Verified record
Typical Greater Boston range for this kind of work, from regional averages — not a quote from S & T ELECTRICAL. 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
Typical electrical project around $820
Twenty-two years in business, by its own count, S & T Electrical works out of Tyngsboro on residential and commercial jobs — lighting, wiring, and complete electrical system installations. The company's site offers free estimates and lists a service area running through Acton, Billerica, Chelmsford, Concord and Dracut. Its Better Business Bureau page carries an A+ grade. On Google it sits at 2 stars from 4 ratings, and a May 2026 reviewer there complained about aggressive and careless driving by an S&T vehicle in Medford. For wiring or a lighting install in the towns it names, the free estimate is a low-cost way to start — confirm your town is one it covers, and what the estimate includes, before booking.
This is a review of the S&T -4 ford vehicle that just ran two parent cars filled with day care kids off the road in Medford. Very aggressive and careless driver that almost caused a multi car accident . Drive safer .
