OSB dispatches across Cambridge, its neighbourhoods and the surrounding Massachusetts towns.
The things we treat as non-negotiable on every Cambridge job.
Flat pricing quoted before the work starts. Same-day and next-day slots available across Massachusetts.
“Sold our house and the buyer's inspector flagged eight electrical items. OSB fixed all of them in one visit and wrote it up so we could close on time.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“Storm took out our power for four days last winter. This year we have a standby generator that started itself while we were asleep.”
Most Cambridge 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 Cambridge 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 Cambridge 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.
Yes — OSB runs a 24 hour emergency electrician service in Cambridge. Call (833) 652-8933 at any hour and a dispatcher will send help.
We cover Cambridge and its neighbourhoods, plus every surrounding town in Massachusetts. If you can find your town on our locations page, we dispatch there.
Three legitimate fixes, one of which is far cheaper than a rewire.
