OSB dispatches across Jefferson, its neighbourhoods and the surrounding Massachusetts towns.
The things we treat as non-negotiable on every Jefferson job.
Flat pricing quoted before the work starts. Same-day and next-day slots available across Massachusetts.
“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.”
“Breaker had been tripping for months and two other companies just replaced parts. OSB traced it to a backstabbed outlet behind a bookcase in twenty minutes.”
Most Jefferson service calls are scheduled same-day or next-day, and emergency calls are dispatched around the clock. Call (833) 652-8933 and we'll give you a real arrival window before we hang up.
Yes. The same Jefferson crew that swaps a dead outlet also rewires whole houses, upgrades service panels, and wires new commercial fit-outs. Nothing is too small to book.
Small repairs and diagnostics typically start in the low hundreds; larger jobs like panel upgrades or rewires are quoted flat after we see the work. You get the number before anything starts.
We do. OSB covers Jefferson proper, its neighbourhoods, and the surrounding Massachusetts towns — the whole state is inside our service area.
Older housing stock is most of what we see in Massachusetts. Knob-and-tube, cloth-wrapped wire, fuse boxes and aluminium branch circuits are all routine work for us.
