Straight answer
Yes. In Middlesex County we cover Cambridge, Somerville, Medford, Malden, Arlington, Newton, Waltham and Woburn, with phones answered 24/7. Panel upgrades are a common thread, because older services are being asked to carry heat pumps, EV chargers and induction ranges. Rewiring in triple-deckers and repairs in houses renovated in stages round out most of the work.
Dense inner cities and the suburbs beyond them
The Middlesex communities we serve fall into two rough groups. Cambridge, Somerville, Medford and Malden are close-in and dense, with triple-deckers, two-families and older apartment buildings on small lots. Panels sit in shared basements, meters cluster on one wall, and running a new circuit often means working through occupied units on several floors. Arlington mixes two-families and single-family houses, so a job there can look like either group depending on the street.
Newton, Waltham and Woburn lean more suburban, with colonials, capes and mid-century houses on bigger lots and attached or detached garages. The jobs there tilt toward EV chargers, generator hookups, basement finishing and service upgrades, since there is room to add load and a driveway to charge in. Additions and accessory units are another thread in these towns, and they need a feeder and panel sized for the new space rather than a borrowed circuit.
Triple-deckers and insulation in Cambridge and Somerville
Middlesex County runs from dense inner cities to roomy suburbs, and our work changes with it. In Cambridge and Somerville the housing leans heavily on three-unit buildings, and both cities want more of them built, so meters, unit panels and feeders fill our schedule there. Farther out, the calls lean toward single-family houses adding a heat pump. Mass Save rebates help pay for that equipment, though the qualifying rules are revised each year, so we size the circuits and check the panel while you confirm eligibility.
Why older panels are the bottleneck
Electrification is where much of the new electrical work in these cities starts. A heat pump system, a Level 2 charger and an induction range can each need a dedicated 240 volt circuit, and a house that came with a 60 or 100 amp service often cannot add all three. Before anything is bought, we run a load calculation on the house as you plan to use it. That tells you whether you need a bigger service, a smart panel to manage load or simply a few new breakers.
In multi-family buildings, the question has to be answered per unit and for the building at once. Each apartment may need more capacity, and the service entrance has to carry the total. We plan meter and panel work so units are upgraded in a sensible order, schedule each shutdown with the occupants and file for the permits the work needs in each city, since every community here runs its own wiring inspections.
Middlesex County jobs, from the panel outward

Cambridge, Somerville, Medford, Malden, Arlington, Newton, Waltham and Woburn. These are the communities closest to Boston. If you are just outside them, call and we will tell you plainly whether we can take the job.
Yes, for work that needs one. Each community has its own wiring inspector, so we file where the house is and schedule the inspection there.
Sometimes. It depends on what else in the house is electric. A load calculation answers it, and if the service is close to its limit, load management can sometimes avoid a full upgrade.
Yes. We upgrade meter banks and unit panels, replace old wiring floor by floor and plan shutdowns around the people living in each unit.
