JM Electrical Services is a Rockland-based electrician, owned by Marco James Sylvester, with about eight years in business and an active Massachusetts electrician license. The one review on file, from May 2026, describes a genuine emergency: a power line to the customer's home fell down and the utility had to shut off power at the pole until it was repaired. The customer called JM Electric and had power restored within two hours, and said they'd recommend the company '1000%.' There isn't more written history to draw from beyond that single account, though the company also holds an A+ Better Business Bureau grade, even though it isn't a BBB Accredited Business. For an electrical emergency in the Rockland area, the one detailed account here points to a fast, reliable response — it's worth asking for a couple more recent references given how thin the written history is.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from JM Electrical Services, LLC. 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
Recommended 1000%. Today, unfortunately, my electric power line to my home fell down. The power company had to shut off my power at the pole until it was repaired. We contacted JM Electric and within two hours of my call, my electricity was restored. If you are seeking a company that provides exceptional service, I recommend reaching out to them. You will not regret it.
