Greenslade Electric works out of 89 Brookline Street in Townsend, and Angi's listing puts the business there since 1999. The jobs on its list are the planned ones: service panel upgrades, generator installs, home theater wiring, and the electrical work behind an addition or remodel. Angi puts its coverage across Middlesex County and lists a state Master Electrician's licence for the business. For a homeowner planning a panel upgrade or a standby generator, it's a reasonable call. Ask for the Master Electrician's licence number and check it against the state register, have the permit and utility coordination named in the quote, and confirm current liability insurance before the work starts.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Greenslade Electric. Use it to sanity-check bids, then get the real number in writing.
Standard receptacle swaps — a new dedicated circuit is a bigger job ($350–$750).
Flush mounts, pendants, chandeliers — hung on existing boxes.
Estimated range
$530 – $1,100
