Just had David and his team do blown-in in our house and the service and install was the best. They were neat clean and right away notice a huge difference in our electric bill along with overhead noise from outside from airplanes....so happy with this investment to our home!

The Koala crew did a great job. The insulation job was promptly scheduled and reasonably priced. The additional insulation should reduce my electric bill. My house needed missing insulation to be reinstalled. Jeff, and the crew were professional and super nice to deal with. Thank you so very much.

Great experience! Connor showed up on time for our consultation and he was extremely personable and real knowledgeable about all of the different insulation solutions Koala has available. I thought I would drive him crazy with all my questions, but he was patient and was able to give answers that really made sense. I decided on the spray foam, and I could not be happier with the results. I feel like I live inside a giant Yeti cooler now! I expected the foam to make a difference, but I had no idea just how effective it could be. On top of controlling the temperature, the house is a lot quieter now, which I hadn't considered when I decided to go this route. Don't hesitate to have Connor and his team out to your place. My only regret is not making this decision sooner. Thanks so much guys!

We have 3 convienant ways for you to get in touch

LEARN ABOUT air sealing!

One of the best ways to get the biggest return on your air sealing investment is to combine it with an insulation upgrade! Learn more about types of insulation that we use in our videos below!

Why air sealing is important

Insulation alone is not going to be as effective as with combining it with air sealing. To deliver the optimal improved energy efficiency, air sealing will act as a vapor barrier and stop any air from penetrating into your home.

By sealing all gaps and holes, it creates an air barrier, blocking air from passing through walls and the ceiling into the attic or outside air in filtrating into your home.

A properly sealed home will not only stop air leakage but will also keep water out, keeping your insulation in top condition. It also contributes to increased comfort, improved indoor quality, lower utility bills and controls moisture.

Koala insulation experts offer custom solutions to provide you with the right solutions for your specific needs. We offer air sealing services along with batt, spray foam and blown-in insulation products to guard against heat loss and moisture related problems.

CELLULOSE

Cellulose consists of fibers made from recycled newspaper, cardboard, or wood and is made with or without binders. Cellulose is a very common type of blown-in insulation as it is made from recycled materials and is chemically treated to resist pests, mold, and fire. Boric acid is the primary chemical used to treat Cellulose insulation and is found naturally in seawater, fruits, and plants.

FIBERGLASS

Fiberglass is made from plastic, glass, and other raw materials that are melted and spun into fibers that resemble the texture of wool. Fiberglass insulation has moisture and fire-resistant properties. Because fiberglass is made from sand and glass, it is naturally non-combustible. Fiberglass has significant recycled content with some loose-fill products containing up to 80% recycled glass.

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

Fond du Lac

Owner

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.

Menasha

Owner

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!

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.
