Knob and Tube Rewiring Across Taunton, MA and All of SE Massachusetts

The short version: Knob and tube wiring was standard from the 1880s through the 1940s. It uses ceramic knobs to secure the wire and ceramic tubes where it passes through wood framing. The conductors are ungrounded, cloth-wrapped, and designed for electrical loads that modern households exceed before breakfast. A single air conditioner, EV charger, or induction range can push it past what it was ever built to handle.

Why insurers are pulling back: Massachusetts homeowners insurers have become increasingly reluctant to cover homes with active knob and tube wiring, and some will simply not write a new policy. When they do, the premium is higher. Tyler’s team hands you a completed permit and final inspection paperwork that you can send directly to your carrier to document the replacement. That paperwork is part of the job, not an add-on.

Hidden knob and tube is the real problem: The most dangerous scenario is not the original wiring doing what it was designed to do. It’s the original wiring buried under insulation added decades later. Knob and tube is designed to dissipate heat through open air. When an insulation contractor buries it in blown-in cellulose or fiberglass batts, that heat has nowhere to go. Tyler’s walk-through always includes attic and crawl space inspection before a single quote number goes on paper.

The grounding gap: Modern appliances, GFCI outlets, and arc-fault circuit interrupters all depend on a grounding conductor. Knob and tube has two wires: hot and neutral. That’s it. You cannot simply install a three-prong outlet on a two-wire system and call it done. Tyler replaces the wiring and installs properly grounded circuits throughout, so the outlets your family actually uses are protected the way current code requires.

The 1920s two-family in Taunton: Double-decker homes built before the Depression era frequently have active knob and tube on the second floor while the first floor was updated at some point. Tyler sees this constantly: a panel that was replaced in 1980 with new circuits run to the first floor, but the second floor and attic retained the original wiring. The mixed system is actually more dangerous than all-original wiring because the new panel can push more current than the old circuits were ever rated to carry.

The Brockton three-bedroom with blown-in insulation: Weatherization programs over the years have pushed a lot of insulation into attics that still have active knob and tube. The energy savings are real, but the buried wiring is a fire risk. Tyler coordinates with homeowners and, when necessary, with Mass Save program administrators to sequence the rewiring before or alongside insulation work so both projects close out clean.

The Fall River Victorian with prior splices: Older homes often have decades of DIY additions: knob and tube extended with early plastic-jacketed wire using wire nuts in open boxes, or buried in walls with no box at all. Tyler’s walk-through documents every visible splice. During the rewiring, the crew pulls all of it, not just the sections that look original. A partial rewire that leaves DIY splices in the walls does not satisfy a home inspector or an insurance underwriter.

The Attleboro ranch with an older panel: Ranch homes from the 1940s and 1950s sit at an interesting transition point: some were wired with knob and tube, some with early plastic-jacketed cable, some with a mix. Tyler identifies exactly what’s present before scoping the job. Where knob and tube and early cable share the same panel, both often need attention. The panel itself frequently has issues: double-tapped breakers, mismatched wire gauges, or fuses that were upsized to stop nuisance trips instead of fixing the underlying overload. The rewiring job addresses all of it.
