Not only were Mike and Lynn AMAZING PEOPLE, they went over and beyond the call of duty. After the first project fixing wall heater, I called them back to install my new range and install a socket for my dryer. My home was so messed up electrical wise. He repaired everything that the last person I hired messed up, went under my house, re-wired what was necessary, spent quality time on my home. Their main concern was that my house didn't catch fire, and to top that off, they're coming back next week to take care of some minor things that I did not ask them to do. Fell in love with both of them, would not and will not use anyone else EVER!

Mike went out of his way for me, though he charged a little more, but it was worth it!

Michael was really nice but more importantly his work was impeccable. Very neat and clean. The price was more than reasonable. I'm very happy with the work. Thanks for the hard work Michael.

mike and Lynn did a great job and my dog loved them! They replaced my main panel and a sub panel. Mike knows what he is doing and how to solve problems to get things to fit right. Works well with PG&E and city inspectors. Would highly recommend.

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.
