6 stars across the board. Helped me immediately, looked at every option to remedy my gas hot water heater. 💯 Impressed and relieved to take a hot shower tonight. Thank you especially to Bobby and Marcus for being so kind and knowledgeable.

I called Gold Seal to fix a water leak and David K. arrived very quickly . He diagnosed the problem, fixed it and explained everything very clearly to me. David K is awesome I have used Gold Seal services several times and highly recommend them to everyone

I would not recommend Gold Seal to any one. we had sewage coming out of our floor drain in our shop bathrooms and called to have the clog/issue dealt with. The tech came out and I told them the issues we were having, then they diagnosed and said they knew exactly what it was and that they would be able to if not fix it at least make it better. they told us they had to use a piece of equipment to water jet our pipe and get it cleared. the tech never set foot into the bathroom assuring us that the water jet would solve our problem. it cost us $1500.00 and 5 days later we had the exact same problem. we are on day # 2 waiting for a tech to come and fix what was supposedly fixed when they first came out. highly not recommended to anyone.

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.
