NetZero was a tiny bit more expensive but by far worth every penny. They were thorough, professional and easy to work with. The work was completed on time and we can't believe the change in the comfort of our house. They took the time to prep everything and protect our belongings. The crew was polite and friendly. We highly recommend them. read more

NetZero did a thorough job replacing our home's attic insulation. We contacted them initially to set up a quote and Sean came out to see the home. Despite not having attic access Sean properly assessed the current inadequate insulation and prescribed a reasonable plan to address the situation. Within 24 hours I received a quote where local Xcel rebates were already applied and would be handled by NetZero. Their quote was in line with other businesses but I felt assured by the thoroughness of Sean's walk-through and the details of the job we discussed. We set up the job for two weeks later. Sean arrived with his crew right on schedule in the morning. He reviewed the work with the crew and lead and reviewed everything again with me. The crew laid down floor protection and covered up furniture and equipment in the room where they were working. Throughout the day the crew lead, DJ, was communicative and friendly and everyone was working like crazy. A little after midday they had completed the work and walked me through everything they'd done in detail by showing me pictures of all the sealing, duct connecting, foam, and blow-in insulation they added. The work looked sharp and thorough. I was worried that there'd be some clean-up, especially since they were cutting two attic access points, but when they left everything looked as clean as before they arrived. Even the work on the attic access cuts was clean and looks good. Finally, immediately we've been able to tell the difference with our home holding temperatures much more steadily. We used to fall into the 50s every night and now the house holds a much higher average temperature. We can already see lower usage on our utilities online tracking and the furnace kicks on much less often. Highly recommend NetZero insulation! Thank you Sean, Ryan, DJ and team. read more

NetZero did a great job insulating and sealing our house. I'm very impressed with Doug and his crew. They arrived on time & went right to work. Finished the job in one day. The entire crew was friendly, courteous and very respectful of our property. Amazing job cleaning up when finished! I highly recommend NetZero!!! VERY PROFESSIONAL AND EASY TO DEAL WITH! read more

These guys are tops. This is my first impression as I have not used them before... but wow.. professional, clean, willing to answer additional questions above and beyond... along with doing the contracted job right! Hi praise from this side of Denver and I am sure if you use NetZero Insulation - you'll see the same. Ryan and crew are tops. No wonder they have such a high rating with Xcel Energy!! read more

From initial contact to saying goodbye to the crew after install working with NetZero was a net plus. After the Marshall Fire we needed to have our insulation removed and then replaced: Ryan, the owner, was polite and professional but more important to me is that Ryan had excellent communication and was so respectful of our family's particular mitigating circumstances. I have to give a particular shout-out to the crew who came to do the work in our large attic ... in July. They arrived early and worked quickly, cleanly, quietly. To a one they were sweet and totally respected that we have a medically fragile child and indoor-only cats. Ryan and DJ, the foreman, were also proactive in filing all the paperwork, making less work for me (which I absolutely appreciate!). Without reservation would I recommend NetZero. read more

Ryan was great to work with and answered all my questions. They were very professional and thoroughly cleaned up afterwards. They even submitted the Xcel rebate and took that off my cost upfront. When I received my Energy usage report from December 2020, I was able to compare to Nov 2017. Ryan's work was done in September of 2020 and the numbers speak for themselves. I usually would delete these reports because we always scored so poorly! read more

Literally Net-Zero! Called in office hours and got voicemail, left a message. Response? net-zero, nada, zilch, nothing. Called again a week later, same result, no answer.Left another voicemail, same deal... save your effort and find someone interested in your business. If they can't return a call you're unlikely to get anything else! read more

From my first email and phone call to my last contact I was thoroughly impressed with Ryan and his NetZero Insulation crew. I would give them bonus stars if I could. I could go on and on about Ryan's professionalism, expertise and top rate customer service as well as his crew's work ethic but more can be said by saying less. You already know the importance of insulation or you wouldn't be reading this. Our house had been poorly insulated from the day it was built and got worse over the years from people being up in our attic tramping down the original insulation, etc. The difference now in comfort is astounding. Gone is the feeling of bitter cold on bitterly cold days. The results we got ended up far better than we expected. Carpet and hand railing well protected. Clean up afterward was with HEPA filtered commercial vacuum. 100% satisfied. Highly recommended. read more

See all

I can't say enough positive things about this company; they are definitely best-in-class. Over the past 2 years we've asked them complete 3 different projects. 1) add blown-in insulation and foam seal our attic; 2) foam seal our basement; 3) add blown-in insulation for soundproofing. First, they are very competitively priced. Also, they always arrive on-time, are extremely professional, and quickly respond to my many questions. During the estimate phases, Ryan always does a great job explaining, in layman's terms, the benefits of different options. DJ, Javon, Christian, and Kike always do a great with installation, so much so that we received the highest possible rebate from Xcel Energy upon completion of the attic project (a nice surprise and unexpected because our house is 26 years old). Prior to having the attic done, our furnace or A/C would run as much as 10-12 hours a day (there were times it would literally run all day). Now that the foam sealing and blown-in insulation has been installed, the A/C only runs 4-5 hours per day (on hot 90 degree days) and the furnace only runs for 5-6 hours per day (on cold 10 degree days). We were debating between remodeling our bathroom or foam sealing and insulating. A year later we're SO glad we had NetZero make our house more energy efficient and comfortable. Our gas and electric bills usage has gone down 25-30%, and we don't have drafts like we did before. It's so nice to live in a comfortable house. As a side note, I learned at the end of the job that Ryan has an engineering degree. read more

Professional operation. Owner was onsite for most of the project. Ryan and his whole crew was hard-working and extremely respectful of us, and our home. They seem to take pride in doing quality work. Very responsive to all communication prior to the project. Highly recommend. read more

Ryan and his team are world class at what they do. And I'm not just talking about insulation and air sealing. They provide world class customer service, too. read more

I can't say enough good things about Ryan and his team. Absolute class act. I had them install a vapor barrier in my basement and add more insulation in my attic and add spray foam. It's been a few years since they installed everything and the house has been noticeably warmer in the winter and cooler in the summer. I have no doubt we're saving a lot of money on our electric bills as a result. And recently I noticed the vapor barrier was coming off the wall in an area in the basement where some other workmen had walked on it, and Ryan and his team came back and fixed it for no charge. It's hard to find people that stand behind their work like Ryan does. Definitely don't hesitate to have these guys do the work for you! Thanks again Ryan! read more

Top notch workmanship, quality, and customer service. Ryan took the time to tell me about how I could save money through rebates available. He is clearly a person if integrity. read more

Ten stars. So, so pleased. Excellent work, both thermal insulation and soundproofing. Was informed at every step of the process. Completed the job promptly and cleaned up thoroughly. Not only beat another estimate by a lot, it included more work, too. Ryan is thoroughly knowledgeable about where you're going to get the most bang for your buck and it was so great to rely on his expertise about what did and did not need to be done, including where the other quote included work that would've violated building code. If only all my contractors were this reliable. read more

Sean and Ryan, brothers, are true professionals. From start to finish. Used a thermal gun to see where leaks were and provided pictures of everything. Took their time to explain everything. Learned alot about installation. Price was as good as any other quotes. Set the standard for service. Would definitely hire again. read more

I can't speak highly enough about this company! Both Shawn and Ryan are wonderful to work with....friendly, easy going, explain everything and always ask if i have questions. One aspect of a well run company is the relationship between the employees and the boss, especially when the boss leaves and the workers stay to clean up. They had just spent several hours sucking out the old insulation and Shawn had to leave. I was worried that the workers would not clean it thourghly but i was mistaken. They did a great job! Thanks so much! read more
