What I really appreciated was his follow up and his attention to detail. He was proactive, professional and he kept us informed. His customer service is outstanding as well as his professionalism. He made complete sense and communicated to me in an understandable way and his presentation was great. He made sure he called in advance on his appointments and for me everything was a pleasant experience.

Highly Recommend Zenergy for your next residential or commercial insulation project. Extremely fair bid, scheduled quickly, stayed within scope of discussed project. Well organized, discussed project during each step, Fair price for work performed. Completely winterized and sealed home to measure energy cost savings, Performed CFM Test prior to work and after to show benefits of attic, crawl space and weatherproofing our home. Do not wait hire immediately and share energy cost savings.

Review by in Wood Dale, IL
Dan did a great job showing me all of the ways my home was losing heat in the winter and then fixed the issues. Really nice guy, informative, hard working. Not only did he install lots of insulation he also sealed cracks, vented bathroom fans, sealed up an old kitchen fan, etc. He showed up as promised and completed the work in a very timely manner.

We hired Dan to insulate our attic. Dan explained all the issues we had (bathroom fans not connected to the outside, air gaps on the recessed lights, etc.). Over the course of three days Dan corrected all the issues and installed new insulation. Dan is very professional, detail oriented and a super nice guy! We would definitely recommend him to others. A+++ job! John and Kasia, Hoffman Estates, IL

Review by in Gurnee, IL
He was very responsive; seemed to have done a good job. Very nice. Not very professional though: he never discussed the kind of insulation he planned to use or provide an invoice or even a business card.

Review by in Null, IL
Dan did a great job insulating my attic. He did exactly what he said he would do, on time and at the quoted cost. He was very thorough in his work, applied foam sealant, installed baffles, installed bathroom vent access thru roof and installed blow in insulation. Nice guy as well. I'd hire him again.

Dan was very thorough in explaining the issues with our current insulation and what he could do to improve the insulation in our attic. He was able to squeeze us in a few days early and completed the work within the time frame he had proposed. He walked us through everything he did and how it would help with our concerns. He took pictures of his work to show us what he did. He was very professional, polite and timely. I would definitely recommend him to others.

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)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
