Basement Fiberglass with Fabric Covering
"We picked the right guys. 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. We are happy we chose Koala of Manchester for our basement ceiling insulation installation."
Stonington, CT
Mobile Home Underbelly full of Cellulose
"Very pleased with job and clean up."""
Thompson, CT
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."

Install Solar Fan, Insulation Removal, Batt Insulation Install in Basement and Cellulose in Attic
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!
