Tom and Chicago Green Insulation got a tough spray foam job done well. I am very satisfied.

Insulating a building today to meet or exceed the the most recent energy codes requires the knowledge of someone you might describe as a building scientist. Tom Decker, owner of Chicago Green Insulation is that guy. Pairing his knowledge with state of the art equipment and a highly skilled crew dedicated to detail he has provided our projects with an efficient and cost effective way to to improve the homes we build. Thank You Tom

As a home builder of many years, I can tell you that Not all contractors are alike. I have used Chicago Green Insulation several times, on different projects. And I can say, they did an excellent job every time. Their spray crews were dependable, and got in and got it done. Tom Decker is experienced and knowledgable in the field of building insulation, and most important, Reliable. Two thumbs up!

Tom and his crew were outstanding! My crawlspace below my kitchen was causing my kitchen to freeze in the winter and bake in the summer and Tom‘s amazing insulation solved all that. He even brought in another carpentry business that he knew of to take down a plywood ceiling outside the crawl where outside cold air was poring in. No one else would do that, and he did the job right. I will definitely use Tom and Chicago Green Insulation again and again.
