I had the wonderful experience using an electrician named Frank Chiavarini from Interstate Electrical Contractors. He has been self-employed for over 30 years, does the work himself and takes pride in what he does. He put up a ceiling fan for me that took sometime to do, and switched out switch plates and internal pieces that needed to be replaced. He is a perfectionist and I could not be happier. Iis always so stressful getting someone new not sure how they will interact with you or the project. I can not recommended him highly enough. It's just so nice to get a old-school attitude and old-fashioned work ethic. He even offered some other advice about our current bulbs and my hard-wired smoke detector system which he will be back to do for me soon. Please give him your business, you will not be disappointed.

Thanks Frank for your honesty. He checked out our panel and verified everything was good and didn't push for unnecessary repairs. He took the time to talk about some other projects I had around the house and gave great recommendations. If you are looking for really nice, honest electrician, Frank is your guy!

I called Frank (owner) to try to find out and fix a problem left hanging by a previous electrician who never came back as promised to finish the job. All circuits blew out in two rooms plus the main outlet in my bathroom. The previous electrician said he'd try to find the problem by replacing all of my outlets in the house. I mentioned this to Frank and he wasn't too keen about that. It would be expensive and possibly take much more time if his hunch wasn't correct. I've watched plumbers, Handymen, and electricians many times being a homeowner. I've never seen any work so methodically to find a problem. As Frank checked a couple of outlets he would think about some possibilities before jumping into checking and changing every outlet in my place. I was emotionally prepared for hours of work and a very large sum of money going from my bank account to his before he even arrived. After checking a few outlets he asked if I had an outlet behind my huge dresser. I did and he had his reason for asking and I won't go into great detail why but he was correct in his hunch. He thought there was a high chance the problem was with that outlet and voila. The socket behind the heavy dresser, although still working, was the problem after all. He educated me, fixed the problem in a very short time and left my bank account pretty much intact. He's a very personable guy who is VERY fair about the price. I even posted my story on Facebook and informed some neighbors about this find. His number is now on my phone directory.

We have an older home and noticed our lights flickering. After getting a quote for $5-$7K to replace our electric panel from a company that clearly is in it for the upsell, Frank came by and got right down to business. He handled the problem efficiently, quickly, professionally, and with a know-how that only comes with years on the job. He didn't try to sell us something we didn't need and made sure our panel was completely safe and operational. Thank you, Frank!

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.
