Benny was great to work with. Price was fair, they were able to schedule quickly, and overall did a great job. They cleaned up after themselves quite well. Overall pleased with the experience and looking forward to not having my HVAC suffering all day.

On 10/28/2024 E Taves had this to say:
Illinois Insulators was the first company we contacted. Benny came out to provide a quote to insulate storage space above our garage. Without a heat source in the garage, Benny said adding insulation would not help and therefore recommended we not spend the money. His honest, professional recommendation came as a pleasant surprise. His integrity is noteworthy. The next time you're looking for a reputable insulation company to work in your home or office, be sure to include Illinois Insulators on your list of contractors. Perhaps call them first! Testimonial written by E Taves on this site.

HIGHLY RECOMMEND! Overall, professional, nice easy to communicate with. Benny came out and looked over the project and sent us a quote. We had a plumbing issue and they were flexible with scheduling, coming out twice to give us time to fix the leak. After the insulator(Julian) started the job, he saw some additional needs and re-worked the material needed. We were a little confused, Benny called us, explained the changes and worked with us on the final pricing. They are great to work with!!! Appreciate you all!
