    Had blown-in insulation and air sealing done 6 months ago and wow, what a huge difference on our energy bills! Sean, Ryan, and their crew were very professional, knowledgeable, responsive, and thorough on install day. These guys are great, don t think twice!

    Ryan and NetZero Insulation were fantastic. Ryan was always very communicative and responded to texts and emails very quickly. During the quote and installation process, Ryan and NetZero explained everything thoroughly and I trusted them to get the job done correctly. Would definitely recommend them to friends and family.

    NetZero is simply the best of the best. Very reasonably priced, informative and professional. One of the owners was here the entire time, something you do not see much anymore, just so helpful for me, ( I always ask a lot of questions). What a great team!

    I got an Xcel Home Energy Audit first, which I recommend you do. After that, I got 3 quotes and hired NetZero for several reasons: a) One of the owners showed up to give my quote; others sent employees. b) He came with a FLIR gun so he could personally evaluate my insulation situation. c) He seemed to more directly address my questions and concerns. d) They were willing to assume liability for the Xcel rebates. e) It wasn't my most important criteria, but they also had the cheapest price. On install, they showed up on-time and performed the work without incident. I had the full spectrum: attic sealing and blown-in insulation, basement sealing and rolled insulation, and spray foam in the second-story floor above the garage. When you get the Xcel rebate, Xcel calls and asks to do a follow-up inspection, which I did. They found one minor issue with the work that the told me and NetZero about. NetZero promptly followed up with me and corrected the issue. This was in the spring, so I waited until the winter to write this review. The worked-on rooms are so much more comfortable and maintain a much-more constant temperature. My energy bill has definitely dropped, but it's hard to judge exactly how much because I hadn't lived in the house a full year.

    Very professional, explained process in clear detail, addressed problem area above my expectations. Work team was great, it was obvious each person knew their role and worked quickly and diligently. Cleaned up afterwards and no mess left behind. Price was fair and very reasonable.

    Both the owners were just a pleasure to deal with. I had a smaller job but they treated my job as if it was a million dollar job. There was actually an owner that stayed here the whole time the job was being conducted. I loved that! They were all very professional with awesome personalities. The employees did an awesome job and cleaned up after they were done. I am very pleased with the whole experience and would highly recommend this business to anyone needing insulation work done.

    Seal of Approval

    What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

    1. Verify Trade License
      HomeAdvisor checks to see if the business carries the appropriate state-level license.
    2. Verify Insurance
      As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
    3. Verification of State Business Filings
      For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
    4. Criminal Records Search
      HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
    5. Sex Offender Search
      We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
    6. Bankruptcy Search
      We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
    7. Legal Search for Civil Judgments
      We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
    8. Liens Search
      We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
    9. Identity Verification (SSN)
      HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
    10. Identity Verification (Reverse Phone Lookup)
