Is $1,090 to air sealing, rim joist spray foam, and R-60 attic insulation (without duct sealing) a fair price?
Project Details
After I removed all the old attic insulation myself (which was honestly exhausting), I was planning to do the air sealing and new insulation on my own too. But before jumping in, I decided to get a few quotes and I’m really glad I did. My Home Depot cart was already over $2,500 just for materials if I had gone the DIY route so this ended up being cheaper and professionally done. I chose the second option since duct sealing makes a big difference in air leaks and overall energy efficiency, and it’s totally worth it. I actually asked them not to blow insulation over the walkway area so I can still access it later. They air sealed underneath those boards with closed-cell spray foam, which acts as both insulation and an air barrier.
