My point of contact made sure to check in with me throughout the process. The on site staff were knowledge and helpful.

4.0 Irene W. Gilroy, CA

The workers were prompt, polite and did a good job and the interface with the company was very smooth. It was just disappointing that the minimum job price of $800 was so high for the job that needed to be done.

5.0 Ed T. Corral De Tie, CA

Prompt, quick service, fair pricing follows through as agreed

5.0 Jim H. Soquel, CA

5.0 Alberto R. Hollister, CA

Needed to insulate my house before closing escrow, called for a quote on a Monday and they were insulating the very next day. The owner Luis Knows his stuff, very knowledgeable. Would recommend. 👍🏼👍🏼

5.0 Ruben Z. Gonzales, CA

Excellent customer service and outstanding results, they take time in explaining a project process and benefit from the various approach methods they have to offer. I highly recommend their services for both residential and industrial applications. Nor-Cal insulation takes the meaning of professional grade to a higher standard. Thank you for your expertise!

5.0 Gloria R. Hollister, CA

Very professional. Great costumer service. Great job on the install. Happy with the results. Thanks Nor-Cal

5.0 Fabian M. Livermore, CA

Luis came and estimated , gave me a date quickly and got it done. They also cleaned up very well after the job. Very important to do in my opinion.

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.
