"George was great. He was responsive, informative, fair, and even got someone else to eventually pay for the work he did! Can not beat it!The electrical panel at my house shorted out and we were without power. This is especially difficult for my family because we have two children and need electricity to get water. We called him the morning it happened, he came out that night to look at it, and by lunch, the next day we had a new panel and power was back on. George also let us know that our panel failed because of faulty workmanship on the part of the utility company and that we should approach them for reimbursement. Our homeowner insurance told us that the utility would never pay and to file a claim. Our deductible was half the total cost of the project and we did not want our rates to go up when we renew. So with George help we submitted information to the utility and requested reimbursement. In less than a week they agreed to reimburse us for the full amount of the cost to replace the panel. They even covered the permitting fee. It was a thousand times easier than I would have ever guessed.We would not even have known it was an option to the hold the utility company accountable, or what information we would need to prove our case without George help. Hopefully nothing ever goes wrong again, but if it does we will definitely hire George again."

"Arete’s team was incredibly professional and efficient. They completed my HVAC job in a timely manner and beat competitor’s pricing. Their team was very respectful of my home and even wiped the floor after each day’s work. Every member of the team was kind and respectful. Will certainly work with them again in the future for any of my HVAC/electrical needs."

"Great job! Worked late into the day to ensure job was done. Total panel upgrade, lights added to the garage and corrected circuit issues in the kitchen including running a new, dedicated line. Clean up couldâ ve been better but thatâ s a minor issue as compared to the job done. Would hire again without a doubt"

FAQs for electrical wiring or panel upgrade projects in Derry, NH

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.
