Review by in Rockville, MD
Their price was significantly less than two other bids. Carlos did the estimate and performed the work (service entrance cable replacement and up-to-code grounding.) He was prompt, pleasant, and efficient, explaining the whats and whys of the job, including what to expect from the city inspector and PEPCO. Sara was polite on the phone and diligent in providing all paperwork. A good experience all around.

Review by in Rockville, MD
Carlos Jimenez was extremely professional, polite, easy to communicate with, and friendly. He listened closely to what I needed to be done, provided clear input and advice on how to best accomplish the tasks, gave me the estimates I asked for, worked quickly and cleanly, and neatly completed the tasks for the day. Will request him for additional projects, however, based on reviews, it sounds like Winstar has many excellent electricians. When scheduling the appointment, the service rep was very polite and patient, and explained their procedure and pricing when I didn't understand it at first (I'm still new to home ownership).

Rich Finnerty, Sevice Expert for Winstar arrived on time, easily identifiable by his professional dress and company vehicle. He was extremely courteous, friendly and professional in his dealings with me. After a few minutes, it felt as though I had known him for years. I explained that I needed to have the electrical power to my in-ground pool light terminated, as well as, the live wire which used to supply a heater (previously removed) terminated. He thoroughly explained what needed to be done, and stated that I could watch. Rich performed the needed service in an exceptional manner, and I will recommend him to both friends and neighbors. Winstar is quite fortunate to have such an exceptional service expert as Rich out in the community representing the company. I would rate him as a definite 5 for knowledge, skill , customer service and interpersonal skills.

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.

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.
