Knob-and-Tube Wiring Remediation

Knob-and-Tube Wiring Remediation Service

Many pre-1950 Cambridge and Somerville homes still carry original knob-and-tube wiring, which lacks a ground, is buried under decades of attic insulation, and is frequently denied by insurers. We carefully retire and replace these legacy circuits with modern grounded NM-B cabling, working section by section to preserve plaster and original trim wherever possible.

100A to 200A Service Heavy-Ups

Older 60A and 100A services can't support today's heat pumps, EV chargers, and central air. We handle the full upgrade — new meter socket, service-entrance conductors, grounding electrode system, and a modern 200A main panel — including utility coordination with Eversource and all city permitting and inspection scheduling.

Panel Upgrades & Breaker Repairs

Flickering lights, warm breaker faces, or double-tapped lugs are warning signs of an overloaded or failing panel. We diagnose load imbalances, replace FPE Zinsco and other hazardous panels, correct unsafe wiring practices, and rebalance circuits so your electrical system runs cool, quiet, and to code.
