Thanks David for coming out on a Saturday to replace a broken toilet - it was a job well done!

Locked his keys in his truck so he arrived 1 1/2 hours late. Charged $225 hour plus parts, for less than an hour of work. Was curious and worked clean. But lost first check out the truck window on the highway so we had to stop payment and write new check, minus stop payment on first check. Guess everybody could have a bad day. My hot water heater works.

My electric water heater was causing the tap water to come out scalding hot. Mr. Brown replaced the thermostats and it is much better. He is very pleasant to work with.

Dave Brown of DB Plumbing Doctors, LLC is very efficient, experienced and knowledgeable. He was always on time, very dedicated and very good in finding perfect solutions. We used him to install a gas fireplace and do plumbing work on a bathroom. We passed the inspection with flying colors and the inspector told us this was the best work he had seen in a long time..We highly recommend his work and we will also recommend him to our family and friends. We will definitely use him again in the future

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.

To find more licensing information for your state, visit our Licensing Requirements page. Note that some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
