Jacob and his team were professional, helpful, understanding and all around great. Jacob asked questions to understand my whole project not just his piece of it. He noticed things that were out of his scope and helped solved problems before they happened. I look forward to working with him again!

5.0 Ruth W. Lunenburg, MA

Installation of insulation went well; EZinsul was very thorough. However, there were some clumps of insulation and a thick film of fiberglass covered everything, despite their sweeping up to â industry standardsâ . Jacob & I talked; he came back and dusted to my satisfaction. I appreciated this attention he paid to my project. I would highly recommend EZinsul. Ruth Ann White

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.
