Residential and commercial electrical work, repairs and installations. Panel upgrades, EV chargers, rewiring, lighting, generators — and a 24/7 emergency line that a person actually answers.
One crew for the whole job — from a dead outlet to a full service upgrade, a restaurant fit-out to an EV charger in a detached garage.

“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”
“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.”
Straight answers on panel upgrades, tripping breakers, old wiring, EV chargers and generators.

Read the guideYes. OSB Best Electricians & Electrical Services covers all 511 cities and towns listed on our locations page, from Abington to Yarmouth Port. One number, (833) 652-8933, reaches dispatch for the entire state.
It is. Nights, weekends and holidays, calls to (833) 652-8933 reach a live dispatcher who can send an emergency electrician near you.
Emergency calls are dispatched immediately. Standard service is usually same-day or next-day depending on your city and the time you call.
Flat pricing per job, quoted before the work begins. If we open something up and the scope genuinely changes, we stop and re-quote rather than letting the meter run.
A diagnostic is the work of finding the fault — testing, isolating and tracing. The repair is the fix. We charge a flat diagnostic fee and credit it toward the repair when you proceed.
For panel upgrades, service work, rewires, generators and EV chargers, we file the permit, meet the inspector and hand you the closed permit at the end.
It's most of what we do. Knob-and-tube, cloth-insulated wire, fuse panels and aluminium branch circuits are routine for our crews.
It's an overload, a short circuit, or a ground fault. A breaker that trips is doing its job — the question is what it's protecting you from, and that takes testing to answer.
Do not wait until morning. Our emergency electricians are dispatched across Massachusetts 24 hours a day, seven days a week.
