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

The cost to replace knob-and-tube wiring is provided after an on-site evaluation, because price varies by home size, access conditions, and any required upgrades. Most projects involve running new grounded circuits, replacing outlets and switches, and addressing panel capacity if the existing system is undersized. Our team can integrate related work like sub-panels and whole-house surge protection within the same project scope, and we offer upfront pricing with a 5-year warranty on products and services. We regularly handle rewiring for older homes in the Crowley area with a clean, organized approach that respects your space.

For a precise quote, electricians look at:

• Square footage and circuit count to be replaced
• Attic/crawlspace access and wall/ceiling construction
• Panel upgrade needs and grounding/AFCI-GFCI requirements
• Patching/finish expectations after wire pulls

If you still have active knob-and-tube, avoid high-load devices on those circuits and schedule a licensed inspection to plan a safe replacement.
