    Attic post-insulation

    After a bad experience with a previous insulation contractor, I found American Insulation and their great reviews, as well as recommended by some other homeowners in the area. Rick, the owner, responded quickly and gave a very fair estimate. He did a great job explaining everything that would be done, which in our case, was air sealing and insulating our attic and sunroom addition. He and his partner were the ones to actually perform the work as well, so there weren't any surprises and nothing was lost in translation. They were very professional and clean. Since we had the insulation put in, our HVAC system is running far less often than before. Would highly recommend American Insulation.

    We had hired them to come give us an estimate in March then covid happened (amongst other home disasters) this project took a back seat until August. April returned my call quickly and they were able to schedule me the following week. They came at the time I was told. I asked about 20 questions about attic insulation at the end and they answered them all. We had other estimates done and they were the most reasonable.

    I'd like to give a shout-out to April at American Insulation. Their crew installed approx 10"-12" of the blown in fiberglass insulation. They also sealed all the can lights, electrical boxes, top plates, and added the Styrofoam vent chutes to improve the circulation up in the attic. They came in with the best price and was the most prompt when I got other bids. I certainly recommend them. With natural gas prices high as they are and with a cold winter coming up, along with the tax rebates available its something I certainly recommend doing if you haven't done so already!

    They did a fantastic job with the attic insulation. It has already made a big difference keeping our house at the correct temperature.

    Randy and his team did a great job on our attic and crawl space. We had ice dams bad this winter,…read moreand my house looked worse than the neighbors'. One night the heat went out and the indoor temp dropped to 49 degrees, so that sealed the deal, we needed better insulation. They also encapsulated the crawl space with spray foam. Turns out there were mice living down there that we had no idea about. One even fell on a worker while they were pulling out the old stuff. Made sure to tell my wife who was on the fence originally about having this done. Big difference since then. No more mice sightings, heating bills are noticeably lower, and the house stays comfortable even when it's really cold outside. Solid work all around. I'd recommend them if you're dealing with the same issues.

    Nobody enjoys pouring money into the parts of their home they never see -- attics, crawl spaces,…read moreand the like. But when those areas need attention, it's essential that the work is done right and by someone you can trust. Randy and the team at Paragon Insulation & Services delivered an experience I'd recommend to anyone. My attic was poorly ventilated -- damp, musty, and overdue for attention. After deciding to bring in a professional, Randy came out to my home, thoroughly assessed the problem areas, and put together a detailed quote on the spot. The scope of work included removal of the existing insulation, air sealing around all attic entry points, sanitizing, air baffle installation, and installation of new Weather Blanket cellulose insulation. The new cellulose achieves an R-value that meets or exceeds Illinois code requirements. Paragon's pricing was competitive, though admittedly a bit higher than some of the larger corporate outfits. What made the difference was Randy's willingness to walk me through the entire plan and clearly explain what justified the investment. That transparency, combined with the comfort of working with a local, owner-operated business, made the decision easy. The crew came in and completed the job in about half a day -- fast, efficient, and clean. The entire process was documented with photos and videos, all of which were included with the final invoice. While up in the attic, they even took the time to correct some substandard work a prior contractor had left behind on my bathroom exhaust fans. I couldn't be happier with the results. I've already noticed a meaningful improvement in temperature consistency and overall comfort throughout my home. If you're looking for a trustworthy, professional insulation contractor, I wouldn't hesitate to recommend Paragon Insulation & Services.

    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.
