Randy & Melecio installed my attic insulation and did an amazing job! These two are the nicest, most professional, hard working guys! They really went the extra mile, placing guards on every corner wall in my house so they would not be damaged and they cleaned up so well, I can't even tell they were here. I was also a scheduling nightmare for poor Rich but he was so nice and helped me out every step of the way. Coldani Insulation is THE ABSOLUTE BEST!!!

5.0 Elizabeth E. Lodi, CA

The estimate process was easy. The crew was thorough and wasted no time. I appreciated having pictures taken of the final installation since I wasn’t too excited about the idea of climbing in the attic!

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)
