The answer to 'rewiring replacement schedule' is that the recommended schedule for rewiring a home is every 25-40 years. Older homes with knob-and-tube or aluminum wiring should be rewired sooner, around 20-25 years. Rewiring is an important home maintenance task to ensure your electrical system is safe and up to code.
The lifespan of wiring depends on the materials used, how the wiring was installed, and how much use it gets over time. Older wiring materials like knob-and-tube or aluminum can become a fire hazard as they age. Rewiring your home completely is the best way to upgrade to modern, safer electrical standards.
