Reply to comment by Danitay in PSE&G gas prices wth? Any tips on reducing gas supply costs? by jdash

Just curious what the cost was to air seal the attic and your time to break even on this project? Did you do the project yourself or hire it out? Any recommendations on companies?

Total cost out of pocket hired out: $7k (we have 2 attics). We got $2k cash rebate from NJ Clean Energy Program, so $5k all in. We save about $815/year on energy costs so break even is around 6 years. They removed all the old fiberglass, vacuumed everything out and hauled away the debris. Air sealing took a full day, insulation about half a day. Two separate blower door tests (before and after) to show the 20% improved tightness data.

Thanks! Guessing mine might be a little cheaper with a single attic on 1500 sqft home. Might have to look into this myself. Getting a home energy audit soon to figure out where my biggest leaks are. $315 bill last month 😅
