Working with properties still in the works requires developing a good relationship with the owner, builder, general contractor, and other trades on-site. Our reliability and accountability really shine in this setting where a tight schedule reigns.
Residential and commercial properties already built and in-use often call for extra care and courtesy. We make sure your home or business is cleaner than we left it and treat you the way we would want to be treated.

We get there on time, every time.
No mess left behind! We clean up after ourselves.

We’ll help you choose the right insulation for your project.
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.

Basement Fiberglass with Fabric Covering

Clear communication from everyone; knew what they were doing; prompt; simultaneously friendly and professional; willing and able to negotiate details of the job; good clean-up at the end.

Dense pack in Niantic
"I had a large somewhat complex blown in cellulose wall insulation project that another contractor left unfinished. Koala was able to get me on their schedule within a couple weeks and complete the full job in 2 days. Everyone was very professional and skilled and from the moment the team showed up, everyone knew what they needed to be doing to complete the project efficiently and correctly. Blown cellulose and holes in drywall make a large mess but the Koala team went so far as to wipe down floors and horizontals with a damp rag after project completion to minimize my cleanup efforts. I received quotes from 2 other contractors in the area for the same project and Koala was the only one that was reasonably priced, the other 2 wanted to charge several thousand dollars more and couldn’t commit to the same aggressive schedule."

Highly professional, great attitude and work ethic. Really went above and beyond the call of duty. I was redoing all the insulation in my entire house when they found bats in my attic. Cool, and calm, they did the best they could and went on to another area of my home. Came back another day at no extra charge and finished the job. They also never took up my offer to buy them lunch during their work.I can't recommend enough. Great work by great guys! Thank you again!
