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 happy with this investment to our home!

Lisa L.

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.

Sarah J.

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!

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 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 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.

Garage Attic Insulation Add

I recently needed some insulation work done in my attic. Koala Insulation was recommended to me and the service was amazing. Bethany arrived at my house within a couple of hours of my call to do the estimate and the guys arrived a couple of days later to do the work. Fantastic service and very friendly folks. Will use them again."


Attic Top Off

I needed my loose insulation topped off in the attic of my older house (it was low and non existent in some spots!). The quote was competitive and everyone was friendly/respectful, and I didn’t feel uncomfortable letting them in my house. The work was done well, they were careful not to scratch my floors/walls and made sure I was happy with everything before I left. One of the owners also called afterwards and told me to reach out if there is anything I’m not happy with. You love to see it! Looks like great work to me, I’m sure it’ll reduce my utility bills down the road. Pretty quick service too. Bethany came out to do the quote a couple days after I called, and the crew came to do the job 4 days after I decided to go with them. I’ll definitely be using them next time I need insulation. Thanks!"


Attic Top Off

Finally, a company that showed up on time and delivered excellent service. Bethany, thank you so much for coming on a short notice to give me a give a estimate. She could have been like other companies who just rode by my house to give me an estimate or a company who never gave me a call back. I like how Bethany did not try to over sell me or made me feel like I had to make an appointment right here right now. She gave me time to think about it before making my appointment. If, I ever have a problem with my insulation Koala will be my one and only call. The crew that came today was very prompt and very professional. Thank you so much."
