Originally I thought it was a thermocouple issue, which would have been over $200, but I was told I only had a minor issue and paid less than $100. Very honesty company.

Great quality work; done professionally and with a friendly attitude. DB listened to all our questions and suggestions when selecting the water heater and guided us to a good model. He was patient in explaining the various steps involved in the installation. It was indeed an educational experience for me and my wife, and we would definitely call David if we have any other plumbing related projects. One thing that stood out for me was their price quote, which was detailed and clear. There were no hidden costs and the total estimate was broken down into various categories such as labor, materials, permitting etc. The heater cost itself was also clearly spelt out with the model to be used. All in all, a very satisfying and pleasant experience!

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.
