See what our satisfied customers have to say about our blown in service!
They installed attic Insulation and Also a roof fan. I highly recommended to anyone needing to get theirs done. Definitely will be using again for other parts of the house as well.
I would give Koala 10 stars if I could. A great company with superb, professional technicians. They did a fantastic job on my foam insulation project (which was unique and rather custom). Cleaned up afterwards like they were never there. I HIGHLY recommend them for your insulation needs!
These guys came out and did a wonderful job and not to mention the reasonable prices. They worked effectively and efficiently to get the job done timely and professionally.
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.
Very pleased. Would recommend to anyone that needs a good company for blown in insulation. Very professional. Arrived on time. Cleaned up afterwards. Folks were courteous and answered all my questions.

Koala Insulation Exceeded our Expectations
We became acquainted with Koala Insulation through Jennifer at the 2022 St. Charles Home Show last April. From the initial attic inspection to the day of installation, Jennifer was accessible, professional and very knowledgeable, answering all our questions.
Koala installed a solar attic fan and added blown-in insulation.
Mark, Cory and his crew and Jennifer arrived on time, worked efficiently and, the work area was cleaned up at the end of the project.
With hot weather upon us this early in the year, we’re enjoying a cooler attic which will save us money on our A/C bills. And the added insulation should reduce our heating bills, too.
I would recommend Koala to anyone wanting to lower their energy consumption and their bills; they have several options available.
These Guys Rock!
These guys ROCK! Not only was the estimate for adding insulation to my 58 year old house much lower than I had anticipated, they came out when the temperature broke a record for this day in May (93 degrees) and did an amazing job! Matt paid painstaking attention to the details that were vital (covering attic fan from inside, etc), and he and Corey (sp?) were professional, despite the heat."
St Charles, MO
Professional, friendly and courteous crew did a great job installing attic insulation. The process and experience were top notch from the free estimate to work completion.
Absolutely impressed with the whole operation! From the estimate to the insulation install…all so friendly, professionalism, on time, and the insulation team did a FANTASTIC clean up job!! Highly recommend.

New Town, St Charles
2nd time using them....and once again extremely pleased of the work they performed. Wish more contractors had their competence and professionalism. Give them 5 out of 5 no problem.
Webster Groves, MO
Excellent service. Blown in insulations for two rooms. A big shout out to Jo for arranging it all so quickly, and to Josh and his mate for showing up on time, working quickly and getting the job done and the great clean up afterwards. It was not an easy job but they were pros and got it done. I have hired a lot of people to work on my homes over the years. I want people who show up when they say they will, quote me a fair price and stick with the price, do the work contracted and clean up after themselves. These folks more than checked the boxes on all accounts. I would highly recommend them
My house is newer, however had hardly any insulation in the garage. They did an awesome job from sealing where there was air leakage and canned light covers. The fiber glass blow in was quick and they cleaned up as if they were never there. I highly recommend this team and look forward to having them do my home attic very soon!
Excellent service from Koala. They were professional and made the process easy. Highly recommend this company.
They arrived and completed the job early. Very friendly and professional and cleaned up after themselves. I would recommend this company to everyone!

WOW!!! From the free quote, to install, to clean up, these guys are FANTASTIC! In a world full of horror stories on getting work done on your house, these guys are a knight in shining armor. Customer service is very responsive in text, email and phone calls to set up appts etc. We had insulation installed in our finished garage, in the ceiling (there is a bedroom above the garage). I was worried it would be a terrible mess and that it wouldn't work as well as I wanted it to, to regulate temperature. The installers left my garage cleaner than when they came and more importantly that bedroom is now staying within 1-3 degrees of the thermostat (previously a 4-8 degree difference). Highly recommend."
St Charles, MO
They were very easy to work with they did an outstanding job on my attic and garage insulation I would use them again and would absolutely recommend it
St Peters, MO
We decided last minute to remove the insulation on our renovation project. Jennifer was absolutely wonderful! She worked it out so they could do the work before we pulled down the ceilings. The crew showed up on time, were very nice, did a great job removing the insulation, and the price was honored based on a sight unseen quote. We highly recommend Koala Insulation.
We used Koala to replace old insulation in our attic recently. They did a fantastic job, were very professional, friendly and responsive. 100% satisfied and would highly recommend. They are also local and family owned, which I liked :)"
West County St Louis
Had spray foam done on my rim joists and sill plate. Service was quick and everyone involved was very polite. If I need any spray foam done on future projects, I am for sure going to call these guys.
Koala Insulation is big on customer satisfaction and customer service. They did a great job, were competitively priced, and left the job site clean. This is a great business to work with, and I highly recommend them!
Newtown St Charles, MO
Very professional and hard working. Great customer service from beginning to end. They did an excellent job installing attic insulation. Highly recommend!
Review by Orville
Project: Install or Upgrade Blown-In Insulation
Comments: It was smooth from the first contact (owners) the sales rep that gave a thorough description of material products to choose from (what was most suitable for our need and application options. We were impressed and confident enough to sign up for the job, without other quotes. A few days later, a father and son team showed up the job which was completed in about 2.5 hours, including clean up. We didn't bother with seeking other estimates and have no regrets. Orville
