Frank came to our rescue & he is the best! He is very approachable, honest & friendly. In addition, he is also very meticulous in doing his job! He is one of those people who does not cut corners to save time or cost. He does his job very well and even goes above and beyond to make sure the work is done right to help his clients.

Here's the work he did at our house two weeks ago. I attached the before and after... Our power is running fine!

My wife and I had bought our first home, and it had the original electrical panel from the initial construction (1960's!)

Frank quoted a competitive price and did a fantastic installing our new panel and ensured it was up to code and permitted correctly.

It is not often that you come across such genuine workers, and I have been (and will continue) to recommend Interstate Electrical Contractors to anyone who asks.

We needed a Ring installed in our porch. Frank was very busy but we scheduled on a Sunday! Frank was very helpful and informative. He installed it in the quoted time and I felt for a pretty fair price. We will use him in the future for our electrical needs.

Rule of thumb is to get at least 3 quotes on any job and you bean start to slice and dice the priorities. Is it price, quality, or speed? Rarely do you find all 3 in one of the bids so you have to add a new variable: trust. What I found with Interstate is that I only needed 2 quotes before I realized he was the right guy. Frank is different. It was fortuitous that I called him at the right time. He just happened to be driving near my house when I asked him for a quote. He was there in 10 minutes and what he did in the first 5 minutes blew me away. Most service people look at the high level plan and start to price you on how much work they MIGHT do. Frank got on a step ladder and already started to plan it all out. He got his meter from the truck and started to diagnose a couple things. I didn't call him to fix anything, I was just looking for a quote on some work. Two days later and I am sitting back amazed at his quality and work ethic. Give him a call, give him your business. You won't be disappointed.

Frank is very knowledgeable and fair. He responded to my request for a quote within 30 minutes. He quoted me a very fair price and installed a 240V plug and installed my charger for my electric car. Great job and will definitely recommend.

Frank responded to my call and I could sense immediately that he's very willing to help us on an outlet issue for washer/dryer. He came in on agreed time, and immediately diagnosed and fixed the problem. He was very knowledgeable, professional, and has great attention to detail. He went out of his way to make sure that our electrical panel is safe, clean, and neat. He fixed whatever were tangled, or had exposed wires. He also patiently knelt to fix a broken outdoor GCFI outlet. I also appreciate his very detailed explanation to my questions about electricals, rewiring, and safety concerns. His price was very reasonable and unbeatable.

I would definitely re-hire him in future projects, and I would highly recommend him to anyone who need help on anything electrical.

We were having issues with a circuit in our house, and an electrician was able to come out within a couple hours. The electrician was very knowledgeable and professional. It turns out the fix was embarrassingly easy, so he gave us a discount on the fee for coming out and troubleshooting. He also took the time to help my husband make our electrical box safer when he could have just left. We will definitely call them back when another issue comes up!

Frank is a professional and very friendly at the same time. Recently he did a buss bar upgrade, upgraded some breakers, installed an Electrical Vehicle charger, and installed a transfer switch for a my generator for a great price. We worked over a few weeks coordinating parts, edison appointments, and making sure everything was compatible. He did a great job. Thank you Interstate and Frank.

We lost power to half of our house outlets and Frank came out and solved our issue. He was honest and very knowledgeable. His work was very clean and professional. He was punctual and his pricing was very reasonable. I would definitely recommend his services and will call him again for any future repairs we may need
