Working in Tewksbury
Your local electricians for Tewksbury.
Tewksbury sits where I-93 and I-495 meet, which makes it an easy commute and a busy town. We work in neighborhoods all over town, from the streets near the town center to the newer developments off Route 38 and near the Shawsheen River.
Generator work has been a big part of our Tewksbury business. Our blog includes a Tewksbury guide to professional generator installation because we get so many questions about it here.

Homes & buildings in Tewksbury
Colonials, ranches and storm season.
Much of Tewksbury’s housing is single-family homes built from the 1960s through the 1990s, many with 100- or 150-amp services that were generous when they went in. Today those same homes are adding heat pumps, EV chargers and home offices, and some are running short on capacity.
Like much of the Merrimack Valley, Tewksbury loses power in big storms. Homeowners here often ask about standby generators with automatic transfer switches, and about the safest way to use the portable generator already sitting in the garage.

Before you start
Planning a project in Tewksbury.
If a generator is on your list, plan it before winter. We’ll look at where the unit can sit with safe clearances, whether gas is available or propane makes more sense, and how the transfer switch fits with your existing panel. Pairing a generator with a panel upgrade or surge protection often saves on labor.
For EV owners commuting on I-93 or I-495, we check the panel before installing a Level 2 charger and plan the circuit so a second EV can be added later without starting over.
Tewksbury FAQ
Electrical questions from Tewksbury
How big a generator does a Tewksbury home need?
It depends on what you want to power. We do a load calculation and help you choose between whole-home and essential-circuit coverage.
Do you handle permits for generators in Tewksbury?
Yes. We file the electrical permit and coordinate the inspection.
Can you install a transfer switch for my portable generator?
Yes, or a panel interlock, whichever fits your panel and budget better.
Should I upgrade my panel before adding a generator in Tewksbury?
Not always, but it’s worth checking. If your panel is old or full, upgrading at the same time can simplify the transfer switch installation.
