Expert Electrician Services in Boston, Massachusetts

Boston's pre-1940s housing stock is full of knob-and-tube: two separate conductors on ceramic insulators with no ground wire. It worked when the biggest load was a few lamps, but it cannot be buried under insulation, extended, or loaded with modern circuits. Homeowners usually discover it mid-renovation in Dorchester, Roxbury, or Jamaica Plain. We map every active run, de-energize and remove it, and rewire the affected areas with grounded cable. The work is permitted and inspected, and the walls go back together the way we found them.

Homes near the water — East Boston, Charlestown, South Boston — take a constant beating from salt air. Moisture seeps into the weatherhead, the meter socket, and the service mast. The neutral lug corrodes, connections loosen, and the symptoms mimic haunted wiring: flickering lights, random breaker trips, shocks at the kitchen sink. We replace the damaged service equipment with sealed, corrosion-resistant hardware and re-establish solid grounding and bonding. A check every few years keeps it from returning.

Thousands of Boston-area homes still run on 60 or 100 amps of service — plenty when oil heat and a gas range were the norm. Add a Level 2 EV charger, a mini-split system, an induction cooktop, and a home office, and the math breaks. The main breaker trips on winter evenings, or the panel simply has no open slots. We run a full load calculation, upgrade the service to 150 or 200 amps where needed, coordinate the Eversource disconnect and reconnect, and permit and inspect the whole job. Most upgrades also fix old grounding and mislabeled circuits.

Two-prong receptacles are everywhere in Boston's older neighborhoods, and they mean no equipment ground: no protection for your body or your electronics. Current code wants GFCI protection in kitchens, bathrooms, garages, and at exterior outlets, plus AFCI breakers in bedrooms to catch arcing faults. We walk the house, test every outlet, and bring protection current — usually without opening walls. In many cases, GFCI breakers at the panel protect a whole run of old outlets at once, which keeps the project fast and affordable.

Every winter brings the same calls. A branch took down the service drop. Water got into an exterior panel. Or the power returned with a surge that fried the garage door opener and the TV. We respond to storm damage quickly, making the service safe first — downed drops are dangerous until the utility secures them. Afterward we install whole-home surge protection at the panel, replace water-damaged breakers and devices, and check grounding that may have been compromised. A little hardening now prevents the next storm from becoming a shopping trip for new appliances.
