Did you notice any issues with moisture buildup after sealing everything up tight? I've heard some mixed opinions on whether sealing all those small gaps can trap humidity and cause problems down the line. I'm planning a similar attic insulation project soon, and blown-in fiberglass is definitely on my radar due to budget constraints. Foam would be nice, but yeah...the cost is pretty steep.
Also curious—did you use any specific method or product for sealing around wiring and vents? I've seen people swear by caulk, while others prefer spray foam for those smaller gaps. Just trying to figure out the best approach before I dive in. Glad to hear your heating bills improved noticeably though; that's encouraging. Sounds like your prep work really paid off.
I sealed up my attic pretty tight last fall and haven't noticed moisture issues yet, but I did install a humidity sensor just to keep an eye on things. Curious if anyone else has tried monitoring humidity levels after sealing? Seems like cheap insurance...
I've been thinking about doing something similar, but I'm curious—have you noticed any changes in attic temperature since sealing it up? I've heard tighter sealing can sometimes trap heat, especially in summer months. Wondering if humidity sensors alone are enough or if temperature monitoring might be useful too... Has anyone else noticed temp swings after sealing their attic?
"Wondering if humidity sensors alone are enough or if temperature monitoring might be useful too..."
I'd definitely recommend temp monitoring too, especially since heat buildup can sneak up on you. After sealing mine, the attic got noticeably warmer in July. Adding a simple wireless thermometer helped me keep an eye on things.
Humidity sensors and temp monitoring are definitely useful, but honestly, I'd prioritize airflow first. Even if your attic gets warmer in summer, good ventilation usually prevents moisture buildup and mold issues better than just tracking humidity or temperature alone. Last year I redesigned a client's attic space and we found that adding a ridge vent paired with soffit vents did way more to keep things comfortable and dry than the sensors alone would have. Just something else to think about...
