Koala is the best. They are extremely customer focused, with clear communication, and the work they did for me was above and beyond clean and punctual. Their pricing is also very competitive. John and his team helped devise a small raised storage platform for my attic too. I recommend them without hesitation.

The Koala team did a phenomenal job insulating our crawl space. They removed the old insulation, applied the foam sealant and cleaned everything very thoroughly!
It was a pleasure to work with John, Damien and the rest of the crew!

After meeting with several insulation companies, my spouse and I selected Koala Insulation of Chicago-Western Suburbs for our sizeable job. After meeting with John Anthony, owner of this location, I was convinced that he and his team of installation pros would do a fantastic job. From contracting to scheduling, and ultimately to installation and clean-up, every detail was handled professionally, with care, and with integrity. John answered numerous planning questions in great detail and ensured his team understood the specifics of the plan. We completed air sealing (which included multiple can light fixtures) as well as blown in cellulose attic insulation and closed cell foam in a crawl space below a living space addition. John's team of Corey W, project lead; Damien, Justin, Julian, and Marco arrived on time, walked the project with me, answered any questions, and verified the project scope. Along the way, they took before, during, and after pictures to ensure we were getting the product and installation in the manner it was promised. They even provided before and after pictures of the blower door test which measures efficiency improvements and I am pleased with the 31% measured improvement following installation. Once completed, Corey called me to update me on the project status, ensured full clean-up of all spaces, and secured our home upon leaving. I fully appreciate all that they did to bring our home to R-49 and would not hesitate to use them or recommend them for a project like this in the future.

I had the pleasure of working with Koala Chicago-West starting with John A who came to assess needs & discuss the project. Attic & crawl insulation were done by Corey, Damian, Jullian and crew. They worked from 8:30-3;30, the equipment was a bit noisy but the team worked quietly & efficiently. Most impressive was how polite & kind they were. I would not hesitate to recommend them.

I was very pleased with the Koala Insulation of Chicago West team on getting my attic cleaned out and re-insulated very quickly. The Koala team impressed me with their friendly professionalism and clear communication regarding the process and timeline. I would definitely use them again if ever needed.

Corey and crew were fantastic to work with. Very respectful and knowledgeable.
John the owner came to access our Attic and what had to be done. No crazy add ons, just straight forward work. Highly recommendable.

WOW WOW WOW!!!! I've been fighting cold / hot second story rooms for years. Several HVAC visits later I finally thought insulation? Koala came in and the next week I went from about 2 inches of insulation (see before ruler photo) to a TON of insulation (see buried measure marker photo). They sealed up any air flow gaps, added insulation to attic, under the bedroom over the garage and spray foamed a closet. The changes in the house was IMMEDIATE!!! If you are thinking "Should I have my insulation checked?", don't wait call Koala! Fast, Fair, Professional and Clean! I'd do it all over again without a second thought!

Owner John came out to provide us with a quote for a smaller job in the crawl space beneath our kitchen. He was very friendly, gave us a reasonable offer, and informed us about energy rebates that would expire at the end of the year. We booked the job. The crew arrived promptly and got to work immediately. Our crawl space is not easily accessible (through an old hopper window located over the utility sink in our laundry room). They cleared out the old insulation and cleaned up years' worth of detritus. They were finished in under two hours and left everything tidy. Clear before-and-after photos were shared with us. Great work! We can't wait to reap the benefits of a well-insulated space.
