Massachusetts has some of the oldest housing in the country, and plenty of Topsfield 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.
“Two-prong outlets all through a 1920s house. They grounded what could be grounded and GFCI-protected the rest, then labelled everything.”
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
“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.”
Rewiring is priced by circuit count, square footage and access. A small Topsfield 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 Topsfield 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 Topsfield — kitchens, bathrooms and second floors are the usual starting points.
