5.0 David Y. Islip, NY

This company was absolutely fabulous from start to finish. The communication was clear, fast and consistent and the service was impeccable. I would highly recommend them and if needed will definitely hire again.

5.0 Steve F. Huntington, NY

They installed a ev charger and were very helpful with what product to buy and where it should be installed. Cynthia was also very helpful with rebates and tax credits for the Charger. Truly one of the more professional electricians I have ever worked with.

5.0 Angelo C. Lindenhurst, NY

They are very neat and clean. My job was extra hard but they went above and beyond expectations

5.0 Nick M. Centereach, NY

5.0 Herman M. Huntington, NY

Excellent service professional and worth every dollar to hire these pros. I highly recommend them for any of your electrical needs.


Being in the Electronic industry for 37 years. I donâ t give five stars out lightening to electricians .

5.0 Neil T. Eastport, NY

Very professional company. It’s great when you deal with the owner. His staff is highly competent and was in constant communication with me so that when the electrician arrived, the job was completed quickly and cleanly. They are very experienced with the installation of Electric Vehicle home chargers. Anthony, the electrician was able to snake the wiring thru the walls so nothing was cut except for the hole for the outlet. Finally, their quote for the job was very fair and 30% below my other quote. I will certainly use them again.

5.0 Jesse M. Patchogue, NY

I had a hot tub installed by del core. I had concerns my panel wasn t strong enough to support the additional power usage I told del core electric that I had other companies estimate prior to their estimate. Sebastian gave me the honest truth. He steered me in the right direction and gave me an extremely fare price. I highly recommend his company and will definitely use them in the future.

5.0 Alonzo M. Brentwood, NY

On time, pleasant, willing to work with you on dates made sure everything was working before leaving.

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.
