Spotting wear and tear on used gear: my quick routine

I’ve seen some wild “fixes” over the years - one place had a garden hose clamped to a copper pipe as a “permanent” repair. Not even kidding. I get what you mean about the nose test, though. Sometimes you walk into a room and just know something’s off, even if you can’t see it yet.

For me, I always check under sinks and around toilets for any signs of old leaks - mineral stains, warped wood, or that crusty white stuff on shutoff valves. I’ve learned not to trust fresh caulk jobs either. If it looks too new, I’ll poke around for soft drywall or hidden mold. Moisture meters are handy, but I’ve found they can give false positives if you’re near metal or tile.

One trick I picked up: run your hand along the baseboards and feel for cool spots. Sometimes that’s the only clue before things get ugly. And yeah, I’ve definitely made things worse by “fixing” stuff too fast... patience is key, but it’s hard when water’s involved.

That garden hose trick cracks me up - seen it more than once, honestly. I’m always amazed what folks will call “fixed.” I’m with you on the fresh caulk, too. Sometimes it’s just hiding a bigger mess underneath. On roofs, I get the same vibe - if the patch looks too new, I start poking around for spongy decking or weird dips. Moisture meters are hit or miss for me, especially near flashing. Sometimes you just gotta trust your gut (and your nose).

That fresh caulk trick always gets a side-eye from me, too. I’ve seen sellers slap on a bead and call it “good as new,” but nine times out of ten, there’s rot or mold lurking underneath. I usually start with a gentle push around the area - if it gives, I know I’m in for a bigger job. Same goes for roof patches. A brand-new shingle in a sea of faded ones is practically an invitation to start poking around.

I hear you on moisture meters. Mine’s picked up phantom readings near flashing and chimneys more than once... sometimes the old-school sniff test tells you more than any gadget. If it smells musty, there’s trouble brewing somewhere.

You’re right to trust your gut - experience counts for a lot here. Don’t let anyone talk you out of digging deeper if something feels off. I’d rather spend an extra hour looking than get stuck with a nightmare later.

Fresh caulk is definitely one of those “if it looks too good to be true…” situations. I’ve lost count of how many times I’ve peeled back a perfect bead only to find soggy wood or, worse, carpenter ants making themselves at home. Moisture meters are handy, but yeah, they can be finicky - especially around metal. I still rely on the sniff test and a flashlight for those tight corners. Sometimes you just have to trust your instincts and not get rushed by a seller’s “quick fix.”

Fresh caulk’s like a new paint job on a 30-year-old car - sure, it looks good, but what’s really underneath? I once poked at a “perfect” seam in a bathroom and my finger went right through to mushy drywall. Now I trust my flashlight and a butter knife more than any seller’s handiwork. And yeah, the sniff test - if it smells like a swamp, it probably is. Moisture meters are great until they start beeping because of a stray nail... then it’s back to old-school detective work.
