This is the full process and cost of installing injection foam insulation in existing walls of an old house that was freezing cold. We hired a professional crew to drill hundreds of holes and inject 'Amo Foam' into the hollow cavities of our exterior walls to boost our home energy efficiency. If you're considering retrofitting your home with insulation, this video breaks down the price, the technical process (foam mix, thermal camera checks), and the challenges (GFCI breakers tripping, noise).
I couldn't find a detailed consumer video on this, so I wanted to share everything from a homeowner's perspective, including the final $10,000 price tag. Watch the full video before you call a contractor!
