"Great job of communicating with us and letting us know what and when it was happening."

"Yesterday we had insulation and a solar fan installed in our attic and we're thrilled with the results! Brian and Jaxson were knowledgeable and friendly, explaining the benefits and addressing our questions.

We've already noticed a significant difference in our home's temperature; the insulation kept us so comfortable last night. We can't wait to see how the solar fan will improve attic airflow and reduce our energy bills. Plus, the solar fan operates on renewable energy, giving us peace of mind about contributing to a healthier environment.

I highly recommend this installation for anyone looking to enhance their home's energy efficiency. It's a worthwhile investment in comfort, savings, and sustainability. Thanks to Brian and Jaxson for a job well done!"

"Father and two young adult sons manage and operate the business, which is awesome. On my project, one son met with me in person to review the project and provide an estimate, and father and the other son completed the installation of 3" of spray foam in a large pole building. Happy with the work and happy to support this family run local business!"

"I needed to insulate my garage ceiling as I was installing a garage furnace. I called Koala Insulation and within 2 days I had someone on site giving me a free quote on the cost to complete my project. They scheduled the work to be completed in 2 weeks. I was kept informed by emails and texts as to what was going to be done and reminder notices of when they would arrive. Within 2 hours of arrival, they had completed the job. The personal service I received was excellent. I couldn't have asked for a better experience. I would recommend Koala Insulation to anyone."

"They came over to my house after I had a bad equipment rental when I tried to blow the insulation in myself. Everything they do is self contained in their trailer, so they leave no mess, and did an excellent job blowing into the correct depth. I really appreciate them saving my bacon, and at a very reasonable price. Highly, highly recommend!"

"We are absolutely thrilled with the recent installation of attic insulation and a solar attic fan by Koala Insulation! The crew was professional, efficient, and clearly explained the entire process. The solar fan is a fantastic addition, operating completely off the grid and providing excellent ventilation. We highly recommend Koala Insulation to anyone looking to improve their home's energy efficiency with quality attic insulation and a solar attic fan!"

"I recently purchased a home and the insulation in the attic was only about 3 inches thick. I shopped around to get some quotes. Koala was my first company that responded immediately and got something scheduled for an inspection. Holden came out and spent about 2 hours with me. He went through the entire project from A to Z. I was really impressed with him. I had my other companies come out but nothing compared to what Holden presented to me. They came out today to blow in the insulation. Brian who owns the company and his other son did an amazing job. It took them less than 5 hours. I love that this is a family owned business. I can’t recommend them enough."
