"I spoke to three companies. Jacob at Koala gave me the most informed recommendations for keeping my house cooler. I’m already saving money!!! The installers who blew in insulation were professional, friendly, and clean. My house was left immaculate. I also installed an attic venting fan. The installation process was perfect. Again it was professional and immaculate. I highly recommend this company."

Free Estimate

"They were honest about us actually not needing insulation which was both a huge relief and confirmation that this business is reputable and actually cares about their customers. Especially as I had two other bids who came afterwards and they tried to sell us over $1000 in insulation that was not needed. If and when we do need insulation, this company has earned our respect and would absolutely earn our business."

Rob S


Denver

Blow in insulation

"I just had Koala come and spray-in insulation in an upstairs bedroom and could not be more pleased with the whole process. Everything from the quote to the actual install was communicated to me in a timely and concise manner. No hidden fees or upsells, just exactly what I asked for. On the day of the install, the two techs were extremely professional and cognizant of the fact that my wife and I were working from home. After they completed their job, they left the room just as clean as before they started. On top of all this, they beat out several other insulation installers by quite a bit. I would definitely use again and recommend Koala!"

Living Area Ceiling & Garage ceiling - Blown-In Insulation - Fiberglas

"Jacob was great to work with. He communicated well and stuck to his word throughout the entire project. He explained the process and their product. I was quoted a good price and he still made adjustments after they had completed the work due to unexpected work that did not need to get done in a specific section after all (Not their fault). He and his guys were on time the day of the job and got done on a timely manner while not rushing. Once done, they were really good about cleaning off and clearing the path to my furnace which is in the attic where the insulation took place. Any additional mess in the main living space was also cleaned up which I appreciated. I would recommend Koala if you're looking for a reliable company for a fair price."

Very thorough and professional; knowledgeable installer went out of his way to be sure I was satisfied with each phase - blown-in insulation in exterior walls which required accessing the walls from inside as we have a brick exterior, and blown in insulation in the attic. Cleaned up all the drywall dust and insulation; covered all the furniture, etc with plastic sheeting.Very pleased with the final result; house is definitely warmer without furnace running frequently."

The added insulation will help the house stay warmer in winter and cooler in summer, and it's already much quieter. We live next to a busy street, so that's very important to us."
