What does electrical work cost in Greater Hartford?
Typical your area range for this kind of work, from regional averages — not a quote from Onsite Electric 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
