Knob and Tube Replacement - KNT Electric

Toronto’s Premier
of Knob &
Tube Replacement

Knob and tube replacement and upgrading to modern, more conventional wiring, 100% copper wiring is often necessary and almost always a good idea. Why? Back in the day, knob and tube wiring was the standard practice for electricians installing residential wiring and circuitry. What has happened over time, however, is that the knob and tube wiring in vintage homes in Toronto suffers from wear and tear. The covering has dried out, cracked and/r crumbled – even chewed on by rodents. That means it’s nearing the end if its useful life.

Modern appliances & fixtures require that a bonding wire be connected to the outlets. Knob and tube wiring systems are missing this. If you have such a system, it’s time for a knob and tube wiring replacement upgrade to 100% copper wire.

Hard to find helpful and honest guys in trades, but KNT are those guys. Tim came to our house to review our breaker panel. A previous electrician said we would have to replace the whole thing ($3-4K) and I wanted to get someone else to confirm that. Tim was honest and said it just needed a little cleaning and rust removal as it wasn’t terrible. Walked me through for 10 minutes what I would have to do and didn’t charge us at all. Thanks again for you honesty.

“Tim and Bill were extremely helpful and knowledgable. The quote and the final invoice was so detailed and they were happy to explain the process and make recommendations. The daily team was very professional and worked efficiently to make the process as smooth as possible. They cleaned up every day and when all was finished, left us small neat patches to re-paint. We are SO thankful to have found”

“ Excellent work. Tim’s crew were professional in getting the work done on time as promised. As promised, most of their holes were the size of a golf ball and as invasive as possible. This was important to us as we wanted to minimize the cost of repairing our plaster walls. I would however recommend going with a professional taper to re-plaster the walls. All in all, no complaints.”
