Recommended Customer Reviews

Wow, thank you for taking a look at my tenants water heater last minute. You gave me a run down over the phone to save me some money and I really appreciate that. He was fair and honest. Highly recommend!

Larry responded to my request for service in a timely manner. It was in the later afternoon so he troubleshooted the electrical problem I was having. The repair required more time so we scheduled the first available date he had. He was fair in his price estimate.

Quickly diagnosed and fixed the problem with our GFI. Also did a great job adding an indoor electrical outlet.

One of the best electricians on Oahu. We got a few quotes from other electricians and I can say G2 Electric is very competitive in this regard. But where they really shine is with the owner, Larry. What separates him from other electricians is his personality. He's very affable and will take the time to get to know you, answering your questions and explaining everything along the way. We got a new circuit breaker panel, a quick disconnect box and other general electrical work done, all of it done very well and in a timely fashion.
I'll certainly be going to G2 Electric whenever I need any work done, and I'd recommend others to do the same.

Larry was right on time, quickly diagnosed and fixed the problem, and also corrected some incorrect wiring issues. He showed me the issues and explained everything first. Great service, trustworthy, and a reasonable cost = great value in my book. I'll call him again next time I need help!

Larry is awesome! He came in and fixed a few problems caused by another electrician. He explained everything thoroughly and showed me how the work should have been done. In addition, he puts care into his work. He wants his work to look good; he is very professional. In addition, his rates are fair. I recommend him without hesitation.

Larry did a great job making some electrical additions at my business. He's a good hard working smart guy. Principled too. I totally recommend him.

There is a reason Larry has a slew of 5 star reviews. His work looks very clean, he is efficient, on time, and personable. I totally agree with another reviewer - Larry even made friends with our dog!
We had Larry add a ceiling fan, run a new exterior outlet for a beer fridge, and modify an exterior light so that we could add outside bistro lights. (I didn't know we needed bistro lights but Chip and Jo from HGTV have bistro lights, so I found out we ""needed"" them too). I had multiple estimates and went with G2, not because he was the cheapest, but because he took time to understand what we were looking for and he even recommended cheaper alternatives to get what we wanted. Adding the ceiling fan looked like it would be a quick job, but Larry worked his ass off to route the new cable in the wall with multiple cross brace stud breaks.
When I need new electrical work, I am calling G2 Electric! Thanks again Larry. I don't have that beer fridge hooked up yet but when I do, you are welcome to come over and share a cold one.

Larry has completed 2 jobs for us in the last 6 weeks--a larger project where he replaced/repaired/updated most outlets, switches, and wiring over the course of a day and a half, as well as a separate smaller job involving a ceiling fan.
The quality of his work is top notch and completed timely. His response to questions was prompt and communication very easy. That said, what stood out more than anything was his genuinely friendly and laid back demeanor. He's a great guy who does fantastic work. The only negative I can report is that our dog really misses him! He will be our go to guy for all things electrical.

Very accommodating, flexible, friendly and professional. Called Larry for a residential quote and he was there the next week working. We had a few scheduling changes arise and Larry was very flexible and understanding. He is very knowledgeable, easy to talk to, and pet friendly; highly recommend for professional, accountable, reliable electrical service.
