You're spot-on about insulation being just as important as sealing. I've worked on plenty of homes from the 70s, and it's amazing how thin that attic insulation can be—sometimes barely a few inches! Beefing it up definitely helps stabilize indoor temps without making things feel stuffy. Trickle vents are great too; I've recommended them to clients who had similar issues with stale air. Every house is different, so it's all about finding what works best for your situation. Glad you found your sweet spot.
Good call mentioning trickle vents. I've seen them work wonders, but sometimes homeowners feel they're not enough during really humid months. Have you tried pairing them with exhaust fans or anything else to boost airflow? Curious if you've noticed a difference there...
Trickle vents are decent, but yeah, they don't always cut it when humidity really kicks in. I've had similar experiences—installed trickle vents when we upgraded our windows last year, and while they're great for everyday airflow, July and August still felt pretty muggy indoors. Ended up pairing them with a couple of exhaust fans (one in the bathroom, another in the kitchen). Made a noticeable difference, especially after showers or cooking. The fans help pull out that extra moisture quicker than vents alone.
Also experimented a bit with positioning a small box fan near open windows on cooler evenings. That combo seemed to keep things fresher overnight without needing AC running constantly. Not a perfect solution, mind you—still had days where nothing but cranking the AC helped—but overall, definitely worth trying if you're looking to boost airflow without breaking the bank.
I've been skeptical about trickle vents myself. We moved into our first home last spring, and the previous owners had already installed them. Initially, I thought they'd be sufficient, but during peak humidity in July, it felt like they barely made a dent. Ended up getting a hygrometer to track humidity levels—turns out they weren't dropping below 65% most days. Eventually added a dehumidifier in the basement, and that seemed to help more consistently than fans alone. Fans are decent for airflow, but sometimes you need something stronger to tackle humidity directly...
Have you checked if your basement walls are properly sealed or insulated? I had a similar issue a few years back—trickle vents alone didn't cut it for me either. Turned out moisture was seeping in through tiny cracks in the foundation. Once I patched those up and added some waterproofing paint, the humidity dropped noticeably. Dehumidifiers are great, but sometimes tackling the root cause can save you a lot of hassle down the road...

Couldn't agree more—seen this plenty of times. Had a client once who upgraded all their windows, thinking it'd fix moisture issues entirely. Helped a bit, sure, but the real win came when they sealed the foundation cracks. Glad you got to the bottom of it!

Good point, but I'd argue ventilation often gets overlooked. I've seen homes sealed up tight yet still damp inside—adding proper exhaust fans or vents can make a huge difference, sometimes more than sealing alone.

Good call on ventilation. When I first moved in, I sealed every crack I could find, thinking that'd solve the moisture issue. But nope... still had dampness until I put in a bathroom exhaust fan. Lesson learned: sealing helps, but airflow matters big-time too.
Yeah, ventilation's definitely underrated. I went through something similar—sealed everything up tight, then ended up with condensation on my new windows. Added some trickle vents later and that cleared it right up. Curious, anyone tried HRV systems for this? Worth the investment?
Ventilation's one of those sneaky things you never think about until it's too late—I learned that the hard way too. Glad the trickle vents sorted it for ya, they're like the unsung heroes of window upgrades, haha.
On the HRV front, I put one in last year. Honestly, I'm pretty happy with it. Here's my super-scientific evaluation process: First, seal everything up tight (check), second, notice condensation and panic slightly (also check), third, research endlessly online, and finally, bite the bullet and install HRV. It wasn't exactly cheap, but my indoor air quality is noticeably better now—no more dampness or condensation issues. Plus, it feels good knowing I'm not just pumping heated air straight outside anymore.
If you're planning to stick around in your place for a while, I'd say it's worth considering. But if you're moving anytime soon...maybe stick with the trusty trickle vents for now?
