"I flipped a house last year and thought sealing everything tight would solve it—nope, just made it smell like grandma's attic."
Haha, been there, done that...and still have the musty t-shirt to prove it. But honestly, I'm not totally sold on HRVs being the magic bullet either. Sure, they can help with ventilation and might trim a bit off your heating bill, but they're not exactly cheap upfront, and installation can be a headache if you're retrofitting an older home.
Personally, I've found that a balanced approach works better—seal up obvious drafts and leaks, but don't obsess over making your house airtight. A little natural airflow isn't always the enemy. I once went full-on hermetic seal mode on a flip, and ended up with condensation issues that cost me more than I saved. Lesson learned: moderation in all things, including insulation.
Yeah, totally agree about not going overboard. I've seen a few clients get carried away sealing every nook and cranny, only to end up battling mold issues later. Houses need to breathe a bit—just gotta find that sweet spot between cozy and airtight.

I get where you're coming from, but honestly, I think the whole "houses need to breathe" idea can sometimes lead folks astray. It's true you don't want your home sealed up like a submarine, but relying on natural leaks for ventilation isn't always the best way to go. I've been down this road myself, trying to balance comfort and cost without ending up with mold or drafts.
What worked for me was taking a more controlled approach rather than leaving things to chance. Instead of just letting random gaps and cracks handle airflow (which can be unpredictable and inefficient), I sealed up most of the obvious leaks around windows, doors, and outlets. Then I installed a simple mechanical ventilation system—nothing fancy or super expensive, just a basic exhaust fan in the bathroom and kitchen with timers. It made a huge difference in humidity control and air quality without breaking the bank.
Here's roughly how I tackled it step-by-step:
1. Identified major leaks using incense sticks (smoke trails show drafts clearly).
2. Sealed those leaks with weatherstripping, caulk, or foam insulation.
3. Installed affordable exhaust fans in high-moisture areas (bathroom/kitchen).
4. Set timers to run fans periodically throughout the day.
5. Monitored humidity levels with a cheap hygrometer from the hardware store.
Honestly, since doing this, my heating bills have dropped noticeably, and no mold issues so far (fingers crossed). Plus, the air inside feels fresher without that stale winter stuffiness.
So yeah, while I agree you shouldn't go crazy sealing every tiny gap obsessively, I'd argue it's better to intentionally control airflow rather than relying on accidental leaks. Just my two cents based on personal experience...
Totally agree—controlled ventilation beats random drafts any day. One thing I'd add: attic insulation. After beefing mine up, I noticed fewer temperature swings and even less condensation around windows. Small investment, big comfort boost...definitely worth considering alongside sealing leaks.
Good point about attic insulation—definitely helps smooth out those temp swings. But I'm curious, have you noticed any issues with moisture buildup in the attic itself after adding insulation? Seen a few cases where ventilation got overlooked...just something to keep an eye on.
