Southern Illinois insulation

Andrew Weaver

Very neat, professional work! I had them insulate my shop and I’m very happy with the results. I can recommend 100%. Thanks

We had A/C ducts dripping condensation getting everything wet and ruining the drop ceiling. Southern Illinois Insulation came in and sprayed closed cell foam on the ducts. They were there the day we scheduled, did a great job not getting foam on everything else and cleaned up their mess before they left.

I ultimately used another insulator but was not only impressed by Duane but educated. Even though I'm an engineer and BPI certified, Duane provided information that helped me make an informed decision. And I think it came down to pennies difference on price.

The team at Southern Il Insulation has done spray foam work at both my home and business, I highly recommend their products and services. Consistent coverage is key to a tight and well insulated building and these guys are the the best there is at doing a neat and thorough job. I have found their rates to be competitive, service timely, and estimates consistent with the invoice.
