If your Woronoco home still runs on a fuse box, a 60 or 100 amp service, or a panel brand that insurers flag, an upgrade is the single biggest electrical improvement you can make. OSB handles the permit, the utility coordination and the swap.
“Whole-house LED retrofit across our warehouse. Our lighting bill dropped and you can finally read labels on the top rack.”
“Fan on a vaulted ceiling that two handymen said couldn't be done. Right downrod, right box, level and silent.”
“We had knob-and-tube in the attic and our insurer was getting nervous. They rewired in stages so we never lost power for more than a few hours at a time.”
A straightforward 100 to 200 amp upgrade in Woronoco usually lands in the low thousands. Cost moves with mast height, meter location, grounding work and whether the utility needs to reset the drop. You get a flat quote before we start.
Most Woronoco panel swaps are a single day, with power off for part of it. Larger service upgrades that need utility scheduling can run into a second day.
Yes — service and panel work is permitted and inspected in Massachusetts. OSB files the paperwork and meets the inspector so you don't have to chase it.
For nearly every single-family home, yes — including one EV charger, a heat pump and an induction range. Very large homes or two EVs sometimes justify 320/400 amp service.
Regularly. Fuse-to-breaker conversions are one of the most common jobs we run in older Woronoco housing stock.
