Electrical Service Upgrades in Middleton, MA
Most of Middleton’s housing stock went up from the 1960s onward, on the bigger lots you’d expect out here, and a lot of it was wired for a 100 amp service that made sense at the time. Now those same houses are getting EV chargers in the garage, heat pumps replacing oil furnaces, and finished basements with their own circuits, and the original service was never sized for any of it.
Why Middleton Homes Need This
Middleton doesn’t have the dense older housing stock you’ll find closer to Salem, so you’re less likely to run into knob and tube wiring here, but 100 amp services are still common on homes built through the 1970s and 80s, and some of the older farmhouses and colonials scattered around town do carry Federal Pacific Stab-Lok or Zinsco panels that were standard issue decades ago and are now known to fail to trip when they should.
What’s changed is demand. A Level 2 EV charger alone can pull 40 to 50 amps on its own circuit. Add a heat pump system, a finished basement with its own subpanel, maybe a hot tub or a workshop, and a 100 amp service gets maxed out fast. Middleton’s larger lots and newer additions mean more of this kind of load stacking than you’d see in a tighter, older neighborhood, which is exactly why this is one of the more active service-upgrade markets in our coverage area.
What the Work Involves
A service upgrade from 100 to 200 amps touches everything from the utility connection down to your main panel. Brandon starts by sizing the job: checking your existing meter base, mast, and service entrance conductors, and confirming what the new load actually requires. For most homes going to 200 amps, that means a new meter socket rated for the higher amperage, heavier gauge service entrance cable, and often a new or upgraded weatherhead and mast on the roof or side of the house.
The utility owns the drop, whether it’s overhead or underground, and they have to disconnect power before any of this work happens and reconnect it after. Brandon’s crew handles everything from the weatherhead in: the mast, the meter socket, the main panel and breakers, and all the connections in between. Power is off for the actual swap, and everything gets landed, torqued, and labeled before the inspector or the utility sees it.
What It Costs
A straightforward 100 to 200 amp service upgrade in Middleton typically runs {PRICE_LOW} to {PRICE_HIGH}. Where you land in that range depends on whether it’s overhead or underground service, how far the mast has to run, whether the meter location is moving, what shape your existing grounding is in, and whether the utility requires any additional work on their side before they’ll reconnect. A house with an underground service and a meter that needs to relocate costs more than a straightforward overhead swap in the same spot. Brandon walks the job with you and gives you the number before anything gets scheduled, not after.
How Long It Takes
The physical work, once the utility cuts power and Brandon’s crew is on site, usually takes a matter of hours. Where it stretches out is the scheduling around it. The utility has to disconnect before work starts and reconnect after the local inspector signs off, and depending on how busy the utility and the inspector’s office are, that coordination can add a week or two to the calendar even though the actual labor is fast. Brandon builds that timeline out with you up front so you’re not left guessing when the power will actually be back on for good.
Permits and Inspection
This is permitted work in Massachusetts. There’s no version of a legitimate 100 to 200 amp service upgrade that skips the permit or the inspection. The permit gets pulled with the local building department before the job starts, and once the new service is installed, a licensed electrical inspector reviews the work before the utility will reconnect power. That inspection is a real backstop, not paperwork for its own sake. It’s also the clearest way to tell licensed work from someone doing it off the books.

Common Questions
How do I know if I need a service upgrade instead of just a panel upgrade?
If your panel itself is in decent shape but your main breaker or meter is rated for 60 or 100 amps and the utility drop feeding the house is undersized for what you want to add, that's a service upgrade. Brandon checks the size of your service drop, your meter base rating, and your main disconnect before recommending anything. Sometimes a panel swap is enough. Sometimes the whole service, from the utility connection down, needs to move to 200 amps.
Will National Grid or the utility need to be involved?
Yes. The utility owns the drop or the transformer connection and the meter. On a service upgrade, they usually need to disconnect power before work starts and reconnect after the inspector signs off. Scheduling that coordination is part of what Brandon handles, so you're not calling the utility yourself trying to figure out timing.
Do I need a permit for a 100 to 200 amp service upgrade in Middleton?
Yes. This is permitted electrical work in Massachusetts, full stop. The permit gets pulled before work starts, and a local inspector reviews the finished work before the utility reconnects power. That inspection step is one of the clearest ways to tell a licensed job from unlicensed work.
How long will my power actually be off?
The outage itself is usually a matter of hours, not days, once the utility disconnects and Brandon's crew swaps the mast, meter socket, and panel. The scheduling around it, getting the utility disconnect and reconnect lined up with the inspection, is what can stretch the calendar out over a week or two.
Can this wait until I actually buy an EV or heat pump?
You can wait, but a lot of Middleton homeowners find it easier to do the service upgrade once and add circuits for the charger, heat pump, or finished basement as those projects come up. Otherwise you may end up opening walls and pulling permits twice for work that could have been planned together.
