I’ve actually run into this with our place—brand new build, and I just assumed everything was set up right. Turns out, the bath fan was venting right into the attic insulation, not outside. I only caught it because I noticed a musty smell after a few showers. It’s wild how quickly moisture can cause issues, even with all the latest tech. Makes me think builders sometimes focus on energy ratings but miss these basic details that end up costing us more in the long run.
- Seen this a lot, even in high-end builds.
- Always double-check vent terminations—bath fans, dryers, kitchen hoods.
- Moisture in the attic = mold, ruined insulation, and sometimes even structural rot.
- Honestly, I wish more inspectors caught this during walkthroughs, but it slips through.
- Energy ratings are great, but if the basics aren’t right, you’re just asking for headaches later.
- Quick tip: pop your attic hatch and look for ducting to daylight—if you don’t see it, something’s off.
