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 — ungrounded, insulation-degraded, and often buried under attic thermal insulation where it can overheat. We map every run, replace it with grounded copper wiring to current Massachusetts electrical code, and patch access points cleanly, often qualifying your home for updated homeowner's insurance.

Service Heavy-Ups: 60A/100A to 200A

Older Belmont, Watertown, and Arlington homes frequently run on undersized 60A or 100A services that trip under modern loads. We upgrade your service entrance, meter socket, and grounding system to a full 200A panel with room for expansion — ready for EV chargers, mini-splits, and induction ranges — including all utility coordination and permit filings.

✓ Code-compliant installation
✓ Upfront agreed pricing
✓ Workmanship warranty included

Architectural Recessed Lighting

We design and install recessed lighting layouts engineered for your ceilings — IC-rated housings that sit safely against insulation, fire-rated enclosures for floor/ceiling assemblies in multi-family buildings, and slim-remodel trims that mount in shallow cavities common in Boston-area row houses. Dimmer zones and warm-to-cool color tuning available for living spaces, kitchens, and art walls.

✓ Code-compliant installation
✓ Upfront agreed pricing
✓ Workmanship warranty included

Customer Testimonials

Verified Feedback from Neighbors in Cambridge

Real feedback from local property owners who trusted On Time Electrical Service with their mechanical and home services.

★★★★★

“Without a doubt the worst electrician experience I ever had (the electrician in question is named Kristopher Farr). He was explicitly instructed NOT to touch the neighbor's electrical panel (in a shared appliance space) and yet touched it repeatedly without permission from myself or the neighbors. He incorrectly concluded that we had a "mixed panel," which is absolutely not true, and even a novice electrician should have known. …”
