Verified record
Twenty-seven years in business, by its BBB profile, and 238 permitted electrical projects logged on BuildZoom — David K. Hamner Electric is a sole proprietorship working from Longfellow Road in Waltham. The Better Business Bureau grades it A+ and lists the work it takes on as new electrical installation, service, repair, maintenance and upgrades. BuildZoom lists a Newton electrician licence, #40074, for the business; check where that one stands on the state register before you book. It suits a homeowner who wants one electrician for the panel or service work and the small jobs after it. Get the scope and price in writing, confirm the licence, and ask for a certificate of insurance before the work starts.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from David K. Hamner 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
Typical electrical project around $820
