Tom Decker was quickly responsive and highly professional in providing advice on an insulation problem that our Condo board is reviewing, but not proceeding with at this time. His willingness to provide technical information and guidance knowing that the job would not be let was appreciated. I would highly recommend he and his firm to all residential customers.

These guys are beyond honest, capable, and run a clean job site, and the product is top of the line. I have done 4 foam insulation projects over several remodels, 2 with Chicago Green, and I am about to do 2 more: a gut rehab of classic Chicago frame house for my mother, and our dream penthouse in Lincoln Park. You can't shoot straighter than Tom, and he gives a chance to those less fortunate to prove themselves in their work at Chicago Green. Cannot recommend higher.

Positive: Responsiveness
I am working on a small research project on energy efficiency and I had a theoretical question about spray foam. Knowing that I wasn't in immediate need of service, Tom still took the time to answer my questions. Tom is someone who seems genuinely interested in improving the energy efficiency of Chicago's buildings.

I've used Chicago Green twice. Did a great job in my crawl space. Called back a couple years later when doing a remodel. Spray foam is a great product for sealing up the house thermally. Professional crew was very experienced and did a great job.

I am a house flipper that has done more than 60 homes in the Chicago land area. Tom and his team at Chicago Green insulation have been an integral part of what we do. His and his team’s knowledge and understanding of needing to turn a profit but also understanding that the homes need to be done right has been such an asset to us. I have gone through plenty of contractors in my years, but Tom and his team just stand out as people whose honesty and professionalism are above the crowd. He doesn’t try to push products of services that we don’t need. He understands our business but also the residential
