How much does knob and tube removal cost in Ottawa?
Knob and tube removal in Ottawa typically costs $400-800 per circuit, with most homes requiring $8,000-15,000 for complete rewiring depending on size and complexity.
The cost varies significantly based on several factors. For partial removal of individual circuits, expect $400-800 per circuit including new wiring, outlets, and switches. However, most knob and tube homes built before 1950 require complete rewiring since the old system lacks proper grounding and doesn't meet current Ontario Electrical Safety Code (OESC) requirements.
Complete home rewiring costs in Ottawa range from $8,000-15,000 for a typical 1,500 square foot home. Larger homes or those requiring extensive drywall repair can reach $20,000 or more. The price includes new 14 AWG and 12 AWG copper wiring, modern electrical panel upgrade to 200A service, GFCI protection in required areas, and all necessary ESA permits and inspections.
Insurance complications often drive the urgency for removal. Many Ottawa insurance companies now refuse coverage or charge significant premiums for homes with knob and tube wiring, especially when combined with blown-in insulation. This combination creates a serious fire hazard since knob and tube relies on air circulation for cooling, which insulation blocks.
The removal process requires ESA permits for each circuit being replaced, and all work must be completed by licensed electricians. Most projects take 3-5 days for complete rewiring, with ESA inspections scheduled throughout the process. Never attempt DIY knob and tube removal - it's illegal in Ontario and extremely dangerous due to the lack of proper grounding and outdated safety standards.
Additional costs to consider include temporary electrical service during major rewiring ($300-500), drywall patching where new wiring is run ($1,000-3,000), and potential panel location changes if your current panel doesn't meet modern clearance requirements under the OESC.
For an accurate assessment of your knob and tube removal project, schedule a consultation with ESA-licensed electricians who can evaluate your specific situation and provide detailed quotes. The investment in proper rewiring not only ensures safety but often pays for itself through reduced insurance premiums and increased home value.
