Illinois valley insulation was exceptional! I was having many issues with heat loss and air leakage. The team from Illinois Valley Insulation came through my house with a thermal imaging camera and pin pointed every problem area and proceeded to seal those areas from leaking. Our home is now warmer and we are actually saving money every month on our heating bills. The guys were very professional and knowledgeable. You never even know they had worked in our house, they were so clean. I highly recommend to have Illinois Valley Insulation come through your house, they can definitely cut your energy costs for sure. More...

Scott is an honest business man who can be trusted to do good work at the best price.


Taking a home and making it BETTER than when we first arrived and making peoples homes more comfortable and energy efficient and safer.

( see above) Capitalism is the AMERICAN WAY! To give people what they truly need at a fair price and hear later.. "Wow we could tell the house is so much better now"! OR The problem we had is GONE NOW!

We offer a different approach. YOU WILL deal with the owner....NOT A SALESMAN. And (unless I'm not on another job).. I am present on EACH AND EVERY JOB. AND ALL MY EMPLOYEES SPEAK ENGLISH AND ARE AMERICAN CITIZENS! WE are detailed in our work down to the last bit of comfort and saving we can find. And at a better price than our competition.
