Illinois Insulators, Inc.

Today we had a great experience. It all started out a week ago when our estimator John came by and we explained all of our concerns.
Today they were very professional, efficient, and entertaining. They did a great job of cleaning up after themselves. Great bunch of guys — Sal the foreman, Justin, Christian, Sean, and «D».
We had blow-​in cellulose injected into 3 levels of our home in the exterior walls, and in the unfinished portion of our basement, they used batt insulation between the joists. Overall, it was a very fair price, and they delivered what they promised. I am very pleased by the service and I can already feel the difference in our home.

I was surprised at the poor quality of service these guys provided both during and after the work was completed. There were a few initial hiccups when they didn’t have a permit in my town, but they finally came and did the job. Unfortunately they ended up ripping open an 8″ hole in my roof while cutting an access hole to my upper attic, but then they then covered it up without saying anything. I found out when rainwater started pouring in through the seams of the poor patch job one evening some time later.
When I called to discuss this with the Project Manager, he and the President/​Owner refused to look at the damage and started insulting me when I pressed them. I had to open a case with Better Business Bureau for them to pay for professional repair of the roof and interior. This took months to resolve and was a royal pain.
There are lots of insulation companies out there, and I would suggest you chose another one.

Fantastic. All around. Could not have been better. Really. As good as it gets for sure.
Luke, our sales guy, popped by for a quick visit, evaluated our flat roof/​no attic situation for blow-​in cellulose, sent us a quote the same day. He knew what he was talking about, he’s clear with his terminology, I knew he wasn’t being a smarmy sales guy, there was no pressure… Bam, professional all around.
So we hired them.
And you should too. Two guys arrived spot on time, laid out a tarp up our stairs, cut a hole and got to work. In under two and a half hours they filled our vacuous insulation-​less ceiling and patched the hole back up. Patched the hole, folks. Not everyone does that.
After some minor clean up, they gave my husband the bill — exact to the penny of the quote. Amazing.
Best yet? Our upstairs is soooooo much more comfortable now.
While they are not a participating company with the utilities for rebates as those programs costs everyone more money, it’s all good as they are able to offer lower, more competitive prices.
I’m just so impressed with these guys and the way the whole process went. I’d call them back in a heartbeat.

I had foam sprayed on my rim joist, cellulose injected into my garage ceiling, and cellulose injected into some walls. Their estimate was reasonable. The estimator, Ryan, pointed out that an estimate from a competitor included spraying insulation onto the cinder blocks between my townhome and the one next door was unnecessary. They came the very next week and did the job. I took off one star because they left ugly holes that were plainly patched. They didn’t have an option to have it sanded and painted to match the rest of the wall. My utility bill this winter is lower in part to this and the attic insulation I had done by another company. My garage ceiling is under the master bedroom. The floor is no longer cold thanks to the insulation.

I’ve been needing to get my attic insulated and happened to find a Groupon for Illinois Insulators. It was the perfect opportunity so I went for it. I called them and set up a consultation; guy named Kevin came by the house and measured the coverage we’d need. He had a thermal gun (like in Holmes on Homes!) so we could actually see the cold and hot spots. He was quick, straightforward and thorough. He gave me options about where I needed more insulation like in the walls, overhang etc What was refreshing was that he wasn’t pushy about it, so that was great.
I gave the go ahead for them to do the insulation in the attic and was able to set it up to happen in the following week. The guys were very nice and covered stuff with a tarp to make sure they didn’t get dust/​dirt on it. Even then there wasn’t much if any. They were in and out in about 2 hours. Cleaned up after themselves and also showed me what the attic looked like after insulation. So it was great!
Will definitely go back to them to do the rest of the insulation in my house in the future!
