 I love the phrase, so simple a trained monkey could do it. I'm Corey with Tri-County Foam Insulation. When it comes to your home and the investment you put into it, do you really want to hire a company that only does spray foam part-time? I've heard it before. You need a gun and some foam. How hard could it be? It's much harder and more involved than you think. There's definitely an education and science behind it. Our products with our installation will last for decades because our sprayers are well-trained. Not monkeys, but they do like bananas.
