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!

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.
Brentwood

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.

Amazing! - Murfreesboro

My experience with Koala was amazing from start to finish. They answered all my questions and have great communication. I received text alerts when they were in route to arrive for the quote and to start the job. Terrell and Darnell did an amazing job installing the foam insulation in my garage. They arrived on time and moved everything out of my garage before starting the work. I liked that when they left they didn’t leave a mess for me to cleanup and put everything back in my garage. They also finished the job ahead of schedule.

Terrell and Gabriel did all the work, cleaned up and made sure I was 100% satisfied. Would def use this company again.

Totally Painless Process - Glencliff

Friendly and professional, they got me a quote quickly when other places never even responded to my request and then got me on the schedule in a good amount of time. They arrived on time, insulated my whole crawlspace in about 2.5 hours and didn't leave any mess. Totally painless process.

Wonderful Experience - Bellevue

We have had such a wonderful experience with Koala. BJ and his crew did a great job with the insulation installation, then BJ went above and beyond any expectations. He returned to our house several days doing repairs, clean up, etc. Always kind and respectful, he was fastidious in every aspect of his work. When he left today we actually told him we would miss him! Two neighbors noticed and are interested in hiring Koala - good job BJ!

Great to Work With - Hendersonville

From the start, Koala Insulation of Nashville has been great to work with. Jared responded quickly to my work request, came by within two days to see what I needed done, gave me a a very competitive quote and set up an insulation install date within 10 days. They kept me informed at every step with text messages and Zach completed the work on the scheduled date. They went above and beyond what was expected, completing the job quickly and accurately. We are very pleased with Koala Insulation, highly recommend them and would use them again.

Solar Fans and Insulation - Mt. Juliet

Koala attic installed 3 solar fans, insulation and door insulation for all 3 of our attics. Jared met with us at home and explained the project in detail and gave us a very fair estimate. The day we had appointment scheduled Sean and Josh were on time, extremely kind and courteous and treated our home with respect. Both these gentlemen worked all day without a break to make sure they finished this huge project for us. Jared even came out mid way through project to touch base and make sure we were happy. It would be a huge miss for any homeowner not to use this company for your attics. I cannot say enough positive things about the company and every individual.

Get The Attic Fans - Murfreesboro

We had them install insulation in our attic. Their work solved our issue of extreme heat in our attic and upstairs rooms. We can now use the attic area to store our Christmas decorations without worrying about heat damage. And our upstairs guest bedroom now maintains a comfortable temperature for visitors.

All-around great experience. The team was polite, professional, and efficient. We have a historic home and are frequently contracting work. This was one of the smoothest running projects we've ever done. The attic is noticeable cooler, and our AC has also been running more efficiently as well. I would highly recommend their services.

Instant Temperature Difference - Green Hills - Nashville

Excellent experience from start to finish. Jared checked the attic and made recommendations for the amount of insulation we needed and suggested installing a solar vent fan. He gave us an estimated cost. No pressure which I greatly appreciated. Sean and Gary arrived on time and worked quickly. There was a small problem with the fan installation because of our flat roof but Jared came and advised them so it was done easily. They were very nice young men and cleaned up beautifully when they finished. I was very pleased with the cellulose insulation which is eco friendly and the great tax credit for the solar fan. Such a difference in the temperature in the house! Excellent company and outstanding workmanship from all. I would recommend them highly.
