"Tom is excellent. I had him install three ceiling fans in my vacation home two years ago and the work was perfect. He pays attention to detail and the house is spotless when he leaves. This time I upgraded the electrical work in this home. Tom added outlets, repaired ballasts, replaced outdoor outlet covers and added GFI outlets as needed. I also requested outlets into the living room floor and this was done perfectly. Tom noted what electrical work was necessary and completed everything. As usual, the house was spotless."

"Had several problems that were repaired. When another electrical issue arose, they immediately returned and everything went well. Old house with outdated electrical system unfortunately, but I was left with everything working! Extremely satisfied, would use them again when I upgrade my electrical system."

"Came to my house the same day and completed the job. Mike the electrician was a nice guy and did a good job. $200 the first hour and $100 each additional hour. Changed existing ceiling fan, switches and outlets. I already had the parts, took 3+ hours, cost almost $500 with tax. Not sure if this is standard. I called them after another electrician who was supposed to come that day canceled."

FAQs for electrical wiring or panel upgrade projects in Central Islip, 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.
