5.0 Phalicia P. Corona, CA

Very professional. I had patio lighting installed , it looks beautiful and the job was clean and seamless. There was also an upgrade to the panel switch to make it easier to set timers and bring the overall look up to date and modern. We are very happy with the final product and plan on showing it off to family and friends.

5.0 Jose M. Upland, CA

The service was above and beyond what we expected. The creative design Mr. Kools developed and implemented literally brought our backyard to light with skylight fixtures. Highly recommend Mr. Kool for electrical work and beyond. He also installed artificial grass on our backyard walls which gave the backyard an overall elegant view.

Electrical Service by Mr. Kool was recommended to us by a neighbor who had recently utilized their services for a similar project. I contacted them, and they arrived punctually as scheduled. The technicians adhered to safety protocols by wearing masks and shoe covers. Although I offered to relax these precautions, they explained that it was part of their standard procedure. Overall, it was a pleasure working with Electrical Service by Mr Kool. They even provided a discount for senior citizens.

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.
