Honestly, those USB borescopes are a game changer for homeowners. I’ve used one to check a slow leak behind my washing machine—saved me a ton of hassle. They’re not perfect, but you don’t need pro-grade gear for most jobs around the house. One thing I’d push back on: don’t just rely on smell or visible dampness. Sometimes, by the time you notice either, the damage is already done. I always recommend running your hand along the baseboards and under sinks every couple months. It’s low-tech, but it catches stuff early.
I get what you’re saying about catching leaks early, but honestly, I’m a bit wary of relying just on touch or those borescopes. They’re handy, sure, but I’ve had times where a pipe looked fine and felt dry, but there was still a slow drip inside the wall—ended up with mold before I caught it. I started using a cheap moisture meter from the hardware store. It’s not fancy, but it picks up stuff my nose and hands miss. Just feels safer, especially in older homes where things can go sideways fast.
Yeah, I hear you on the moisture meters—they’re a solid backup. I’ve got one of those cheap pin-type ones too, and it’s surprising how often it catches stuff I’d never notice otherwise. I still use my borescope for tight spots, but honestly, it’s more for peace of mind than anything else. The meter’s what actually tells me if there’s a problem brewing behind the drywall.
One thing I’ve found is that in older houses, even the tiniest leak can travel way further than you’d expect. I had a spot in my basement where the meter was reading high, but the wall looked totally fine. Turned out the water was wicking along a stud from a bathroom two rooms over. Would’ve never found it by touch or sight.
I do wish the cheap meters were a bit more precise, but for the price, they’re hard to beat. Just gotta remember to check batteries every now and then... learned that the hard way when mine died mid-inspection.
That’s a good catch with the wicking—water loves to travel in ways you’d never expect, especially in those old houses where nothing’s quite square. I’m with you on the cheap meters not being super precise, but honestly, they’re usually “good enough” for tracking down the big issues. Ever tried comparing readings from your pin meter and borescope at the same spot? I’ve noticed sometimes they don’t quite agree, which makes me wonder how much hidden moisture we’re missing. Still, better than just guessing by touch or sight. And yeah, dead batteries mid-job... been there, done that.
Funny you mention the pin meter vs. borescope thing—I’ve had a couple jobs where the pin meter was screaming “wet!” and the borescope looked dry as a bone. Drives me nuts. I mostly trust the pin meter for surface stuff, but once you get into old lath and plaster, or weird layered tile jobs, all bets are off. Sometimes I feel like I’m chasing ghosts.
You’re dead right about water sneaking around in those old houses, too. I once found a leak that started on the second floor and didn’t show up until it hit the basement. The path it took made zero sense—ran along a joist, dropped down a chase, and wicked sideways for a good six feet before finally dripping out. No wonder folks get stumped by mystery moisture.
As for the cheap meters, I keep a couple in my bag just because I’m always losing or breaking the nicer ones. They’re not perfect, but they’ll at least tell you if you’re in the ballpark. I do wish they’d make one that beeps before the battery dies, though. Nothing like crawling under a house and realizing your meter’s just blinking at you.
Honestly, half the time I end up going old school—just poking around with a screwdriver and using my nose. If it smells musty, there’s probably something going on, meters or not. But yeah, I’d rather have some kind of reading than just guessing. Feels like a lot of this work is equal parts science and detective work.
Anyway, it’s good to know I’m not the only one who gets conflicting readings. Makes you appreciate when things actually line up for once.
