Tom Decker of Chicago Green Insulation is the most knowledgeable professional in the spray foam industry. The spray foam they use is top notch quality. Tom and his great crew have completed several projects for us over the last couple years with outstanding results and professionalism.

These guys are great! Tom is extremely knowledgeable about the entire insulation process and materials and his guys are not only professional but care about the work they do and the cleanup.

Tom and his crew have been a great resource to help our clients. I highly recommend them.
