"S & S Eletric was friendly, reliable, knowledgeable, skilled, and well priced. I had a new outlet installed for a garage door opener and a couple of outlets upgraded "to code." The results were perfect. I will call S and S for any future electric work."

"Alex o AP Link contacted us immediately upon receiving the inquiry we submitted. Within days we had an estimate and an appointment. He arrived on schedule and was professional from the moment he arrived until he left. He replaced our 20+ year old exterior light fixtures with the new ones we had purchased. Some adjustments had to be made to the existing wiring in order for all fixtures to be installed properly, which he did. Now our outdoor lights look great and are done right. We will definitely use AP Link the next time we need electrical work done."

"Quality work! Frank came out for three jobs.. Two electrical jobs and one outdoor project. 1) installed new lights in my basement and moved the switches to a more logical location. 2) removed an old lamp post outside and shut off the electrical lines that ran to it. When my wife and I decide what kind of lighting we want outside, we will be hiring him again for the install. 3) removed several small-medium boulders from the property. Also moved a large pile of scrap wood to our burn pile (would have taken me hours). Highly recommended for general handyman work and/or small tractor work outside."

The onsite job was done very professionally and in a timely manner. Mr. Koletas and his co-worker knew exactly what they were doing and handled everything very efficiently. We are very satisfied and can highly recommend their service!"

"When I placed a request for the installation of two outlets on Angie's list, Steve got in touch right away but wasn't overly pushy either [which happens sometimes]. Between the three weeks I first spoke with him and the job, he was professional, informative, and responded to texts quickly and I knew exactly what to expect on-site as well as the cost. He sent pictures and cost of a similar job to help explain the work and the estimate. Steve identified some other issues with my electrical panel and made some small fixes--without increasing the cost of the job--and made some recommendations for me to consider in the future. He was courteous, professional, and seemed to care about the work and about communicating what he was doing and why. I would definitely turn to him first for my next job."

"Craig and his team did a great job of wiring my heat pump and installing a new circuit for the bathroom. Their work appears to be quality, with all the wiring neatly arranged and stapled in place. They were punctual, professional, and friendly, and left the jobsite neater than when they arrived. I would hire them again."

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