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

Replacing knob-and-tube wiring usually means a whole-home rewiring project, and Fix-it 24/7 provides upfront flat-rate pricing after an in-home assessment. The biggest cost driver is the size and layout of the home and how easy it is to access existing wiring without excessive wall or ceiling damage. We plan the work to reduce disruption, and on older homes we often phase circuits so essentials stay powered while we rewire. We also handle required permits and inspections and ensure the finished system meets current electrical code. We complete these projects across the Denver metro, including work in and around Lone Tree.

Typical factors that determine price:

• Square footage and number of circuits to rewire
• Access challenges in attics, crawlspaces, or finished plaster walls
• Need for an electrical panel upgrade to support modern loads
• Patch/repair scope after wiring is replaced

Final pricing is confirmed only after an on-site inspection by a licensed electrician.
