Hiring a Electrical contractor in Dedham
Electrical work in Dedham requires a permit under 527 CMR 12.00, the Massachusetts amendments to the National Electrical Code, performed by a licensed Journeyman or Master electrician. Permits are filed with the Dedham Building Department and the town wiring inspector inspects the work before it's energized. Panel upgrades, EV circuits, generators, and rewires all need permits; like-for-like device swaps generally don't. Properties in Dedham's historic districts around the square may face additional review for visible exterior changes such as a relocated meter or service mast.
Dedham pricing reflects the inner Boston metro market. A 100A-to-200A panel upgrade typically runs $2,800–$5,200, more when an old service entrance or meter socket needs rebuilding. A Level 2 EV-charger circuit usually lands at $1,000–$2,300 depending on the run to the garage. Knob-and-tube rewiring is priced by accessibility and often falls between $8,000 and $18,000 for a full house. A whole-home generator with a transfer switch generally runs $8,500–$15,000 installed.
Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential electrical work; ask for the registration number and check it before paying a deposit.
