Frequently Asked Questions (FAQs)
What kind of wiring is considered old and unsafe?
Knob and tube wiring was primarily used for homes at the beginning of the 20th century, and is now considered obsolete due to its rubberized cloth insulation and its suspended nature. Aluminum wiring, too, although considered to be safer than its predecessor, has over time come to be considered less than ideal due to its softness, which can cause it to fray and come loose from terminals. This creates a need for aluminum wiring to be inspected every 3-5 years. Upgrading to copper wiring will allow you to save money on maintenance and inspection, while also ensuring that your home will be safer.
What other factors can affect the cost of replacement wiring?
Other additional costs can include the amount of materials that will be needed (including wiring, switches, bolts, etc.), acquiring any permits, and opening up the walls (ranging a few thousand depending on the current state of your home), which is why it’s often recommended to have wiring upgraded while in the midst of renovations, in which walls will already be down to allow you to save money on labour.
Will my home be less likely to be insured with outdated wiring?
Most insurance companies and mortgage lenders will likely be hesitant to deal with houses that are considered high risk or unsafe due to outdated wiring. Especially with very old wiring systems like knob and tube wiring, securing financing and obtaining a mortgage for these homes will be almost impossible until sufficient electrical upgrading has been done. The longer it’s left to the last minute, the more damage can compound, costing you money in the long-run.
