Knob & Tube Wiring

Assessment · Partial Remediation · Full Rewire · Winnipeg & Eastern Manitoba

⚡ It Was Good — For Its Time

Knob and tube wiring was the standard method of wiring homes in North America from the late 1800s through the 1940s. It was named for the ceramic knobs that held the wires in place and the ceramic tubes that protected them where they passed through wood framing. For its era, it was a genuine advancement — well-engineered for the electrical demands of the day.

And what were those demands? A toaster. A coffee percolator. A clothes iron. Maybe a radio. That's about it. Electricity was still considered a novelty by many, and the idea that a home might one day need to power a refrigerator, a washer and dryer, a dishwasher, a microwave, multiple televisions, computers, an electric vehicle, and a smart home system — that simply wasn't on anyone's radar.

Think about everything that's been invented since then. Every single one of those things runs on electricity. And in many older Winnipeg and Eastern Manitoba homes, it's all running through wiring that was designed for a coffee percolator and a lamp.

🔥 What's Working Against It Now

Knob and tube wiring has several serious factors working against it in a modern home:

• Time — The insulation on knob and tube wiring is rubber and cloth. After 80 to 100 years, that insulation becomes brittle — and in many cases, it's simply gone. Bare wire in your walls is not a question of if it becomes a problem. It's when.
• Insulation — Most homes of that era were insulated with wood shavings, sawdust, or similar combustible materials. Knob and tube wiring was designed to dissipate heat into open air — the moment you pack insulation around it, you take away its only cooling mechanism.
• No ground wire — Knob and tube has no grounding conductor. That means no protection against electrical shock and no compatibility with modern three-prong appliances and devices.
• Overloaded beyond design — The system was sized for a fraction of what a modern household demands. Decades of increasing load have stressed these circuits well beyond anything the original installer could have imagined.
• Amateur modifications — This is where things get truly dangerous. Over the decades, homeowners and unqualified handymen have spliced into knob and tube circuits to add outlets and circuits. These modifications — done without permits, without training, and without the right materials — are responsible for more fires than the original wiring ever was.

🏠 The Insurance Problem

If your home has knob and tube wiring, your insurance company either already knows — or they're about to find out. Many insurers in Manitoba will not provide coverage for homes with active knob and tube wiring. Others will insure it under strict conditions, charge significantly higher premiums, or require a licensed electrician's inspection before they'll renew your policy.

If you're buying or selling a home and knob and tube shows up on the inspection report, it becomes a negotiating issue at best and a deal-breaker at worst. Getting it addressed before you list — or before you close — is almost always the right move.

🔧 What We Do

We've done a lot of knob and tube rewires — full homes, partial remediation, and everything in between. Here's how we approach it:

• Full rewire — The permanent solution. All knob and tube is removed and replaced with modern wiring throughout the home. When it's done, you have a fully modern electrical system, no disclosure required when you sell, and no issues with insurance.
• Partial remediation — In some cases, knob and tube has already been replaced in parts of a home and only specific areas remain. Where the remaining original wiring is sound and accessible, partial remediation can be a cost-effective option. We'll assess the situation honestly and tell you whether partial work makes sense or whether a full rewire is the right call.

📋 Permits & Inspection

This work is permitted in the City of Winnipeg and throughout our service area. A licensed electrical inspection is part of every rewire we complete. That inspection is also what your insurance company needs to see — and what protects you when it comes time to sell.

💰 Manitoba Hydro HEEL Financing

A full knob and tube rewire qualifies for Manitoba Hydro's HEEL program — meaning you may be able to finance the work with no money down, paid back through your hydro bill. Endeavour Electric is a registered HEEL supplier. Ask us about it when you call.

💲 Pricing — How We Figure It Out

Every knob and tube rewire is quoted individually, but for a whole home rewire we use a straightforward formula — no mystery, no guesswork. Here's how it works:

We start by counting every device in the home that needs to be wired:

• Every light fixture
• Every switch
• Every receptacle
• Every smoke detector and carbon monoxide detector required by today's code

That total gets multiplied by $150 per device. From there we add for the specifics of your home:

• Smoke & CO detectors — approximately $100 each for the unit itself, on top of the base rate
• GFCI receptacles — an additional $25 each, required by code in kitchens, bathrooms, and other wet areas
• Arc fault circuit interrupters (AFCIs) — approximately $100 each; today's electrical code requires arc fault protection on almost every circuit in the home. If you want each bedroom or area on its own dedicated breaker, this is where that cost comes in
• Dryer and stove circuits — these require heavier wire and dedicated circuits. A stove circuit typically runs $300 to $900 or more depending on the size of the home and how far the wire needs to travel from the panel
• Dedicated receptacles — for a window air conditioner, chest freezer, or any single appliance you want on its own circuit, we count each one as two devices in the formula

When Don comes to quote your job he'll walk through the home, count everything up, and give you a firm number before any work starts. No surprises — just a clear price for a complete, permitted, inspected rewire.
