Knob & Tube Wiring Replacement

What to Expect

An assessment of where knob-and-tube is still active, followed by full or partial replacement with grounded modern wiring and safe disconnection of abandoned runs. Panel and circuit upgrades are included where needed, with documentation for insurance and permits coordinated throughout.

Many older homes in Moncton and the surrounding area still have some original knob-and-tube wiring hidden behind walls or in attics, even after later renovations, and it's a common reason insurance renewals get flagged.

Knob-and-tube wiring isn’t automatically dangerous just because it’s old, but it becomes a real problem when it’s been buried under insulation, spliced into with modern wiring, or left running loads it was never rated for. TLB Electric traces the active runs through the home first, so you know exactly how much is left and where, before any work starts.

Insurance is usually what forces the issue. Many insurers won’t renew or write a new policy on a home with active knob-and-tube wiring, and the ones that will often charge more for it. A proper replacement, documented and inspected, resolves that conversation permanently rather than requiring a workaround every renewal period.

Replacement doesn’t always mean tearing into every wall in the house. Depending on how the knob-and-tube wiring is routed, we can often replace it in stages or target the sections that are actually in use, keeping the disruption and cost proportional to what the home actually needs.
