My experience with Koala of NoCo was absolutely great. Very professional, kept to their schedule, and more importantly to MY schedule which was constantly, unfortunately, affecting theirs! My job was a 2600sf out-building with spray-foam walls and blow-in ceiling insulation. They did a fantastic job. Justin was super-helpful with explaining the process and went into detail when I asked questions about it. I'm an engineer and so details are my thing. He was awesome, same with the entire crew And, just for reference, right now on July 4 2025, my house has no A/C due to a failed blower motor in my HVAC system. Today, my house was 78 degrees at 2pm with outside temp being 89. In the out-building, the thermostat showed 77. So, yeah, their work is for real. I would highly recommend them for any insulation work.
Justin and his team did a great job! They gave me an estimate within minutes and had the project scheduled to be completed a few days later. Our AC still needs some work but our home is already significantly cooler! My family and I thank you for the hard work and prompt service.
Highly responsive! Responded within a day to my inquiry. Came out and made a recommendation. Estimate was reasonable. Workers came out and did the work. Fantastic results. All within about a week! Koala has set the bar for service in NoCo!
100% professional and top quality! I’m terrible with names but one of the crews name was Jason and the other was Sergio, I think. my apologies in advance for forgetting. Those guys were amazing! Super professional, answered all my questions and were incredibly respectful of our home and their impact on it. Top notch and they left everything better than how they found it. I would recommend them to anyone. Thanks guys!
We had a great experience with Justin and the Koala staff. They offered a competitive quote, communicated clearly throughout the process, showed up when they said they would, did the job effectively with friendly staff and cleaned up after themselves. What more could you want from a subcontractor? Happy to recommend.
Josh showed up on time to give me an estimate and took the time to explain to me what could be done to better insulate my home without upselling me or pressuring me into buying more than I what I felt comfortable spending. Some of our bedrooms are very cold in the winter and in the summer the house is hot and the AC runs almost all day every day. We knew that wasn’t right so decided we should have someone check our insulation. Our home was built in 2002 so codes have changed AND Colorado has gotten hotter.The actual team arrived promptly at 9am on the scheduled date and immediately got to work. They air sealed and added insulation within 3 hours in my large attic, bringing it up to code. They were professional and polite, laid down plastic and drop cloths around the attic access, and cleaned up everything and vacuumed before they left. My toddlers were very curious and the team were friendly and accommodating to them, too!I got 4 different bids for this job and I’m happy I decided on Koala. I felt the value was fair and I’m so excited to have a better insulated home for this upcoming summer!My husband and I are both Veterans so we also appreciated the veterans/military discount on the services too. I already recommended them to our neighbor with the same house build.
Working with Justin was seamless and very professional. Their scheduling system is above average and keeps you informed every step of the way. Everything is electronic and simple to sign. The crew did great work and I highly recommend them. We will be using them again in our next homes.
The crew that came worked very diligently and efficiently. Although it's hard to gauge what's going on up in the attic, from popping my head through the hole, it looks like they did everything they said they would. It was very easy to work with koala insulation, so I would recommend them.
Jasson and the team from Koala Insulation were on time, polite, professional, and courteous. Furthermore, the Koala team was very tidy and completed our insulation project quickly.
If you are looking for a knowledgeable vendor, local business owner, fair prices and quality work then Koala Insulation of Northern Colorado should be your choice. At the end of the day what I wanted was a noticeable difference to the interior comfort of the home, we made a significant investment (inspection, foam and blown-in services) and we have noticed the improvement. Your team was responsive, knowledgeable, professional and courteous.
Updating my review because I had Koala out to insulate a shed recently. They did a fantastic job with the spray foam. They left the area surprisingly clean.Before and after photos for a night a day difference! Had them blow in insulation to bring the attic from R-18ish to R-60. Can't wait to see the difference in bills! Scott and Justin were great to work with, they got me the estimate quickly and then got me scheduled within a few days. Professional, clean and on time! I'll definitely recommend Koala to anyone who needs insulation!
First off, there was absolutely no sales pressure. The installation team's punctuality and their attention to explaining both the procedure and the product was first class. Their teamwork and attention to cleanliness was very commendable. I highly highly recommend Koala. Definitely, a company of excellence and Integrity.
Great customer service they were able to get us in for a quick estimate. Josh was great, on time and explained everything so well, to our surprise we didn't even need any work done but if we ever have to we will be reaching out to Koala!
We cannot recommend this company highly enough! Justin and Scott were always exceptionally responsive, even when I texted on a weekend, not anticipating a response until the next business day. The team that came and performed the work was outstanding - professional, efficient, friendly and loved on our dogs. When Scott came to give us a quote, he had said that as soon as they left our house once the work was done (they sealed the attic, removed old insulation, filled with new insulation to code, and installed a solar fan), we'd notice a difference temperature wise. Honestly, I find it unreal, but he wasn't wrong. For example today it is 87 degrees outside, but 70 degrees in our house. We no longer need to use the AC, which is just incredible. Worth every penny - and we felt even before the work was done that the price was fair. Justin goes above and beyond, there is zero doubt about that. While we weren't able to get an XCEL rebate with this company, read the reviews for the other local companies you would receive a rebate with. Knowing this in advance, we made the decision to stick with Koala of NoCo because even without the rebate, there is no doubt in my mind we made out ahead. I would give them 20 stars if I could. If only I could say the same about the local company who installed our five indoor mini-split units prior to this attic job...
