I rarely take the time to write reviews. But I must say, August Costanzo, his son who works with him, and their secretary Lisa have been an absolute pleasure to deal with. I received prompt replies after normal business hours, and August even sent me an unprompted e-mail on the 4th of July asking me details of the EV charger I needed installed. I had a small issue with paperwork on the install day, and not only did Lisa follow up on the paperwork, it was all ready and the job was done the next business day, with absolutely perfect work and a very clean install - and I take my electronic installs seriously. August gave me the most reasonable estimate out of 4 estimates, beat the next lowest estimate by 35%, and did fantastic work, all while taking care of the permits. Lisa, his secretary, will bend over backwards to help you, also responding to calls after hours. I can NOT recommend Costanzo Electrical enough. I wish I could give TEN stars.

Costanza Electric provided outstanding service for my electric circuit upgrade and EV charger installation. They offered reasonable pricing, flexible scheduling, and ensured thorough inspections before considering the job complete. August Costanzo's genuine professionalism shines through, making them my top recommendation for any electrical needs.

Costanzo electric was terrific! The estimate for the service was very reasonable considering the area and given by August the owner. He was able to come within a week and three men did the work. The men were clean and efficient and removed one fan and installed two new fans perfectly aligned. They cleaned up any mess and reviewed with me what they did and asked if I was happy. Great to find a reputable contractor and someone I can rely on going forward

Initially, they had come in to fix 50+ bulbs in complex lighting fixtures and later discovered that ballasts needed to be replaced as well. They were able to get the job done in 2 days and August also helped me with a last-minute electrical problem. They are very friendly people with great customer service. I would definitely recommend if you’re looking for reliable electricians who actually know what they’re doing!

August did an expert job. He is cordial, professional and skilled at what he does in the sense that he had to change a light fixture from 1920 to a more updated one and took great care with the installation. I would highly recommend and for sure, call again for my electrical jobs.

It was a pleasure working with August and his workers. He explained exactly what he was going to do and did exactly what he explained to me. He worked efficiently and he definitely knows what he is doing. The best contractor I ever had in my house. They cleaned up after themselves and even used the basement door so as not to track footprints in the house because it turned out to be a rainy day. I asked August if he could do a few things for me that needed to be done and was expecting to pay the extra money. August didn't change the original quote and I was surprised. That has never happened to me. I would definitely recommend him for electrical projects in the home and I definitely would use him again without hesitation. The project took just as long as he said it would. Definitely call him for any electrical projects you have. His prices are reasonable, if you have any electrical work done in your home before, you will know this. Great experience.

He was punctual,professional and friendly he arrived the next day after we spoke which was 10/3/19. He also offered me a discount when I had 2 boxes to do instead of one. He told me from the start he was working on another job which was ok. He had to get permits and said it would take at least 3days to get them. I spoke with him on the 7th and he said it just takes time for them to be processed. I called him again on the 9th and he told me the same thing. Two days Iater on 11th I called the Permit dept. and there was no record of anyone applying for a permit to perform the work for the fuse boxes at my address. When I confronted him about it he got very angry and our conversation ended , not on a good vibe.
Response from Costanzo Electrical & Mechanical, LLC

"After meeting with you on 10/3 and providing you an estimate you committed to the job on 10/7 after adding the extra work to be done (2nd panel). I said it would take me several days to get the permits filed. I was able to get the permits filed and paid for 4 days from you confirming the job. While I’m sorry you we’re not happy with the level of service I tried to provide, I do hope you find an electrician that can better meet your needs to complete the job."

Very well - Gave very good price. Made recommendation for conduit instead of just line on side of house. Work is clean and neat. New panel with tons of space for additional circuits when we finish basement. Just passed inspection today. Will use again.

Contacted us morning of request. Advised to replace since long past life expectancy. Provided quote and estimated time of installation. Contacted us to let us know arrival would be a little late (much appreciated!). Replacement was done efficiently and quickly. Delighted with replacement, responsiveness, and quality of work. Would definitely use again as well as recommend to others.

The 2 man team quickly diagnosed the problem to be a bad circuit breaker switch in the electrical box. Within an hour they had everything working. They were very professional and worked quickly to solve and fix the problem.

Fantastic. Guys were prompted, showed up on time, figured out the issue (they didn't need to run a new cable, the previous electrician screwed up) and fixed it quickly, all with a very reasonable fee. Definitely would hire again.
