I reasoned that I could start a discussion about spray foam solutions that would benefit many households just around here. I finally decided to upgrade the insulation in my attic and crawl space as energy prices were rising. Amazingly, I wish I had done it sooner.
Based on local contractor advice, I used closed-cell spray foam in some areas and open-cell in others; the results were instantaneous. The house seems smaller, quieter, and the heating system runs not quite as frequently. It has completely changed the game.
