GJS is one of the best contractors we have had the pleasure of working with during the construction of our new home in 2013. They are responsible, knowledgeable and dependable. Gary and his team are very creative and up to date on the latest technology. Their service department is quick to respond and come prepared. I would highly recommend GJS Electric.

I use GJS for all my electrical needs. Gary and his staff are extremely knowledgeable about all things electric and computerized. They also are also very reliable and Gary always returns a phone call. I am a care taker for a few homes on the North Fork and GJS takes care of all of them. I even called once with a down wire at 6pm and Gary came right over to check it out. IN THE DARK! It was fixed by 10am next morning. Can't get better service than that!

Amazing attention to detail and service. GJS was able to give me a full consultation and provide the best and most practical technology solutions for my home renovation. Could not recommend Gary and his entire team more! Service: General construction

Gary and his team are extremely knowledgeable and competent. He has always been available to troubleshoot any problems that are encountered. Gary has done everything from our home theatre to our wifi to general electric projects and we have been happy every single time. I wouldn't recommend anyone else on the north fork.

I first found Gary at GJS when I was completing an addition on my home and the company I had contracted to put in the media system suddenly went out of business. Gary and his team picked up the job. That was nearly a decade ago and they have been providing quality service during multiple system upgrades based on new technology since then. Tim has been our regular technician for the last 5 years or so. He is a great guy and always gets the job done. I appreciate the whole team at GJS and this review is a great opportunity to say thank you publicly.

Used GJS Electric several times. Once for my initial build and then for projects after construction. Their prices are very competitive and they do great work. Every technician that came to my home was very professional and helpful. They have a great team and would highly recommend.

So I rebuilt a home several years ago. I met Gary an GJS at that time. They installed TVs, stereo and the like. Their service, skill and follow up is exceptional. Best experience I have ever had dealing with a trade. Sensational.
