Knob-and-Tube Wiring Removal in Mississauga

How Knob-and-Tube Wiring Removal Works

1. 1

   Wiring assessment

   We trace your home’s circuits to identify exactly which areas are still on knob-and-tube versus already updated, and check panel capacity for the new wiring.

2. 2

   Rewire plan & permit

   We scope a partial or full rewire based on what we find, and pull the ESA permit before any work begins.

3. 3

   Removal & rewiring

   We remove the old wiring and run new copper circuits, working through existing wall and ceiling cavities to keep drywall disruption to a minimum.

4. 4

   ESA inspection & documentation

   Once inspected and approved, you get a certificate of inspection for your insurer or for your records.

Frequently Asked Questions

Are older homes near Port Credit’s main street likely to have knob-and-tube wiring?

Some are, particularly homes that predate Mississauga’s major postwar subdivision growth. We assess the actual wiring rather than assuming based on the neighbourhood alone.

Is knob-and-tube ever a concern in Meadowvale?

No, Meadowvale’s homes were built well after knob-and-tube wiring was standard, so it isn’t something homeowners there typically need to worry about.

My older Clarkson lakeside home is being assessed for insurance, what should I expect?

We’ll trace the home’s circuits to identify exactly which, if any, are still on knob-and-tube, then provide documentation your insurer can use either way.

How do I know if my home still has knob-and-tube wiring?

Knob-and-tube is visible in unfinished attics and basements as ceramic knobs and tubes with cloth-insulated wiring. Many homes have a mix of knob-and-tube and updated wiring, so a proper inspection is the only way to know for certain.

Does my home insurance require knob-and-tube removal?

Many insurers in Ontario will not write or renew a policy on a home with active knob-and-tube wiring, or will require it to be inspected and certified. We provide documentation your insurer can use either way.

Do you need to open every wall to remove knob-and-tube wiring?

Not always. We route new wiring through existing wall and ceiling cavities wherever possible, and will tell you upfront if a section genuinely requires opening drywall.

Can knob-and-tube wiring be replaced in stages?

Yes, a partial rewire is common, especially if only certain circuits or areas of the home are still on knob-and-tube. We can also plan a phased full rewire if that fits your budget better.

How long does a knob-and-tube rewire take?

A single-circuit or partial rewire can often be done in a day or two, while a full-home rewire typically takes several days depending on the size and layout of the house.

How much does knob-and-tube wiring removal cost?

Cost depends on how much of the home needs rewiring and how accessible the walls and ceilings are. We provide a clear quote after assessing your home’s actual wiring.
