"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"

"Needed to expand my electrical panel, add a surge protector, add a wall plug for my television, get the heated floors in my bathroom working, and add recessed lighting to my entire 1st first floor, approximately 700 square feet. Not sure how they got it all done but the work was completed in 1 day. They were professional on time and above all neat. I will definitely use Jason and his crew again."

"I was looking to have some work done on my condo and was hoping to use people from the Waltham area as I wanted to support local businesses and came across PW DiMasi Electric here. Peter and his team were excellent. He was very responsive and scheduled an appointment to give the estimate pretty quickly. When he came to give me the estimate for my living room he mentioned that I should probably also have my dining room light rewired as the building my condo is in is very old so more than likely the wiring was old and not in good shape. At first I thought he might be trying to drum up some extra business (because of bad past experiences with contractors) because my job was so small (it's worth mentioning that Peter was one of the few electricians that I could actually get to come to look at the job in person to give me an estimate, the others I called said the job was too small and not worth their time) but once he took the dining room light down it turns out he was absolutely right about the wiring. I am so glad he was so insistent about replacing it. His guys came right after the plasterer took the ceiling down so it would cost me less to have the work done but unfortunately because of the insulation that was in my attic they couldn't drill holes in the lath for the wiring and boxes so his guys had to go up into the attic which at the time (it was July) was boiling hot . They were always very polite and respectful of my home and did a great job cleaning up after themselves every day. They also always came when they said they would. Peter checked in every few days to be sure I was happy with the work being done. I would not hesitate to recommend using DiMasi electrical and should the need arise in the future, I would use them again."

Small jobs welcome

"I hired Mike to rewire and replace the outlets in my home as well as install brand new lighting, outlets and switches in the finished attic. His workmanship is nothing short of exceptional. It's plain to see that Mike is a professional who cares about his work, and more importantly his clients. His pricing is also very competitive. No need to worry about mile-long contracts and being charged hourly on top of exorbitant fees etc. If you are looking for any kind of electrical work to be done in your home, I highly recommend you give Mike a call or text. I guarantee your experience will be as good as mine was!"

"john was the only electrician who showed up to assess the situation. The others provided estimates sight unseen or through an app which requires multiple pictures. The actual install, especially outside, usually has more complications than anticipated. In the course of performing the work, John made some substantive suggestions based on his experience and the situation at hand. We are very satisfied with the results. I highly recommend him."

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

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
