Review by in Manchester, MO
Danny was amazing! He was personable and definitely knowledgeable! I felt like I went to school tonight! Not only was our door knob/lock fixed but he fully explained what needed to be done and the processes. He said he's a locksmith who can fix doors! He did that, too for us. Called this afternoon and he was at our home at 6:30 pm. Told us how WD-40 came into existence and showed us a remarkable product called Plastic Aid! THANK YOU!!

Danny Gurvis is an excellent locksmith. He went above and beyond the call of duty to help me. And I appreciate that more than he can ever know. Thank you Danny. You are great at what you do.

Review by in Ballwin, MO
Overall, we were very happy and satisfied with Danny. He fixed our problem at a reasonable rate and had the knowledge to find a really obscure part. Only wish he could have found another part the first time for another project. He also fixed something not on the list for free and we really really appreciated that. Highly recommend him for punctuality, quality and value for the money.

Danny Gurvis arrived on time and repaired my door. I was happy with his work and his pleasant demeanor. I will call him again if I have problems with other doors or locks. I would recommend him and the company to my friends.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
