Cost: $2,250.00
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.

Review by in Lisle, IL
Cost: $2,100.00
We got a quote from Steve G. for insulating our exterior walls of our two north facing bedrooms and the garage ceiling and front overhang under those bedrooms. We always had to use portable heaters in those rooms. we had this done in Dec. 2015. Our kids came home for the holidays and we did not need the heaters. The rooms were very comfortable without them. I got the rooms ready as instructed for them to do there work. They showed up on time as quoted and covered up all items to protect from dust. They drilled the holes in the walls and ceiling (in garage and overhang), installed the blown-in insulation, plugged the holes and covered it with joint compound and they cleaned up after themselves. They were very friendly and professional. I would recommend this company for any of your insulation needs.

Review by in Brookfield, IL
We have 2 attics, an upper attic and a lower attic and the upper attic is not accessible. They insisted they could access it, and cut a hole in the closet and in the roof (without telling us). When doing the work, they told us that they could not access the upper attic. They asked if they should just spray foam into the hole in the closet. I said no because they wouldn't be able to see where they were insulating. Later, when it began to rain, my son called the company and the salesman said the leaking wasn't their fault. The salesman did then transfer my son to the owner who was rude and insulted my son. We had the roof replaced the summer before this and the roofers had taken pictures of their work and we were able to get those pictures and send them to the Better Business Bureau to show that the hole was not there in the roof. Through the Better Business Bureau, we were able to have the repairs for the hole cut in our roof repaired, and after some difficulty, the hole in the closet patched and repainted. The whole situation was a long and painful experience and I would not recommend this company to anyone.
Response by Illinois Insulators, Inc.: We never did any roof work on his house. we just insulated two of his attics. His whole issue was we had to make an access opening into the upper attic the paperwork stated we would apply one coat of compound and we did. That he would need to finish the rest of the work. We did the work for the father he understood everything the son is the one that is making the complaint. He was never part of the contract or the paperwork this is very unfair.

The crew arrived ahead of scheduled time and were very quick and thorough. They asked me to inspect the finished work and then cleaned up after themselves, inside and out. Great service provided.

Cost: $475.00
Workers were very nice and professional. Also, sales person (Gary) was nice and reliable. Job was done timely and at good quality. The only downfall was dealing with the business owner (stressfull experience).
Response by Illinois Insulators, Inc.: Was not trying to be stressful the problem was. I had 0 reception on my cell phone. when she had questions we went back and forth about 5 times with being disconnected. I already apologized for that. She had questions while the job was in progress I was dealing with projects in Coal City that had tornado damage from 2 months ago. Just an issue at Sprint And timing

Review by in Oswego, IL
They gave me a quote the same day they inspected the attic. They were on the job the next day(on time). Two workers completed the job within 2 hours. They cleaned after their work was done. They made sure I inspected their work. It was a great experience. I wish all jobs were that easy to complete.
