Most Waltham homeowners meet an electrician on the worst day of their month. We try to make that day boring: a clear arrival window, a flat price before we start, and the problem actually gone when we leave.

OSB dispatches across Waltham, its neighbourhoods and the surrounding Massachusetts towns.
The things we treat as non-negotiable on every Waltham job.
Flat pricing quoted before the work starts. Same-day and next-day slots available across Massachusetts.
“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.”
“Fan on a vaulted ceiling that two handymen said couldn't be done. Right downrod, right box, level and silent.”
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”
Most Waltham 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.

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 Waltham 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 Waltham. Call (833) 652-8933 at any hour and a dispatcher will send help.
