How much does it cost to replace knob and tube wiring?

Replacing knob and tube wiring is quoted after an on-site evaluation because total cost varies by your home’s size, access, and whether your electrical panel needs upgrades. Most projects cost more when walls or attics are hard to reach and when the system needs added capacity for today’s loads. We routinely complete full rewires alongside related work like lighting and panel upgrades throughout the Sandy Level area. All electrical work we perform is backed by our 100% satisfaction guarantee.

Primary factors that set the price:

• Total square footage and number of circuits to replace
• Accessibility of attics, crawl spaces, and concealed runs
• Panel/capacity upgrades or new dedicated circuits for modern appliances
• Scope decisions: partial areas vs whole-home, plus add-ons like lighting or EV charging

If you notice sparks, burning smells, shocks, or frequent breaker trips, stop using the affected circuit and call a licensed electrician immediately.
