Verified record
Jack Griffin Electrical Contracting is a South Yarmouth electrician with 54 tracked permits on BuildZoom, nearly all residential electrical work spread across the Dennis villages, Harwich, Hyannis, Chatham, East Falmouth, Cummaquid, Yarmouth Port and Marstons Mills — a solidly Cape Cod-wide footprint. There's no written customer review on file yet, so there's nothing from past clients to go on beyond the permit volume itself. The licensing picture is worth asking about directly before booking: BuildZoom's own page shows two different pictures of it — one entry it says it verified as an active Massachusetts electrician license, and a separate license number (#25919) it flags as not verified, last confirmed with a July 2016 expiration date. BuildZoom also states Jack Griffin holds five licenses in total, though only these two are itemized on the page. Given that mixed licensing record, it's worth confirming current, active license numbers directly before hiring rather than relying on any one directory listing.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Jack Griffin Electrical Contracting. 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.
