Review by in Vallejo, CA
My experience was great with this particular company and I would recommend it highly for anyone who has a health condition and needs to know they're living conditions to ensure peace of mind and health safety I would recommend this company and it's owner to anyone who needed a specialist in the field of mold. This company was very exceptional and showed great diligence and getting the reports back extremely fast I received the preliminary report the very next day and I'm still awaiting the sample and the final report but all in all my experience was excellent.

Quoted one price for estimate, then charged a much higher price once the initial walk thru was completed.
Response by Sherlock Homes and Mold Inspection: The client was quoted the proper price prior to the inspection. The client did not remember the price quoted at the time of the inspection. We have reached out to this client regarding his concern.

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.
