5.0 Charles V. Port Jefferson, NY

DZ gave me a date for the work and showed up on-time. The work was done professionally and efficiently by a qualified and courteous crew. They cleaned up the work area and were very diligent. I highly recommend DZ and will not hesitate to her them again for any/all electrical work. Thank you DZ!

5.0 Barbara M. Smithtown, NY

I was so pleased with The work they did. Definitely would recommend them.


DZ Electric has come to our rescue on more than one occasion over the past two years; has always been quick to respond, super friendly, and more-than reasonably priced. They resolved an issue I was having with a hot tub, replaced an entire electrical panel, installed motion detector lights, and even restored our 30+ year-old landscaping lights because I was too stubborn to find replacementsâ ¦BTW they are beautiful once again! Their most recent visit is a true testament to how GREAT they areâ ¦.it was not to my home. My husband and I had been looking forward to a weekâ s vacation on our boat when its air conditioning failed. After days of having multiple marine technicians on board not able to locate the problem, I decided to call Darren at DZ Electric. He responded immediately and met with us that same afternoon. Our boat was unfamiliar territory to Darren, but he was willing to do whatever it took to help us, and was confident he would find the problem. Darren returned, on time as always, with Rob and Orlandoâ ¦and they immediately got to work. They were laser focused on one thing, getting us back in vacation mode. Not only did they find the problem, they FIXED the problemâ ¦. all within a few hours!! They went above and beyond for us; working in very tight quarters-in extreme heat and humidity, and never complained about it. Even left our boat cleaner than they found it. They salvaged our vacationâ ¦my heroes!! We are very grateful, and would never consider using anyone else for an electrical issue. Thanks guys, you truly are the BEST!!!

Response from Company:

5.0 Carlos R. Smithtown, NY

Rob was professional. He explained exactly what had to be done and how he would do it. Rob also adhered to all the Covid 19 requirements. He wore a mask and maintained his distance. The work done was neat and we were charged a fair price. I will use them again for future jobs and would highly recommend them.

5.0 Kara M. Smithtown, NY

They are professional, thorough, and charged a fair price.

5.0 Carl N. Ridge, NY

Just used DZ for the second time (positive review in itself!). Responded to my call right away, came within a day, and great, fast, professional work like the previous time. Definitely recommend.

5.0 Robert P. Stony Brook, NY

Darren responded quickly to give an estimate, Rob installed new electrical panel, breakers and generator outlet outside. He showed up on time, we are very pleased with the job and very neat. We would recommend DZ and plan on using them in the future.

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.
