What Our Customers Say
Is the Knob-and-Tube in Your Vancouver House Still Live?
Original wiring in a Vancouver house built before 1940 replaced with grounded cable, and a written report of what was live and what was not.
You have seen the ceramic knobs in the attic, or an inspector has named it, and you want it gone. Knob-and-tube has no ground, its cloth insulation cracks with age, its splices hang in open air, and it was never rated to sit under the blown-in insulation that went into most old attics decades later. Knob-and-tube replacement means tracing every run to find what is still live, what is dead and what someone already replaced, then pulling new grounded cable to the same rooms and putting every splice inside a box. The old conductors are disconnected at both ends so nothing dead can be re-energized later. The inspector sees the rough-in before walls close and returns for the final. If the fuse box or an early breaker panel goes at the same time, Clark Public Utilities pulls the meter for that part and sets it again after the inspection passes. You get a written report at the end saying what was found and what was done.

Knob-and-tube is a downtown story here. The city as a whole is only 4.9% pre-1940, but the five tracts within 2.5 km of downtown are 34% pre-1940 and hold 71% of the city's pre-1940 homes — 3,560 of the 87,899 dated units on the assessor's roll were built before 1940.
Signs of Knob-and-Tube Wiring
What Affects the Cost of Knob-and-Tube Replacement in Vancouver
Every old house hides a different amount of original wire, and the tracing decides how big this job is.
How many runs are still live
Tracing sorts live, dead and already-replaced runs; a house still mostly on the old wire is the bigger job.
Whole house or in stages
Doing every old circuit now, or only the rooms you use most, sets very different scopes.
Getting cable to the rooms
Open attics and crawlspaces let cable in from above or below; blown-in insulation or cramped spaces slow the work.
Plaster near downtown
Most of the city's pre-1940 homes sit near downtown, and where cable cannot be fished, their plaster has to be opened.
A box for every splice
Each outlet, switch and light on the old wire gets new grounded cable and a proper box.
Fuse box or early panel
If it goes too, Clark Public Utilities pulls the meter for that part and sets it after the inspection passes.
Rough-in and final
Two inspections, by the city inside its limits or Washington L&I outside them: before walls close, then at the end.
Every job gets a written estimate before any work starts.
