"This summer my wife and I put an addition on our home. We used Shamrock Electric for the electrical portion of the job, and we are so glad we did. From the fist time we spoke and throughout the entirety of the job, Mike was always a pleasure to deal with. Mike took the time to listen to what we wanted and how we would be using the new space that we were building. He offered great suggestions and shared Insight from his experience on how to best achieve what we were trying to accomplish. He suggested electric baseboard heat for the new bathroom that ended up being a great money saving alternative to running an extra loop of plumbing in the foundation. We had some delays in the job due to other parts of the construction process, but Mike was always able to adjust his schedule and get to us for the next step when we needed him. That was a huge relief which we appreciated greatly. With all the crews of workers that we had throughout home over the few months the project took, Mike really left the most lasting impression. That’s why we are taking the time to write this review, he made us feel like our job was important to him. All of his work came out great, the recessed lighting, sub-panel, fans, fixtures, HVAC wiring, security lights and even future circuits for landscape lighting all work well and look clean and neat. We would whole heartedly recommend Shamrock Electric, and if we need any more electrical work will will certainly be reaching out to them again."

"Raul installed a new outlet and dedicated circuit for our smart toilet and hardwired our medicine cabinet — going the extra mile to put the cabinet on its own line for constant power, a trickier job than standard. Multiple holes had to be cut in the ceiling and walls to run wires, but he patched everything back up and cleaned all the dust and debris thoroughly. Both jobs done in just a few hours. He also installed a new light fixture and swapped our old outlet covers for new ones without me even asking, and didn't charge extra for either — small touches that made a real difference. His price was also one of the best out of all the quotes I received, so great value for the quality of work. Before hiring, he answered all my questions by text and call with zero pressure to book. Professional, efficient, great value, and clearly takes pride in his work. Would hire again without hesitation."

"No Shorts Electric helped me bring my 1950's era family home into the 21st century by updating the electrical panel. They are professional & easy to communicate with, plus they did a great job. Finally, I can have all the outlets I need. I am already working with them on a second project!"

"As a Building & General Contractor myself Newgrange electric is one of my best electrical sub contractors. Eddie the owner is very hard working. Always reliable, extremely professional and maintains an office manager Nicole who knows what's going on, on all their projects so you always have someone to contact during business hours. Eddies crew is based of long time employees that are very knowledgeable in there work. Eddie will always get back to you even after business hours, which is not the norm for many vendors. We need more contractors like this. Joe Algeri, Orchard Builders & Construction & Skyline Plumbing & Heating."

"I was truly impressed on how professional and efficient they handled the job. I touched the wrong button on the remote and they came that same night to figure out the issue. I wish I had known of his company before I had major electrical work done beginning of 2025"

"I knew I needed to get a new circuit board because the old one kept blowing out. Antonio Ferrao sent his truck over within hours of my call and his men inspected my old circuit board and showed me the problem circuit breakers and even the discolored area around one which was heating up. They gave me a quote with 10% off if I could pay cash. I hired them. They came the next day, and kindly kept my generator on so I could have electricity while they shut off the main line to change the circuit board. They were fast, efficient, labeled all the new circuit breakers, and cleaned up completely. I would recommend them to anyone."

FAQs for electrical wiring or panel upgrade projects in Garden City, NY

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
