Knob-and-Tube Wiring Removal in Barrie

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

How common is knob-and-tube wiring in Barrie homes?

It’s mostly found in Allandale and the older streets along the South Shore near downtown, in homes built before the 1950s. Newer Barrie subdivisions don’t have it.

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

Many Ontario insurers won’t 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.

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.
