They analyzed the problem and discovered the abandoned outlet that was not properly wired.

Gonzaldo was the electrician. He is an expert, timely, proficient and cordial. He is proud of the work that he does and the company that he for which he works. I took several bids and Green Mechanical gave the best value. They got Permits, worked quickly and professionally. Maybe there are less expensive companies but Green Mechanical leaves you with the feeling that you received a great job for your money. I had an electrical panel upgraded-outlets installed and AC connection established.

I put a service upgrade to bid. Green Box stood out from the handful of outfits that replied. First, Tim walked me through the initial process with the utility company. Then sent Mike, an electrician to quote the work rather than a salesperson or estimator. This not only inspired confidence but also helped explain their reasonable number. They were very communicative about scheduling and coordinated their efforts with the utility company. When Mike and Nick arrived to do the work, they were efficient, neat, and dealt with some bizarre field conditions presented by our old house. I will absolutely be recommending them.

5.0 William L. Anderson Township, OR

They waited extra hours since we are late from the appointment

5.0 Margaret T. Oregon City, OR

Clear information

5.0 Jonathan R. Tualatin, OR

Great work. Very knowledgeable.

5.0 Keith R. Portland, OR

Other than some inconvenient timing issues, the EV charger install went smoothly. Bid was 1/3 the price of the highest one I received, and was reasonable for the work of installing a charger on a new 240V circuit, 1' away from an existing service panel with plenty of capacity.

Our Projects

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.
