We found a leaky pipe in our house and a big mess in the crawl space. After trying to find a plumber who wanted the job or wasn't booked for weeks I decided to start a search on HomeAdvisor. Lucky I did. Within minutes Mike from Greenbox Mechanical contacted me and we were able to arrange for a plumber to come within a couple of days to suit our schedule. This is where Justin Walters the Plumbing Genius comes into our story. Justin was on time, very professional and friendly. Within minutes he assessed the damage and located the broken drain pipe inside the wall. He fixed the pipe while being very careful to cut as little of the wall as possible (which will be easily patched up). It was a dirty job and he fixed it brilliantly. The cost for this little nightmare was also reasonable. I would never consider anyone else for any future plumbing job. I will advise anyone to call Greenbox with confidence. Call Mike Llewelyn at the Greenbox office: 503-222-0555 or e-mail:

From start to finish, they were great. Mike called me right away and got Jeff out to provide an estimate. Jeff was great, he was patient and detailed on what needed to happen without pressuring me into it one way or another. Also appreciated them getting out to fix the issue quickly once we decided on using them. I didn't feel ripped off and that's important.

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.
