Very professional and reasonable pricing. My house was built in the 1950s and still had the old insulation which made the winter extremely cold and summers scorching hot, these guys were able to make all the necessary changes to make my home more energy efficient and now I can enjoy my home year round! If I decide to update the insulation in my walls too I won’t hesitate to call these guys again.
Jesse and his team were extremely professional and responsive. This team truly cares about your needs and is here to help. They took the time to meet and greet me and truly understand my insulation needs. They got in my attic in the freezing cold and game me my best option. Pricing is extremely competitive and the level of service can’t be matched. I would highly recommend this team.
Holy Moly this organization is amazing. From the initial estimate to the continuing work they are doing for me I have been nothing but impressed. They were clean, efficient and the staff was terrific.

I contacted NetZero to get a quote on updating the insulation in one part of my house. I received a detailed quote from Ryan that included my original ask, and an update to the other attic spaces in the house including air sealing that was cheaper than just the one service due to Ryan's comprehensive knowledge of the rebates offered by Xcel and the federal govt. Ryan and his team completed a full update to all my attic space insulation (knee walls, air sealing, updating to R60 insulation) for the same cost as me finishing one space DIY. His large team came in and finished the improvements in one day and cleaned up so well it was like they weren't there. One month later, my electric bill is down 29% and my gas bill 10%. Best home improvement purchase I've made to date!
We used NetZero Insulation for our previous home in Lone Tree and were incredibly impressed with the pride their team has in their work, as well as their competitive pricing. They installed insulation in my parents' home in Castle Rock, and in our new home in Castle Rock. They finished last July, our Nest noted that we used 80 hours less AC in August compared with July. Our home is SO much more comfortable, and the noise insulation has increased dramatically as well. Our family highly recommends Ryan and his team at NetZero.
NetZero air sealed my attic/garage and installed new insulation lat week. I was skeptical on how much we’d really notice, but the temperature difference of my top floor and rooms over the garage has been incredible. Ryan and team were incredibly clean, professional, and quick. They operated in unison with each of the 7 workers knowing exactly their role. Very impressive company/staff. Highly recommended!!

Excellent attic insulation removal and upgrade experience. Corrie did a thorough inspection, providing photos of all the key areas in the attic that needed to be addressed. Walked me through the various insulation options - and notably I did not feel pressured to go with the most expensive solution - she indicated for our type structure it wasn't the best path. On the day of the install, the team was on time and knew exactly how to proceed. Minimal interruptions, and again when complete, they provided many photos showing before / after. Team also performed the tests needed to qualify for the Xcel rebates and everything passed successfully. Excellent experience overall - highly recommend.
We had a great experience with Koala Insulation for our attic insulation project. Their team removed the old insulation, sealed up air gaps, and installed new insulation up to the recommended levels—including in a tight, hard-to-access attic space. From the start, they offered multiple options and quotes, were responsive to all our questions, and communicated clearly throughout. On the day of the job, they arrived on time, worked efficiently, kept everything clean, and made sure to explain every step of the process. Even the blower-door follow-up was scheduled quickly. Every person we dealt with was professional, patient, and knowledgeable. Now that summer is here, we're already noticing reduced heat in the house and enjoying the energy savings. Highly recommend Koala Insulation if you're looking for quality work and great service!
We called to get some more information and just overall help. Corrie was extremely kind, professional and quick with answers. She even did some calling around for us and helped point us in the right direction instead of us going down the rabbit hole ourselves. Amazing service thank you so much!
