See what our satisfied customers have to say about our air sealing & insulation service!

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!

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.

So pleased with the crew

The crew arrived right on time. They got right after it, waiting for the chemicals to acclimate. They covered my A/C compressor with plastic.! They worked well as a team, answering any questions I had. When they were finished they cleaned up anything that was under the addition .Both guys were very friendly and knowledgeable. I hope to have them back on my next project.

Great Job!

"?????? KUB followed up with a "good job" approval of Koala"s isolation of our attics.???????"

Knoxville

Professionalism was top notch!

From start to finish; communication was fantastic. Professionalism was top notch. They arrived when they said they would arrive. They got me the numbers when they said they'd get the numbers. They helped with filing the TVA home energy credit, along with plenty of information on how to claim as well as fill out the IRS form to get the tax credit when filing. My project ended up having a hitch as my insulation had gotten wet at some point before I moved into the house. This slowed the vacuuming a bit but they put an extra crew on it in order to still get my attic insulated in the time foot print. All so my family could get back in the house as planned. I highly recommend Koala for getting your house insulation upgraded.

Maryville

your customer service and dedication to client satisfaction impeccable

I would like to say I find your customer service and dedication to client satisfaction impeccable. You are one of a very few who actually follows up and cares about your customers. Your company should be very proud of your service and dedication.

Knoxville, TN

your thoroughness and professionalism

I wanted you to know that all of my insulation estimates were within $100 of each other but I chose you and your company because of Bob's timely response to my quote request and your thoroughness and professionalism. I'm all about value, not price. As a younger man you probably won't appreciate this as much as Bob but regardless of how much technology continues to advance, business will always be conducted by people looking each other in the eye and being able to trust each other. The other guys I spoke with weren't shady, just a little shifty. I can live with a few minutes late from them (which they were) but untucked shirts and unanswered questions just don't go over well with me so thank you again for conducting business the right way. Enjoy your time in Georgia and we'll speak again soon.
