Frequently Asked Questions

Electrical Wiring & Rewiring FAQs

How much does it cost to rewire a house in Hamilton?

+
The whole house rewiring cost depends on the size of the home, the number of floors, access to walls and ceilings, and whether the panel also needs upgrading. Replacing knob and tube wiring in a finished older home usually requires more work than rewiring during a renovation when walls are already open. We inspect the home and provide a clear quote before work begins.

Can you rewire a house without removing drywall?

+
In many cases, yes. With retrofit wiring, electricians can fish new cables through walls and ceilings from accessible areas such as attics and basements. Small access openings may still be needed, but this approach helps minimize drywall and plaster repairs when rewiring an older home.

How long does house rewiring take, and can I stay in my home?

+
A full home rewiring project can take several days to a few weeks depending on the size of the house and the complexity of the work. Many homeowners remain in the property while the work is completed. We plan the project by area so you know which rooms will be affected.

How do I know if my house has knob and tube wiring?

+
Knob and tube wiring was common in older Hamilton homes built before the 1950s. Signs can include ceramic knobs or tubes in unfinished basements and attics, two-prong outlets or older fuse boxes. Since wiring may be hidden behind walls, a professional knob and tube inspection is the best way to confirm whether it is still active.

Is knob and tube wiring illegal in Ontario, and will insurance cover my home?

+
Knob and tube wiring is not automatically illegal in Ontario. However, it may create challenges during renovations or insurance reviews. Some insurance companies may request an inspection, documentation or replacement depending on the condition of the wiring. We can inspect the system and explain the available options.

Does aluminum wiring need to be replaced, or can it be repaired?

+
Not always. Aluminum wiring from older homes can sometimes be addressed through approved remediation methods, including proper connectors and connection improvements. In other cases, a complete aluminum wiring replacement may be recommended. We inspect the system first and suggest the right solution.

What electrical work does a hot tub or pool need?

+
Hot tubs usually require a dedicated electrical circuit, GFCI protection and proper connection based on the equipment requirements. Pool electrical systems may also require additional safety measures. We check your panel capacity, complete the wiring and arrange the required inspection.
