""Koala was excellent for us. Between reaching out to them, speaking to John on the phone, the in home quote and getting the work done it was complete within a week and a half. Thank you for helping us warm our home before Christmas. they left my basement so clean and finished it all in a day. When it seemed the basement required more work then anticipated, John came out to help out the guys to ensure they got it done that same day. So grateful for Koala Insulation, Thank you!"""

Sealed up Crawl Spaces with SPF
""Wow!
This company is sooo professional! Brandon & Kacy did an amazing job insulating my two large crawl spaces with spray-foam insulation! And, the attitude and professional/respectful manner was even better than the excellent quality work.
Like everybody else, I tried to find a contractor who would do the work for a cheap price. That contractor was a nightmare. Even though they did a reasonable job for my son, the other contractor ended up disappearing with my down-payment refusing to take my calls. Now I’m having to deal with the nonsense of small-claims court, etc!
Koala was so professional. Showed up day1 to quote on the job. Then they did the job the very next day! AND THEY DID IT SO WELL! My sales person John was terrific to deal with as well. He thoroughly explained all the options and helped me to get this done quickly after the other contractor !@#%& me over.
You won’t regret dealing with these people! Couldn’t be happier.""

Attic Blow In
""Casey and Brandon did a great job providing me information for the material that they was going to use in the attic and also did a great job making an area for me to store things in. Respectful and polite went above and beyond to make sure the insulation that they were going to use cover every inch and square of the attic so that the cold air can stay in the attic and not travel around the house. Awesome company to work with insulate your house or basement. Definitely check them out and don’t hesitate to give them a call. Sean and John Are great to work with. Family oriented business. I will give them a 10 star salute but google only allow me to give them 5 star""

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.""

Roof Deck Closed Cell Spray Foam/ Exterior Walls with R21K Batts
"I'm providing an update after 6 months as there was an issue with my rebate that is currently getting resolved. Not the fault of the contractor just CT being a pain in the neck. We have tenants in the house now and they say that they only have one heating unit running on a low temperature and they need to keep a window open upstairs in winter otherwise it gets too warm. So I guess Koala did a really great job with the insulation! Highly recommend them. I would like to also reiterate that their price was very fair and with my rebate the whole job only came out to around $1,200. They are affordable, do great work and their customer service is fantastic!
They did a fantastic job for a fair price. My inspection is scheduled for today but based on what I've seen it should pass with flying colors!""

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!"
