Do not recommend. Chris was rude and could have found a better way to say he didn't want to come look at the job. Chose "I don't want to waste my time driving 3 hours to come look at the same thing again"

Blown in attic insulation replacement of old batting. After 8 months there was no improvement in heat retention of the area below the attic. In fact, the upstairs seems actually colder. Techs were courteous and respectful of home, however, I think a professional evaluation would have been wise on my part. Overall, not satisfied with results.

The Koala team and Michael were all extremely polite, knowledgeable, and transparent about each step of the project. They were easy to communicate with. The invoicing and the work were completed quickly. We had a great experience with them and would happily work with them again.

We had a great experience with Koala Insulation of North Chicagoland. They were quick to schedule an estimate, and once we approved it, they were able to complete the work promptly.
The team arrived on time, worked efficiently, and maintained a very clean job site throughout. They took the time to ask thoughtful questions to make sure they fully understood what we wanted to achieve with the project. We really appreciated how respectful and professional they were from start to finish.
Not only did they clean up after themselves, but they also cleared out a significant amount of trash that had been left in our attic by previous owners—something we hadn’t expected but were so grateful for.
We’re very happy with the results and would absolutely recommend Koala Insulation to anyone looking for a clean, efficient, and professional insulation service.

We installed dense pack cellulose insulation in the existing floor/ceiling cavity between two apartment units in order to add sound attenuation between the units. Existing drywall was kept in place - we opted to drill 2" holes in each cavity and hose in the insulation. Koala did a great job. They worked with me to problem solve issues with existing conditions in an old house. They were prompt in there execution and they communicated well throughout the process. I highly recommend Koala!
