"Mike from No shorts electric was very prompt. He carefully inspected the entire electric panel and said that the source of the odor was something other than electrical. He was very methodical and courteous. He did not charge anything, even for a service call or for his time/travel. That was so pleasantly surprising. WIll gladly use him again and highly recommend him to others."

"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 needed electrical work done in my home. He did an excellent job. He was professional and polite, and very neat and efficient work was done. The work came out great and will definitely rehire in the future. I'm glad I found a reliable electrician in Valley Stream. If my friends need an electrician, I will definitely tell them to call."

"Very honest company. They saved me money. I am having more work done with them. I just used this company again on 6/12/24. They came and ran a whole new system for me for my garage. They had to dig in the ground to run wires throughout my house and back to the garage, but I have a dedicated system for the garage only that will not interfere with anything in the house. This is a plus. They spent a whole day and took their time to do the job correctly. I am satisfied with what they did. The only concern I had was after they dug up my ground, they did not pour cement down to cover up the large, large hole that's in the backyard. So now I have to get another company to come in and pour concrete to fill in the hole. However, the man did tell me that he informed my husband about this situation and like a typical man (LOL), my husband did not inform me that we would have to call in another company to do this work now. So now this is another expense and another company I have to deal with. But Duffy Electrical is a very good company and they take pride in their work. I am happy with my garage having it is own dedicated system. Now, I do not have to be afraid about loosing electricity in my house while out in the garage. I can also add on to this system as we will later on. I recommend this company highly. You will be satisfied and happy. The price was a little steep but it's worth it."

FAQs for electrical wiring or panel upgrade projects in Rockville Centre, 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.
