Hiring a Electrical contractor in Lexington
Electrical work in Lexington requires a permit under 527 CMR 12.00 and a licensed Journeyman or Master electrician, with the town wiring inspector reviewing and inspecting. A service upgrade gets a rough and a final, and Eversource coordinates the reconnect. Exterior changes on homes in Lexington's historic districts near the Battle Green may need additional review before a meter relocation or generator pad. Only like-for-like device swaps skip the permit. Your electrician files it and books the inspections.
Lexington runs at the higher end of greater-Boston rates. A 100A-to-200A panel upgrade typically runs $3,000–$5,500, more for a 320A/400A service on a larger home. A Level 2 EV circuit is usually $900–$2,300. A whole-home standby generator with an automatic transfer switch generally runs $11,000–$19,000 installed. A knob-and-tube rewire in an antique center home can reach $14,000–$30,000.
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.
