Knob-and-Tube Wiring Remediation

Knob-and-Tube Wiring Remediation Service

Many pre-1940 homes in Cambridge, Somerville, and Brookline still run on original cloth-insulated knob-and-tube wiring, which lacks a ground conductor and degrades behind plaster walls. We systematically replace it with modern NM-B cable, section by section, while preserving original trim and finishes — and we document everything for your insurer.

Electrical Service Heavy-Ups (60A/100A to 200A)

Today's heat pumps, EV chargers, and induction ranges overwhelm the 60- and 100-amp services common in older Chelmsford and Newton homes. We upgrade your meter, service entrance, and panel to a full 200 amps, including load calculations, utility coordination with Eversource or National Grid, and permitting handled end to end.

Architectural Recessed Lighting Design & Installation

We design and install recessed lighting that respects your ceiling's architecture — from trimless fixtures in Watertown condos to insulated-contact (IC-rated) housings in spaces with minimal attic clearance. Every layout is planned around beam placement, dimming zones, and color temperature so the light flatters the room instead of just filling it.

Panel Upgrades, Repairs & Electronic Components

From obsolete Federal Pacific and Zinsco panels that insurance companies now flag, to flickering circuits and dead outlets, we diagnose and correct the root cause — not just the symptom. As an electronic parts supplier, we also stock and source specialty components for commercial and industrial clients throughout the Chelmsford area.
