Frequently Asked Questions (FAQs)
What can knob and tube or aluminum wiring be upgraded to?
Nowadays, most newer homes are being wired with copper. Copper wiring is also the first choice of electrical experts for replacement wiring. Since its price has come down significantly from the 70s, copper is now regarded as one of the most cost-effective ways to reduce wiring expenses. Allowing for smaller conductors to transit larger electrical loads, copper has a much higher tensile strength compared to aluminum, making it a viable option for increasing demands for electricity.
Can I upgrade old wiring myself?
Wiring is often seen as a simple and accessible system — however, electrical changes (especially to wiring) can require a lot of specialized knowledge. The rigorous requirements of becoming an electrician demonstrate this, so it’s not recommended to take on such a large task on your own. Faulty wiring is one of the top causes of house fires, with homeowners insurance often being voided for negligence. Not only can hiring a professional prevent this, but it is also beneficial for convenience purposes, allowing you peace of mind and assurance that the job will be done right the first time.
What happens to knob & tube and aluminum wiring as it ages out?
Knob and tube wiring is wrapped in a rubberized cloth, which can crack and flake off over time. This leaves the wires exposed to the elements, making it a shock and fire hazard. There is also the risk of it overheating if hidden behind the walls. Aluminum wiring is recommended to be inspected every 3-5 years by the ESA since due to its softness, it has a tendency of becoming undone. The maintenance and inspection costs often outweigh the benefits, which is why most homeowners prefer to replace it.
