He heard my concerns about time and parking and sent a double crew to get everything done in one day. Crew was professional, attentive, and quick.

Recommend anyone be extra attentive to what should be masked off and closed etc, but I would use Eco Tec again and would recommend to others.

I am a general contractor with 25 years in the building trades. I contacted Tom Decker at Green…read moreChicago to discuss what I thought was going to result in a spray foam installation in one of my customers homes. Tom came highly recommended from an associate contractor who told me "he's a straight shooter and you will be impressed". So I contacted Tom and discovered this man absolutely lives up to his reputation. From the moment Tom picked up the phone I realized the guy wasn't trying to sell me anything but instead was genuinely trying to help me solve my customer's issue. In fact the issue will most likely NOT be solved by spray foam installation. In other words, he took an hour of his time on the phone with me, a total stranger, to listen, understand and analyze the problem, and then told me that what he offers is most likely not the most cost effective approach to this particular situation. He then guided me to another company he thought would be a better fit for my needs. I've been doing this a long time and it's not often you run into a guy like Tom Decker. Anybody else would have just sold me a pray foam job regardless. Not Tom Decker. What I also realized from my conversation with Tom is that he operates his company from an altruistic "big picture" perspective and he's got integrity. He could have easily sold me a spray foam job but instead chose to put my customer's best interest before his own knowing full well it would have been a sizable project. Tom also explained how his company helps the community by employing people that have had some "legal difficulties" in the past and gives them a second chance at gainful employment. This hit home with me as I am a former convict myself and is the reason I am self employed to this day. Everybody deserves a second chance. We've all made mistakes. What he's doing helps not just the guy he's giving the opportunity to, but it has positive ripple effects throughout the broader community. Very cool. My experience with Tom Decker at Chicago Green was an absolute pleasure. He could not have been more straightforward, professional, courteous, knowledgeable and an absolute class act. I am grateful to have found Tom and I look forward to dealing with him again.

We contracted with Chicago Green Insulation in October 2025 to spray closed cell foam insulation…read more(BASF HFO) in our garage and attic -- a $4,500 job. We only learned a different, unspecified product had been used because we noticed the cans on the truck didn't match BASF's packaging and asked about it directly. When asked, Tom Decker never confirmed what product was actually being installed -- only that it was "closed cell." It was the person doing the spraying who told us the product had been switched to Polycon foam. We were never notified of this substitution before or during the job. The crew also ran out of material mid-installation, left the property for over three hours, and returned after dark to finish the job. We raised concerns about the foam's appearance within days. Six months later, once we were able to fully access the space, we discovered the foam in multiple contracted areas was not closed cell at all -- rather, a thin closed cell skin covering open cell foam underneath. This was confirmed through core sampling and consultation with Polycon's technical staff. This is not a cosmetic issue: the wrong product fundamentally fails to perform as the air and moisture barrier our roof assembly requires. When we told Tom Decker what we'd found, his first response was not to address the defect -- it was to ask why we had gone up into the space at all. When pressed further, he refused to take responsibility, disputed the timeline, and pointed to boilerplate contract language rather than addressing the fact that we did not receive the product we paid for. Also of note: when we needed excess foam trimmed back, Tom quoted us $1,200 for the work -- the same subcontractor who actually performed the trimming (same person who sprayed the foam) charged us directly $650 for that exact job when we asked him separately. Tom never conducted a final walkthrough and never sent a final invoice for the remaining balance -- for six months. If he intends to point out that we were never billed in full, that's exactly the point -- there was never a formal completion of this job in the first place. Tom may claim that one of the affected areas (a gable wall) was outside the written contract. We have his own text messages confirming he offered to spray that wall and agreed to do it -- it just was never added to the paperwork. Either it was in scope and the foam there is defective, or it was out of scope and he sprayed foam on our property without authorization. Both are his responsibility. We also discovered that Chicago Green Insulation Inc. and Thomas Decker personally currently have a $45,185.17 judgment against them in Lake County (Case No. 2025AR00000938) and a soon-to-be-finalized default judgment in Cook County for $16,702.61 (Case No. 20251124549) -- both filed by their own material suppliers for nonpayment. We had planned to pursue our own legal action, but given these existing judgments it's clear we would be unlikely to ever collect a dime -- so we're posting this instead, for anyone else considering hiring this contractor. We ultimately had to pay $3,658 out of pocket -- on top of the original deposit -- to have the defective foam removed and properly reinstalled by another company. We would not recommend this contractor to anyone considering spray foam work.
