We Know The Annex Most calls fall into four buckets. Each has a code-driven answer and an insurance-ready paper trail. ### Active Knob-and-Tube on Insurance Renewal Howland and Madison Avenue Edwardian semis still carry active knob-and-tube circuits, and most Ontario insurers refuse to renew without remediation. Full or staged rewire with plaster preservation, ESA Certificate of Acceptance, and a sample insurer letter. [Active Knob-and-Tube on Insurance Renewal →](/knob-and-tube-wiring-replacement/) ### Original Ungrounded Circuits in Edwardian Homes 1910 and 1915 Bedford Road and Huron Street homes commonly run on two-prong ungrounded receptacles. Modern AFCI and GFCI protection plus a grounding upgrade strategy that doesn't require ripping out heritage trim or original plaster.

The Annex Local Expertise ## Heritage Electrical Expertise in The Annex The Annex holds one of the highest concentrations of active knob-and-tube wiring in the GTA. Edwardian and Victorian homes built between 1890 and 1925 along **Howland Avenue**, **Madison Avenue**, and **Bedford Road** still carry original ungrounded circuits in many cases, and Ontario insurers are pulling coverage or demanding remediation documentation. Heritage work here requires careful technique. Near the **University of Toronto** campus and in pockets around **Casa Loma**, many homes carry Heritage Toronto designations requiring preservation of original plaster, trim, and millwork. We use minimal-cut lath fishing and hand tools near original mouldings. Our team sequences the work room-by-room so you stay in the home throughout the project, typically 5-8 days for a full rewire. The ESA Certificate of Acceptance we provide is the document insurers require for renewal. ### Landmarks & Surrounding Area - University of Toronto (St. George Campus) - Royal Ontario Museum - Spadina House Museum - Casa Loma - Bloor Street Village ### Access Routes An inner-city neighbourhood with direct TTC subway access at Spadina, Bathurst, and Bay stations on the Bloor-Danforth line. ### Areas We Serve in The Annex - ✓ Spadina-Bloor - ✓ Casa Loma adjacent - ✓ Howland Avenue - ✓ Madison Avenue - ✓ Bedford Road - ✓ Huron Street - ✓ Walmer Road ![Typical The Annex housing stock and electrical environment](/images/locations/location-the-annex-local.webp) Customer Reviews ## What Annex Homeowners Say Recent The Annex jobs across the neighbourhoods we cover most often. Average **4.9/5** across our GTA work. > "Our 1912 Howland Avenue semi had active knob-and-tube and the insurance renewal letter to prove it. The team did the full rewire in seven days, room-by-room, and our original plaster came through almost untouched. ESA Certificate of Acceptance closed the insurance file." Sarah M. Howland Avenue, The Annex > "Walmer Road home with the original 1950s Federal Pacific Stab-Lok panel still in service. They quoted a 200A panel swap, coordinated Toronto Hydro for the cut and reconnect, and we were back online by 3pm. ESA paperwork came through clean." David B. Walmer Road, The Annex > "Plaster ceiling LED pot lights in our 1908 Madison Avenue home. They used IC-rated remodel cans, cut minimally, patched what they did open, and the ceiling looks original. Heritage details survived the install." Elizabeth K. Madison Avenue, The Annex The Annex FAQ ## The Annex Electrical FAQs ### How quickly can your team reach Howland or Madison Avenue in The Annex? + The Annex is an inner-city neighbourhood. Our team typically arrives in 25-35 minutes for non-emergency calls. Emergency response is available 24/7. ### My 1910 Annex Victorian has knob-and-tube wiring. Can I stay in the house during the rewire? + Yes. We sequence the rewire room-by-room so you can stay in the home throughout the project. Most Annex full-home rewires take 5-8 days. Power is restored each evening to the rooms not being worked on. ### Will removing knob-and-tube wiring damage the original plaster walls in my Annex home? + Our heritage technique minimises wall damage. We use minimal-cut lath fishing and hand tools near original mouldings. Plaster patching is included where cuts are unavoidable. Many clients report less visible damage than they expected. ### My insurer is threatening to cancel over knob-and-tube wiring. What documentation do I get after the rewire? + After a full knob-and-tube removal, we provide an ESA Certificate of Acceptance, the document Ontario insurers require as proof of remediation. We also provide a sample insurer letter explaining the scope of work completed. ### Do you do electrical safety inspections for Annex homes before purchase? + Yes. Pre-purchase electrical inspections in The Annex are common given the age of the housing stock. Our written deficiency report flags knob-and-tube wiring, Federal Pacific panels, ungrounded outlets, and any unpermitted work, the items that come up at closing.
