"Tyler was the first to respond to an Angi List search, came the next day, and told me that my attic insulation, while not perfect, wasn't in need of adding more. I appreciated his honesty, even at the cost of losing a contract. I recommend this company based on honesty."

"They had a great group of people to work with, The crew was there at the appointment time. Nick and his team worked together well to get the job done, including adding insulation to the attic, adding foam to all exterior walls, and insulating in the basement. This was all done in 1 day and they cleaned up after themselves. I would highly recommend them."

"Travis, Logan and Jaxon were very professional in their work and cleaned up after. Great group of men to work with and I highly recommend Koala. Also had a room fan installed. None other of the estimates I had offered a fan. Another feature Koala offered and installed was an insulated zipped hatch cover over the entrance cover into the attic to completely seal any air leakage. Highly recommend Koala"
