DEALING WITH ITCHY PINK NIGHTMARE IN MY ATTIC
I get where you’re coming from about the moisture concerns. I’ve actually used caulk under tape on a few jobs, mostly when I’m dealing with older homes where the seams are a little rough or the vapor barrier’s questionable. In my experience, if you’re using a high-quality acrylic latex caulk and you let it cure properly before taping, you’re not really trapping moisture—you’re sealing out air leaks that would otherwise let humid air in. The real issue is when folks skip proper ventilation in the attic or above bathrooms. That’s when condensation becomes a nightmare, no matter what you do at the seams.
Honestly, I’d be more worried about poorly installed bath fans or blocked soffit vents than caulk under tape. If your attic’s breathing right and you’ve got a continuous vapor barrier, that seam detail just adds insurance. But yeah, if there’s any doubt about airflow up there, I’d fix that first before worrying about seam treatments. Seen too many moldy attics from bad venting... not fun to remediate.

- Totally agree on venting being the bigger headache. I’ve seen “sealed” attics with perfect vapor barriers still get damp if the airflow’s messed up.
- Curious—anyone ever try those smart vent fans that kick on with humidity? Wondering if they’re worth the hype or just another gadget.
- I’m always a bit skeptical about caulk under tape, though. If the caulk shrinks or cracks over time, does it really help long-term? Maybe I’m overthinking it, but I’ve seen some seams open up after a few seasons.
- At the end of the day, I’d rather spend money on better venting than fancy seam treatments. Mold cleanup is brutal... learned that the hard way in a flip last year.

Couldn’t agree more—venting issues have cost me more headaches (and cash) than anything else. Had a place a few years back where we did everything “by the book” with vapor barriers, but missed a couple soffit vents. Ended up with condensation and a patch of mold right above the master bedroom. Never again. As for those smart vent fans, I’ve tried one in a rental—seemed to help, but honestly, nothing beats just making sure you’ve got solid passive airflow to start with. The gadgets are nice, but they’re not magic.
You nailed it—venting is one of those things that’s easy to overlook until you’re knee-deep in insulation and wondering why everything feels damp. I’ve seen folks spend a fortune on high-end insulation, but if the airflow isn’t right, it’s just asking for trouble. Sometimes the simplest fixes—like clearing blocked soffits or adding a ridge vent—make the biggest difference. Don’t beat yourself up over past mistakes; every project teaches you something new.

Man, I totally get the frustration. I once worked on a reno where the homeowners had gone all-in on fancy insulation, but skipped checking the vents. The place felt like a sauna in summer and a freezer in winter—plus, that musty smell just wouldn’t quit. We ended up pulling back some of the insulation to clear out the soffits, and it made a world of difference. It’s wild how something as simple as airflow can make or break a space. And yeah, I’ve definitely learned the hard way that “out of sight, out of mind” doesn’t really apply to attics...
