"We had a list of items that needed to be completed (driveways lamps posts/lighting, cathedral ceiling fan, various fixtures, etc.) and a couple of more involved projects we were thinking of doing, like a hot tub installation. Harland Electric was responsive, prompt, courteous and professional throughout the entire process—from initial contact, estimate and work. They itemized each of the projects so that we could pick and choose the work that needed to be done, and were helpful in detailing the complexities of certain projects and weighing the pros and cons of having electrical work done. During the course of coming to the house and knocking every item off of our list (which took 1.2 days worth of work/time), they also alerted us to an electrical fire hazard for an outdoor flood light that another electrician from another previous company just left and said was okay. They replaced the entire light and wiring and now it looks great the way it illuminates our side yard! We even overpaid at the end of the project and they immediately let us know! They are scheduled to return in the spring to install a pool heater and we have no doubt they will do a great job. Overall, great service, highly ethical company and good value overall. Highly recommend!"

"Our project was a panel upgrade and generator install. From the first point of contact through point of completion Kevin's level of professionalism, customer service and follow through were beyond exceptional. He is very skilled and knowledgeable in the electrical field. He was able to answer all of our questions and we knew we made the right choice. Once the scope of work was determined and a date/time established he arrived on time and completed the work promptly and neatly. We are extremely pleased with Kevin's work. In fact we have other electrical projects planned in the near future and we will be reaching out to Kevin. For anyone searching for an electrician Kevin is the right person and I can assure you that you will not be disappointed."

"Dave was great! Top quality work at a fair price. I needed a degraded riser cable that feeds the meter box outside the house replaced. Another company gave me a ridiculous quite which included current code updates that said I needed. My town electrical inspector said that none of those were required for a simple riser cable replacement. I highly recommend Lanzillo Electric!"

"I have called Michael into a few projects. He offers an array of services from wiring a full house to simple fixtures. He recently separated a four family offering all new meters and main panels. When it comes to electrical I don’t think there is anything he can’t do. Without hesitation, I recommend him to all."

"Just call these guys. There. Done. James and his brother, Daniel, came out to move a wall installed TV. I wanted it lower and the job entailed moving two outlets lower as well, then patching the drywall. These two were great: very knowledgable, incredibly professional, highly skilled, very friendly, cleaned up over and over while working (the mom in me LOVED that) and charged a very fair price. I felt they went above and beyond what most installers would do and they went above and beyond to make sure I was happy with the job. Even better? They will come weekends and evenings at no extra charge. I highly recommend them. Just had to come back and say that, because Daniel did such a fabulous job repairing my drywall and painting after my TV was moved, I hired him to come and repair drywall with water damage and repaint that as well. His work is invisible!! He did an awesome job!! Swift, impeccably clean, VERY reasonably priced. I don't always go for the cheapest estimate because I'm fearful of sloppy work. Daniel gave me the best estimate as WELL AS the best work! I had to go to work as well as run errands while he was in my home. I trust him implicitly."

"Michael has been wonderful from start to finish. Even when I was experiencing difficulties with the pool company to come out and install, that put him on hold from getting his electrical part done. Michael was on stand by and ready to come out when I needed him. Super professional, gets right back to you with any questions/concerns, on time and very patient. Will be hiring for future electrical projects!!!"

"On a routine inspection Milltown found that I had water coming into my breaker box from outside the house. They gave me several options and I decided to upgrade my box in addition to sealing the area from further water damage. They were very professional and the project looks tidy. They addressed extra issues they found during the upgrade and straightened out all the wires. I would use them for future projects."

FAQs for electrical wiring or panel upgrade projects in Groton, 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.
