HomeAdvisor Screened. View Details

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information or representations set forth in those profiles, as they are self-reported by the Service Professional.

Business Overview

How We Got Started

I chose to work in this industry because When I was 7 years old, my mother came into the Basement to check on me. She found me by the fuse box with the panel cover off and I was playing electrician..

We started in this industry in 1995.

We describe our business as Well established

My words of wisdom.

It takes an extra 15 minutes to do it the professional way as opposed to just getting it done!!

Ron and his helper were great. Did an excellent job on putting in new wiring for outdoor kitchen/patio and repairing some past work and making it right and up to code.

Rob and his team are great. For this particular job, he installed the fans as requested, no issues. After this job, I contacted him about some (very last minute) work I needed to get done. Rob was able to make it happen, with very short notice and he did an excellent job. Highly recommend.

They installed my ceiling fan up on my vaulted 16’ ceiling. Great all around work, reasonable price for what needed to be done. I would highly recommend for any electrical work.

Rob was professional, prompt and extremely knowledgeable. He replaced my obsolete electric panel and my family feels safer because of it. His price was more than fair.

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.
