How Much Does Knob And Tube Wiring Replacement Cost?

Knob-and-tube wiring replacement cost is project-specific and confirmed only after an on-site assessment and a written proposal. Cost typically reflects the total scope, needed safety upgrades to meet current code, and the care required to protect finished walls and ceilings. We use a clear process—consultation, assessment, proposal, execution, inspection, and follow-up—so pricing stays transparent from start to finish. Our in-house electricians handle full rewires around Newton Highlands with a safety-first approach.

Key factors that change price:

• Square footage served and number of circuits to replace
• Access paths (attic/basement) versus fishing through plaster and lath
• Electrical panel capacity and any panel or service upgrade needs
• Required GFCI/AFCI protection and grounding improvements
• Patch-and-paint responsibilities after any openings
• Permit and inspection requirements in your jurisdiction
• Occupied versus vacant home scheduling and cleanup

Schedule an on-site assessment to get a firm price and plan that fits your home.
