Knob & Tube Wiring Replacement Alderwood
Alderwood is known for its quiet residential streets, generous lots, mid-century bungalows, detached homes, and a growing mix of townhomes and newer infill construction. Many of the older houses in the neighbourhood still hide original knob and tube inside attics, basement ceilings, and finished wall cavities. Our ESA-licensed electricians replace that outdated wiring with a modern code-compliant system so your Alderwood home is safer, easier to insure, and ready for current electrical demand.

Why Knob & Tube Wiring Must Be Replaced
Across Alderwood, especially near Brown’s Line and the Evans Avenue corridor, many older homes still carry electrical systems that were installed long before modern kitchens, HVAC equipment, and home-office loads became normal.
No Ground Wire
This older wiring method only uses hot and neutral conductors, which means your outlets and appliances miss the grounding protection expected in a modern electrical system.
Deteriorating Insulation
The old rubber and cloth covering often dries out, splits, and crumbles after decades in service, leaving energized conductors more exposed inside concealed framing spaces.
Overloaded Circuits
These circuits were not designed for present-day cooking equipment, portable air conditioners, charging devices, entertainment systems, and the number of electronics used in a typical household now.
Insurance Cancellation
Active knob and tube regularly causes problems during insurance renewals, home purchases, and refinancing, and owners are often told to replace it to keep standard coverage in place.
Buried by Insulation
Knob and tube depends on open air around the conductors to cool properly, so once attic insulation surrounds active runs, heat can build up in conditions the system was never meant to handle.
Reduced Home Value
Buyers, inspectors, and lenders often view active knob and tube as a major defect, which can slow negotiations and make a sale or refinance harder to complete.

Our Knob & Tube Rewiring Services
From full rewires near Alderwood Plaza to targeted upgrades around Horner Avenue and Brown’s Line, we handle the full scope of replacing unsafe legacy wiring in older Alderwood homes.
Full Home Rewire
We remove active knob and tube throughout the property and install a complete new wiring system designed for present-day lighting, receptacles, appliances, and household load.
Partial Rewire & Targeted Circuits
If only certain sections still contain active legacy wiring, we can isolate those runs and replace the specific circuits that still need correction.
Panel Upgrade
Many older homes need panel improvements at the same time so the new wiring has proper capacity, protection, and cleaner circuit organization.
ESA Permit & Inspection
We handle the ESA permit and coordinate inspection so the finished work has the documentation insurers, buyers, and lenders commonly ask for.
Insurance Assessment Letter
If your insurer needs quick confirmation, we can inspect the property and provide a written assessment showing what remains active and what work is required.
GFCI & AFCI Upgrades
We install the protective devices required for kitchens, bathrooms, bedrooms, exterior outlets, and other locations covered by current electrical code rules.
Attic Insulation Clearance
Where insulation is covering active knob and tube, we address the electrical replacement first so the attic can be upgraded safely afterward.
Pre-Sale Rewire
We help sellers remove a major electrical red flag before listing or closing so the transaction is less likely to stall over outdated wiring concerns.
