DB Plumbing Doctors and Sons contacted me right away after Home Advisor's rep wasn't able to transfer my call to them. They were able to provide me with an electronic copy of an estimate based on my description of the hot water heater that needed replacing after I sent photos and were able to come out and do the replacement within a day of getting approval. They were prompt, professional and courteous.

Family owned business that you can trust and feel good about hiring. $1,000 less than the next lowest bid and $7,000.00 less than one of the mega businesses.

I had to replace my expansion tank...(It's the small blue tank that is next to the water heater)...Their price was the best compare to other....They came on time and did the job perfectly... I will use them again.

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.

DB did a great job on a complicated installation. The price was reasonable and they were dependable, professional, and knowledgeable. I have already recommended them to several other people.

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.
