"Matt and his team were professional and friendly. He communicated well and was punctual. I had him put in an EV Charger out to my driveway and also needed to upgrade my electrical wiring which became more difficult than expected but Matt honored our agreed contract and had even saved us some money on figuring out a better solution. I highly recommend Matt and his team for any electric service."

"Peter and his team did a panel upgrade for us when we bought our house in 2021. They completed tidy and well-labeled work on a tight deadline, exactly as planned, on one of the hottest days of the year. I was really impressed at the time with the clear communication about when they'd do different phases of work, what we needed to arrange with the town electric company, etc. More recently, one piece of conduit came unglued and they came by to fix it almost immediately, free of charge. I'm really impressed with this crew's standards."

"It turns out I just needed to replace a breaker that was a much cheaper repair since my system was already upgraded to 100 amps. No need to replace the panel. Brandon explained this well, worked efficiently and professionally."

"New washer was causing circuit breakers to flip on my electrical panel. Mr. Handyman, who does my home repair and maintenance, referred me to McCurdy Electric emphasizing that they are the best in the business. Contacted McCurdy Electric and from that first phone call was in great hands. From Judy in the Office to Owner John who came out to meet and prepare estimate, professional and kind all the way. Logoed truck, always on time. Upgraded service to 100 AMP. Shebeeb and Brandon dug the trenches, ran the wires and quite honestly worked hard getting me back up with electricity before they left. McCurdy Electric even pulled the required permits and met with the City Inspector at my home. Just sat back with a book and let the professionals do their magic. Will not hesitate to contact them the next time I need electrical work done. Five Stars. --Charlene in West Peabody, MA"

"We hired Chris to help prepare our kitchen for an electric range, which required a new high-voltage outlet connected to the electrical panel in the basement. He was responsive, clear, and gave a transparent estimate immediately. On the day of the job, he was punctual and thorough, and completed the task before the estimated timeframe with high quality work and clear explanations. He also fit in time to move an outlet for a dishwasher, which we had not previously know we would need, and kept the final total close to the original estimate including the new project. We would certainly use Chris again for electrician needs at our home, and appreciate his expertise."

"The job went perfectly. Stephen and Ashlee were amazingly professional and knowledgeable. They upgraded my house to a 200 amp panel, with completely new interior box and exterior meter (including wall modifications), and new grounding and protection. In addition they installed a few LED lights around the house as upgrades. They were finished in three days, as quoted, and were on time and efficient every morning. The inspector even went out of his way to comment what a great job was done. I will absolutely be using Cotti-Johnson again."

FAQs for electrical wiring or panel upgrade projects in Watertown, MA

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.
