, but I’d say most issues I see are from people not checking their vulnerable spots or forgetting to drain outside lines.
One thing I always tell people—if you’ve got pipes running through an unheated area, don’t just rely on insulation. Insulation slows heat loss, but if it gets cold enough for long enough, it’s not going to prevent freezing on its own. That’s where those heat cables come in handy. Not fancy, just practical.
Funny thing—one year I had a customer wrap their pipes with those old-school Christmas lights (the big bulbs) as a quick fix. Not what I’d recommend, but it actually worked in a pinch. Still, heat cables are safer and designed for the job.
Bottom line: prep and vigilance matter most, but sometimes a little tech helps cover your bases. Just don’t skip the basics thinking gadgets will save you every time.
Honestly, I’ve seen folks get way too confident with just insulation too. Heat cables are a game changer for those tough spots, but yeah, nothing beats knowing where your shut-off is and checking those pipes before the cold hits. I’ve tried the Christmas light trick once—felt like I was decorating for disaster, but it did the job in a pinch. Wouldn’t make it a habit though...
Burst Pipe Panic: What Would You Do?

That made me laugh because I’ve been there, stringing up old lights on the crawlspace pipes at 2am, thinking “there’s got to be a better way.” It worked, but I kept expecting to burn the house down or at least blow a fuse. Not my proudest fix, but when you’re staring down single digits and the hardware store’s closed, you get creative.
I’m with you on not trusting insulation alone. Last winter, my neighbor swore his new foam pipe covers would handle everything. Well, we both woke up to his garage looking like a skating rink after one of the lines split. He had no clue where his shut-off was either—took us twenty minutes to find it behind a pile of old paint cans. That’s the real panic moment, water spraying everywhere and you’re digging through junk in your pajamas.
Heat cables are solid, but honestly, nothing beats knowing your layout and testing things before it gets cold. I make a habit of running through the house every fall, tracing pipes and making sure nothing’s exposed or blocked by junk. Caught one under the kitchen sink last year that was right next to an outside wall—slapped some extra insulation on and left the cabinet open during cold snaps. Simple stuff, but it saved me a headache.
I get why people want a quick fix (or something that looks good for resale), but when it comes to pipes, “out of sight, out of mind” is just asking for trouble. Sometimes you’ve got to get your hands dirty and double-check everything yourself.
Honestly, I’ve seen way too many people trust those foam covers like they’re magic shields. They help, but if you get a real cold snap, they’re just fancy pool noodles. I always tell folks—know where your shut-off is and make sure you can actually get to it. Had a customer last year who had to move a treadmill and three boxes of Christmas decorations before he could even reach his. Not fun at 3am with water everywhere. Heat tape’s good, but nothing beats just being prepared and checking things before winter hits.

That’s exactly it—access is everything. I learned the hard way during my first winter on the job. Got called out, pipes frozen, and the shut-off was behind a mountain of old paint cans. Took us longer to clear the path than to actually fix the leak. Foam covers are fine for mild nights, but if it’s dropping below 20, I’d rather double up with heat tape and check for drafts. Not worth the risk.
