The electrician was well experienced and knew how the project was to be handled without any problems. Repairs to the ceiling electrical fixture is working again for lighting and fan. Arrived early and on time for the service and had a caring attitude to assist.

James Pasden is an outstanding company representative and service expert! After arriving and listening to my explanation of problems, he diagnosed it immediately, and completed the work in a timely manner. HIs illustration of the issues addressed was easy to understand, and all charges outlined up front. I would recommend this company to any who wish to be provided timely, professional, courteous service. They even offed a discount for my military service! Much appreciated!

Review by in Pasadena, MD
Greg is an electrical genius! He had to put in a new electrical panel from a 70 year old house. The wiring was dangerous from the previous owner. Greg made the house completely safe. Greg is a huge asset to Winstar and I am using Winstar next for my plumbing needs only because I was so impressed with Greg.

Great service! Ryan was great and took the time to ensure everything was in working order. After another company didn't show up for their scheduled appointment, Winstar came to the rescue and even scheduled a same day appointment. Purchased a yearly service plan. Would highly recommend!

They were on time very polite and explained what the service they performed was and gave me a copy of everything to do with the project. I will use them again when the time comes.

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.
