Types of Wiring
We Replace in Scarborough
Whether it is a single problem circuit or a full home rewiring, FlashPro Electric handles every type of residential wiring replacement in Scarborough and the GTA.
01

Knob and tube wiring becomes a serious fire hazard when insulation is placed over it, when the cloth covering deteriorates, or when modifications are made by non-licensed workers. Most home insurance companies in Scarborough refuse coverage or significantly raise premiums for homes with active knob and tube. FlashPro Electric fully removes the old wiring and replaces it with modern copper cable to Ontario Electrical Safety Code — ESA permit and inspection included.

Aluminum Wiring Repair
Typically found in Scarborough homes built between 1965 and 1975

Aluminum wiring is not inherently dangerous — the problem is the connections. Aluminum expands and contracts with heat more than copper, causing connections at outlets, switches and fixtures to loosen over time, which leads to arcing and fire risk. FlashPro Electric repairs aluminum wiring using approved methods — installing anti-oxidant compound and proper aluminum-rated connectors at every connection point. This satisfies most Scarborough insurance requirements without the cost of a full rewiring.
03
Full Home Rewiring
Complete wiring replacement — safer, modern and up to code
Full Home Rewiring
Complete wiring replacement — safer, modern and up to code
A full home rewiring replaces every circuit in your Scarborough home with modern copper cable, adds grounded three-prong outlets throughout, and includes AFCI and GFCI protection where required by code. The work typically takes two to five days depending on the size of the home and whether walls need to be opened. FlashPro Electric plans the work room by room to minimize disruption, restores power to as much of the home as possible each evening, and completes the project with a full ESA inspection and certificate.
04
Partial & Room-by-Room Rewiring
Targeted upgrades for renovations, additions or specific problem areas
Partial & Room-by-Room Rewiring
Targeted upgrades for renovations, additions or specific problem areas
Not every Scarborough home needs a full rewiring — sometimes only a kitchen, basement, addition or a single problem circuit needs to be replaced. FlashPro Electric handles partial rewiring projects during renovations, room additions or when a specific area shows signs of failing wiring. We match the new work to the existing system, ensure everything meets Ontario Electrical Safety Code, and pull the ESA permit for the scope of work involved.

Old Wiring Is the Silent
Fire Hazard in Older Scarborough Homes
Most homeowners never see their wiring until something goes wrong. Here is why it matters — and what we do about it.
Thousands of homes across Scarborough were wired decades ago — some as far back as the 1930s with knob and tube, and many between 1965 and 1975 with aluminum branch circuit wiring. The wiring itself is not always dangerous. The problem is what happens at the connection points over decades of heating, cooling and everyday use.
Connections at outlets, switches, light fixtures and panel terminals slowly loosen over time. A loose connection is where arcing and overheating happen, and that is where electrical fires begin. Cloth-covered wire insulation dries out. Aluminum connectors oxidize. Modifications made by non-licensed workers create new failure points. All of this stays hidden inside the walls until something goes wrong.
FlashPro Electric handles both accepted approaches for making old Scarborough wiring safe. A full home rewiring replaces every branch circuit with modern copper cable — the most comprehensive and long-term solution. Targeted aluminum wiring repair installs approved connectors with anti-oxidant compound at every connection point in the home, satisfying most insurance requirements without the disruption of a full rewiring. Every project includes an ESA permit and inspection.

Frequently Asked Questions
Everything you need to know about home rewiring, knob and tube removal and aluminum wiring repair in Scarborough and the GTA.
How do I know if my Scarborough home has knob and tube wiring?
Knob and tube wiring is most commonly found in Scarborough homes built before the 1950s. Signs include cloth-covered wires visible in the attic or basement, ceramic knobs and tubes running through the framing, two-prong outlets throughout the home, and no ground wire. A licensed FlashPro Electric electrician can inspect your home and confirm whether knob and tube wiring is present and what needs to be done.
Is knob and tube wiring dangerous and does it need to be removed?
Knob and tube wiring is not inherently dangerous when untouched, but it becomes a serious fire and safety hazard when insulation is placed over it, when it is modified by non-licensed workers, or when the cloth covering deteriorates with age. Most home insurance companies in Scarborough will not insure a home with active knob and tube wiring, or will significantly increase premiums. FlashPro Electric removes and replaces knob and tube wiring safely and up to current Ontario Electrical Safety Code standards.
What is aluminum wiring and why does it need to be repaired?
Aluminum wiring was commonly installed in Scarborough homes built between 1965 and 1975. The problem with aluminum wiring is not the wire itself — it is the connections. Aluminum expands and contracts with heat more than copper, causing connections at outlets, switches and fixtures to loosen over time. Loose connections cause arcing, overheating and fire risk. FlashPro Electric repairs aluminum wiring using approved methods — installing anti-oxidant compound and proper aluminum-rated connectors at every connection point throughout the home.
How long does a full home rewiring take in Scarborough?
A full home rewiring in Scarborough typically takes two to five days depending on the size of the home, the number of circuits and whether walls need to be opened. FlashPro Electric plans the work carefully to minimize disruption — we coordinate room by room and restore power to as much of the home as possible each evening. An ESA permit and inspection are included in every full rewiring project.
Will my home insurance accept the rewiring work done by FlashPro Electric?
Yes — all rewiring and aluminum wiring repair work performed by FlashPro Electric in Scarborough is done by licensed electricians, with an ESA permit pulled and a formal ESA inspection completed. The ESA inspection certificate is the document your insurance company requires to confirm the work meets Ontario Electrical Safety Code. We provide this certificate upon completion of every rewiring project.
