Koala Insulation gave me a great price and great service for adding insulation to my attic. I got 4 other quotes and theirs was the best. I worked with Bob on the estimate and scheduling. He was very professional. The crew (Dylan and Woody) provided friendly and excellent service. They called before arriving, were on time and got right to work. They were done in just over an hour. Afterwards, they showed me numerous pics of my attic with the R-60 level of insulation. I am very satisfied and look forward to saving on my energy bills.
Great response and communication every step of the way from estimate to the scope of work. Even on call backs for new request items the work was completed at god speed with quality and attention to detail. I also wasn’t paid for this review like most companies do now.
Koala provided blown insulation for our entire attic and did an amazing job! They were really efficient and had the job done an hour sooner than they quoted and were extremely thorough and cleaned up everything afterwards. Great people to deal with and locally owned which is exactly what I was looking for.

Very professional, good experience from beginning to end. Had blown in attic insulation done at our home in Dandridge. Tony and Cruz did a great job. Definitely would recommend to my friends and family.
They where great to work with the did a excellent job. I had them to install spray foam insulation in my whole home along with my crawl space it was a new build . Super product, great Price and excellent service. They was in and out and ever thing was cleaned up and hauled off. The guys was very professional. Will use them again and highly recommend them.
Top notch installer! Logan was very upfront and honest in regard to some misinformation that I had received while getting bids from other installers in the area. Griffin and David thoroughly taped off the entire area and kept my Polished Concrete Floor totally clean and free from overspray. Once completed, they did an excellent job cleaning up. I will use Accucoat again and highly recommend their services.

From the start, we received great communication, well-presented explanation of project start and completion from Shaun Lovern. The Spray Foam crew were exceptionally polite and got to work right away. The crew also communicated well regarding spray foam details in our structure. The inside of the garage and shed looks really great. I would definitely use this company again. Thanks for a job well done Knoxville Accu-Coat!
I contacted Shaun to get some information and a quote for spray foam (metal building) and couldn’t be happier with the results. Everyone was very knowledgeable, professional and helpful. The installers, David and Grissom, did an awesome job from prep work to cleanup. I would do business with them again and recommend this company.
I highly recommend Accu-Coat West Jefferson for spray foam insulation as they provided a very competitive price and were willing to work with me on schedule and scope. Mike Draper and Chad Sheets were my installers and couldn't be happier with them. They started early as I was told they would and didn't waste any time prepping the site by putting up plastic sheeting while their machine is heating the components. After they were done they did a great job cleaning up taking all the plastic with them like they weren't ever there. Only evidence that they were there is a generously/evenly coated surface of spray foam. Thanks again.

Best experience ever! The technicians Carrie and Ian were both courteous and professional. Carrie communicated with me the entire installation and allowed me to periodically inspect progress. They did not rush and their work was quality start to finish. Jeff, my sales rep, was responsive and competitive. Very pleased with the results and would have them back anytime.
We did not comparison shop so I can't say how our price compared to other companies. My husband had worked with USA insulation before and wanted to use them for our insulation project We think it was worth it. We noticed differences right away. Our house was much quieter. And everyone that we worked with was great. Big shout out to work crew because they were wonderful! The project manager kept us informed every step of the way. They were respectful, efficient and cleaned up everything. They left the property looking great.
I highly recommend USA Insulation. Jeff was the best salesman! No pressure and informative. Carrie and her team did an awesome job installing our insulation in the attic. We didn't hardly know they were here. Very considerate of our home and space. Was a good experience all around.
