"John and Ryan came on time to check the electrical connection on our Jenn-Air cooktop. They checked the main box and the electrical box by the cooktop. They diagnosed the issue quickly and fixed the connections with the correct kind of wire connectors. While here they also updated an electrical switch. They did all of this within the original estimate S&S provided over the phone. Thanks!"

"This is the second project we hired Jared for. This was a total bathroom remodel and he updated all electrical outlets, new shower fan, gfi outlets, recessed lighting, electric baseboard with proper breaker. He is always on time. Does clean work. Makes suggestions to save money without compromising safety. Worked with us throughout the project and made adjustments to original design flawlessly. I will be hiring him again in the future for our kitchen remodel. We highly recommend Jared and Southcoast Electrical Services"

"Matt was an excellent fit for our electrical project. I was looking for an electrician to remove knob and tube/rewire our entire house that was built in the late 1800s. He came by the same day that I contacted him to take a look at the wiring. Matt even came back on Labor Day to go through the project with my fiance. He quoted us way less than what other companies quoted for the same quality and job. Matt completed our whole house rewire in less than a week and let us know what was going on every step of the way. I would hire him again. He is extremely trust worthy and willing to work with you on a budget."

"Incredible service from Thomas. He was incredibly professional and fast with his work. I told him I wanted recessed lighting and wires run for a projector I wanted installed. He gave me a full run down of what he planned on doing along with an expected time frame. Thomas got all the work done within just a few hours and at what I feel was a very reasonable price."

"Cotti-Johnson was superb. We had long wanted a permanent generator attached to our house but delayed due to the hassle (buying a generator and then finding all the separate contractors needed to do the electrical and gas work). Cotti-Johnson was one-stop shopping. They did it all, including arranging for the final inspections. They responded to our inquiry right away and within weeks, our generator was fully installed. They also upgraded our electrical panel (long overdue). Kudos to Eric for assessing our needs and E. J. and his co-workers for their efficient and excellent work in installing both the generator and electrical panel."

FAQs for electrical wiring or panel upgrade projects in South Dartmouth, 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.
