 Trustindex verifies that the original source of the review is Google. Bob came out to give us a quote and was incredibly knowledgeable about spray foam, taking the time to answer all of our questions. When it came time for the installation, Joe and his team arrived right on time. They were extremely polite, professional, and got straight to work masking, covering, and taping up everything to protect our home.

They worked hard for 10 hours straight and spent an hour making sure everything was thoroughly cleaned up at the end. They also performed proper adhesion and density testing on-site, providing us with a full report detailing the exact mix used and the final quantities. They did a fantastic job, and I would highly recommend them to anyone looking for a highly professional and knowledgeable crew.

 Trustindex verifies that the original source of the review is Google. Bob, Joe, and the team did a nice job adding closed cell spray foam insulation to our garage ceiling and a portion of one wall.  We were hoping to improve the comfort of the rooms above the garage with this project.  The team was committed to doing the job right and made every effort to insulate all problem areas.  Bob is honest, professional, and a great person to do business with.  He even helped make arrangements with his drywall guy, Alfonso, to replace the drywall after the foam insulation was applied.  Alfonso and team did a nice job as well.  I look forward to experiencing the full benefits of this project when the weather gets cold again.  If you are looking for somebody to help with you insulation project, I would recommend Bob and South Chicago Insulation, LLC.

 Trustindex verifies that the original source of the review is Google. 10/10 recommend if you want to work with insulators who are as honest as the day is long.  These guys went above and beyond in dealing with my village for my permit to educate them on why closed-cell foam on external walls is the only way to avoid moisture issues and get the best envelope. They hired a building scientist to educate my village officials on the numbers and research behind it. Countless hours. They did all the calls and all the work, to get code officials up to date on current best practice.  Grant it, their hope is that it will make future work in this village more seamless on the next contract, but they actually care about what they are putting in your home. They will not just put some BS combo of closed cell topped with open cell garbage just to pass an inspection by filling a wall or roof cavity.  (Which all four of my other bids proposed).  I didn’t know much about this until I met these guys. I’m so glad I did-I care about moisture issues in my house, mold and ultimately what my family is living in.  When I initially called Bob, he had to call me later that night because he was at an insulation conference.!? Who knew there were such things? They clearly care about the work they do for people and were willing to walk away from the job rather than come down in cost to do sub par work.  That speaks volumes.  I never met these guys before they bid my job and I’m not related to them. I’m a paid-in-full customer. Good people who do more than honest work who I’d recommend to anyone.

 Trustindex verifies that the original source of the review is Google. New Lenox, IL.  Had Bob and his crew come out and spray foam the exterior front wall of my home in the attic space above my front porch.   The 2 bedrooms on the second floor were colder than the rest of the upstairs and the floors were freezing cold.  The second floor joists overhang the first floor a bit and the cold air just radiated thru the joist spaces.   Once the spray foam was done the 2 bedrooms are much more comfortable.

 Trustindex verifies that the original source of the review is Google. Joe came out for an insulation estimate for a cold room in our house. As he assessed the reasons, he discovered there were “valves” in the ductwork leading to the bedroom that were partially closed. He opened them and the power of the air reaching the room instantly increased. I recommend this honest company that solved our problem for free.

 Trustindex verifies that the original source of the review is Google. Had a great experience speaking with Bob at South Chicago Insulation. Super professional, straightforward, and genuinely helpful. Took the time to answer my questions clearly and didn’t rush the conversation. If you want to work with someone who communicates well and seems to really know the insulation space, I’d recommend them.
