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

Replacing knob and tube wiring cost varies by home and is confirmed after an on-site assessment. The biggest swing is usually total circuit length and how easy it is to access walls, attics, and crawlspaces. Scope can range from targeted rooms to a full rewire, and code updates like grounding and arc-fault protection may be added; panel upgrades are sometimes bundled for capacity. Our licensed electricians are trained, certified, and follow Brevard County codes on projects like this. In many older homes, the spend is more about fishing new cable through finished spaces than the wire itself. If you’re seeing frequent blown fuses, warm outlets, or brittle cloth insulation, treat it as urgent.

Key factors that set the final price:

• Home size and number of circuits to replace
• Access conditions (plaster vs drywall, insulation, attic/crawl clearance)
• Need for panel upgrades (100A–400A), meter or fuse-to-breaker conversion
• Repairs after wiring (patch/paint) and scheduling constraints

Schedule an in-home evaluation so we can map circuits, check panel capacity, and provide a firm written quote.
