H-TWO-O was great! They came out on a Sunday (in the rain) to give me a free estimate on a water main leak that was flooding my yard and my neighbors' yards. They gave me options for addressing the issue along with the pros and cons of each issue. When they came out to do the work, they were punctual and very professional. And they did a great job of cleaning up -- inside the house and outside. Thank you!

Fantastic and honest plumber that we'd happily hire again. They repaired a collapsed pipe under our basement floor and also patched the cement floor so it'd be ready for us to install new flooring. They gave us great tips on maintenance and ensured the pipe was free flowing well beyond the trouble point.

Excellent and thorough work, with explanations as to what they were doing and why. Honest, fair, and reasonable prices (at half of some bids from other companies). Personable and knowledgeable plumbers. Most trustworthy firm we have ever worked with.

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.
