    1.0 Jerome B. Mill Valley, CA

    I hired them to repair a toilet. I was told about the **travel charge** before they arrived. When he arrived, it was very clear that all he wanted to do was sell me a new toilet. When I did not accept his offer, he gave me an invoice for the travel charge, collected the check, and left. It was obvious that he never intended to even look at the toilet repair. I had to call another plumber who came out and repaired the toilet.

    4.5 Cindy L. Guerneville, CA

    From their sales rep to their installers and inspectors, all were very nice to work with and responded quickly to my request and did a wonderful job.

    5.0 Bob R. Novato, CA

    Great job on time!

    5.0 Laura P. Rohnert Park, CA

    Excellent professional, thorough. Only reservation: Final cost was much higher than estimate. Much up-selling including paying in advance for return visit next year. Sold as a membership.

    5.0 Dave G. Corte Madera, CA

    Christian did a great job. It proved to be a little more difficult than anticipated, but Christian was patient and diligent, and got the job done right. We're thankful for his hard work and would definitely use Ongaro & Sons again.

    5.0 Richard W. Petaluma, CA

    I'm very glad to have their work. I will call them again if the need ever arises.

    5.0 Paula C. Larkspur, CA

    Very pleasant and knowledgeable. Cleaned up after himself and left nothing undone. Very satisfied.

    4.0 Mary T. San Rafael, CA

    Very friendly staff to work with and willing to give information

    5.0 Debbie F. Sonoma, CA

    Our furnace is 30 years old and occasionally didn't "fire up" right away. Nick did a diagnostic check up and recommended a circuit board replacement.

    HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

    HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.
    To find more licensing information for your state, visit our Licensing Requirements page.

    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.
