Massachusetts has some of the oldest housing in the country, and plenty of South Yarmouth homes are still carrying current on wire installed before the war. OSB rewires houses in stages so you keep living in yours while the work runs.
“Our panel was original to the house and completely full. OSB upgraded us to 200 amp, pulled the permit, met the inspector, and left the basement cleaner than they found it.”
“Bought an EV and had no idea what my panel could handle. They did the load calculation, told me straight that I had room, and installed the charger two days later.”
“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.”
Rewiring is priced by circuit count, square footage and access. A small South Yarmouth home may be a five-figure project; a partial rewire of a kitchen and bath is a fraction of that. We walk the house and quote flat.
Almost never. We work zone by zone so you keep power, heat and a working kitchen through the job.
Existing knob-and-tube isn't automatically illegal, but it can't be extended, it has no ground, and insurers increasingly won't write a policy over it. That's why most South Yarmouth owners replace it.
Less than you expect. We fish cable through bays, closets and chases and cut small, patchable access points rather than opening whole walls.
Yes. Partial rewires are extremely common in South Yarmouth — kitchens, bathrooms and second floors are the usual starting points.
