"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."

"Excellent job. The owner was able to diagnose the problem with our generator. He made a sound recording and video documenting the problem and sent it to the generator company enabling us to receive new parts under the warranty. Mr. Byrne then installed those parts and fixed the generator. We have since used New Grange for all our electrical needs."

"I recently had the pleasure of hiring an electrician to resolve a light fuse issue at my home, and I cannot speak highly enough of the outstanding service I received. This electrician truly demonstrated a remarkable level of expertise and professionalism throughout the entire process. From the moment he arrived, it was evident that he possessed a deep understanding of his craft. He was able identified the problem and wasted no time in devising a plan to address it. What truly stood out was his unwavering persistence in finding a solution. Even when faced with unexpected challenges, he remained dedicated and determined to resolve the issue. His persistence paid off, and in the end, the solution he implemented worked out perfectly. My lights were back in working order, and I couldn't be happier with the results. Not only did he fix the problem efficiently, but he also took the time to explain the issue to me in a way that was easy to understand. Thanks for an awesome Job, Mike!"

FAQs for electrical wiring or panel upgrade projects in Southampton, 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.
